This study evaluates the effect of using high pressure grinding rolls (HPGR) in new comminution circuit designs in comparison to conventional comminution devices such as SAG and ball mills, in terms of energy efficiency. The total energy to achieve similar product sizes was measured directly in the process by using a new digital energy meter. The difference between the ...

In contrast to laboratory-scale testing for ball mills and AG/SAG mills, test work results for stirred mills can be used for sizing full-size equipment with a scale-up factor close to one. Larson et al .[ 19, 20 ] found a scale-up factor for the Isamill of exactly 1, while Gao et al .[ 8 ] imply that the scale-up factor for SMDs is 1.25.

Generally ball mills are utilized after an initial material crushing or grinding has occurred. Thus, a disadvantage of the ball mill is that the feed size must already be small. Table 2 outlines some typical ball diameters found in ball mills dependent on the staging or purpose of the mill. Table 1 - Ball mill feed and product sizes (Callow ...

3.5.2.2 Ball Mills The ball mill accepts the SAG or AG mill product. 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.

A ball mill is a type of grinder used to grind or blend materials for use in mineral dressing processes, paints, pyrotechnics, ceramics, and selective laser sintering.It works on the principle of impact and attrition: size reduction is done by impact as the balls drop from near the top of the shell. A ball mill consists of a hollow cylindrical shell rotating about its axis. T

The operation of AG/SAG mills, therefore, involves the use of cheaper grinding media as a replacement for expensive steel balls and rods which greatly affect the wear on liners. They are, therefore, less expensive to operate. It is necessary that the ore should provide a sufficient amount of lumps that would last for a reasonable time.

It was decided to replace the SAG and ball mill in the comminution circuit as proposed in the 2019 DFS with a three stage crushing plant and ball mill. This was done to reduce the risk and increase the security of the operation by minimising the possibility of a long shutdown of the plant caused by a SAG mill equipment

The point where the mill becomes a centrifuge is called the "Critical Speed", and ball mills usually operate at 65% to 75% of the critical speed. Ball Mills are generally used to grind material 1/4 inch and finer, down to the particle size of 20 to 75 microns. To achieve a reasonable efficiency with ball mills, they must be operated in a closed ...
