How To Check The Quality Of Grinding Mill

15.06.2021· The Influence Of Material Hardness On The Mill. The hardness of the grinding material is usually characterized by the Mohs hardness (range 1-10), which differs depending on the type and content of inclusions in the original ore. Generally speaking, the material has high hardness, poor grindability, and high wear of the mill. Therefore, the hardness of the material is directly related to the

Analyzing the Effect of Ball Size on SAG Grinding

The analysis of the influence of ball sizes in SAG grinding has not been developed in detail by considering the effect on process parameters inside the mill, grinding efficiency or internal classification. Historically a conventional grinding reference has been made on the empirical procedure developed by Azzaroni (1980). Further to Azzaroni's methodology, Sepulveda (Sepulveda, 2007

Small-Scale Tests to Characterise Ore Grindibility

The resistance of ore samples to breakage (or hardness) is measured through grindability testing. Several grindability tests have been developed over the years for different applications and each test has its own strengths and weaknesses. Grindability testing is a compromise between test cost and its deliverable(s). Because a large fraction of the cost component is driven by the sampling
