Grinding Mills for Gold Mines / Vertical Grinding Mill for Raw
Material
Raw mill is mainly used for grinding cement raw materials. It can also be
used for grinding various ores and other materials in electric
power, metallurgy, chemical industry and other industry. Raw mill
has features such as high capacity, high efficiency, energy saving
and environmental protection.
Raw mill usually is used for grinding various ores and other
materials in cement, electric power, metallurgy, chemical industry
and other industry.
Structure
Raw mill is mainly consisting of feeding device, big gear wheel,
discharging device, cylinder, grate plate, hollow shaft, liner,
driving device and other components.
1. The inlet device is consisting of inlet chute and spiral
cylinder. There are lining plates in the inlet chute, which extend
the working life of the inlet device.
2. Cap is made of high-quality carbon steel and the hollow shaft is
cast moulding, combining together to ensure its safe and reliable
operation.
3. Inside the raw mill, different stages have different lining
plate structure, which will greatly improve the grinding
efficiency.
4. Main bearings are sliding bearings, which has good strength,
ductility, polymerism, anti-frication, abrasion resistance,
lubricity and thermal conductivity. It is able to meet the
lubricated requirements of the hollow shaft well and easy to
change, applying to low speed, heavy load working condition of raw
mill.
Our Advantages:
1. Product fineness is adjustable and uniform.
2. Relatively low energy consumption, low wear, low operating
costs.
3. High grinding efficiency, less wear and tear.
4. Low investment costs, simple process.
