Heat balance calculators. The calculation of the thermical balance of the ball mill is now proposed according 2 methods: - The first method, we know the ventilation of the mill + the cement temperature and we want to calculate the water quantity we need to inject in order to get the temperature at mill outlet we would like to have. - The second method, we know the ventilation inside the mill + the quantity of water injected and we calculate the temperature of the cement at mill
The ball mill is in a closed circuit loop with sump and sieve bend. The sump has a feed of 60.1% solids,water addition to sump is 100 cubic meters per hr and outflow from sump constitutes 49.1 % solids.This feeds onto a sieve band which has an under-screen flow of 42.9% solids
8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 20–40% water by weight

Ball Mill Operation. Ball mills ride on steel tires or supported on both ends by trunnions. Girth gears bolted to the shell drive the mill through a pinion shaft from a prime mover drive. The prime movers are usually synchronized motors. During rotation, a portion of the charge is lifted along the inside perimeter
mixer mill and Takacs and McHenry reported milling ball temperatures of 66 C[12, 13]. Comparably higher tem-peratures can be reached in planetary ball mills (PBMs), where temperatures from 60 to 600 C can be measured, depending on the type of PBM, the grinding stock, the grinding material and the ﬁlling degree [5
