2022.1.1  As testing methods, grindability measurement can be divided into two general categories: the Bond (G bg) and the Hardgrove grindability index (HGI). While the Bond grindability is associated with horizontal tumbling (drum) ball mills, the Hardgrove grindability is mainly associated with vertical roller mills (VRM) have been the most

A Comparative Study of Energy Efficiency in Tumbling Mills

The test procedure for the first series of grinding tests follows the well-known Bond ball mill grindability test [2,23] precisely. In the Bond ball milling test, a locked-cycle test, the fresh feed to the test is crushed down to 100% under 3.35 mm. The mill grinds a constant 700 mL of ore. After each grind, the mill contents are screened to ...

Determination of the Bond work index on samples of non-standard size

2012.11.21  Introduction. The Bond grindability test for determining the Bond work index, W i, is conducted in a Bond ball mill having the dimensions D × L = 305 × 305 mm and a speed revolution of 70 min − 1.The mill is loaded with balls from 15.5 up to 30.6 mm in diameter, having thus a total mass of 20.125 kg.. This test simulates a closed circuit of
