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

Determination of Bond index of Birnin- Gwari Iron Ore

2014-3-6  Bond index is useful in designing of grinding system in mineral processing. In this study, the Bond work index of Birnin- Gwari iron ore in northern Nigeria is determined using modified Bond’s method using ‘reference ore’. Samples of iron ore were sourced using random method, reference minerals; marble and granite of known weight and iron ore

Procedure for determination of ball Bond work index

2009-1-1  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

Characterization and Comminution Studies of Low

2019-1-31  Bond work index studies were carried out for the BHQ and BHJ ores with different product fineness in order to evaluate the energy requirements in fine grinding. A higher Bond work index value was found for the BHJ ore (15.4 kWh/ton) than for the BHQ ore (12.4 kWh/ton).

Investigation on Iron Ore Grinding based on Particle

Starting from the first-order grinding kinetics defined by means of the Bond ball mill, this paper discusses a simplified procedure for a rapid determination of the work index by just two grinding

Evaluation of grinding circuits for iron ore

The work index (W i) is the comminution parameter that expresses the ore resistance to crushing and grinding. The Wi is equivalent to the needed kilowatt hour per short ton, in order to reduce an ore size distribution from the infinity value to 80%<100µm. Morrell (2003) proposed two factors to be included in the Bond equation. One is related

Investigation on Iron Ore Grinding based on Particle

2020-5-28  The new approach is adapted to identify the retention time (RT) of the iron ore in the mill, and the total RT taken for the blend sample in the Bond’s ball mill is considered as the reference grinding time for milling in the Laboratory Ball Mill (LBM). The desired narrow PSD (− 150/+ 10 µm) with acceptable hematite liberation is achieved
