Best Supplier for Pulverized Coal Vertical Mill

Pulverized coal vertical mill also known as grinding coal mill or coal mill, professional for cement, power plants, steel and other fields of raw coal, bituminous coal material superfine grinding. ZK Corp coal mill with a special structural design and production process, manufacturing quality to the leading domestic level, is the raw coal smelting, bituminous coal material, to achieve efficient use of clean coal equipment.

First of all we have to talk about the working principle of vertical mill: the material through the cutting tube fell to the center of the disc, constant speed rotation of the disc with the role of centrifugal force to spread out the material evenly, paved to form a certain thickness of the bed, the material at the same time by the disc on a number of roller rolling, and was crushed. In the continuous drive of the centrifugal force of the material continue to move to the outer edge of the disc, when leaving the disc material encountered through the wind ring into the grinding of hot gas and then rise, the mill through the middle of the shell into the separator, in this process, the material and hot gas carried out a full heat exchange, the water was quickly evaporated. The powder is controlled by the size of the finished product of the roller mill, the particles larger than the specified size are separated and returned to the disc to meet the fineness of the material through the separator into the dust collector, the finished product is sent into the finished product.

Advantages of coal vertical mill as follows:
1. High grinding efficiency and low power consumption.
2 .Low metal consumption in unit product.
3. Bed grinding with low noise.
4. Negative pressure and low dust pollution.
5 .The technical process is simple and material grinding, drying and separate can be achieved at the same time.
6. Small floor space, compact layout, system equipment with light weight and low investment for civil construction.

Pulverized coal vertical mill gathers grinding, drying and powder selecting as a whole, with high grinding efficiency and high drying capacity (the maximum material moisture can be up to 15%). The vertical mill adopts dynamic powder selecting device, which comes with high powder-selecting efficiency and convenient adjustment of fineness.
