Cement Manufacturing Process

Aug 30, 2012· Cement Manufacturing Process Phase V: Cooling and Final Grinding. After passing out from the kiln, clinkers are cooled by mean of forced air. Clinker released the absorb heat and cool down to lower temperature. Released heat by clinker is reused by recirculating it back to the kiln. This too saves energy.

Energy consideration in cement grinding

typically generates ~ 25 kcal of heat per kg cement ground o Mill temperature could rise to 140 ˚C and causes gypsum to dehydrate & produces "false set" in cement, as well as "media coating" which impairs grinding efficiency o typically, ~ 0.8 m³ of cooling air is required to remove the heat Energy consideration in cement grinding

Curling of Concrete Slabs — What, why, & how? – Nevada

Curling is the distortion of a slab into a curved shape by upward or downward bending of the edges. This occurs primarily due to differences in moisture and/or temperature between the top and bottom surfaces of a concrete slab. The distortion can lift the edges or the middle of the slab from the base, leaving an unsupported portion.
