Introduction :Coal Size Reduction Ball Mill. effect of ball size distribution on milling parameters size on milling rate for a south african coal. a series of batch grinding tests
The ball mill is also suitable for the JK model, where tests on monosized feed samples are conducted to investigate the effect of feed particle size on ore breakage results. Shi et al. performed ball mill breakage characterization and developed a ball mill breakage model using new ore . The JKFBC test relates to ball mills in the sense that
The working principle of the coal mill is illustrated in Fig. 1.In normal practice, there are two coal feeders for each mill. Once the raw coal flows into the mill barrel with hot primary air, the iron balls inside the rotating barrel will continuously crash the coal until it is fine enough to be blown out the mill to the furnace.
ATOX coal mill. Working principles The raw coal enters the mill via a rotary sluice and feed chute and is discharged onto the rotating grinding table. The rotation of the table accelerates the flow of material towards the grinding track, where the coal is ground between the table and the three rollers. The coal then continues over the dam
Feeding size: ≤110mm. Capacity: 570t/h. Motor power: 1101400kW. Applications: Vertical coal mill is mainly used for grinding raw coal, bituminous coal, and other fuels into coal powder, which is supplied to rotary kiln and other kilns in the cement plant and thermal power plant.
