Jun 19, 2015· The ball mill motor power requirement calculated above as 1400 HP is the power that must be applied at the mill drive in order to grind the tonnage of feed from one size distribution. The following shows how the size or select the matching mill required to draw this power is calculated from known tables ‘the old fashion way’.

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.

Nov 26, 2019· The calculation shows that the crushing ratio can reach 3000 ~ 4000, while the ball mill’s crushing ratio is smaller. The feed size is usually between 20-30mm and the product size is 0-3mm. Feed.,And because the ball mill feed grain size is larger, ball mill feeding groove must have a larger slope and height, so that feed smooth.
