The cement grinding production process mainly includes the grinding system, the grinding system, the pneumatic conveying system, the finished product storage system and other auxiliary systems. These need to be based on actual production requirements in the cement grinding process. Configuration, because different equipment can work together to produce finished cement with different granularities, and the application range of cement with different particle sizes is different.
The various equipments required in the cement grinding production process must be selected according to the needs of different models, and these different models have different performances in the production line due to the difference in performance. So the equipment will be different in price.
Ultra-fine grinding equipment is the main equipment in the cement production line. There are various types of equipment, each of which has many different models, such as the main motor and electric motor equipped in the 130X reinforced cement mill equipment. The production effects brought by the different models are also different.

The dolomite milling machinery is mainly used to produce milling powder. The equipment will generate friction between various parts during the production process, which has certain damage to the various parts of the equipment.
Affecting the service life of the equipment, in addition to this friction, if the operation of the staff is not correct, the equipment will be damaged during the production process. In order to solve this problem, here is a description of the dolomite milling machinery. Operation and maintenance methods.
The first is the operation mode of the equipment. Generally speaking, each ore production equipment has a relatively standardized operation process, and it is only necessary to operate according to this operation mode during production.
The operation of the dolomite milling equipment generally ensures that the doors and windows of the equipment are tight, and there is no residual material inside the equipment, and the initially broken materials need to be sent to the storage bin for storage to ensure that the equipment can be started after these points.

At present, the development of the cement plant industry is also not optimistic. First of all, the production capacity continues to grow, the market competition is increasingly fierce, and it is extremely urgent for cement plant production enterprises to reduce production costs. At the same time, various construction projects put forward higher requirements for cement plant quality.
This has brought tremendous development pressure to cement plant companies. Secondly, the cement plant industry has always been regarded as one of the industries with serious environmental pollution. The increasingly serious resource and environmental problems have also made the energy saving and environmental protection pressure of the cement plant industry not to be ignored.
Therefore, in the future, the cement plant industry must find ways to reduce production costs, improve product quality and production efficiency, and adopt a development mode of energy conservation and emission reduction. These need to continuously improve the cement plant production technology, and adopt a new type of crusher with high efficiency, energy saving and environmental protection is an effective method. While improving production efficiency and reducing production costs, the quality of the products is guaranteed. More importantly, the new crushers can minimize environmental pollution and reduce resource waste during the production process.

In order to reduce the failure of the marble grinding machine in the production process, the newly purchased equipment will be tested after the installation, so that the equipment itself and the installation process may be faulty. This is the purpose of the test operation. Let me introduce what the correct operation of the test run is.
The first is the no-load operation. When the material is not added, run the marble grinding machine machine. Then observe whether the screws and other parts are loose, the wire connection is normal, and the wire needs to be protected from being pressed. Otherwise It will cause line problems. It is also necessary to pay attention to the presence of noise and other abnormalities. If not, the no-load operation takes 2 to 4 hours, so that the possible faults can be fully observed. During the operation, pay attention to whether the bearings of the marble grinding machine are Will be hot, etc., these will be carried out without problems after the load;
The second is the inspection of the marble grinding machine on-load operation. It is to add materials to the equipment and then make it run. In this process, besides paying attention to whether the screws, rotors, etc. are loose, pay attention to the order of starting the machine to prevent improper start-up. The damage caused by the test machine is usually 8 to 12 hours. The problem to be paid during the operation is whether the bearing and other components have faults. The sequence of the shutdown after the end of the operation cannot be wrong.

In addition to the above factors, there are still many factors affecting the vertical mill output. For example, the mixture structure leads to material segregation, air volume control, hot air temperature control, batching control, etc., which will affect the vertical mill output. In actual production, it should be analyzed according to the specific conditions of the factory.
After the material is fed into the grinding disc, a certain layer is formed. When the thickness of the layer reaches a certain thickness, the grinding roller starts to grind. If the material layer is too thin, the grinding stress is too concentrated, and the grinding ability is reduced, which will inevitably lead to impact of the grinding roller liner and the grinding disc liner.
The grinding machine has large vibration, easy to jump, and will damage the liner, the tension rod, etc. Can not be controlled by thin layer. If the thickness of the material layer is too thick, the grinding force will be converted into lateral stress, and the sliding shear will be formed between the materials. The slump of the material bed will increase, the milling efficiency will decrease, and the vibration will be large.
The material will not be timely. Grinding and extruding the grinding disc, falling to the spout ring, increasing the circulation amount, the pressure difference is large, the material can not be ground away in time, forming a vicious circle, which can only reduce the production operation and affect the mill output.
The thickness of the layer is generally controlled to be about 50-80 mm. The principle is that the material fed into the mill should be ground in time and flow to the next process in time. The pressure difference of the system should not be too high to ensure that the vibration is within a reasonable range.
