Abstract

1,167,899. Grinding cement. ALBRIGHT & WILSON (MFG.) Ltd. 24 Aug., 1967 [2 Sept., 1966], No. 39382/66. Heading B2A. [Also in Division Cl] To improve the time taken for dry grinding ores and cements a surface-active agent is added, e.g. in a ball or rod mill, or disc mill. The agent may be from the class of partial esters of phosphorus acids e.g. tertiary phosphate or phosphite ester added in the quantity 0.005% to 0.05% by weight based on the amount of material being ground. The general formula of the agent is:-(HO) b (O) a P(OR) 3-b wherein a=0 or 1, b has an average value between 0 and 2 and R is an alkyl group containing up to 7 carbon atoms or an aryl group.
