Feed size: 25mm Processing capacity: 2-38t/h Effective volume: 4.5-75m3 Application range: Mainly used for grinding hard coal.At the same time, it is also suitable for coal and ore powder system in cement, metallurgy, chemical industry,etc. Material: Coal, cement ore, calcite, cement clinker, dolomite, clay, gangue, barite, gypsum, etc.
Coal mill is a machine that breaks coal into pulverized coal. It is an important equipment of pulverized coal furnace.Coal grinding process is the process of coal being broken and its surface area increasing.To increase the new surface area, the binding force between the solid molecules must be overcome, thus consuming energy.Coal is ground into pulverized coal in a coal mill, mainly by crushing, beating and grinding three ways.
6.Changing the ball bearing of the ball mill to a rolling bearing not only has a large bearing capacity, but also has a long service life, which can increase the service life of the sliding bearing by more than 5.
The material enters the ball mill bin spirally and uniformly from the feeding device through the feeding hollow shaft. There is a stepped or corrugated liner in the bin, which contains steel balls of different specifications. The cylinder rotates to generate centrifugal force to bring the steel ball to a specified height and fall. Heavy impact and grinding effect on materials.After the material is coarsely ground in the warehouse, it enters the second warehouse through a single-layer compartment board. The warehouse is set with a flat lining board and fine steel balls inside to further grind the material.The powder is discharged through the discharge grate plate to complete the grinding operation.
