Bond's approach consists of determining the ore hardness characteristics, or Work Index (Wi) via standardized laboratory testwork. The full suite of Bond comminution tests provide the Ball Mill Work Index (BWi), the Rod Mill Work Index (RWi), the Crusher Work Index (CWi) and the Abrasion Index (Ai).

stirred mills are becoming increasingly popular in the mineral processing industry. This work presents hypotheses of a new methodology to predict the product size distribution of a vertical stirred grinding mill using the population balance model. Initially, detailed experimentation was carried out in a Bond Ball Mill .

circuit, comprised of a m diameter x m long SAG mill and a m diameter x m long secondary ball mill in closed circuit with cyclones, was built using SAG Power Index and Bond Ball Mill Work Index testing to determine the grinding energy requirements.

Kinetic grinding test approach to estimate the ball mill work index 343 The W i parameter is obtained from Bond's ball mill grindability test (Bond, 1961). This test is performed according to the standard Bond procedure which proposed model is presented in Eq. 1. This standard grindability test simulates a .

However, multivariate complexity and compositional data constraints can make this analysis challenging. This study applies unsupervised and supervised learning to establish relationships between the Bond ball mill work index (BWI) and geomechanical, geophysical .

The Bond ball mill grindability test is run in a laboratory until a circulating load of 250% is developed. It provides the Bond Ball Mill Work Index which expresses the resistance of material to ball milling. This happens after 7–10 grinding cycles, which shows that the procedure is a lengthy and ...
