Dolomite Grinding Mill

Why Is The Production Of Dolomite Grinding Mills Getting Lower And Lower?

The Dolomite Grinding Mill is a grinding equipment that integrates drying, grinding, powder selection and conveying. It is favored by users because of its small footprint. However, many people have reported that after using the equipment for a period of time, the output is not as good as before, which directly affects the economic benefits.

Factors Affecting The Output Of Dolomite Grinding Mills

1. Grinding Roller And Disc Liner Wear

When the Dolomite Grinding Mill is working, the grinding pressure is applied by the grinding roller, and the material is subjected to the action of pressing and shearing of the grinding roller and the grinding disc to achieve the purpose of grinding the material, so the wear of the grinding roller surface and the grinding disc surface liner is inevitable. . As the grinding time is prolonged, the wear of the lining plate will be more serious. The gap between the grinding roller and the grinding disc will become an inner small outer large or uneven shape, and the grinding efficiency will be greatly reduced, resulting in a significant drop in the output of the Dolomite Grinding Mill.

In this case, the wear of the lining should be checked regularly. When the grinding roller and the disc lining wear to a certain extent, it must be replaced in time to avoid the vibration or other problems affecting the Dolomite Grinding Mill operation due to the wear of the lining. . The wear of the lining plate should be checked and treated in time. The lining plate can be changed and the height of the retaining ring can be lowered to extend the service life of the lining.

2. Wear Of The Retaining Ring

The purpose of the wear ring is to allow the material to be fully milled on the disc. If the retaining ring is worn or dropped, the thickness of the material layer will be reduced, and the vibration of the Dolomite Grinding Mill will become larger. The coarse powder will not be fully ground and the grinding disc will be pulled out under the action of centrifugal force, which will increase the amount of returning. The total amount of grinding has also increased, which can only reduce the output of the Dolomite Grinding Mill, and the vibration is large, and it is easy to jump, which affects the operation of the Dolomite Grinding Mill. Therefore, it is necessary to check the retaining ring regularly and find out the problem in time.

3, The Wear Of The Spout Ring

The main function of the spout ring is to change the wind direction through the guide vanes to ensure that the airflow is spiraled upwards and the material is taken away. If the nozzle ring is worn or partially worn, the airflow will be disordered, and a stable swirling upward airflow will not be formed, and the wind speed will also be reduced. The material cannot be taken away in time, returning to the grinding disc or the bottom scraping chamber of the nozzle ring to increase the circulation amount. Affect the production of Dolomite Grinding Mills.

4, The Performance Of The Material

The hardness of the material to be milled is large. For example, the high silicon material has poor grindability. In order to achieve qualified raw materials, it is bound to prolong the grinding time of the material and increase the internal circulation of the grinding. The materials in the grinding can not be discharged in time, and only the production can be reduced.

The material size of the grinding material is too large, it will increase the number of grinding, the circulation amount increases, the pressure difference is high, it is difficult to grind, and it will also cause large vibration and unbalanced operation.

Therefore, according to the actual conditions of the raw materials of various manufacturers, according to the wearability and grain size of the materials, the operation of the Dolomite Grinding Mill is controlled to avoid affecting the output.

5, The System Leaks

The leakage of the Dolomite Grinding Mill body will inevitably result in a small pressure difference and insufficient wind speed. The powder cannot be taken away in time, affecting the output of the Dolomite Grinding Mill. In addition, other parts of the system will leak air, and the wind speed will decrease, which will cause the pipeline to accumulate. After the pipeline is accumulated, the ventilation area will become smaller, and the insufficient air volume will also affect the output of the Dolomite Grinding Mill. Therefore, it is necessary to check the air leakage problem of the processing system in time.

6, The Thickness Of The Layer

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 on the grinding roller liner and the grinding disc liner. The Dolomite Grinding Mill vibrates greatly, jumps easily, and also damages the liner, the tension bar, etc. Therefore, it is not possible to control the 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 production and affect the output of the Dolomite Grinding Mill.
