Vertical Raw Mill Compact Layout System Equipment With Light Weight
Vertical Raw Mill Working Principle:
The raw material from dosing station after weighing, transported into inlet of vertical mill by belt conveyor, then fed into rotary air lock of vertical mill with outer recycle materials, after the grinding, drying, separating, the crude material comes back grinding disc for grinding again, the qualified product will be brought into cyclone filter through separator, the product collected by cyclone filter and powder from bag filter at the kiln tail comes into raw meal homogenizing silo by air chute, bucket elevator and so on.
The part of exhaust gas from cyclone filter came back into air inlet of vertical mill, and other will be discharged into atmosphere through kiln system filter, fan and chimney.
The heat air source of raw material vertical mill is from high temperature fan and preheater exhaust gas.
Vertical Grinding Mill Advantages:
1. The material is mainly broken and pulverized by the weight of the roller and the pressure of the pressurizing device. During the grinding process, 1 the material is always subjected to the pressure of the grinding roller while the material between the grinding roller and the millstone is subjected to the effect of multi-directional stress, thereby improving the grinding capacity and grinding efficiency.
2. As the material get fully contact with the hot gas after enter the mill, and then suspended in the hot gas after grinding, which can fully 2 s ed ing exchange heat energy and dry the material while grinding.
3. The grinding pressure of roller is provided by the hydraulic system, which is passed to the grinding roller by the pressure device and the rocker device and then applied to the material. Owing to the pressure regulation of the hydraulic system, it can change the grinding pressure to meet the requirements of grinding materials with different hardness.
4. For avoiding the violent vibrati situation caused by the direct contact of the roller and disc when the machine in tion, there should be 4 ing opera certain gap between the grinding roller and disc. A position limiting device is designed not only to adjusting the gap size between them, but to observing the material thickness under roller any time, thereby ensuring the mill with safety and economic operation.
5. Roller sheath and liner adopt high hardness alloy wear-resistant materials, with less abrasion and long service life. 5 disc
6. Under the function of accessory hydraulic cylinder, the roller can be removed outside of mill for inspection and repair easily.
7. There has device around the grinding disc to prevent disc base wearing, adjust the air speed of air ring and the material thickness, to guarantee 7 the vertical mill' capacity and operation economical.
8. The separator is 8 composed of converter motor, gearbox, rotor, shell and so on. The motor drive rotator through gearbox and getting different fineness product by adjusting the speed of motor.
9. The lubrication oil station provides oil to lubricating system of main gearbox and generation the circle lubrication to guarantee the main gearbox operation normally.
