Nowadays, mining equipment has a wide range of models and types, and the utilization value of ore resources is very high. The utilization and processing of ore is indispensable to the processing of mining machinery and equipment such as ore mills. Then, during the use of the machine, the machine with a long time will have parts  wear problem.
 
With the development of emerging nanotechnology and the rapid development of the powder industry, there is also room for improvement of the powder mill, because with the continuous improvement of the technical level, the requirements for powder will also increase, so the milling equipment will follow Make corresponding adjustments to enhance the quality and efficiency of the produced materials, and there is still a large room for appreciation in the mill. CLIRIK ultra-fine mills have high-quality output, and the efficiency is calculated based on the output of processed materials. In addition, the technology of the equipment itself is a guarantee for the powder. CLUM is a high-performance ultra-fine mill equipment.
 

Reasons for bending deformation of roller shaft:

If the bending and deformation of the grinding roller shaft occurs during the operation of the bentonite mill, the normal operation of the grinding equipment cannot be guaranteed. The main reason: each type of bentonite grinding equipment has different requirements for the feed particle size. When the feed size is too large, the bentonite material will have a relatively large number of impacts with the main shaft as the mill rotates. More. In this way, it will cause deformation of the grinding roller shaft of the bentonite mill. Therefore, when we use the grinding equipment, we must pay attention to the control of the feed particle size, so as not to affect the grinding roller shaft; some users in order to greatly increase the processing output, and the bentonite mill is overloaded for a long time. This greatly enhances the pressure of each component during the operation of the mill, which intensifies the wear of the roller shaft and gradually leads to its bending and deformation. Therefore, maintaining the correct operation method and avoiding long-term overloading of the bentonite mill is an important factor in preventing the deformation of the roller shaft; because the bentonite mill is generally produced in the open air, the ground material contains a certain amount of moisture. This will inevitably cause the equipment to rust after being used for a long time. If we can not deal with the rust of these roller shafts in time, it will greatly reduce the working intensity of the equipment and even cause the mill to run unsteadily. It will also affect the quality of the material.
 
The time of the milling equipment will be lost to a different degree, so it is inevitable for the long-term use of ore milling.

 

What should I pay attention to when equipment parts are deformed?

Common milling equipment includes Raymond mill, high-pressure suspension roller mill, superfine mill, vertical mill and other milling equipment. The ore mill solves the problem of ore raw material processing, and then after the material processing time is long, the ore equipment parts are deformed. This is disadvantageous to the mill itself, and it affects the production efficiency while the milling machine is abnormal. Therefore, understanding the causes of the deformation of the parts of the ore mill, avoiding or correct prevention is the best operation of the ore mill, producing industrial raw materials and bringing stable and considerable benefits to users.
 
When the working stress generated by the external load exceeds the yield limit of the material of the mill part, it will cause permanent deformation of the mill part; the temperature rises, the atomic thermal vibration of the metal material increases, and the critical shear resistance decreases. Slip deformation occurs, which lowers the yield limit of the material; or the parts of the mill are heated unevenly, and the temperature difference is large everywhere, which generates large thermal stress and causes deformation; residual internal stress. In the process of blank manufacturing and cutting of the parts of the mill, residual internal stresses will be generated, which will affect the static strength and dimensional stability of the parts of the mill. This not only reduces the elastic limit of the mill parts, but also produces plastic deformation that reduces the internal stress of the ore mill; internal defects of the material. It is worth pointing out that the deformation of the parts of the mill is not necessarily caused by a single factor. It is often the result of the combined effect of several reasons and the accumulation of multiple deformations.
 
In order to prevent the deformation of the parts of the mill, it is necessary to start from many aspects, and to improve in the process, machine operation specifications and maintenance treatment to avoid or eliminate the above possible situations, and also to strengthen the transformation of the vulnerable parts. , Continuously extend the durability of parts.

 

What should I do if the room temperature of the pulverizer is too high?

The reason why the temperature of the grinding chamber rises is that after a long time use of the mill, the sealing condition of the equipment will continue to decrease, causing leakage of lubricating grease, which not only increases the temperature of the bearing, but also reduces the flexibility of operation Therefore, Shanghai Shibang recommends that users take necessary measures to prevent excessive temperature rise in the grinding chamber of the mill.
 
The specific measures are as follows:
Pay attention to the working conditions of the lubrication points of the mill, such as bearings, grinding rollers, etc., and regularly quantify the lubrication parts to ensure a good working environment for each part of the equipment, increase the flexibility of the operation of each part, and reduce the contact surface. The frictional force between them extends the service life of the equipment, thus avoiding the problem of excessively high temperature in the grinding chamber. According to the working conditions, the ventilation of the grinding chamber can be adjusted appropriately, that is, the ventilation ducts are opened, so that the external airflow and the airflow in the grinding chamber are convective, so that the temperature in the grinding chamber is slowly lowered, and the equipment avoids excessively high grinding room temperature.
