Simulating the Bond rod mill grindability test -

2012-1-1  The Bond rod mill grindability test is a widely used tool to estimate the response of ores to rod milling. However, the mass of ore required to conduct the test, which can typically vary from about 8 to as much as 20 kg, may represent a challenge when sample availability is critical.The present work proposes an alternative procedure, which is based on the size-mass balance model with a ...

Breakage of coals in ring-roller mills Part 2. An

1998-9-1  A mathematical model has been developed for predicting unsteady behavior of a ring-roller mill. The model is based on specific rates of breakage, primary breakage distributions, classification actions of particles in the mill and mass transport relation of mill hold-up and flow rates through the mill.

Predicting HPGR performance and understanding rock ...

High pressure grinding rolls (HPGR) are becoming an increasingly popular energy efficient solution for comminution of hard rock ores. A significant barrier to the increased adaptation of HPGRs is the current requirement for large amounts of sample for pilot testing. The primary objective of the research was to develop a DEM based computer model for an HPGR to analyze the particle behavior in ...

2020-12-15  In addition, while the actual roller mill is equipped with a rotary classifier, the HGI mill is not equipped with the discharging system of grinding products. Thus, the easily grindable carbonized biomass with small tapped density may be a cause of the decrease of the grindability of coal using the HGI mill in the mixture.

Previous studies show that the grindability of limestones determines the wear rate ( Jensen et al., 2009a,b ). Thus, the study is targeted at quantifying the limestone texture with the aim of predicting the grindability. Very limited research is available on correlations between limestone petrography and mechanical properties.
