 — INTRODUCTION The energy consumption for grinding, according to Bond (1961), is deter- mined by the formula: / 10 10 (I) The work index is determined by grinding experiments carried out in a labo- ratory Bond ball mill. Based on the results of grinding experiments, numerical values of the work index Wi are calculated according to the …

 — The comminution efficiency of a HPGR is better than ball mills such that it consumes 30–50 % of the specific energy as compared to a ball mill. Four circuit configurations of HPGR can be used in grinding of raw materials, clinker and slag such as : Pre-grinding unit upstream of a ball mill. Hybrid grinding. Semifinish grinding

The grinding action in ball mills is primarily through impact and friction forces. In this article, ... Tumbling mills are generally less energy-efficient than ball mills due to the higher energy consumption required to lift the grinding media and material. In summary, both tumbling mills and ball mills are important pieces of equipment in the ...
