Relationships between comminution J energy and product

property of an ore (kWh/t) for grinding from the product of the final stage of crushing to a P80 of 750 lm (coarse particles) the index is labelled Mia and for size reduction from 750 m to the final product P80 normally reached by conven-tional ball mills (fine particles) it is labelled Mib W is the specific comminution energy at pinion (kWh/t) x 2 is the 80% passing size for the product

Flexible milling and grinding solutions that last

For the mining industry our semi-autogenous (SAG) grinding mill uses a minimal ball charge in the range of 6-15 percent It is primarily used in the gold copper and platinum industries as well as in the lead zinc silver and nickel industries Autogenous (AG) grinding mills involve no grinding media as the ore itself acts as the grinding media

Arrastra

An arrastra (or arastra) is a primitive mill for grinding and pulverizing (typically) gold or silver ore Its simplest form is two or more flat-bottomed drag stones placed in a circular pit paved with flat stones and connected to a center post by a long arm With a horse mule or human providing power at the other end of the arm the stones were dragged slowly around in a circle crushing the
