Tromp Curve Calculation
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.

For overflow ball mills, the charge should not exceed 45% of the mill volume . For grate discharge mills, the charge should occupy about 50% of the mill volume . Bond developed a relationship that can be used to determine the percent charge by volume as a function of the vertical height above the charge, He, and the radius of the mill, R, i.e.,

Transport equations : Mass and heat balances 9 mars 2017 The transport equations for mass and heat are obtained from conservation laws of mass, on one hand, and energy, on the other hand. We consider a volume V xed in space and bounded by a surface @V = Sand we write the balance between the change of mass or energy within V and the net

Frictional heat due to passage of feed through the pellet mill adds 2 or 3 degrees of temperature. The moisture, temperature, and time involved combine to impart a sticky surface to starch-containing ingredients which, when subsequently dried, improved pellet hardness and water stability.

The Ball Mills are on a schedule of 4-monthly overhaul. The main job is the repair or replacement of the lifters and liners, but other work is carried out on the mill to ensure its reliable operation over the following 4 months. In addition, preventive maintenance is carried out on other units in the stream (e.g. the conveyors).
