Weedon took a number of rock samples and broke them using the twin pendulum device described in Section 4.5.3 He then sized the products and subjected them to QEM'SEM analysis. The result was a series of data sets which contained information on the degree of liberation of selected minerals in 'each product size class following breakage of a ...

Pendulum Test. A number of specimens of varying sizes are tested to generate breakage curves from which the JKSimMet simulation parameters are calculated. The test is a useful adjunct to the other media competency tests: once the type of circuit that is best suited to the ore is identified, JKSimMet can be used to verifying initial mill sizes. 514

3.3.1 Bond Pendulum Test In this test the energy required to crush a dry ore particle by the impact of two swinging hammers is determined. The standard method adopted by Bond is as follows [5]: Two equal hammers, 13.6 kg each, (Fig. 3.4), about 0.7 m in length and the striking face 50 x 50 mm are suspended from two (bicycle) wheel rims.
Jun 16, 2015· A crude test procedure description of this Crushability test follows in that rock samples smaller than 75 mm but greater than 50 mm are placed 2 "hammers" of 13.6 kg each and mounted to swing on bicycle wheels. Both hammers of the "pendulum" will …

Adjustable crushing angle Repeatable crushing results Safe two-hand operating buttons The Bond Crushing Work Index (CWI) describes the competency of the ore at larger particle sizes. It is used for the calculation of ...
A twin pendulum device was also developed by Allis-Chalmers, and found to accurately predict rock crushability and crusher product size distribution (Moore, 1982). However, Napier-Munn (et al., 1999) has found that twin pendulum devices are restricted in their energy and particle size range, and that operating the device is time consuming.

Bond Rod Mill Index Test (BRMWI) A Bond RMWI test is a standard test for determining the Rod Mill Work Index of a sample of ore. It was developed by Fred Bond in 1952 and modified in 1961*. The BRMWI is a measure of the resistance of the material to crushing and grinding. It can be used to determine the grinding power required for a given
