Outotec Mergan method is faster than the Bond ball mill test, and requires less sample material. However, the Mergan method gives grinding energy consumption, which can be used to calculate Mergan work index, but this Mergan work index differs from the Bond work index. Therefore, it is needed to analyze if the Mergan work index correlates

Standard Bond Ball Mill Grindability Test MethodProcedure. Here is the old AllisChalmers Bond Work Index Grindability Test Procedure. The standard feed is prepared by stage crushing to all passing a 6 mesh sieve, but finer feed can be used when necessary.
Test Method For Bond Ball Mill Work Inde. The test determines the bond rod mill work index which is used with bonds third theory of comminution to calculate net power requirements when sizing ball millsquick method for bond work the aim of this study.
It is a ''locked cycle'' test conducted in closed circuit with a laboratory screen. The Bond Ball Mill Work Index can be used in the design calculations and simulations using JKSimMet of a new grinding circuit. A Bond Ball Mill Work Index may also be used in the simulation and optimisation of existing mill(s) and the associated grinding circuit(s).

The aim of this study was to develop a new method for assessing the Bond work index in a ball mill (BBWI), which is based on a first order kinetics present in the Bond ball mill for grinding mineral raw materials (Austin et al., 1981; Ahmadi and Shahsavari, 2009). Theoretical basis of quick procedure
Bond Work Index Procedure and Method. This Grindability Test or Bond Ball Mill Work Index Procedure is used to determine the Bond Work Index of minus six mesh or finer feed ore samples. These equation application methods are used to process <1/2″ ore samples in a Ball Mill using a standard ball charge.
Oct 15, 2015· Bond Work Index (BWI) Hardgrove Grindability Index (HGI) tests for biomass coal. • BWI can predict the potential for mill choking of biomass in a tube and ball mill. • HGI is a poor method of predicting grindability of biomass in vertical spindle mills. • Pellets should be composed of predensified particles close to the target size. •
1. Introduction. 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 for grinding, and for ball mill ...
