Under the condition of long-term operation of the vertical pulverizer, the bearing will be heated, and the mutual friction between the components in the grinding room of the pulverizer will also cause the temperature rise to be relatively fast, especially in the outdoor with high temperature, so the heat dissipation system of the pulverizer is particularly important. We need to find out the reason for the temperature rise of the fuselage, and then solve the problem.
Friction and heat generation between ore materials: the fineness of the ore grinded by the pulverizer required by the customer is generally small, and the fineness of the material is required to be uniform, the vertical pulverizer can grind a lot of ores. Common ore fine grinding operations such as limestone and dolomite can be completed by ultra-fine vertical pulverizers. However, during the grinding of rocks, the collision between these stones will cause serious temperature rise of the vertical mill, so the heat dissipation system of the mill is very important. The heat dissipation system determines the stability of the machine operation and the service life of accessories to a certain extent.
Collision and heat generation between ore and body parts: as a common grinding mechanical equipment for ore, the vertical mill needs to repeatedly fine grind the ore to a certain extent. Of course, during the repeated fine grinding operation of the vertical mill, the internal temperature rise of the ultra-fine mill is relatively serious due to the impact of the parts of the ultra-fine mill and the ore and other materials. The casting parts of the vertical mill are composed of many alloy elements. Under the action of alloy elements, it is easy to cause the machine to run hot, or the motor rotor and the rotor speed of the mill are different, which will cause the bearing of the vertical mill to be hit by a certain load and generate heat.
Because the mill bearing bears a relatively large load, the wear of the bearing of the vertical mill is not small, therefore, the phenomenon of the mill bearing heating occurs. When users buy the ultra-fine mill, they should pay attention to the overall quality of the ultra-fine mill and check the heat dissipation system of the mill. It should also be noted that there are problems between the bearing cover and the bearing of the vertical mill, which requires stopping the machine to remove the bearing and repair the friction part.
