The vertical mill is componed with separator, roller, disc, pressure device, reducer, motor, shell and other parts. The separator is the key part to ganrantee product fineness, which is consist of drive system, the rotor, the wind guide leaves, shell, coarse powder drop cone, and outlet device.

2. Vertical mill inner structure detail introduction

1) the roller is an important part to crushing material, which consist of roller sleeve, roll heart, shaft, bearing and roller bracket and other components. For each machine there are 2 to 4 grinding rollers.

2) the disc is finxed on vertical axis of the reducer, and it is driven by the reducer. Different vertical mill type has different disc shape, the disc is assembly by plate seat, lining, block ring and other parts.

3) the pressurizing device is key part that provide the grinding pressure, which consist of high pressure oil station, hydraulic cylinder, rod, accumulator and so on.

4) the reducer not only play an role in deceleration, transmission power and driven the rotation of disc, but also stand the pressure by disc, material and drinding, etc.

3. Vertical mill principle in detail

The material lifted by pressure, and through hydraulic pneumatic device to crushing material, the pulverized material is moved to the edge of the disc, and the material is discharged from the nozzle ring around the disc to raise the material In the device. The coarse powder is returned to the disc after separation, and the fine powder is collected and discharged in the dust collector.

There are many kinds of vertical mill for cement production line, and CHAENG not only produce vertical mill for customer from all over the world, but also can produce according to your demend.
