Components Introduction of the Cement Mill

It is known that cement mill is the key equipment used to re-crush the materials . This mill is widely used in cement, silicate products, new building materials, refractory materials, fertilizer, black and non-ferrous metal processing , glass ceramics production, and the other industries.

The mill components:

1. Cylinder
This machine is the horizontal cylinder rotating device, and
mainly composed of cylinder mill door, liner bolts, the most important failures
of the cylinder are bolt leakage gray mill gate leakage gray, barrel bending, in
view of the cement mill temperature , rarely occur the cylinder bending
phenomenon, but the cement grinding is relatively thin , cylinder bolts and mill
door drain gray phenomena often appear. To this end, we are required to arrange
the cylinder mill door fastening work at any time when the mill shuts down.

2. Liner
Liner is used to protect the cylinder,and avoid damage of the
long-term impact and friction cylinder,we can also adjust the motion state of
the material in mill. When checking, we mainlycheck the liner wear condition,
whether the liner bolts are loose fall or not to avoid liner's excessive wear,
because this wear can result the material changes in the state of motion and
reduce cylinder life.
3. Compartment plate
Compartment plate is mainly
composed of center circle compartment plate, stock guide cone, grate plate,
lifting plate, lining, compartment plate bracket, blind plate. When checking
,the main work is to check whether the compartment plate bolts loose, fall, each
grate is intact, grate seam is clogging the grate plate and blind plate
excessive wear, cracks compartment plate bracket, whether the impact of the
grate plate , string ball phenomenon or not.
4. Main bearing
Bear the mill
rotary part quality and impact of the grinding media , the mill support on the
main bearing through the hollow shaft , the bearing housing is equipped with
bearing cap, observation hole (observation of oil supply and the control shaft,
bushing functioning), the thermometer of the temperature measurement. The
bearing lubricant adopts hydrodynamic lubrication and hydrodynamic lubrication
these two methods, dynamic pressure use the low fuel supply, duo to the mill
speed is low, the oil film dynamic pressure formed is thin,can not reach the
effect of liquid friction and lubrication, so the hydrostatic lubrication is
adopted, specifically set of high-pressure oil pump for high-pressure oil to the
oil bag, rely on the pressure of the oil to form a thick film. In the normal
operation, the static pressure lubrication, hydrodynamic lubrication still work
automatically, when appears the static pressure problems, the dynamic pressure.
The general bearing liner allowed temperature does not exceed 70 °. if the
bush-burning phenomenon occurs, we must take the cooling method.
