SAG Mill Grinding Circuit Design 911metallurgist

2016-6-6  Many large mills around the world (Esperanza with a 12.8 m mill. Cadia and Collahuasi with 12.2-m mills, and Antamina. Escondida # IV. PT Freeport Indonesia, and others with 11.6-m mills) have installed SAG mills of 20 MW. Gearless drives (wrap-around motors) are typically used for large mills, with mills

Ball Mill an overview ScienceDirect Topics

3.5.2.2 Ball Mills. The ball mill accepts the SAG or AG mill product. Ball mills give a controlled final grind and produce flotation feed of a uniform size. Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds.

1994-2-1  SAG mills, on the other hand, rarely approach the efficiency of a ball mill. Breakage mechanisms are not nearly so well defined, and while it is possible to influence breakage rates in the mill by changes in mill speed, ball load, and feed size distribution, manipulation of these variables will often fail to produce a power efficient circuit

The Selection and Design of Mill Liners MillTraj

Mines (WA) 36ft SAG mill the number of Outer Head Liners was reduced from 36 to 18 pieces and in doing so reduced the time to replace them by 9 hours at a cost downtime saving of about U$25,000 per hour. In this case the liners sections are 3.5 t each. For smaller mills the liners have to be handled and installed manually, so smaller blocks with
