Cement Mill outlet blaine Page 1 of 1 Cement Mill outlet blaine. In my cement plant, the mill feed is the tailings from the separator. The average surface area of the mill feed is 85 m2/kg. If the target surface area of the cement I produce is 360 m2/kg, what should be my mill outlet surface area? Reply. Know the answer to this question?

On the other hand for fine grinding (> 3,000 blaine), the main factors become: 1) alite size, as before. 2) C2S content, as before. 3) grinding aid. Cost €/t, usage 150400 g/t. As the cement particle gets smaller the pores disappear and no longer become a factor.

Cement manufacturing brief description of a cement mill. Cement clinker is usually ground using a ball mill. This is essentially a large rotating drum containing grinding media normally steel balls. As the drum rotates, the motion of the balls crushes the clinker. The drum rotates approximately once every couple of seconds.

36 Cement Mill. The ball charge tendency in the 1st compartment is to use the coarser of the gradings available. When producing high Blaine Cement it is the objective to use less tonnage. Achieve nearer 89 kWh/t at the target mill output instead to go for a more fine ball charge (??) Standard design is adapted for 3200 cm²/g.

The cement grinding mill circuit loaded approximately 95% through clinker raw materials and rest of the feeding material is performing properties enhancer [16], [17]. In grinding process, the quality of cement in terms of fineness was measured by using Blaine's surface area and particle size distribution analysis [18] .
