Coal Processing & Delivery Premier Coal

After crushing, the coal is conveyed to a transfer station where it is sampled by automatic sampler. This sample is reduced in mass from the initial 165 kg by crushing and secondary sampling. The sample not required for analysis is returned to the product conveyor. The sample is collected and analysed every two hours. The sized product is delivered onto a longitudinal stockpile in thin layers

Coal assay Wikipedia

The particle size distribution of milled coal depends partly on the rank of the coal, which determines its brittleness, and on the handling, crushing and milling it has undergone. Generally coal is utilised in furnaces and coking ovens at a certain size, so the crushability of the coal must be determined and its behaviour quantified. It is necessary to know these data before coal is mined, so

Role of Tectonic Coal in Coal and Gas Outburst Behavior

An adequate supply of gas is required to transport outburst coal, such that the existence of coal particles smaller than the critical diameter is important. Our calculations indicate that the crushing work ratio of coal from the five outburst case ranges from 22.19 to 78.67 J/m2. Only the crushing work ratio of tectonic coal satisfies the requirement for these cases. Therefore, the properties
