Ag mill pebble mill. two stage aggrinding with the primary mill in open circuit and the secondary pebble mill in closed circuit. the pebbles screened out from the primary mill or recirculated to the primary mill based on size.

Addition Of Pebbles To A Ballmill To Improve Grinding

It may be concluded that composite grinding is not sensitive to pebble size and a wide range of pebble sizes can be used, with the largest pebble size being much larger than the top ball size. this is an important practical consideration, as a larger tonnage of rounded pebbles will be available from a primary sagag mill discharge, than the.

Grinding Mills: How They Work | Neumann Machinery

The primary function of a ball mill is to reduce larger particles to fine particles. in the base metals mining industry this particle size reduction (psd) allows downstream processes to more fully access the metal content embedded in the ore. balls or rods are placed inside the rotating drum which when combine with ore will break up the larger.

The operation was commissioned in 2012, and consists of a partial secondary crushing circuit followed by an ag – pebble grinding circuit with two partially closedcircuit ag mills and a single closedcircuit pebble mill. the ore is variable and can range from average competency to extreme.
