point of combustion. In the airconveyed directfired coal pulverizing system, used extensively in the industry today, there normally exists a combustible coal/ air mixture in the burner lines and pulverizer equipment. Hence there is the continual danger of fires and, under certain conditions, explosions.
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 rate.
Holmes Model 350 is a laboratory benchtype sample pulverizer that has a capacity of 400 grams of coal per minute using a " diameter perforated screen. It is recommended for pulverizing 4mesh and smaller material to minus60 mesh.
