Improving particle size distribution in cement

Enhancing cement grinding efficiency is beneficial for numerous reasons: Lower energy costs. An improvement in grinding efficiency means increased fineness at constant kWh/t or, more typically, lower kWh/t for constant fineness. Increased mill production. Higher grinding efficiency delivers the same fineness at higher output.
