Bond Work Index an overview ScienceDirect Topics

The constant K 2 is also dependent on ore type and ranged from 1.4 to 1.5. A regression of Magdalinovic’s data including the feed 80% passing size gives an average value of 1.485 for K 2.If we extend this relationship to any sample of screened material then this gives an approximate estimate of the 80% passing size as 67.3% of the top size.

CORRELATION BETWEEN BOND WORK INDEX AND

The Bond's standard ball mill is used to determine the work index value of differ ent samples. The Bond work index is defined as the kilowatt-hours per short ton required to break from infinite size to a product size of 80% passing 100 µm. If the breakage characteristics of a material remain constant over all size ranges, the calcul ated work

CORRELATION BETWEEN BOND WORK INDEX AND

The crushing energy in mineral processing industry is usually determined by empirical Bond index, regardless of the mechanical properties of a rock. Although several attempts have been made to obtain the comminution energy based on theoretical approaches, it would be beneficial to examine this relation based on physical concept.

Procedure for determination of ball Bond work index in the

Jan 01, 2009· 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

Correlation Between Work Index and Mechanical Properties

Abstract The crushing energy for applications in the mineral processing industry is usually determined by an empirical bond index, regardless of the mechanical properties of a rock. Although several attempts have been made to obtain the comminution energy based on theoretical approaches, it would be beneficial to examine this relation based on a physical concept.
