Modeling of coal breakage in a double roll crusher
Fig 2 shows a schematic view of our modified roll crusher model which is based on the model by Austin et al [12] but includes an additional agglomeration step after the breakage process Given that Eq 8 is a non linear equation for which closed form solutions are not applicable an iterative calculation procedure was carried out using the scheme shown in Fig 3
The complete set of crusher equipment used in coal mines
A cone crusher or an impact crusher can be used as a secondary crusher This stage may have a capacity of around 500 tph Tertiary crusher optional If the final product requires a very small particle size a tertiary crusher can be added to the process This could be a vertical shaft impact crusher VSI or a high pressure grinding roll HPGR
