Description
Vertical Roller Mill Working PrincipleÂ
Material through the feed tube fell on the center of grinding
plate, centrifugal force generated from the rotation of grinding
plate uniformly scatters and flattens the materials outwards the
surrounding area of grinding plate, to forms a certain thick layer
of materials bed, the material was crushed by number of rollers at
the same time. Driven by the continuous centrifugal force to keep
the materials moving to the outer edge of the grinding plate, the
materials off the grinding plate rising with the hot air which
enter from wind ring into the mill, through the mill shell into the
middle of the separator, in this course materials and hot gas do a
fully heat exchange, and the water quickly evaporates. Separator
controls the output size of finished product, greater than the
specified size are separated and fall back to the plate, while meet
the fineness requirements are brought through the separator into
the finished product warehouse.
Vertical mill Structural Features
1. Composite separator improves the efficiency of the powder.
2. With the function of automatic lifting and falling , can realize
no-load starting.
3. Welded type arc plate is used for sealing, it features simple
structure, reliable performance, well-sealed structure.
4. By means of the roller swing-out device, the grinding rollers
can be turned out of the mill, which is in favor of
maintenance.
5. The limit mechanism avoids the fiction and crash of metals
between grinding roller and grinding plate, increasing the rotating
stability and security.
6. Operating pressure of hydraulic system is low, can reduce the
leakage failure and the mill vibration , is good for operation and
management.
7. The centralized circulating oil lubrication is applied to the
grinding roller bearings, which ensures the bearing operate at
constant temperature and with pure oil, so that longer service life
is achieved.
