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.. Below describes in general terms the Bond Work Index Procedure used by a Professional Metallurgical Testing Laboratory.

Bond Index Ball Mill / Rod Mill BT 100 XL - RETSCH

At least 15 to 20 kg sample material is required to simulate a closed grinding circuit in a ball or rod mill. The Rod Mill Work Index (RWI) is used for particle size determination in a size range from 25 mm down to 2.1 mm whereas Ball Mill Work Index (BWI) is used for the range from 2.1 mm down to 100 µm. Adjustment of grinding parameters:

Abrasion Test | Mining | SGS

The equipment consists of a rotating drum into which dry ore samples are placed, with an impact paddle mounted on a centre shaft rotating at a higher speed than the drum. The paddle is made from standard alloy steel hardened to 500 Brinell. The Abrasion Index is determined from the weight loss of the paddle under standard operating conditions.

Exercise Stress Test: Facts About Guidelines and Results

A stress test can be used to test for heart disease. Stress tests are tests performed by a doctor and/or trained technician to determine the amount of stress that your heart can manage before developing either an abnormal rhythm or evidence of ischemia (not enough blood flow to the heart muscle). The most commonly performed stress test is the exercise stress test.

Smith and Lee (1968) have compared the data obtained through the standard Bond test and those from an open-cycle milling. Kapur (1970) analyzed the data obtained during the execution of the Bond standard test, developed a mathematical algorithm that simulates this process and, on the basis of it, assessed the Bond work index.
