Sealing assembly for a ball mill pulverizer Know More. In the operation of any type of plant using pulverized coal for fuel it is common practice to supply raw coal to a ball mill pulverizer to reduce the size of the coal and mix it with air The main component of a typical ball mill is a large drum with hollow trunnions at each end forming an extension of the drum and providing space for
Crushed ore is fed to the ball mill through the inlet; a scoop (small screw conveyor) ensures the feed is constant. For both wet and dry ball millsthe ball mill is charged to approximately 33% with balls (range 30-45%). Pulp (crushed ore and water) fills another 15% of the drums volume so that the total volume of the drum is 50% charged.

SHORT DESCRIPTION: Cast iron ball set in a wooden plaque. NOTES: This item was used in the coal pulverizer.Efficient coal combustion requires that all the carbon particles in coal should get sufficient air to burn and release the heat. When coal is burned on grates without any change in size or pulverizing its large size means that some of the carbon particles do not come in contact with the
