摘要: In the present study, effect of microwave energy on grindability high-ash (46.39%) and sulphur (3.99%) Turkish coal has been investigated. Coal samples (-9.52+3.18 mm) was treated by at a frequency 2.45 GHz with different power levels (0.48-0.64-0.80 kW) residence times (30-150 s.). order to determine crushing/grinding resistance low ranked lignite oven, Impact Strength Index (ISI) test applied for each untreated sample compared other. Experimental results have shown that significant increases in were achieved when exposed radiation. The ISI decreased up 96%.
