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.
摘要翻译：用于浓缩诸如矿物质和非矿物质的颗粒的聚集混合物的方法和装置，其中将混合物引入到与倾斜的一个边缘相邻的倾斜环形输送机上，并且在水流动的同时沿着或平行于斜面前进在倾斜的表面和聚集体混合物的前进过程中，使较轻的颗粒随着水从倾斜的输送机向下流动而流动，同时较重的颗粒粘附并且与输送机表面一起前进到收集区域。环形输送机包括在上表面上的多个略微凸起的肋条，其间形成有用于在输送机的前进过程中捕获和保持较重颗粒的凹部。升高的肋可以形成多种各种图案。环形输送机还包括多个水平间隔开的向下突出的奶嘴，其形成减少的摩擦支撑表面和输送机接合驱动装置。水从多个间隔喷嘴喷射，喷射器可以布置成横向地横向输送机流动，或者沿输送机纵向引导。
