In the grinding operation of the material in the pulverizer, because the feed is a block material and the discharge is a powdery material, two failures may often occur. It may be that these issues are very slight, but not being solved in a timely manner in the right way may result in larger or more complex problems. Therefore, it is very necessary to solve any large or small problems in the milling process in time. Where the blockage of the air duct is not a big problem, but the problem is very serious. Let's take a look at what causes the two reasons for the blocking of the air duct through which the mill equipment transports the finished material, and for these reasons, There are no reasonable preventive measures and more important solutions. We hereby choose an
ultrafine mill as an example to explain in detail so that you have two specific impressions and solutions. I hope to help you by reading this article.
When using an ultra-fine mill to grind chunks of material, the mass of material, after being crushed and ground by means of grinding rollers and grinding rings, turns into a powdered material. Then, the powder is selected by the fan, and the selected material will enter the transmission pipeline and then be discharged from the discharge port. The phenomenon of blockage mentioned here is the blockage of the air duct of the fan. The consequence is that the wind becomes smaller and the efficiency of powder selection is seriously reduced. If the equipment is continuously fed, it will cause a great burden on the equipment and then an overload phenomenon will occur. Causes the machine to stop, or to damage the machine or other auxiliary equipment, such as the electric control cabinet, although the problem is not big, but the result is quite serious.
Then we know that in the grinding production process, it is inevitable that there will be two faults and problems. Then what is the cause of the two failures of the air duct jamming, and the key is how to solve these two faults. Below, we analyze the specific reasons and solutions for these failures.
We have seen the principle of the second mill of the mill. The principle of the mill of the superfine mill is basically the same as that of the mill. It is also the mill roll and the mill ring for rolling, the classifier for the classifier, and then the collector. The device collects the finished powder and discharges it from the discharge port. In the process of powder selection, the main option is to use a blower to conduct air separation, and if the air duct is blocked, the wind power will be reduced. These are basically the same as the general principles of the mill, so the superfine mill was selected as a specific case for analysis. There are many reasons for the blocking of the air duct. Two common problems are: 1. The humidity of the material is too large; 2. The feeding is too fast. Let's analyze in detail the following two reasons why these two reasons will cause the air duct to be blocked?
If the humidity of the material is too high, the powdered material after grinding will adhere to the wall of the air duct. This will cause the wind force of the air duct to decrease, and more and more powders will adhere, resulting in blockage of the air duct. The other two reasons are that the feed is too fast and exceeds the processing capacity of the ultra-fine mill. Therefore, a large number of powders that do not meet the fineness gather in the air duct, the efficiency of powder separation is reduced, and the powder extraction rate is also reduced. Operators find out that Slower powders may be mistaken for slower feeds and faster feeds. This leads to a vicious cycle, which then causes the fans to become clogged and the equipment to shutdown. Well, when you see here, you may know how to avoid such a situation, but you will also ask: If such a situation occurs, the air duct is blocked. What should I do? How to clear the air duct? We are not in a hurry. We will conduct detailed introduction in the next two articles. How to clear the air separator of the separator?
