Equipment Sizing: Crusher or Grinding Mill

UNTIL THE THIRD THEORY OF COMMINUTION of “Work Index” method of determining crushing and grinding mill size was introduced, there was no way of accurately figuring the most applicable, most economical size of crushing and grinding mill. Naturally, with little or no factual operating data correlated in useful form, it was easy enough, even for the most experienced, …


OMC have been assisting an African gold mine in optimising the comminution circuit, with a focus on operations practices and plant utilisation. The original circuit configuration consisted of a primary crusher followed by a SAG mill with a pebble crusher and a ball mill (SABC).

Comminution - Wikipedia

Comminution is the reduction of solid materials from one average particle size to a smaller average particle size, by crushing, grinding, cutting, vibrating, or other processes. In geology, it occurs naturally during faulting in the upper part of the Earths crust. In industry, it is an important unit operation in mineral processing, ceramics, electronics, and other fields, accomplished with ...

HPGR High Pressure Grinding Rolls

Use of HPGR eliminates tertiary crushing in a conventional grinding plant. In some cases, it may even eliminate the need for a secondary crushing stage. As an energy-saving alternative to the SAG mill, HPGR is particularly suited for the pregrinding of hard, highly siliceous gold ores.

Comminution Circuits for Gold Ore Processing - ScienceDirect

Although significant production of gold comes from both heap leaching (including run-of-mine and crush-for-leach) and milling operations, milling operations are present at 18 of the 20 largest producing gold operations in the world.

Comminution circuits for gold ore processing - ScienceDirect

For the vast majority of ounces of gold produced, comminution costs in the form of power, grinding media, and liners represent the single largest cost category of milling. Since, semi-autogenous grinding (SAG) ball-mill circuits represent the single largest type of gold milling comminution circuits, the chapter focuses on SAG.

Energy Consumption in Mining Comminution

3. Comminution and Mill Energy Requirements Comminution includes both crushing and grinding. Initially, ore is reduced in size by crushing rock to a size that makes it manageable. Crushing is accomplished by compression of the ore against rigid surfaces, or by impact against surfaces in a constrained motion path. Crushing is usually a dry ...
