A further measure, the Minnovex crusher index, Ci was also measured for use in the CEET program to determine SAG mill feed size Kosick and Bennett, 2001. The SPI values varied from 13.5 to 107 minutes with an average of 53 minutes. This variability, although apparently ...

A Crushinggrinding Plant Consists Of One Sag Mill

The feed rate to the Question A crushing-grinding plant consists of one SAG mill 4.42 m diameter X 2.0 m length, one ball mill 2.5 m diameter X 3.0 m length and a gyratory crusher. SAG mill operates in an open circuit with a single screen while the ball mill operates in a close circuit with 2 screens.

Grindin At The Mill Investigating Bottleneck In

A third ball mill takes a split of feed from each module to assist maintaining a target product size. Both modules are fed from the same primary crushing circuit via a Coarse Ore Stockpile COS which provides surge capacity. The grinding circuit is designed to produce a product size suitable for the downstream froth flotation process.
