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.
