Knoll offers two types of drag link conveyors. Both feature a three-phase geared motor and can be used as a stand-alone system or can be connected to additional systems. The continuous scraper moves the material to the conveyor bottom and then on to the discharge station.

The drag link conveyor type SF and type K are suitable for applications with short steel chips, needle chips (e.g. brass), cast-iron chips, cast iron dust and grinding wheel debris. The SF conveyor handles the wet processing while the K type conveyor is suitable for both wet and dry processing applications.
