The Equotip3 is a versatile portable metal hardness tester. Its' measuring principle is a simple, dynamic hardness test. An impact body with a hard metal test tip is propelled by spring force against the surface of the test piece. Deformation will take place on the test surface which results in loss of kinetic energy.

Simulating the Bond rod mill grindability test

The ball mill grindability test is used for describing ore hardness and it is so widespread that the Bond Work Index generated from the test is often referred to as an ore characteristic. The ore resistance to grinding and energy consumption can be expressed using the work index and Bond's Third Theory. The Bond Third Theory method is widely ...

Fast test method for the determination of the grindability …

The standard laboratory grindability tests can be applied to the grinding of materials in a relatively coarse particle size interval (Bond method: x < 3.36 mm, Hardgrove: x = 0.59–1.19 mm, Zeisel process: x = 0.75–1.00 mm).However, there has been huge industrial demand for the production of different kind of fine materials for few decades.

Secrets of the Bond Ball mill grindability test

The ball mill grindability test sometimes referred to as the Bond test was developed in the 1930s by the Allis Chalmers company to help them perform ore hardness characterisation testing to assist in industrial mill sizing Maxson et al, (1933). It was extended by Bond (1952) to provide a work index result that was empirically calibrated
