“out of the 1500 t/h of coal delivered from the dozer to the processing plant, 225 t/h were fines smaller than 2 mm, but with the surface miner, this figure is closer to 185 t/h,” fennell adds. the wirtgen surface miner delivers more than 70% target size.cut, crush & load in a single machine,however, nac noted significant additional benefits with more consistent material to rom including reduced top size and less fines, less dilution, lower plant energy consumption and lower unit mining costs. nac's managing director, andrew mcdonald, said 'i am impressed with the economical, modern and environmentally friendly wirtgen surface miner..the influence of material properties on equipment,crushing and screening design measures. the large size lignite and stones have to be reduced to about -300 mm in a feeder breaker. then the -300 mm size lignite has to be reduced to -50 or -100 mm in a roll crusher or roll sizer to minimise the generation of fines. for.properties of coal,in a coal handling system, crushing is limited to a top size of 6 or 4mm. the devices most commonly used for crushing are the rotary breaker, the roll crusher and the hammer mill. it is necessary to screen the coal before crushing, so that only oversized coal is fed to the crusher. this helps to reduce power consumption in the crusher
