However, particle size distribution is again a problem, and roll presses are now increasingly popular as a "pre-grind" process, with the cement finished in a single chamber ball mill This gives good cement performance, and reduces energy consumption by 20-40% compared with a standard ball mill system Capacity of cement mills

Apr 15, 2008· Measuring and controlling the particle size distribution of cement is important both in order to achieve the desired product performance and to control manufacturing costs Historic techniques of sieve and air permeability are still in use, but laser diffraction is becoming a more popular method to determine the particle size distribution of .

A ball diameter that grabs the particle must exceed the particle by 25 times to achieve this semi-self locking taper One can argue the f50 is a more realistic value since balls wear and the average ball size might be closer to half the maximum Then the multiple would be closer to 13 times the maximum particle size fed to the ball mill
