摘要： The invention relates to a method for reconditioning a used grinding roller of a material bed roller mill having profile-members which are embedded, with a portion of the length thereof, in holes of the roller body and, with the remainder of the length thereof, project above the surface of the roller body. For the reconditioning operation, after the worn profile-members are removed, the worn surface of the roller body is turned, and a material layer is applied in a welding operation and is provided with holes for receiving new profile-members. Such a method allows particularly cost-effective reconditioning.

摘要： The invention relates to a milling roller of a high-pressure material bed roller mill, having profile-members which are embedded with a portion of the length thereof in holes of the roller body and, with the remainder of the length thereof, protrude above the surface of the roller body, with, when the milling roller is new, the holes having different depths and the profile-members having different lengths in differently loaded part-regions of the width of the roller body. Such a construction brings about a long service-life for the roller and cost-effective reconditioning after operational wear with a production operation which reduces costs.

摘要： In this method of comminution according to the invention, pre-comminuted ore material is subjected to material bed comminution in a material bed roll mill. In order to achieve optimal comminution even of very different ore materials with a high throughput the ore material is pre-comminuted in an autogenous mill, whereupon at least fractions of fine material are separated out of the pre-comminuted material before the rest of the material is further comminuted in the material bed comminution.

摘要： The invention relates to a roll mill with two rolls which are rotatably mounted in a machine frame and have an outer wear protection casing. In order to facilitate a particularly simple and rapid replacement of the wear protection casings on the rolls, both rolls are mounted only at one end in the machine frame.

摘要： The invention relates to a method of recovering precious metals from oxidic or refractory or semi-refractory ore material containing precious metal. This recovery of precious metal takes place with optimal comminution work and with more efficient and more reliable leaching also of non-oxidic ore material in such a way that the ore material is subjected to material bed comminution in the grinding gap between two rollers which are pressed against one another under high pressure and revolve in opposite directions and afterwards the comminuted ore material is preferably leached using a stirring movement in a container.

摘要： A roll mill has a fixed roll journalled in stationary fixed bearings and a floating roll journalled in movable bearings enabling the floating roll to be pressed against the fixed roll under high pressure. An adjustable spacing arrangement is provided between the two bearings to enable a gap of selected width to be formed between the rolls. The spacing arrangement includes a pair of shaft-like distance members received and guided in associated bores of the fixed bearings for movement therealong. Free ends of the distance members extend outward of their bores and engage the opposing floating bearings to adjust the positions of the rolls as they wear so as to maintain the selected gap width. The free ends are retractable into the bores to allow the bearings to abut one another and thereby optimize the wear life of the rolls.

摘要： In this method according to the invention for extracting metals, starting ore material is subjected to material bed comminution and then leached by the addition of leaching fluid. In order to be able to ensure an optimal yield of metals even in the case of greatly differing particles sizes of the comminuted ore material, the comminuted ore material is divided into oversize material and fine material, whereupon oversize material is delivered to a heap leaching and fine material to a tank leaching.
