What is the impact of the large water content of the raw material on the pulverization process of the jet mill
Jet mills are favored by many industries. Jet mills can pulverize raw materials into powder, which can increase its added value to a large extent. The jet mill is not suitable for all materials. When the equipment crushes the materials, the nature of the feed is very strict. One of the feeding properties is the moisture content. The moisture content will change under the influence of weather. One is too large and the other is too small. These two conditions have different effects on production. The following analysis is carried out for these two situations:
- Low moisture content
The jet mill is relatively easy to crush materials with low water content. Due to the low moisture content, material blockage is not easy to occur during production, and the production process is relatively smooth. Therefore, the efficiency of the jet mill is relatively high in this case, and it is also the best state of the jet mill.
- Large moisture content
When the moisture content is large, the jet mill is prone to sticking and blocking during the crushing process, which makes the crushing process abnormal. The pulverized powder is easy to stick around the grinding roller, grinding ring and liner. At this time, it will reduce the performance of the parts and reduce the production efficiency, and this situation will also cause the phenomenon of increased wear. In addition, when the moisture content is large, if the air volume of the blower in the mill is small, the animal material cannot be blown to make it float; if the air volume of the blower is increased, the unground materials may float together, and these unqualified powders will stick. On the analysis machine, when the circulating air flows to the air duct, the material will block the air duct, the grinding cavity cannot get good ventilation and heat dissipation, and the internal temperature rises, which reduces the working efficiency of the motor, which is very unfavorable for the production of the mill.
From the above situation, it can be concluded that a small moisture content is beneficial to the production of the mill, while a large moisture content will cause a decrease in the efficiency of the jet mill and an increase in wear. Therefore, in actual production, it is necessary to add The water content of the materials in the mill must be strictly controlled.
