Abstract: The invention relates to idler diagnosis systems on conveyors, comprising a rail system as a track for suitable running gears and the running gear, the rail system being formed from a closed profile or tube. The rail system comprises a multi-part track holder arranged on the belt frame, a fixing rod and a running rail, the track holder being suitable for accommodating the running rail at at least one end by insertion, thus creating a track without cross-section differences. The running gear has at least one two-roller system as a guide and drive system, and at least one chassis that accommodates and connects the two roller systems and has connection options for sensor-system carriers and/or energy control module. The guide system encloses the track so only one movement (forwards/backwards) along the track is provided. The drive system moves the chassis and all the connected systems with respect to the track.

Abstract: The present invention relates to a conveyor belt system with a circulating conveyor belt, in which a loadable conveyor belt segment rests on upper rolls and an unloaded conveyor belt segment rests on lower rolls, and in which an enclosure extending along the longitudinal axis of the conveyor belt system. The invention also relates to a system for monitoring the rolls in this conveyor belt system. A task of the invention is to propose a conveyor belt system in which the detection of defective rolls is facilitated. The task is solved by way of a conveyor belt system in which the enclosure features diagnostic windows on at least one side of the conveyor belt, such that the diagnostic windows are arranged at the level of the rolls of the conveyor belt and are designed for optical and/or acoustic monitoring of the bearings of the rolls, by being either transparent to diagnostic signals, or easily openable.

Abstract: The present invention relates to a crushing roll for a roll-type crusher has a shaft with at least one groove extending in the axial direction on its lateral surface, to receive formed elements. The formed elements serve to retain the crushing shells, for which purpose the formed elements form a form-interlockingly engaging combination with the groove in the shaft, in the radial direction. A “form-interlockingly engaging combination in the radial direction” is understood here to signify means of blocking of movement of the formed elements in the radial direction of the shaft. In this way, it is possible to anchor the crushing shells in the grooves by means of the formed elements.

The at least one load distribution element has at least two elastic, spatially separated individual elements, with at least one recess between the individual elements providing a spatial separation in the vertical direction.

Abstract: The present invention relates to a machine frame for a roll crusher that has two side walls and two end walls, where the mentioned end walls accommodate the storage of the rolls. The end walls are split horizontally in the area of the mounting of the rollers, and vertically between the mountings of the upper part. One advantage is that to remove a roller, removal of the respective upper end wall is sufficient. In a preferred embodiment of the invention, the adjacent upper parts of the end walls do not touch. An advantage of this is that tilting of the end wall upper parts among each other or in contact with the side walls is prevented during removal. Furthermore, the gap resulting from the distance between the front wall upper parts in the preferred embodiment would be sealed, with the advantage that no material and dust can exit.

Abstract: The present invention relates to a wear-resistant hard body that includes, at least partially, a high-strength, iron-based alloy, and preferably includes an external shell or sleeve made of another material.

Methods for producing the wear-resistant hard body or for producing hard bodies or side-wear protection elements for a roller of a roller press are also disclosed. A roller for a roller press that includes at least one wear-resistant hardy body as described herein is also disclosed.

Abstract: A machine frame (1) for a roll press. This machine frame has an axial frame (2) for absorbing axial forces developing due to the operation and at least two radial frames (3) for absorbing radial forces developing due to the operation.

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. The thrust bearing housing ring and the bearing cap are detachably connected into one unit, which is in turn fastened detachably to the thrust bearing cap, which is in turn detachably fastened to the bearing housing.

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: 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.
