Improving particle size distribution in cement production. 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.

There is a common misunderstanding that to make a finer cement you should reduce the mill ventilation to keep the cement in the mill longer. In fact, this simply leads to over-grinding and increased void filling, which reduces grinding efficiency and often leads to a wider particle side distribution, increased separator rejects and eventual reduced mill output.
