Using highvoltage electrical pulses to crush coal in an air ...
WEBSep 1, 2016 · To improve the efficiency of energy utilization while reducing the processing cost, we studied the feasibility of applying electrical fragmentation to crush coal in an air environment. Coal seams are dualporosity reservoirs with a natural fracture system, known as "cleats". Their surface is macroporous, but the coal matrix is microporous [33].
