Based on the energy expended in the ball mill, the production rate of new product size material (tonnes/h) equals the amount produced per unit of energy applied (tonnes/kwh) times the rate at which energy is applied (kwh/h). The rate at which energy is applied is the power draw of the ball mill. If we then define the production per unit, of ...

A SAG mill, or semi-autogenous grinding mill, is a type of machine used in mining and mineral processing operations. It uses the crushing and grinding action of rocks to reduce materials such as copper ore into smaller pieces for further processing. Unlike traditional mills that rely on steel balls or other media to break down materials, SAG ...

One obvious reason is that impact energies in laboratory mills are negligible compared to those in industrial mills. For example, Dodd et al. (1985) have estimated that an increase in ball kinetic energy from 1.4 J for a 0.025 m ball in a 0.20 m ball mill to 350 J for a 0.127 m ball in an 8.5 m ball mill.

High temperature of the ball mill will affact the efficiency. 3 For every 1% increase in moisture, the output of the ball mill will be reduced by 8% -10%. 4 when the moisture is greater than 5%, the ball mill will be unable to perform the grinding operation. 5. The bearing of the ball mill is overheated and the motor is overloaded.

The working principles of a SAG mill involve the crushing and grinding process of the ore particles. As the mill rotates, the ore and grinding media are lifted and dropped, causing the ore particles to be crushed and ground. The impact between the ore and grinding media results in the reduction of the ore size.

SAG mills are often used in conjunction with a ball mill or pebble mill to achieve the desired grind size. SAG mills are primarily used in the mining industry, particularly in the processing of gold, copper, and platinum group metals. On the other hand, AG mills, or Autogenous Grinding mills, use only the ore itself as grinding media.
