The KKF 670/820/970/1150-2K- drag chain conveyor transports material in the upper belt and can be used as a discharge conveyor downstream of a silo discharge. It features two external conveyor chains that run on chain slide rails. Covers fitted over the chains in the feed area protect against the ingress of material. The conveyor chains have a breaking load of 11,2 t. Trough widths of 670 mm, 820 mm, 970 mm and 1,150 mm are available.
Drag chain conveyors have an endless chain with feed dogs (cross ribs) which runs in a closed trough. This makes them suitable for transporting bulk materials. Depending on the design of the feed dogs and trough, material can be conveyed horizontally, on an incline or vertically. Bows can be installed allowing different conveyor sections to be combined.This makes them particularly suitable for use as discharge or distribution conveyors. Material can be conveyed in the lower run as well as the upper run.
