Trough chain conveyors
for horizontal transport or transport on a slight upward incline
Chain conveyors transport floury, grainy and lumpy bulk materials horizontally or on a slight upward incline. Chain conveyors can also be used as intake chain conveyors and for silo discharge.
Starting with our standard modular-system we adapt the chain conveyor to the product characteristics, the installation situation and the process requirements.

Trough chain conveyorBasic design
- Motor mounting platform with geared motor and flexible coupling
- Tensioning station and driving station, outside varnished and inside untreated, or hot-dip galvanised
- Troughs of strip-galvanised steel or outside varnished and inside untreated
- Return rollers made of plastic (standard for KF240, KF315 and KF350) or ball-bearing return rollers made of steel (standard for KF440 and KF560)
- Wear rails made of highly wear-resistant steel, e.g. Hardox, guide rail made of St52. With plastic bottom no wear rail
- Conveyor chain according to DIN 8165 with single bent-back plates
