Abstract

A material processing plant consists of a first screw-type machine and a second screw-type machine: The screw-type machines are connected to each other by means of a pipe elbow. An elongation compensation device is disposed between the first screw-type machine and the pipe elbow. An expansion compensation device for thermal expansion of the second screw-type machine is disposed inside the last column of the first screw-type machine which is arranged upstream of the pipe elbow.
