### Ball Millan overview ScienceDirect Topics

Ball mills give a controlled final grind and produce flotation feed of a uniform size. Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.- ore and 25 steel. 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.

### How can one select ball size in ball milling and how much

More balls with small size results in fine powder. As a thumb rule powder to be milled should be taken as 25 of total ball weight. If the quantity of charge is very less then milling balls will The basic parameters used in ball mill design (power calculations) rod mill or any tumbling mill sizing are material to be ground characteristics Bond Work Index bulk density specific density desired mill tonnage capacity DTPH operating solids or pulp density feed size as F80 and maximum chunk size product size as P80 and maximum and finally the type of circuit open/closed you are designing for.

### Ball Mill Design/Power Calculation

Dec 12 2016 · 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 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. Bearing. Since the power of the autogenous tumbling mill is relatively small it is appropriate to choose dynamic and static pressure bearing. The ball bearing liner is made of lead-based bearing alloy and the
