Cement Raw Mill First And Second Compartment

Optimization of an industrial scale open circuit three

1 Introduction Portland cement clinker is a black nodular hydraulic material It is made by burning in a rotary kiln (pyroprocessing), at least to sintering a precisely specified mixture of raw materials containing CaO, SiO 2, Al 2 O 3 and Fe 2 O 3 at temperatures of about 1400 °C Following the clinkering process in the kiln, clinker is cooled down in coolersmill for cement The mill shell is divided by a diaphragm mill shell is divided by a diaphragm Coarse grinding using big balls of up to 100 mm in diameter takes place in the first com partment The peripheral wear lining is designed as a lifting or the flow of material into the second compartment to be adjusted The transfer diaphragmIndustrial Solutions polysius ball millsHigh pressure grinding rolls (roller presses) are used in both cement raw materials (limestone, clay, shale etc) and cement grinding stages The energy consumption is 25–35 kW h/t and about 10 kW h/t when recycling of the material is usedA HPGR consumes 30–50% less specific energy as compared to a ball mill which indicates higher comminution efficiency for a HPGREffect of High Pressure Grinding Rolls (HPGR) pregrinding
