A ball mill is a type of grinder used to grind, blend and sometimes for mixing of materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotati

where d b.max is the maximum size of feed (mm); σ is compression strength (MPa); E is modulus of elasticity (MPa); ρb is density of material of balls (kg/m 3); D is inner diameter of the mill body (m).. Generally, a maximum allowed ball size is situated in the range from D /18 to D/24.. The degree of filling the mill with balls also influences productivity of the mill and milling efficiency.
Jan 15, 2001· Grinding was carried out in the laboratory ball mill described in Table 1, at a low ball load of 20% of the mill volume filled with the ball bed and a low powder load corresponding to a formal interstitial filling of void spaces of the ball bed of U=0.5. These conditions were chosen since it is known that they give first order grinding kinetics for normal grinding, both dry and wet.

This type of mills is used to produce products of coarse particles of less than 1 to 5 mm in diameter. You are able to run these mills with elimination of troubles such as sticking or bridging as not only pre-mill to the dry-grinding ball mill but also fine grinding mill for wet coke and ores, and others.
Ball Mills Mineral ProcessingMetallurgy. 2020-5-18 Working PrincipleOperation. The apparent difference in capacities between grinding mills (listed as being the same size) is due to the fact that there is no uniform method of designating the size of a mill, for example: a 5′ x 5′ Ball Mill has a working diameter of 5′ inside the liners and has 20 per cent more capacity than all other ...
