Turbine Classifier and Higher Pressure Blower Pendulum Roller
Components of Pendulum Roller Grinding Mill
The four rotational rollers hung on the spider arm on the shaft of
the main unit go around the rings tightly because of the
centrifugal force. The raw material lifted up between the rollers
and rings is ground into powder. The pendulum roller grinding mill classifier consists of bearing
base, shell, cover, reducer base, shaft, vane wheel etc. There are
two places in the classifier needed to be lubricated: 1) the top
one and 2) the bottom one. Lubrication at the bottom can be done
after removing the plug.
The pendulum roller grinding mill blower blades move quickly around the shaft driven by the motor; and the
spinning fan blade makes the air go into the air-return box. The pendulum roller grinding mill reducer is composed of Shaft, Gear, Screw, Gear Shaft , Cover,
Casing etc. Screw is for pushing the lubricant into the gear
through the Gear Shaft. Oil Scale is for checking the oil level.
Pendulum roller grinding mill pipe system includes: double-cyclone
collector, dust collector, bent pipe, straight pipe etc. The whole
system works under negative pressure. There is a discharging valve
at the bottom of the cyclone collector, which separates the
positive pressure airflow from negative pressure airflow. Leaky
sealing will result in no-powder-dropping or lower production
Lifting and Unloading of Pendulum Roller Grinding Mill:
Put the steel wire through the lifting lug of grinding mill. In
order not to make the shaft, roller assembly and blade support
move, the closed coupling at the bottom of shaft should not touch
the land and be under stress. If the shaft, roller assembly and
blade support move up, please make them in the previous position.
Or there will be some damage to the equipment. When hoisting the
classifier, please put the steel wire through the lifting lug of
classifier. For the electric control cabinet, the hoisting position
is the hoop on the top. There should be a gasket between the steel
wire and the equipment. The equipment should be keep up, and
overturning is forbidden.
Working Principle of Pendulum Roller Grinding Mill:
The crushed raw material (less than 20mm or 30mm or 40mm) will be
loaded into the elevator and then to the feeding hopper. Conveyor
will deliver the crushed raw material into the roller grinding mill
grinding chamber. Driven by the reducer and transmission shaft, the
spider arm, roller assembly and shovels can rotate. In the grinding
mill chamber, the roller on the roller assembly will also move
centrifugally and the crushed raw material can be ground into
powder between roller and ring.
The ground powder will go up through the classifier with help of
high-pressure blower. And the coarse powder that cannot go through
the classifier falls down to the grinding chamber, which will be
reground between roller and ring. The qualified powder will be
collected in the cyclone or in the pulse jet collector.
Improved Performance of Pendulum Roller Grinding Mill
- Roller and Ring are made higher and the shovel is made larger to
increase the grinding contact surface and grinding force to
- Improved Reducer: the newly-designed reducer rotation can be
adjusted according to customer’s requirement to increase output.
- Improved Classifier: the turbine wheel use big blade to increase
the fineness control, classifying precision and air volume passing
- Bigger size cyclone to increase collecting efficiency.
- High-pressure blower: air pressure can be increased to make air
