Theoretically, the Whiten model was initially used and further modified to predict the PSD of coal gangue in a doubleroller crusher [17,18]; additionally, a generalized selection function [19] was applied for a twotoothed roll crusher and the breakage function was extended to coal gangue. All results were finally validated versus data ...
The selection of the right crushing equipment is influenced by many factors some of which are upstream of the crushing plant ( blasting pattern and mining method) and others which are downstream of the crushing plant ( mill and grinding circuit selection). Crushers have more efficient transfer of applied power to the breakage of rock ...
In large coal preparation plants with a capacity of 30 million tons/year, the belt speed can reach 7 m/s and the thickness of the material layer can reach 500 mm. Therefore, in highthroughput and complex environments, the problem exists that harmful feeding materials such as iron and gangue are not easily detected, and thus fault diagnosis in the crushers lags behind.
As experience shows, when one determines the energypower parameters of crushing and grinding processes by using the existing methods, the power of motors used in drives of existing crushers of various types often turns out to be excessive [10, 11].In this case, the drive will operate at a relatively low load (ratio of the power consumed by the working body of the machine to the rated motor ...
