A Bond Ball Mill Work Index test is a standard test for determining the ball mill work index of a sample of ore. It was developed by Fred Bond in 1952 and modified in 1961 (JKMRC CO., 2006). This index is widely used in the mineral industry for comparing the resistance of different materials to ball milling, for estimating the energy required

Based on the nth order grinding kinetic equation and the theory of linear additivity in the grinding process, the grinding kinetic characteristics of the feed and the circulating load in standard Bond rod-mill grindability tests are studied.A new method of simulating the calculation of the Bond rod-mill work index by using the grinding kinetic test data of the feed is proposed.
The types of mills are distinguished by their working principles: by pressure, impact, hammer, or shear. Mills could be equipped with a screen for grain size control and separation. The FAM product range includes impact mills, roller mills, hammer mills, ball mills and rod mills.

Our experts welcome the opportunity to assist you with circuit and circuit control design as well as start-up, operation, and optimization of your mill.
determination of the work index for ball and rod mills in 1952 and modified it in 1961. The standard Bond ball mill grindability test is a closed circuit dry grinding test with a 250% circulating load. The standard procedural outline of the test is stated in (Bond) 1961. The work index for a ball mill, Wi, is then calculated from the following ...

The Bond ball mill work index test is thought to be additive because of its units of energy; nevertheless, experimental blending results show a non-additive behavior.  The SPI(R) value is known not to be an additive parameter, however errors introduced by block kriging are not thought to be significant .
