Cement Vertical Roller Mill

For the cement market were 30,25,20,10,eight.eight tons of annual production and other industries use to meet the customers of various supplies with various yield and grinding needs. At the identical time I also have fine vertical grinding mill, the State Development Center has fine vertical cement mill as the “Eighth 5-Year” period focused on advertising the application of high efficiency, new power-saving items.
The working principle of vertical roller mill
1, the major structure and function
Roller is the primary material for rolling mill parts. Mill constructed with two pairs of roller, every pair of rollers mounted on the very same shaft, rotating at various speeds.
Disc fixed to the reducer output shaft, the upper part of the disc material bed, the bed material a circular groove.
PRM-kind separator primarily composed of vertical roller mill ,roller, disc, compression device, reducer, motor, housing and other elements.
Fineness of separation is an critical element of the choice, which consists of adjustable speed drives, rotor, guide blades, housing, meals, fighting off the cone material, composed of the outlet, and the separator works comparable.
Pressure device is known as the grinding pressure of the elements provided by the high pressure oil station, hydraulic cylinder, rod, storage and other elements, in a position to exert adequate pressure roller grinding of components.
2, the operating principle of vertical roller mill
The material flow via the separator, in the function of guide vanes and the rotor, the coarse material to the disc from the hopper cone, the fine powder with a mill with air, dust collection device in the system to collect, is the item, the material in the get in touch with procedure with the gas being dried to the required product water, by adjusting the angle and the wind guide vane separator rotor speed can be diverse fineness of the solution.
Motor through reducer drive the disc rotation, the present hot air from the air inlet into the mill, the material from the feed opening falls on the central disc the centrifugal force, material to the disc edge and moved across the ring groove on the disc by the grinding roll rolling and grinding, to the edge of the disc, moving by means of the air with the wind at the beginning of big particles falling back to disc on the direct re-grinding.
Compared with the ball mill, vertical roller mill with the following features
Compared with the cement vertical mill to mill the advantage is obvious, in order to establish a far more intuitive description of the qualities of MPS vertical mill, following the annual output of 10 tons of cement and production of raw material preparation program, for example, compared with the two HRM vertical mill and ball mill kinds of program indicators.
Grinding efficiency drying massive capacity into the grinding material Liaodu large, medium and huge vertical mill can save two broken items, chemical stability stars are homogeneous gradation, solution Liaoduo uniformity is conducive to burning method is basic low noise, less dust, the operating atmosphere clean metal loss, high utilization use of the economy.
Assuming an annual output of 10 million tons of cement in order to meet production wants, could use the following two alternatives:
Programme 1: HRM1300 vertical mill grinding system
Programme two: @ two.two six.5 closed-circuit grinding program
Table II installed capacity of the two applications, technical and financial indicators in Table III.
As can be observed from the above comparison, the decision of vertical roller mill to lessen annual operating charges only 380,200 yuan, and the level of technologies and merchandise to enhance yield, save power, increase the operating atmosphere, decreasing noise and pollution, and improve potential to adapt to other elements of the play is not assess the extended-term benefits.
