Reasons for low powder extraction rate of Slag Vertical Roller Mill

In the milling production, the powder extraction rate of the Slag Vertical Roller Mill is directly related to the production capacity of the equipment, which affects the economic benefits of the users. Therefore, when the Slag Vertical Roller Mill has a low powder extraction rate, we must promptly identify the cause and discharge the fault as soon as possible to ensure the working efficiency and quality of the Slag Vertical Roller Mill. Here, let’s take a look at the reasons and solutions for the low powder extraction rate of the Slag Vertical Roller Mill.

1. The speed of the spindle of the Slag Vertical Roller Mill is one of the reasons that affect the powder extraction rate of the Slag Vertical Roller Mill. In the Slag Vertical Roller Mill production, if the power of the equipment is insufficient, the transmission belt is too loose or the wear is serious, it is easy to cause the active bearing speed to be unstable or even decelerate, which will slow down the grinding speed of the material. The Slag Vertical Roller Mill has a low powder extraction rate.

Solution: Increase the dynamic power of the Slag Vertical Roller Mill, adjust or replace the belt.

2. The wear of the wearing parts is serious, resulting in low dusting rate of the Slag Vertical Roller Mill. Grinding of the material by the mill is a process of shoveling the material through a blade and cooperating with the grinding ring to gradually grind the material into powder. If the Slag Vertical Roller Mill’s scraper, grinding roller, grinding ring and other wearing parts are seriously worn, the blade will not be able to shovel the material well, and the Slag Vertical Roller Mill grinding ring will not perform a good grinding action. This results in a low rate of powder extraction in Slag Vertical Roller Mills.

Solution: Check the wearing condition of the wearing parts in time, and timely repair and replace the blade, grinding roller and grinding ring.

3, the pipeline is not well sealed, the air duct is blocked, and it also affects the powder extraction rate of the Slag Vertical Roller Mill. When the Slag Vertical Roller Mill is in operation, if the pipe sealing effect is not good, the dust will increase and the negative pressure will be imbalanced, which will lead to a decrease in the powder conveying rate. The Slag Vertical Roller Mill conveying air duct blockage directly leads to the powder not being able to be transported normally, thereby reducing the powder extraction rate of the Slag Vertical Roller Mill and even producing no powder.

Solution: Check the sealing condition of the equipment before working in the Slag Vertical Roller Mill. In the event of a blockage in the air duct, it is necessary to stop the material in the pipeline in time and restart the cutting.

4. The locker is not adjusted to the correct state. If the powder breaker of the Slag Vertical Roller Mill production line is not adjusted to the correct state, resulting in poor sealing of the equipment and powder suction, the powder extraction rate of the Slag Vertical Roller Mill will be greatly reduced.

Solution: When using the Slag Vertical Roller Mill, we must pay attention to ensure that the locker, return air valve, and other valves on the pipeline are in proper working condition.

Of course, the reason for the low powder extraction rate of the Slag Vertical Roller Mill is that in addition to the factors of the equipment itself, the performance characteristics of the material itself also affect the production capacity of the Slag Vertical Roller Mill, which requires us to use the Slag Vertical Roller Mill correctly. Ensure the efficiency of the equipment.
