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 ball mill slakers are much more expensive than paste or slurry slakers. They are available in sizes ranging from 1000lb/hr to 50 tons/hr. Figure 3 shows an attritor type vertical ball mill lime slaker. The ball mill slakers are equipped with an external classifier, which separates slurry from the oversized grit and impurities. The oversize ...

In the grinding material process at ball mills becomes necessary to calculate the bulk weigh of used grinding media. The bulk weigh of the grinding balls is necessary to understand the grinding balls mass in the cube, the grinding balls mass loaded into the mill, the prevention of mill overloading with grinding balls, etc. These data often used in operational management of …

Six different particle size ranges of the coal samples were obtained by using a laboratory-size ball mill for grinding and following with a classification by screening into < 38 μm, 38-63 μm, 63-75 μm, 75-90 μm, 90-180 μm and 180-250 μm. After that the samples were dried at 105 . o. C for 2 hrs before the CWS preparation.

The particles size distribution slope is not affected by the mill speed (see Graph 2) as the curves are mostly overlapping. Density These tests were done with a ∅0.82 x 1 m grate discharge mill with a 30 mm graded ball charge and a 30% filling degree. The mill discharge pulp density was increased from 68.8% to 75.9% solids.

slurry rheology for wet grinding applications is given in He et al. (2004). They suggest that optimization of slurry rheology for a mill may provide increased throughput, energy efficiency, and fineness of product.
