Crushing, grinding, and polishing machine workers operate the equipment used to process materials such as coal, glass, grain, and rubber. These machine operators review work orders and load specified amounts of materials or mixtures into machines. Workers sometimes break materials down to size using picks or other hand tools, to ensure ...
While both involve reducing the size of materials, they are actually two distinct processes. Crushing involves applying a force to materials to break them apart, often using compression or impact. Grinding, on the other hand, involves reducing the size of materials using friction, shear, or impact between two surfaces.
When making comparisons of the efficiencies of different grinding and crushing machines it is desirable to be able to estimate the work actually done in crushing the ore from a given size of feed to a given size of product, the screen analysis of both feed and product being determined. Messrs. Klug and Taylor, in a paper on this subject, …
