Ball Mill Drives Several types of ball mill drives can be furnished, made up of various combinations of gearing, motors and transmission equipment. The correct combination to be selected takes into consideration power requirements, gear ratings, floor space, interference from other plant equipment and motor characteristics.
Ball Mill Motor/Power Sizing Calculation Ball Mill Design/Sizing Calculator The power required to grind a material from a given feed size to a given product size can be estimated by using the following equation: where: W = power consumption expressed in kWh/short to (HPhr/short ton = kWh/short ton)

The details of the ball mill motor are as follows. Power = kW or HP and the speed is 343 rpm. Load calculations (prior to failure analysis) The ball mill can experience failure based on the maximum normal stress theory as the working loads acting in the ball mill is concentrated across the seam of the mill periphery.
The first large gearless ballmill in North America has been successfully installed at the Mississauga, Ontario, plant of the St. Lawrence Cement Company. The motor rating is 8750 hp (6500 kW) at r/min ( Hz). The electrical aspects considered of interest are discussed in the paper.
The energy consumption of the total grinding plant can be reduced by 2030 % for cement clinker and 3040 % for other raw materials. The overall grinding circuit efficiency and stability are improved. The maintenance cost of the ball mill is reduced as the lifetime of grinding media and partition grates is extended.

Do you need a quick estimation of a ball mill's capacity or a simple method to estimate how much can a ball mill of a given size (diameter/lenght) grind for tonnage a product P80 size? Use these 2 tables to get you close. No BWi Bond Work Index required here BUT be aware it is only a crude approximation for "most soft ores" from F80 1 cm ...
If your motor has an efficiency of and you measure 1000 kW at the motor input, then the motor output power you would measure (with a torque device) is 900 kW. This is why you are measuring more input power than the rated power; the rated "input" power would be 1500 HP divided by the motor efficiency.
Thus the power to drive the whole mill. = + = = 86 kW. From the published data, the measured power to the motor terminals is 103 kW, and so the power demand of 86 kW by the mill leads to a combined efficiency of motor and transmission of 83%, which is reasonable.
Fine grinding, to P80 sizes as low as 7 μm, is becoming increasingly important as mines treat ores with smaller liberation sizes. This grinding is typically done using stirred mills such as the Isamill or Stirred Media Detritor. While fine grinding consumes less energy than primary grinding, it can still account for a substantial part of a mill's energy budget. Overall energy use and media ...

Planetary ball mills are smaller than common ball mills and mainly used in laboratories for grinding sample material down to very small sizes. The main part of the ball mill mainly include feeding part, discharging part, a rotary part, a transmission part (reducer, small gear, motors, electrical control) and other parts.
SAG mill power vs. wear geometry maximizing kWhr/ton tons/hour in combination SAG mill liner changeout life/cycle vs. tons/kg consumed. Ball mill liner efficiency based on liner geometry and its influence on kWhours/ton, total tons/life cycle, and P80 transfer to cyclones.
Power as kW = E * (t/h dry solids) A ball mill can safely operate at 90% of its motor rated power, so choose a motor size like this: Motor size as kW = Power / You will not get a circulating load prediction from a Bond calculation. The assumption is that your secondary circuit is "efficient", whatever that might mean.

The poles of the gearless or synchronous motor (also called wraparound motor or ring motor) are directly installed on the pole flange of the mill shell, turning the mill body into the rotor. The stator is then wrapped around the mill. The gearless motor is fed by a cycloconverter which has a rated output frequency of around 5 Hz for the GMD drive.
