Concrete batching plant 100 m³/h: what you need to know before purchasing

21 September 2026

Concrete batching plant 100 m³/h — is an industrial installation for enterprises that need to consistently produce large volumes of ready-mixed concrete or supply concrete mix for their own construction, road, and infrastructure projects. The rated 100 m³/h does not mean that the enterprise will receive exactly 100 m³ of ready concrete every hour throughout the entire working day: the actual output depends on the batch volume, cycle duration, dosing, aggregate feeding, cement loading, logistics, and organization of vehicle operations. For KARMEL 100K, the basic capacity is 100 m³/h, using aggregate storage bins 4×20 m³, silos with capacities from 75 to 500 t, and a mixer 3000/2000; the installed power is about 154 kW.

Therefore, before purchasing a concrete batching plant 100 m³/h, it is necessary to consider not only the rated capacity but the entire production complex: how much concrete needs to be produced per day, how much cement to store on site, how aggregates will be fed, what electrical power is required, how many concrete mixers will operate simultaneously, and how the loading will be organized.

Who needs a concrete batching plant 100 m³/h?

A CBP with a capacity of 100 m³/h is usually considered by enterprises that require significant and stable concrete output.

These may include:

  • ready-mixed concrete producers;

  • construction companies;

  • road construction enterprises;

  • manufacturers of reinforced concrete structures;

  • enterprises building large industrial facilities;

  • infrastructure projects;

  • manufacturers of paving slabs and other concrete products;

  • enterprises planning to work simultaneously with several construction sites.

But the key question before purchasing is not «do I need a plant with 100 m³/h?», but:

«What is the actual daily volume of concrete I need to produce and how often will the plant operate at peak load?»

It is precisely this that determines whether a 100 m³/h installation will be economically justified.

How much concrete can be produced at a 100 m³/h plant?

If we take the rated capacity of 100 m³/h, mathematically we get:

100 m³/h × 8 hours = 800 m³ per shift.

For 10 hours of operation:

100 m³/h × 10 hours = 1000 m³.

But this is a theoretical calculation.

In actual operation, some time is taken up by:

  • loading;

  • mode switching;

  • recipe changes;

  • dosing;

  • maintenance;

  • cleaning the mixer;

  • vehicle movement;

  • technological pauses;

  • material replenishment.

Therefore, designing a business model solely based on the indicator of 100 m³/h is incorrect.

To calculate capacity, it is necessary to consider the utilization factor of the installation.

For example, if the average actual capacity is 70–80% of the rated, then for an 8-hour shift the approximate output will be:

Load capacity Average capacity 8 hours of operation
60% 60 m³/h 480 m³
70% 70 m³/h 560 m³
80% 80 m³/h 640 m³
90% 90 m³/h 720 m³
100% 100 m³/h 800 m³

These are not universal standards but an example to understand the economics. The actual coefficient depends on the specific technological scheme and production organization.

Is 100 m³/h enough for 500 m³ of concrete per day?

Yes.

If the enterprise needs to produce about 500 m³ of concrete per working shift, a plant with 100 m³/h has sufficient rated capacity margin.

For example:

500 m³ ÷ 100 m³/h = 5 hours of theoretical operation.

This leaves time for technological pauses and uneven order flow.

For an enterprise that regularly produces 700–800 m³ per shift, a 100 m³/h plant will already operate much closer to its calculated load.

If the business plans to produce 1000–1200 m³ of concrete daily, it is necessary to evaluate not only the CBP capacity but also the number of working hours, transport, cement stock, aggregate loading, and the possibility of operation without long downtime.

Concrete Batching Plant 100 m³/h: main characteristics

The typical configuration of a plant with such capacity should ensure coordinated operation of several systems:

  1. aggregate storage bins;

  2. dosing units;

  3. conveyor;

  4. cement silos;

  5. screw conveyors;

  6. water dosing system;

  7. mixer;

  8. pneumatic system;

  9. automation;

  10. filtration system;

  11. control system.

If one of these units does not meet the required capacity, the actual output of the entire plant may be lower than the rated one.

That is why 100 m³/h is a characteristic of the entire technological system, not just the mixer.

What mixer is needed for a concrete batching plant 100 m³/h?

This is one of the key points of the configuration.

For a plant of 100 m³/h, it is necessary to correlate:

  • useful batch volume;

  • cycle time;

  • number of batches per hour;

  • mixer type;

  • characteristics of the concrete mix.

