Crushing of coal and calculation of size reduction efficiency.
Crushing efficiency has been defined in the literature from the power consumption point of view. But while operating a process plant, it is more important that the crushing efficiency is defined in terms of the requirement of subsequent process. The Process plant has been designed for coal size
Standard Bond Ball Mill Grindability Test Methodprocedure. However, ball coating and packing can increase the work input in dry grinding. the accompanying procedure and table can be used to shorten the calculations required with the new formula. the values of 44.5(p1) 0.23 are listed for each mesh size, and the values of (gbp) 0.82 can be found by interpolation from the table.

Quantifying the energy efficiency of fine grinding circuits
In this example, the OWi of the SAG mill was found to be 30% higher than the ball mill, thus suggesting that the SAG mill was less efficient than the ball mill. The apparent inefficiency of SAG mills when using Bond analysis is widely understood to be due to the difference in the slopes of the size distributions.

Ball Mills
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 energy efficiency of ball milling in comminution
In terms of this concept, the energy efficiency of the tumbling mill is as low as 1%, or less. For example, Lowrison (1974) reported that for a ball mill, the theoretical energy for size reduction (the free energy of the new surface produced during grinding) is 0.6% of the total energy supplied to the mill setup.
