1. KARMEL Belt Conveyors

Purpose:

✅ Transportation of sand, crushed stone, cement, dry building mixes, coal, grain crops.
✅ High productivity in moving materials over distances up to 200 meters.
✅ Used at concrete mixing plants, quarries, and industrial enterprises.

Features of belt conveyors:

🔹 Load capacity from 5 to 500 tons/hour.
🔹 High-strength belts (rubber, PVC, modular, textile) with high wear resistance.
🔹 Modular design allows easy adjustment of conveyor length.
🔹 Adjustable incline angle (from 0° to 45°) to adapt to production conditions.
🔹 Can be equipped with protective covers and load control sensors.
🔹 Automatic control system integrates into production processes.

Types of KARMEL conveyors:

✔ Straight belt conveyors (for horizontal transport).
✔ Inclined conveyors (for loading materials to higher levels).
✔ Curved and vertical conveyors (for compact placement).
