Machine having a rotor which is mounted in a cantilevered fashion on a bearing and has a rotational axis along which a free, subsequently non-mounted rotor end runs starting from the bearing, the rotor end having a rotor end side which is spaced apart from a fixed rotor opposing side by a gap, and which, during operation of the machine when the rotor is rotating, is deflected with respect to the rotational axis as a result of imbalance of the free, non-mounted rotor end, or as a result of externally applied forces, wherein the rotor end side is curved or beveled so as to drop away at least in its end region towards its edge and in a direction towards the bearing.

An agitator ball mill including an in particular horizontal grinding container, which has a first end area having a grinding material inlet and a second end area having a grinding material outlet, and a method for operating an agitator ball mill. The agitator ball mill includes a shaft, which can be rotated in the grinding container or in the grinding chamber, respectively, by means of a drive unit and which is formed as agitator shaft at least in sections and which is equipped with agitator elements, as well as a separating device. The separating device includes a classifier rotor, which is arranged on the agitator shaft axially spaced apart from the grinding material outlet and has a rotatable rotor cage, as well as a screen unit, which is arranged within the rotor cage and which is fastened to the classifier rotor.

An open-ended grinding mill (1) includes a drum (2) including a cylindrical shell (3), wherein the longitudinal axis (4) of the drum is arranged in a substantially horizontal position in a use position of the grinding mill (1). The drum (2) includes a first end (5) at the feed end of the shell and a second end (6) at the discharge end of the shell. The grinding mill further includes a bearing (8) supporting the drum at the second end, and a support structure (9) to connect the drum (2) to the bearing (8). The support structure is configured to provide a wall external to the shell, whereby the shell and the support structure provide a double-wall structure separating the bearing from the inside of the drum.

A bearing block assembly for a plant-trimming machine having a rotatable perforated tumbler, a rotatable reel and a bed bar assembly. The bearing block assembly comprises an outer bearing plate having a bearing-receiving bore for holding a reel bearing to rotatably support an end of the reel, and an inner bearing plate affixed to the outer bearing plate. The inner bearing plate has a pocket for receiving the bearing-receiving bore of the outer bearing plate, the pocket having a tolerance permitting the bearing-receiving bore to be set at a selected position within the pocket. The bearing block assembly has connectors for affixing the outer bearing plate to the inner bearing plate. The bearing block assembly sets the positions of the reel, bed knife and tumbler correctly during assembly of the plant-trimming machine, reducing the time and skill required for maintenance.

A bearing arrangement of a horizontal grinding mill with a drum includes a first bearing device and a second bearing device, the drum being supported in rotation by the first and second bearing devices. The bearing arrangement further includes a load determiner that determines a load applied on the first bearing device and fill rate determiner that determines a fill rate of the drum during normal operation of the horizontal grinding mill from a first relationship determined during a calibration period. The first relationship correlates the fill rate of the drum to the determined load applied on the first bearing device.

An industrial powder making device having spiked hammer and blade arms. The device includes a powder making cylinder body, spiked hammer arms, a front oblique hammer, vertical hammers, a hammer arm, a detachable rack, a detachable rack inner bulge, spiked blade arms, a front oblique blade, high-hardness wear-resistant alloy sheets, a blade arm, a rotating shaft, a rotating shaft groove, a clamping piece, a feeding port, a discharging port, bearings, a rotating power module, a liquid nitrogen storage tank, a pipeline, a valve, nitrogen input holes, a nitrogen output hole, a fine particle collection device and a disc bevel discharging control device. An operating method is: crushing the ore by the spiked hammer arms, grinding the ore by the spiked blade arms, cooling with nitrogen, controlling equivalent input and output of the ore, and crushing and grinding the ore according to an established route, thereby realizing rapid powder making.
