Abstract: An edge mill for crushing materials for the manufacture of ceramic articles or the like, in which a cross head is rotatably mounted on a stationarily arranged track column which extends substantially vertically with regard to a substantially horizontally extending grinding track. The cross head is arranged in vertically spaced relationship to the grinding track and above the latter has mounted thereon driver cranks each of which has rotatably arranged thereon a roller-shaped grinding roller for rolling on the grinding track. The grinding rollers are drivingly connected to the driven member of a drive including a driving motor, especially a hydraulic motor. The driving motor is disposed between the grinding rollers on the track column and the member is directly connected to the cross head.

Abstract: A kneading device for clay and similar materials in which a frame has a horizontal shaft rotatable therein with at least one radially offset kneading member. The frame includes an upwardly concave reaction member concentric with the shaft. The reaction member has a circumferential portion which is perforated and which can be replaced by another such member having different perforations therein. The circumferential portions, or shells, are supported in the frame by respective curved rocker elements disposed therebeneath.