KARMEL 100K uses a mixer of size 3000/2000.

The designation 3000/2000 in this case is related to the geometric and working volume of the mixer: approximately 3000 liters total volume and 2000 liters working batch.

That is, one cycle yields approximately 2 m³ of ready mix.

To achieve 100 m³/h, the system must provide the corresponding number of cycles taking into account the actual dosing, mixing, and discharge time.

That is why when comparing two plants at 100 m³/h, it is necessary to look not only at the catalog label but also at:

  • batch volume;

  • cycle duration;

  • mixer type;

  • drive power;

  • loading system;

  • real dosing organization.

Planetary, twin-shaft or rotary mixer?

For a capacity of 100 m³/h, different types of mixers can be used.

The choice depends on the recipe and the final product.

Twin-shaft mixer

Suitable for intensive mixing and widely used in ready-mix concrete production.

Its strong point is high mixing intensity and the ability to work with various recipes.

Planetary mixer

Often used where high quality and homogeneity of the mix are required.

It can be especially interesting for the production of concrete products and special mixes.

Rotary mixer

Can be used in appropriate technological configurations and has its own design features.

Therefore, the choice of mixer should not be made on the principle of "which type is better," but based on the recipes, capacity, and technology of the specific enterprise.

KARMEL 100K: what is included in the configuration?

KARMEL 100K is a stationary conveyor concrete batching plant with a capacity of 100 m³/h.

Basic characteristics of the model:

Parameter KARMEL 100K
Capacity 100 m³/h
Aggregate storage bins 4×20 m³
Mixer 3000/2000
Cement silos 75–500 t
Feeding type chevron conveyor belt
Installed power about 154 kW
Automation PLC
Remote control provided
Dosing automatic
Filtration integrated cleaning system

The specific configuration may vary depending on the technical assignment, recipe, number of cements, and site features.

Four bins of 20 m³: why are they needed?

For a plant of 100 m³/h, not only the mixer capacity is important but also a sufficient reserve of aggregate materials.

KARMEL 100K provides a configuration of 4×20 m³.

This allows organizing separate storage of different fractions.

For example:

  • sand;

  • crushed stone 5–10 mm;

  • crushed stone 10–20 mm;

  • other fraction.

The specific distribution depends on the enterprise's recipes.

Four sections also allow working with several recipes without constant readjustment of the aggregate feeding system.

Is it possible to install more bins?

Yes, the configuration should be determined not only by the standard catalog.

If the enterprise works with a large number of fractions, increasing the number of bins can be considered.

This makes sense if:

  • it is necessary to use more types of aggregates;

  • there are different recipes;

  • the enterprise produces special concretes;

  • it is necessary to reduce the number of readjustments.

But increasing the number of hoppers also means a larger area, more complex logistics, and higher cost.

Therefore, the optimal configuration should be determined based on actual recipes.

How many silos are needed for a 100 m³/h concrete batching plant?

One of the most important elements of the complex is the cement silos.

For KARMEL 100K, silo options from 75 to 500 tons are provided depending on the configuration.

But the question is not only how many tons of cement can fit on the site.

It is necessary to determine:

  • daily cement consumption;

  • number of cement grades;

  • delivery frequency;

  • capacity of vehicle transport;

  • reserve for weekends and delivery delays;

  • number of recipes.

How to calculate cement stock?

Conditional example.

Suppose the plant produces:

600 m³ of concrete per day.

Average cement consumption — conditionally:

300 kg per 1 m³.

Then the daily requirement is:

600 × 300 kg = 180,000 kg

or:

180 tons of cement per day.

In this situation, a 75-ton silo obviously will not provide the full daily stock.

Therefore, it may be necessary to have:

  • several silos;

  • larger total capacity;

  • regular replenishment during the day.

This is just an example. Actual cement consumption depends on concrete classes, recipes, admixtures, and strength requirements.

Why are two or more silos often more practical than one large one?

If the enterprise works with several types of cement, one silo limits technological capabilities.

For example:

Silo No. 1 — cement type A

Silo No. 2 — cement type B

Silo No. 3 — reserve

Thus, the enterprise gains more freedom in recipe formulation.

In addition, reserve capacity reduces dependence on the exact cement delivery date.

For industrial production, this is often more important than the maximum capacity of a single silo.

