Abstract: A transfer device is configured for transferring bulk material from a barge floating on a body of water into at least one receiving device. At least one lifting lock is provided by way of which the barge can be raised, while floating, to a tilting height above the surface of the body of water, and at least one tilting device is provided by way of which the barge can be tilted such that the bulk material is poured from the barge into the receiving device.

Abstract: A mobile crushing system with a sub-construction features at least one chassis and a superstructure featuring at least one receiving hopper, a crusher and a transport device. The superstructure features rigid bearings, and a hoisting device for raising and lowering the superstructure relative to the sub-construction and is provided between the superstructure and sub-construction. The superstructure is supported against the sub-construction by the hoisting device during traveling operation. The superstructure can be placed on the ground by the bearings by lowering the superstructure with the hoisting device during crushing operation in such a way that the bearings at least partially transmit the weight of the superstructure along with dynamic and static forces acting on the superstructure directly onto the ground.

Abstract: A conveyor belt system includes a conveyor belt running in longitudinal direction and support roller assemblies spaced apart along the conveyor belt and each having four support rollers distributed about the outer periphery of the conveyor belt. The conveyor belt is shaped into a tube having overlapping edges by an annular positioning of the support rollers. The conveyor belt extends, viewed in cross-section, from an edge lying on the inside at the overlap in a circumferential direction to an edge lying on the outside. The edges overlap at a last support roller, viewed in circumferential direction, and a distance between the last support roller, viewed in circumferential direction, and a center of gravity of a clear profile bounded by the support rollers is greater than a corresponding distance of the adjacently lying first support roller in circumferential direction.

Abstract: The invention relates to a vertical roller mill and a method for operating a vertical roller mill, wherein the grinding assemblies thereof, consisting of a grinding table and at least one grinding roller, interact such that material to be ground is comminuted in the grinding bed between the grinding table and the at least one grinding roller, wherein at least one grinding assembly is driven and at least one grinding assembly is pulled, and the pulled grinding assembly is braked in order to increase the flow of energy through the grinding bed between the grinding table and the at least one grinding roller.

Abstract: A conveyor belt system includes a conveyor belt extending in a conveying direction and support roller arrangements spaced apart from each other along the conveyor belt and each having six support rollers annularly distributed around the outer periphery of the conveyor belt, thereby imparting a tubular shape to the conveyor belt. The support roller arrangements each include a first group having support rollers and at least one support roller offset relative thereto in the conveying direction and peripheral direction. A distance determined along the conveying direction between the first group of support rollers and the at least one support roller of the same support roller arrangement offset relative thereto measures between 15% and 85% of a distance between the first group of the support roller arrangement and the first group of the next support roller arrangement in the conveying direction.

The edges overlap at a last support roller, viewed in circumferential direction, and a distance between the last support roller, viewed in circumferential direction, and a center of gravity of a clear profile bounded by the support rollers is greater than a corresponding distance of the adjacently lying first support roller in circumferential direction.

Abstract: A conveyor belt system includes a conveyor belt extending in a longitudinal direction and a plurality of support roller stations disposed at a distance from each other in the longitudinal direction and on which the conveyor belt is supported by support rollers. The conveyor belt is formed from a flexible base material and a plurality of unconnected traction devices which determine the tensile strength or rigidity of the conveyor belt and which extend in the longitudinal direction. As seen in the cross-section of the conveyor belt and with respect to a desired position on a central belt section supported on a support roller of the support roller station, the tensile strength or rigidity relative to the belt width is less than on laterally adjoining belt sections which are not supported in the desired position by a support roller. A conveyor belt is also provided.

Abstract: The roller mill according to the invention consists substantially of two grinding rollers which are driven in opposite directions and form between them a grinding gap for comminuting material to be ground, and a delivery chute via which the material to be ground is fed to the grinding gap. Furthermore, there is provided in the delivery chute a pressure sensor for measuring the static gas pressure, which pressure sensor is connected to a control or regulating device, which changes the circumferential speed of the grinding rollers in dependence on the measured static gas pressure. In the method according to the invention for operating the above roller mill, the static gas pressure in the delivery chute is measured and used to control or regulate the circumferential speed of the grinding rollers.

Abstract: The separation according to the invention of a material-laden hot gas stream substantially consists of the following method steps: the material-laden hot gas stream is separated in a first separator into a gas stream and a material stream, wherein the material stream contains a coarser and a finer fraction, and the material stream is then classified in a classifier with at least a proportion of the gas stream, the coarser fraction of the material stream being discharged, while the finer fraction is carried away together with the gas stream separately from the coarser fraction.
