FLASH CALCINERS A focus on flash calcining

to a calciner in a clinker kiln. • overall thermal energy consumption is lower than in a rotary kiln system due to less area of hot surfaces exposed to ambient and better heat recovery. • overall electrical consumption is similar or lower than in a rotary kiln due to different requirements in grinding energy and the absence of the kiln


Cement Grinding - Mineral Processing & Metallurgy

A typical raw mix consists of 75-85% limestone, 12-25% 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 88-92% – 200 mesh for standard cement, 99%-200 mesh for high early.