Electricity for a 100 m³/h concrete batching plant

Before ordering the CBP, it is necessary to obtain from the manufacturer a complete electrical balance.

For KARMEL 100K, the declared installed power is approximately 154 kW.

But it is not advisable to conclude:

“I only need a connection exactly for 154 kW.”

Installed power is the sum of the nominal powers of electric motors and other equipment, while actual consumption depends on the operating mode.

In addition, reserve must be taken into account.

What consumes electricity at the CBP?

Main consumers:

  • mixer electric motor;

  • belt conveyors;

  • screw conveyors;

  • compressor;

  • vibrators;

  • gates;

  • dosing systems;

  • ventilation and filtration;

  • auxiliary equipment;

  • control system.

The greatest load is usually associated with the drives for mixing and material transportation.

What electrical power should be planned?

Correct approach:

installed power + reserve + analysis of starting loads.

For a specific project, the electrician must calculate:

  • nominal power;

  • maximum simultaneous load;

  • starting currents;

  • voltage;

  • grounding system;

  • protection;

  • cable lines;

  • transformer substation.

If the enterprise plans to operate the CBP, compressors, pumps, lighting, repair equipment, and other consumers simultaneously, the electrical system must be calculated for the entire facility, not only for the concrete batching plant.

Is a separate transformer substation needed?

It depends on the existing infrastructure.

If the enterprise already has sufficient electrical power, a new input and appropriate distribution equipment may be sufficient.

If the existing network does not allow providing the required load, it is necessary to provide for:

  • a new transformer substation;

  • power increase;

  • new cable input;

  • distribution panel.

This issue must be resolved before installing the concrete batching plant, not after equipment delivery.

Logistics of aggregates for CBP 100 m³/h

At a capacity of 100 m³/h, logistics becomes critical.

If the plant produces 600 m³ of concrete per day, hundreds of tons of raw materials pass through it.

It is necessary to organize:

quarry / storage → loading → transport → hoppers → dosing → mixing → concrete mixer truck.

Any bottleneck in this chain can reduce the actual productivity.

How much aggregate is needed?

On average, about 1.8–2.2 t of main components may be required per 1 m³ of concrete, depending on the recipe.

For a conditional calculation, we take 2 t.

If the plant produces 600 m³ per day:

600 × 2 = 1200 tons of materials per day.

This is already a serious logistics flow.

Therefore, it is necessary to plan in advance:

  • access for dump trucks;

  • unloading area;

  • loader working front;

  • aggregate stock;

  • roads inside the enterprise;

  • water drainage;

  • site cleaning.

How to feed aggregates?

For a stationary conveyor plant, one of the common solutions is feeding aggregates by belt conveyor.

The advantage of this scheme is the possibility to organize continuous material supply from hoppers to the mixing unit.

KARMEL 100K uses exactly the conveyor scheme.

It is especially appropriate for enterprises where:

  • the plant operates many hours per day;

  • high productivity is required;

  • there is a constant flow of orders;

  • the site allows placement of the technological line.

What site is needed for a concrete plant 100 m³/h?

The required area cannot be determined only by the size of the CBP itself.

It is necessary to consider:

  • concrete batching plant;

  • silos;

  • aggregate storages;

  • roads;

  • maneuvering zone;

  • weighing area;

  • administrative premises;

  • space for concrete mixer trucks;

  • washing zone;

  • drainage;

  • electrical equipment.

Therefore, before designing, the manufacturer must obtain:

  • site plan;

  • relief;

  • connection points;

  • entry points;

  • traffic direction.

Loading height of concrete mixer truck

For a stationary concrete plant, it is important that the unloading height allows convenient loading of concrete mixer trucks.

In stationary conveyor CBPs KARMEL, the unloading height is approximately 3.8–4.15 m, depending on the configuration.

This should be considered together with:

  • mixer height;

  • road surface level;

  • entry possibility;

  • turning radius.

How many concrete mixer trucks are needed for a 100 m³/h plant?

This question is often underestimated.

If the CBP produces 100 m³/h, but the enterprise does not have enough mixers, the plant will have to wait for transport.

Conditionally:

  • one concrete mixer truck — 8 m³;

  • the plant produces 100 m³/h.

Theoretically, it is necessary to ship about:

100 ÷ 8 = 12.5 mixers per hour.

That is approximately one full mixer every 4.8 minutes.

