Abstract
Thick matter and solids are conveyed together and substantially continuously through a conveyor pipeline. The thick matter is forced by a conveyor piston driven by a piston pump from a feed container into a conveyer cylinder. A forward face of the piston has a cutting crown with a cutting edge cooperating with an annular cutting ring to cut off solids projecting beyond an inlet in the conveyer pipeline.
