VM Series Coarse Powder Vertical Mill

VM series vertical mill is an energy-saving advanced grinding equipment that integrates drying, grinding, classification and conveying.

VM vertical mill has advantages of high grinding efficiency, low power consumption, large feed granularity, easy product fineness adjustment, simple equipment process, small footprint, low noise, low dust, easy operation and maintenance, low operating costs, less wear-resistant materials consumption, etc.. It can be widely used in power, metallurgy, cement, chemical, non-metallic ore and other industries, mainly for grinding of cement raw materials, clinker, power plant desulfurization limestone powder, slag powder, manganese ore, gypsum, coal, barite, calcite, bauxite, etc..

ADVANTAGE

1. High efficiency

(1) Low energy consumption, high efficiency, 40%-50% lower energy consumption than ball mill;

(2) High single machine output, can use off-peak electricity;

(3) Vertical mill technology is initiated by the country, it can improve the competitive strength of the enterprises in local area or even in the country;

2. Easy maintenance, low operation cost

(1) The rollers can be pull out from the mill by the hydraulic device, which is convenient for plate-replacement and bigger maintenance space;

(2) Left and right side of the roller shell can both be used for prolonging the working life;

(3) The mill can run without raw material on the grinding table, which erases the difficulty in starting;

(4) The roller and grinding table are made from special material for longer working life;

(5) High degree of automation: Applied Germany Siemens PLC series with automatic control system and can realized easy long-distance control and unmanned operation.

3. Low investment cost

The equipment features in a combination of crushing, drying, grinding, and conveying, simple process flow, reasonable and compact layout, space-saving (50% less than ball mill), lower foundation cost and workshop cost in the field;

4. Stable powder quality

(1) Material stay a short time in the mill, easy to control fineness and chemical component;

(2) Regular powder shape, narrow fineness range, good fluidity, extensive application;

5. Reliability

(1) Rollers with height-controlled device, which could avoid strong vibration caused by the lack of material on the table;

(2) Newly-designed roller sealing component ensures the reliable sealing without sealing the blower, which can lower the oxygen content in the mill to prevent the possibility of explosion;

6. Environmentally friendly

(1) Lower vibration and noise;

(2) The whole facility is all sealed and operates under negative pressure, no powder overflow, no-dust workshop can be realized.

(3)Vertical mill is the better equipment to lower power consumption in the mill industry, which is also what the country advocate and a must to increase the enterprise competitiveness in China powder industry.

7. High Automatic Level

(1) PLC automatic control system, remote control, easy operation and maintenance, lower labor cost.

8. Strong Drying Ability

(1) Vertical mill features in high trying ability with hot air direct contact with the material in the mill, maximal feeding moisture of 15% is workable. A separate drying machine and energy for the mill system can be both saved. The vertical mill can satisfy the materials in different humidity by adjusting the hot air temperature.
