摘要： Ore, rock or other solids are reduced to a predetermined aggregate size with minimum energy consumption and maximum efficiency and with a dramatically reduced wear factor on machinery compared to traditional ball mills and hammer mills. A relatively low speed impact rotor propells gravitating solids continuously on a zigzag path between moving rotor bars and opposing stationary impact plates in an array surrounding the impact rotor. Easily replaceable low carbon steel impact parts may be employed. The avoidance of sliding contact between solids and metal machinery parts minimizes wear. An optional positive air draft arrangement allows the collection of fines and dust outside of the impact chamber.

摘要： A Process and Apparatus for use in concentrating an aggregate mixture of particles, such as minerals and non-minerals wherein the mixture is introduced onto an inclined endless conveyor adjacent one edge of the incline and is advanced along or parallel to the incline while water is flowed across the inclined surface and the aggregate mixture during the advancement causing the lighter particles to flow with the water down and off of the inclined conveyor while the heavier particles cling to and are advanced with the conveyor surface to a collection area. The endless conveyor includes a plurality of slightly raised ribs on the upper surface which define recesses therebetween for catching and holding the heavier particles during advancement of the conveyor. The raised ribs can be formed into a number of various patterns. The endless conveyor also includes a plurality of horizontally spaced, downwardly projecting tits which form a reduced friction support surface and conveyor engagement drive means. The water is sprayed from a plurality of spaced jets which can be arranged for directing streams transversely across the conveyor or longitudinally along the conveyor.

摘要： A power transfer pipe, surrounded by an elastomeric, self lubricating seal assembly, transfers rotational power in one direction from a prime mover, at the upper end of the power transfer pipe, to a threadedly secured, hollow, drill pipe at the lower end, the seal assembly directs fluid from the sleeve into the drill pipe. A ratchet assembly at the upper end of the power transfer pipe, facilitates the disengagement of the power transfer pipe from the drill pipe.

摘要： A process is disclosed for separating a relatively more magnetic material from a relatively less magnetic material comprising passing the material being processed through a plurality of regions, each region having a relatively more magnetic segment and a relatively less magnetic segment, such that the plurality of regions are arranged so as to comprise alternating relatively more magnetic and relatively less magnetic segments, which regions are aligned at an angle other than 90.degree. in the plane of the surface of the regions to the direction of the resultant nonmagnetic forces such that the relatively more magnetic material has a tendency to travel at an angle to the direction of flow of the relatively less magnetic material thereby effecting the separation. Preferably each of the regions is aligned from 0.degree. to about 30.degree. with respect to each adjacent region.
摘要翻译：公开了一种用于从相对较小的磁性材料分离相对更多的磁性材料的方法，包括使被处理的材料通过多个区域，每个区域具有相对更多的磁性段和相对较小的磁性段，使得多个区域被布置成包括交替相对更多的磁性和相对较小的磁性段，所述区域在区域的表面的平面内与所得非磁力的方向以不同于90°的角度对准，使得相对更大的磁材料具有与相对较少的磁性材料的流动方向成一定角度的倾向，从而进行分离。优选地，每个区域相对于每个相邻区域对齐为0°至约30°。
