Jan 14, 2004 If open and closed circuit experiments are compared in terms of specific energies of the products of equivalent Blaine surface area, closed circuit experiments uses more energy than the open ones. Closed circuit experiments resulted in a Blaine area of 4000 cm 2 /g at a specific energy consumption of 100 kW h/t. However, the same surface area can be achieved at 55 kW h/t for open

The Closed-circuit Grinding System of Ball Mill in Cement Plant. Years of cement production practice shows that cement particle gradation should be distributed continuously within a certain size range. Generally speaking, the cement particles smaller than 32 μm are beneficial to reduce bleeding and early strength, but as the size of particles gets smaller, although the hydration activity increases, the

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. The drum is generally divided into two or three chambers, with different size grinding media
