Energy Efficient Drying Integrated Vertical Coal Mill Grinding Equipment
Description
Coal vertical mill can be widely used in cement, electric power, steel, metallurgy and other industries, and can also process coal gangue and other kinds of coal mines. Due to its special process and structure, the coal vertical mill has less dust and noise in the production process. The pulverized coal produced has high efficiency grading and excellent combustion performance. The coal vertical mill produced by our company has simple process and compact equipment, and the fineness of pulverized coal can reach 80 μ MR 3%, with stable fineness and uniform particle size.

Product Advantages
1. High efficiency and energy saving:
(1) High grinding efficiency and low energy consumption
(2) Large production capacity of single machine, which can make use of low valley power;
2. Easy maintenance and low operation cost:
(1) The grinding roll can be turned out of the machine by hydraulic device. The replacement of the roll sleeve liner plate and the maintenance space of the mill are large, and the maintenance operation is very convenient;
(2) The grinding roll sleeve can be turned over for use, extending the service life of wear-resistant materials;
(3) There is no need to distribute materials on the grinding plate before starting up, and the mill can be started without load, eliminating the trouble of starting up hard;
(4) Low wear, special materials are used for grinding roll and grinding disc liner, and the service life is long;
(5) High degree of automation: automatic control technology, easy to operate, unmanned operation can be basically realized in the workshop, saving operating costs;
3. High reliability
(1) The limiting device of grinding roll is adopted to avoid the violent vibration caused by material interruption during the working time of the mill;
(2) A new type of roller sealing device is adopted, which makes the sealing more reliable, and no sealing fan is needed, further reducing the oxygen content in the mill, and the explosion suppression performance is more excellent.
4. Low comprehensive investment cost:
It integrates crushing, drying, grinding and transportation. The process is simple, the system equipment is few, the structure layout is compact, and the floor area is only 50% of that of the ball mill. It can be arranged in the open air, and the construction cost is low, which directly reduces the enterprise investment cost.
5. Stable product quality:
(1) The material stays in the mill for a short time, which makes it easy to detect the particle size distribution and composition of the product, and the product quality is stable;
(2) The product has uniform particle shape, narrow particle size distribution, good fluidity and strong product adaptability.
6. Environmental protection:
(1) The whole system of HVM vertical mill has low vibration and noise;
(2) The system is sealed as a whole, operates under full negative pressure, and has no dust spillover. It can basically realize a dust-free workshop.
