The Janka scale is used to determine the relative hardness of particular domestic or exotic wood species The Janka test measures the amount of force required to embed a " steel ball into the wood to half of its diameter Woods with a higher rating are harder than woods with a lower rating The scale used in the table is pounds force
The first step in the mining and processing of nearly any mineral ore is comminution Since the oil embargo of 1979 the mining companies have been striving to reduce energy consumption and costs The first serious step was the introduction of in pit crushing in the early 1980s With in pit crushing accepted as a standard design mode the energy saving emphasis turned to
The output product of a jaw crusher was studied by Olaleye [7] and Mu [8] in terms of how it varies with ore 40 body strength as well as using Discrete Element Modelling DEM techniques
Brinell [HB] is one of the most common units used for listing the hardness of steel materials The test is done with a 10 mm steel ball pressed with 3000 Kgf 6 614 Lbf Common values for machined materials range from 100 HB for very soft materials up to 650 HB for heat treated The advantage of Brinell [HB] over Rockwell [HRC/HRB] is that the whole range is
·Ball charge fraction of volumetric loading and ball size Mill operating conditions including mill speed for circuits with variable speed drives density and total mill load; The effect of feed hardness is the most significant driver for AG/SAG performance with variations in ore hardness come variations in circuit throughput The effect of