But if the mixer after unloading has to travel far to the construction site and return, one vehicle is not enough.

The number of transport vehicles must be determined by:

  • concrete mixer truck volume;

  • distance to the site;

  • loading time;

  • travel time;

  • unloading time;

  • traffic situation.

Therefore, CBP productivity and fleet logistics productivity must be balanced.

Is automation needed at a 100 m³/h plant?

For a plant of such capacity, automation is practically a basic requirement for stable production.

The operator must be able to:

  • select the recipe;

  • control dosing;

  • see component weights;

  • control silo levels;

  • start and stop equipment;

  • see emergency signals;

  • keep production records.

KARMEL 100K uses a PLC control system, and remote control capability is also provided.

Why is dosing accuracy critical?

When producing hundreds of cubic meters of concrete per day, even a small error accumulates.

For example, if 300 kg of cement is conditionally used in each cubic meter, with a production of 600 m³ per day, this is:

180 tons of cement.

Therefore, dosing error simultaneously affects:

  • cost price;

  • strength;

  • recipe stability;

  • cement consumption;

  • quality of the finished concrete.

Automated dosing allows controlling this process much more accurately than manual component feeding.

Cement dust filtration

When operating silos and loading cement, dust is generated.

For an industrial CBP, an appropriate filtration system must be provided.

KARMEL configurations use dust cleaning systems integrated into the equipment.

When designing, it is necessary to consider:

  • silo filter;

  • ventilation;

  • tightness of connections;

  • filter service location;

  • dust collection system.

This is important not only from an environmental point of view but also for the normal operation of the equipment itself.

Winter operation of a concrete batching plant 100 m³/h

For Ukraine, this item must be considered already at the ordering stage.

Low temperatures affect:

  • water;

  • aggregates;

  • pneumatics;

  • pipelines;

  • cement;

  • concrete mix.

Therefore, for year-round operation, a winter package may be required.

Depending on the specific configuration, it may include:

  • water heating;

  • thermal insulation;

  • pipeline protection;

  • heating of critical units;

  • winter version of the control system.

If the CBP will operate all year round, the winter package must be included in the technical specification immediately.

How much does a concrete batching plant 100 m³/h cost?

The cost of a plant with 100 m³/h capacity cannot be correctly determined solely by productivity.

The final price is influenced by:

  • type of CBP;

  • type of mixer;

  • number of hoppers;

  • hopper volume;

  • number of silos;

  • silo capacity;

  • automation;

  • filtration system;

  • winter package;

  • metal structures;

  • conveyors;

  • installation;

  • commissioning;

  • delivery;

  • foundation and construction works.

For example, KARMEL 100K with four 20 m³ hoppers and two silos will have a different configuration than a plant with the maximum number of silos and additional equipment.

Therefore, the query «how much does a concrete batching plant 100 m³/h cost?» without a technical specification gives a very approximate answer.

What is included in the budget besides the CBP itself?

This is especially important when planning investments.

The overall budget can be conditionally divided into:

1. Main equipment

The concrete batching plant itself.

2. Cement facilities

Silios, screw conveyors, filters, compressor equipment.

3. Aggregates

Hoppers, conveyors, storage yards.

4. Electrical

Substation, cables, panels, connections.

5. Construction part

Foundations or site preparation, roads, drainage.

6. Installation

Installation works and start-up.

7. Logistics

Equipment delivery.

8. Vehicle fleet

Concrete mixers, loaders, dump trucks.

That is why the price of the CBP and the total investment in the concrete unit are not the same thing.

How long does installation take?

For stationary KARMEL plants, the standard declared installation and equipment start-up period is about 10 days after site preparation, depending on the specific configuration and project conditions.

But this does not mean that the entire project from contract signing to the first cubic meter of concrete will take 10 days.

Additional time must be added for:

  • site preparation;

  • foundations or other base;

  • electrical connection;

  • utility connections;

  • delivery;

  • assembly;

  • silo installation;

  • automation check;

  • commissioning.

Most often, it is the readiness of the site that determines the launch schedule.

Is a foundation required for a concrete batching plant 100 m³/h?

For a stationary CBP, it is necessary to evaluate the structural solution of the specific plant and local conditions.

It is necessary to consider:

  • soil type;

  • load;

  • structure height;

  • silios;

  • seismic and wind loads;

  • local construction requirements.

Decisions cannot be transferred from one site to another without calculation.

