Re: Use Limestone for Cement Grinding Hello Tam I have seen values of >2% clay in concrete quoted as causing problems I believe there is a titration method for estimating clay contents using methyleneblue dye, but unfortunately I don't have any referencesJet mill grinding works by using multiple air jets or air streams to accelerate cement (or fly ash and limestone) particles from a very low velocity to the sonic velocity range As collisions occur between cement and/or supplementary cement particles, the cement and any supplementary cementitious materials are groundJet mill grinding of portland cement, limestone, and fly
Influence of grinding method and particle size
According to CEN, the use of CEM II limestone cements increased from 15 % in 1999 to 314 % in 2004 and became the single largest type of cement produced in Europe [ 5 ] In the conventional process of cement production, 30–80 kWh/t specific energy is consumed in cement grinding which equals 30 % of the total energy consumptionA typical raw mix consists of 7585% limestone, 1225% shale, the balance consisting of silica or quartzite and iron oxide Exact proportioning is dependent upon their chemical properties before and after calcining to cement clinker For good kiln practice the grind required is 8892% – 200 mesh for standard cement, 99%200 mesh for high earlyCement Grinding Mineral Processing & Metallurgy

Understanding Limestone in Cement| Concrete
The limestone acts as a seed crystal for the cement, better distributing the reaction products and increasing the reactivity of the cement As there is always unhydrated cement in the concrete, this change will have no real measurable effect on the use of fly ash The cement might have a reduced water demand, and the coarser cement gradationStep 4:Cement grinding and storage Clinker and gypsum for Ordinary Portland Cement (OPC) limestone for limestone cement, and slag for slag cement are all extracted from their respective hoppers and fed to the cement mills The ball mill grinds the feed to a fine powder in two chambers, namely the first and second chambersCement manufacturing process: Stepbystep guide CCE l
