Application of Operating Work Indices in Autogenous

conventional grinding circuits (Bond 1961). Bond's third theory is presented in [1]. By rearranging the formula to [2], the operating work index (Wio) of an existing grinding circuit can be calculated, given known mill power draw, throughput, feed and product size distributions. kWh/t = Power applied per ton of feed to the grinding unit

Autogenous Grinding Semi Autogenous Grinding Circuits

Jul 20, 2017In conventional grinding, the size of product can be changed by changing media size, feed size, feed rate, classifier cut size, etc. The grinding circuit responds to these changes. In autogenous grinding, the ore "says" how it wants to be ground and the product size that it will produce, and does not change in response to the same factors.

Conventional Grinding

Conventional Grinding. Conventional grinding takes place in tumbling mills where the ore is introduced into a horizontal mill where the cylindrical body of the mill is turned by a motor, causing the mill charge of ore and grinding media to tumble. From: Wills'

Grinding Circuit

Grinding circuits are fed at a controlled rate from the stockpile or bins holding the crusher plant product. There may be a number of grinding circuits in parallel, each circuit taking a definite fraction of the feed. An example is the Highland Valley Cu/Mo plant with five parallel grinding lines (Chapter 12 ).
