The work index Wi can be determined from plant operations and from laboratory ball mill grindability, rod mill grindability, and impact crushing tests. The laboratory test results are used to check the efficiency of commercial operations and to compute the proper machine sizes for new installations.

The Bond Ball Mill Work Index is a measure of the resistance of the material to grinding in a ball mill. It can be used to determine the grinding power required for a given throughput of material under ball mill grinding conditions. It is a 'locked cycle' test conducted in closed circuit with a laboratory screen.

3 1. BALL MILL AIM: To determine the energy required for crushing the given feed and thus obtain the work index for the same. Also determine the reduction ration and critical speed of the mill. THEORY: The ball mill is classified as an intermediate and fine grinder where the action of the grinding is based on impact and attrition.

the 1- and 3-hour grinding periods. The mass ratio between the powder sample and the steel ball was 1:5. Also, 36 small steel balls with a diameter of 0.3 mm were ground for 5, 6, and 7 hours. The total weight of these balls was34.52 g. In this case, the mass ratio between the powder sample and the steel ball was 1:3.