That is why the manufacturer must provide technical requirements for the foundation and loads.

KARMEL 100K: which enterprises is it suitable for?

KARMEL 100K makes sense to consider for enterprises that:

  • produce hundreds of cubic meters of concrete per day;

  • work with ready-mix concrete;

  • serve several construction sites;

  • require stable stationary productivity;

  • have a constant flow of aggregates;

  • can provide appropriate electrical power;

  • plan plant operation over a long period.

For a small enterprise with a need of 100–200 m³ of concrete per day, such a plant may be excessive.

In this case, it is worth considering lower productivity — for example, 30, 40, or 60 m³/h.

When can 100 m³/h be insufficient?

If the enterprise plans:

  • more than 800–1000 m³ per shift;

  • several simultaneous large construction sites;

  • continuous production over a long time;

  • a large fleet of concrete mixers;

there may be a need for higher productivity or a different production organization.

In this case, it is necessary to compare:

one plant of 100 m³/h

versus

a plant of higher productivity

or

two independent production lines.

The latter option may make sense when production redundancy is critically important.

One plant of 100 m³/h or two smaller ones?

This is already a question of business model.

For example, the enterprise may compare:

  • one CBP 100 m³/h;

  • two CBPs of 50 m³/h each.

The first option has less equipment duplication.

The second — potentially greater flexibility and redundancy.

Comparison should be made based on:

  • CAPEX;

  • OPEX;

  • personnel;

  • area;

  • electricity consumption;

  • service;

  • downtime risk;

  • logistics;

  • future expansion.

There is no universal solution for all enterprises here.

What to check before buying a concrete batching plant 100 m³/h?

Concrete batching plant 100 m³/h: summary

Concrete batching plant 100 m³/h is a solution for enterprises with serious production volume, but it cannot be evaluated only by the rated productivity figure.

Before purchase, it is necessary to calculate at least:

  1. required daily output;

  2. number of working hours;

  3. real cycle productivity;

  4. batch volume;

  5. number and capacity of hoppers;

  6. cement reserve;

  7. number of silos;

  8. electrical load;

  9. aggregate logistics;

  10. number of concrete mixers;

  11. winter operation;

  12. installation and commissioning.

KARMEL 100K in this case is a stationary conveyor solution at 100 m³/h with 4×20 m³ hoppers, 3000/2000 mixer, silos from 75 to 500 t, automatic dosing, PLC control, and installed power of about 154 kW.

In practice, the most important thing is not just to buy a CBP labeled "100 m³/h", but to form a configuration in which the mixer, dosing units, silos, conveyors, electricity, and transport work as one system.

If the enterprise realistically plans to produce 500–800 m³ of concrete per shift, a plant of this class can provide the necessary capacity reserve. However, if the actual demand is significantly lower, it is worth comparing the economics with a plant of lower capacity. Conversely, if the requirement exceeds 800–1000 m³ per shift, it is necessary to separately calculate the capacity of the entire production and logistics system.

FAQ

How much concrete can a 100 m³/h concrete batching plant produce in a day?

Theoretically, up to 800 m³ in 8 hours. The actual daily output will be lower or close to this value depending on the cycle duration, technological pauses, recipe changes, material loading, and shipment organization.

What mixer is required for a 100 m³/h concrete batching plant?

It depends on the technology. For KARMEL 100K, a 3000/2000 mixer with a working volume of about 2 m³ is used. When choosing, it is necessary to consider not only the volume but also the cycle time and type of concrete.

How many silos are needed for a 100 m³/h CBP?

There is no universal number. For KARMEL 100K, silo configurations from 75 to 500 t are available. The quantity should be determined based on daily cement consumption, the number of its types, and the delivery schedule.

What power is required for a 100 m³/h concrete batching plant?

For KARMEL 100K, the declared installed power is about 154 kW. When designing the power supply, it is additionally necessary to consider simultaneous loads, starting currents, and consumers of the entire production site.

How much does a 100 m³/h concrete batching plant cost?

The price depends on the configuration: mixer, hoppers, silos, automation, winter package, filtration, installation, delivery, and other components. Therefore, the correct price can be determined after forming the technical specification.

Is a 100 m³/h plant needed for a small concrete producer?

If the demand is only 100–200 m³ per day, a plant of such capacity may have an excessive reserve. In this case, it is advisable to compare its economics with a CBP of 30–60 m³/h.
