### Optimum choice of the make-up ball sizes for maximum

Fig. 11 shows the results of the grinding of a feed of various sizes at a size reduction ratio of 45 1 using a 1 m diameter mill. It can be seen that the optimum portion of the 50.8 mm balls decreases slightly as the value of N 1 increases for coarser feeds 13.8 mm and 9.5 mm. Size Reduction is mainly done through crushers and mills. Crushing and grinding are the two primary comminution processes. Crushing is normally carried out on the "run-of-m ine" ore.

A simple linear relationship between the E sc and the size reduction ratio was obtained in grinding studies using hammer mill for alfalfa chops Ghorbani et al 2010 and coriander seeds Shashidhar et al 2013 with R 2 095 and 093 respectively Those results reported that when size reduction ratio increased four times the energy

### IsaMill Technology Used in Effecient Grinding Circuits

Grinding media is retained in the mill without the need for screens which is why IsaMills™ can use fine media. At the end of the mill is a patented product separator consisting of a rotor and displacement body (refer to Figure 3). The close distance between the last disc and the rotor disc the ratio of the P98 to the P80 is around 2.5 Also the grinding efficiency of ball mill will reduce. If the steel balls are too small even the collision probability is relatively high but the energy of single steel ball is very small which cannot efficiently grind the ore particles also leading to the reduction of grinding efficiency.
