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.
The mill outlet temperature is maintained at a set value by introducing preheated primary air (PA) into the mill's inlet. The supply of the right quantity of PA is equally important so as to ensure sufficient heat input, which would be exchanged through direct mixing with the solid but pulverized fuel.
Ambient Temperature Deg C : -2 (min.) 48 (max.) The existing Ball mill system is envisaged to be used in combination with Roller Press and VSK separator in semi finish mode. The rejects from VSK separator will go to Roller press. The product from the VSK separator will go to mill via a solid flow meter.
