Bond Work Index an overview ScienceDirect Topics

Bond impact crushability work index (CWi) (Bond, 1963) results reported for iron ores vary from hard iron ore (17.7 kWh/t) to medium hardness iron ore (11.3 kWh/t) and friable iron ore (6.3 kWh/t) (Table 2.11; Clout et al., 2007).

Bond Work Index Formula-Equation

See this useful summary Table of Bond Work Index by Minerals. For any circuit, whether a crushing circuit, a rod mill, or a closed ball mill circuit, the Work Index always means the equivalent amount of energy to reduce one ton of the ore from a very large size to 100 um. The sample was received crushed appropriately for the ball mill test.

Bond Work Index an overview ScienceDirect Topics

The Bond work index is not solely a material constant but is influenced by the grinding conditions. For example, the finer the grind size desired, the higher is the kWh/t required to grind to that size. Magdalinovic [38] measured the Bond work index of three ore types using different test screen sizes. He produced a correlation between the mass of test screen undersize per revolution, G, and

This index takes into account the material ore hardness and feed size, mill speed, material recirculation, desired fineness, etc. When the material exits the mill, the iron ore is classified using cyclones or vibrating screens that separate fine and large particles. The large particles are diverted back into the crusher and the fine particles will undergo a spiral gravity separation process.

Improved characterisation of ball milling energy

15/01/2018 The Bond test can overestimate the reduction in ball milling energy requirements for HPGR products, not due to a change in the breakage characteristics of the particles, but because the Bond test feed for a sample crushed in a HPGR has a greater fines content than a conventionally-crushed sample. This paper rigorously assesses the actual change in BBWi achieved through the

Mill (grinding) Wikipedia

A mill is a device that breaks solid materials into smaller pieces by grinding, crushing, or cutting. Such comminution is an important unit operation in many processes.There are many different types of mills and many types of materials processed in them. Historically mills were powered by hand or by animals (e.g., via a hand crank), working animal (e.g., horse mill), wind or water ().
