A survey of 40 industrial mills in Australia found that the maximum ball mill diameter in use was metres and length metres [1]. Autogenous mills range up to 12 metres in diameter. The lengthtodiameter ratios indicated in Table for ball mills are for normal use, but for primary grinding the ratio could vary between 1:1 and :1 ...
Based on his work, this formula can be derived for ball diameter sizing and selection: Dm <= 6 (log dk) * d^ where D m = the diameter of the singlesized balls in = the diameter of the largest chunks of ore in the mill feed in mm. dk = the P90 or fineness of the finished product in microns (um)with this the finished product is ...
Typically R = 8. Rod Mill Charge: Typically 45% of internal volume; 35% 65% range. Bed porosity typically 40%. Height of bed measured in the same way as ball mills. Bulk density of rods = tons/m3. In wet grinding, the solids concentration 1s typically 60% 75% by mass. A rod in situ and a cutaway of a rod mill interior.
where d 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.

The Ball Mill is designed to grind materials by turning the cylindrical shell with grinding medium ( steel balls, cylpeb, and pebbles) put in the shell, and has a simple structure and ease of handling. Furthermore, The Ball Mill of a large capacity has been available to a very extensive range of applications in both dry and wet processing.
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 times the shell diameter (Figure ). The feed can be dry, with less than 3% moisture to minimize ball coating, or slurry containing 2040% water by weight.
ball mill capacity 140 th; Ball Mills Mineral Processing Metallurgy. Feb 13, 2017 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 ...

If a ball mill uses little or no water during grinding, it is a 'dry' mill. If a ball mill uses water during grinding, it is a 'wet' mill. A typical ball mill will have a drum length that is 1 or times the drum diameter. Ball mills with a drum length to diameter ratio greater than are referred to as tube mills.
