Drag chain conveyors have an endless chain with carriers (cross ribs) which runs in a closed trough. This makes them suitable for transporting bulk materials. Depending on the design of the carriers and trough, material can be conveyed horizontally, on an incline or vertically. Bends 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.
The KKF 400/500/1K-U/TS drag chain conveyor transports the material in the lower belt and is an ingenious combination of a drag chain conveyor and screw conveyor. It is mainly used to dispose of material downstream of the shredder, or as a discharge conveyor downstream of a silo discharge. The screw shaft is driven via the conveyor chain. A separate drive is not required. Trough widths of 400 mm and 500 mm and screw diameters of 200 mm, 250 mm and 300 mm are available with this drag chain conveyor.
Chain conveyors with endless chains with feed dogs in closed troughs are suitable for the transport of bulky material.
This version of Vecoplan-chain conveyors transports the material in the lower run by means of a centered conveying chain with 11.2 t breaking load. The chain runs in the return on a low-wear chain guide rail that is entirely covered in the feeding area so that no material can get into the chain.
By use of upper and lower elbows the course of chain conveyors is almost on choice. Motorical or pneumatical slides allow additional user-defi ned discharge positions.
