Two drag chain conveyors.

Chain conveyors

Chain Conveyors are a competitive choice when bulk material is conveyed in an inclined angle. The main advantage of Chain Conveyors compared to other systems is the sealed frame structure — the conveyed material will not leak or spill out of the conveyor.


Modularly designed conveyors ensure easy and minor maintenance as well as extreme reliability in special conditions. Chain Conveyors are tailored according to the properties of the conveyed materials, capacity, and distance.
