Many coal pulverizer designs do not incorporate any filtration in their lube circuits The pulverizers that do not incorporate filtration use coarse filtration such as 40micron cleanable mesh or 200micron cleanable, stacked disk filters Such OEMsupplied filtration is often unable to keep up with the inherently high ingression rateCoal Pulverizer are designed to reduce the size of the incoming raw coal to a fineness that will result in good furnace performance The grinding surface in the pulverizer resembles a shallow dish or bowl Therefore the name “Bowl Mill” has been adopted to refer to this piece of equipment Components of Bowl Mill Coal Pulverizer GearboxBowl Mill Coal Pulverizer COAL HANDLING PLANTS2011年8月1日 The pulverizer will then have the capability to produce pulverized coal that is 70% passing 200 mesh fineness (Figure 2, red line) This is commonly expected performance for this model pulverizerPulverizers 101: Part I POWER MagazineThe coal is ground so that about 70 % will pass through 200 mesh (0075 mm) and 99 % will pass through 50 mesh (0300 mm) normally 70 % through 200 mesh and less than 2% on 50 mesh; Coal parameters affecting pulverizer output While selecting a pulverizer, the coal characteristics play an important role The Hardgrove index, Coil Pulverizers for Boilers Bright Hub Engineering
