Abstract: A two-roller roll press, with a machine frame, has two rollers, which have shaft journals at respective axial ends of the rollers for mounting in a bearing construction. At least one of the rollers is mounted at one or both shaft journals in a thrust bearing construction. The thrust bearing construction has a thrust bearing, a thrust bearing housing ring, an outer thrust bearing cap and a bearing cap. The thrust bearing is shrunk onto a shaft journal.

Abstract: The transmission holder according to the invention for a roller press has a two-part structure with a transmission part which is connected to the transmission and a separate torque supporting part which is to be connected to the machine base frame or foundation. Transmission and torque supporting part of the transmission holder can be detachably connected to one another, preferably by means of a screw or bolt connection. In one embodiment this connection has two screws or bolts. Advantageously the dismantling or assembly of the rollers can thus be accomplished significantly more simply than according to the prior art since merely the screw or bolt connection between transmission and transmission holder of the transmission holder must be released. Advantageously significantly fewer screws/bolts need to be released for dismantling the transmission which in addition are more readily accessible and have a significantly greater distance from one another than according to the prior art.

Abstract: A closing element for a machine frame of a rolling press, that sits on the end of a frame element as a hasp. The closing element includes an element enabling a pendular motion on the frame element. In this way, floating mounting of the closing element is achieved. This enables a very fast dismounting that facilitates the replacement of the rolls, and leads to an optimum arrangement of the closing elements on corresponding end pieces of the machine frame.

Abstract: A process for producing a casing for a roller press for subjecting particulate matter to be ground to high pressure treatment, the casing having a profiling defined by profile comb, wherein the process includes the steps of casting a cylindrical hollow body and introducing axial longitudinal grooves onto the surface of the cylindrical hollow body. The material for casting is of a particular composition, where that composition includes, among other components, between 0.0012% and 0.0027%, by weight, of phosphorus (P).

Abstract: A method for regulating the roll gap pressure of a roller press and a corresponding roller press. The roll gap pressure is regulated dependent on at least one oscillating movement that is measured on the roller press. This has the advantage that the roller press can always be operated at the maximum roller press efficiency without the roller press reaching the overload range.

Abstract: The wear-resistant hard body according to the invention consists, at least partially, of a high-strength, iron-based alloy (IFW), and preferably comprises an external shell or sleeve made of another material. Roller press rollers usually have a bandage, often referred to as a roller body, in which the hard bodies are inserted as grid armoring. Particularly preferably, the hard body has a trilaterally closed, external shell. Advantageously, the hard body thus hardly needs any processing to ensure that it fits into the hole in the bandage, as the shell already does. Thus, a defined fit between the bandage and the shelled hard body is made possible. The hard bodies according to the invention with a shell or a sleeve are also referred to as bimetallic studs. Particularly preferably, the wear-resistant hard bodies furthermore have a circular cylindrical shape. Here, the closed front end of the shell, which in the installed state faces the center of the roller, is preferably shaped in a rounded fashion.

Abstract: The present invention relates to side wear protection for rollers of a roller press and to a roller of a roller press comprising this side wear protection. In one embodiment, the side wear protection according to the present invention and for the roller of a roller press comprises several side wear protection element surrounding the roller edge. According to the present invention, the side wear protection elements have a base body comprising an elastic, ductile material. Furthermore, the base body has a threaded bolt on the side of the base body directed toward the roller axis.

Abstract: The present invention relates to a radial frame as a radial force-receiving element of a machine frame of a two-roller press with a fixed roller and a loose roller, comprising two opposing side parts, each with a belt system with belts and box frame as a frame top part and as a frame bottom part, with vertical frame end pieces inserted left and right into the frame upper part and frame lower part which frame end pieces are constructed to be detachably fixed on the fixed roller side as replaceable end pieces and on the loose roller side with the same construction. The vertical frame end pieces are connected at their upper end to a rotary articulation and the particular double belts running in parallel comprise welded head connections at their ends on which head connections the vertical frame end pieces (vertical crossbeams) are supported.
