Chain Conveyor

Chain conveyor are continuous conveyors and are suited for the conveyance of bulk products of all kind up to small-sized products and sludges. The advantages are its excellent temperature resistance (up to 800°C), the low conveying velocities, particularly in case of abrasive bulk material, and the robust and dustproof design. There is a wide range of possible applications and different configurations. At present, more than 300 devices are used by more than 70 customers worldwide.

Power Plant Costa Rica

In this diesel-fired power plant, exhaust air is cleaned by means of two electric filters. Respectively two trough chain conveyors per filter serve for evacuating the ash. For each line, a collecting trough chain conveyor is provided receiving the ash.
