Coal Vertical Mill 40 T/H Coal Mill / Energy Saving Vertical Coal Mill / High Production Low Consumption

Product Descripition:

NO.1 Coal vertical mill can be applied in industries such as cement, electricity, steel, metallurgy, etc. Due to its special process and structure, the coal vertical mill produces less dust and low noise during the production process, resulting in high efficiency and excellent combustion performance of the produced coal powder. The coal vertical mill produced by our company has a simple process, compact equipment, and a coal powder fineness of up to 80% μ MR 3%, with stable fineness and uniform particle size.

NO.2 Structural principle:
The coal vertical mill is driven by an electric motor and drives the grinding disc of the coal mill to rotate through a planetary reducer. The 2-4 grinding rollers on the grinding disc rotate under the driving force of the grinding disc. The raw coal entering through the coal chute is distributed on the grinding disc. Due to the hydraulic loading force, there is compression between the grinding rollers and the grinding disc, causing large particles of raw coal to be crushed. The sliding friction force generated by the relative motion between the grinding roller and the grinding disc is used to achieve the crushing of small coal particles; During the grinding of raw coal in the mill, hot air (usually below 300 ℃) is introduced into the vertical mill to dry the moisture of the raw coal and meet the requirements for finished coal powder; The ground coal powder is transported by primary air into the separator for separation. The qualified coal powder is separated and transported to the coal powder bin, while the unqualified coarse coal powder is returned to the mill for re grinding.

NO.3 Technical advantages:
High efficiency and large production capacity
Higher work efficiency, compared with old vertical mills of the same model, the output has increased by 20-50%, and the operating power consumption of the coal mill can be greatly reduced;
High quality coal powder
It adopts advanced dynamic and static combination separators, which have high classification efficiency and large adjustment space. The fineness of selected powder can reach 0.08 mm, and the sieve residue is less than 8%, which can meet the fineness requirements of most low-quality coal or anthracite powder grinding in cement production lines.
High system security
Coal vertical mill
By adopting explosion-proof measures such as temperature detection devices and online gas analyzers, the safe operation of the equipment is effectively ensured.
Complies with environmental standards
Through a unique sealing structure design, the entire system is in a negative pressure state, with no dust overflow and low noise during the production process. The coal powder is collected using a dedicated gas box pulse dust collector for coal grinding, and the dust emission concentration meets national standards.
