JK Bond Ball Mill Test Since its introduction in the 1960s, the Bond Ball Mill Work Index (BBMWi) parameter has been extensively used in predicting ball mill power draw. Use of Work Index Along with comminution circuit design the index parameter is widely used in tracking mill performance. Due to the age and lack of controls for the test,
Jul 30, 2020· An improved method using less mass compared to the Bond Ball Mill Work Index test. The JK Bond Ball Mill (JKBBM) test, is a locked cycle grindability test conducted using a standard oratory Bond Ball Mill with the same steel ball charge and material feed size (100% passing 3.35 mm) as the Bond Ball Mill Work Index test. The test requires approximately 50% less material than the Bond Ball
A Bond Ball Mill Work Index test is a standard test for determining the ball mill 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 . Get P

The ability to simulate the Bond index test also allows examination of truncated ball mill feed size distributions on the index. For grinding circuits where the feed to a ball mill is sent directly to the classifier and the cyclone underflow feeds the ball mill (see Figure 3.10), a question arises as to whether this pract will alter the ball mill index (BW i) of the material
