Grinding Aids for Cement

11.05.2015a grinding mill which consumes 60-70% of the total electricity consumption of the cement plant[12]. A grinding mill (Ball Mill) is used to grind the cement clinker into fine cement powder. Grinding Aids are used to improve the grinding efficiency and reduce power consumption. This paper discusses the grinding aids mechanism and

In common Portland cement, particles having a size range from 3 to 35 μm are preferred for all the above-mentioned reasons. The common production indicator of optimal cement clinker grinding is the mass fraction of the size distribution passing through a 0.09-mm sieve. This should range from 90% to 97% of the distribution (Sauman, 1993).

The invention relates to the use of methyldiethanolamine as a grinding aid for cement, and in particular its use as a strength enhancing grinding aid for cement. The compressive strength may be enhanced by the methyldiethanolamine at both at an early stage (1and/or 3 days from the start of hydration) and at a late stage (7 and/or 28 days from the start of hydration).
