### Ball Mill Design/Power Calculation

Now we much select a Ball Mill that will draw this power. 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.

### Ball Mill Grinding Theory - Crushing Motion/Action Inside

Ball-mill power, 108 kw. In the first stage, 9.11 T. of minus 200-mesh material were produced per hour and 11.98 kw.-hr. were required for each ton of minus 200-mesh material produced. The classifier delivered 32 T. of sand per hour. The total feed to the mill was therefore 47.31 T. per hr. or 308 per cent, of the original feed.

### Industrial Ball Mills for Sale - 911metallurgist.com

The calculated liner and ball wear is expressed in kilograms per kilowatt-hour (kg/kWh), and when multiplied by the specific power (kWh/t), the wear rates are given in kilograms per ton of feed. The wear in dry ball mills is approximately one-tenth of that in wet ball mills because of the inhibition of corrosion.

### Equipment Sizing: Crusher or Grinding Mill

Equipment Sizing: Crusher or Grinding Mill. Since the selected crusher capacity must be in excess of 143 tons per hour, the next higher figure (159) is chosen. The 159 indicates a 548 crusher size with 1″ eccentric throw. With 1-in. eccentric throw, the motor hp allowed on the crusher is a maximum of 125.

### Calculating Power Draw when sizing Ball Mills - Grinding ...

I’m interested to know when sizing a new ball mill, as to why recirculating load has no effect on the power calculation, although it will have effect on volumetric capacity naturally. For instance a mill of 300tph with a 300% recirculating load would have 1200 tph going through effectively, but if
