It has been shown that the comminution process accounts for a large portion of operating costs and is the main consumer of energy for most mining and mineral processing operations. In addition to this the throughput of the comminution circuit is a major driver for .
The Total Comminution Specific Energy window at the top of the page gives the specific energy for the entire circuit. It is made up of the sum of any crusher/HPGR net specific energies plus the tumbling mill circuit specific energy at pinion. The associated 95% confidence levels are also shown
The SMC and Bond ball work index experiments as well as the Morrell model indicated that the order of the specific energy consumption of comminution was "Jaw crusher + HPGR mill + ball mill" < "Jaw crusher + ball mill"< "SAG mill + ball mill". Next Article in Journal.

A specific energybased size reduction model for batch grinding ball mills was reported in a previous paper (Shi and Xie, 2015). A discharge function modified from the Whiten classification efficiency equation has been incorporated in the size reduction model to extend its applications from batch grinding to continuous operation.
particle breakage versus energy data was converted into breakage rates with the impact energy spectra of the grinding mill. The proof of the modeling concepts is shown for a 90 cm laboratory scale ball mill. The material used in the study was limestone. In the batch mill, approximately a .
BM = Ball mill specific energy from T 80 mm to final product P 80, using Bond''s Law, (kWh/t) W T = Total grinding mill circuit specific energy (kWh/t) Note that K BM is the composite of EF3, EF4 and EF5 factors for ball milling (Rowland, 1982). Morrell and SMCC Morrell (2004) developed a methodology for predicting specific energy with
APPENDIX A. USE OF THE Mia, Mib, Mih, Mic IN PREDICTING COMMINUTION CIRCUIT SPECIFIC ENERGY A 1 INTRODUCTION The following technical note describes the recently extended use of the SMC Test® to include crushers and HPGRs in determining the overall specific energy demand of
For comminution of finer particle size ranges (20mm > P 80 > 30 μm) machines like the ball mill, vertical roller mill, hammer mill, roller press or high compression roller mill, vibration mill, jet mill and others are used. For yet finer grind sizes (sometimes referred to as "ultrafine grinding"), specialist mills such as the IsaMill are used.
A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many are many different types of mills and many types of materials processed in them. Historically mills were powered by hand (, via a hand crank), working animal (, horse mill), wind or water ().
