Treatment of airflow pulverizer blockage

Today, I will talk about how to handle the problem of jet mill. Ultrafine pulverizer is low, and all of the lifescas is used in high quality wear-resistant materials at home and abroad. It has long service life. A small amount of easy wear parts are made of special hard resistance, small size, light weight, easy to replace the accessories. After the airflow pulverizer is filtered, the pulverizing cavity is sprayed through the Raval nozzle, and the material is repeatedly collided, friction, shear and pulverized, and pulverized material in the intersection of the multi-shaped high-pressure airflow. Next, the rising airflow is moved to the hierarchical region, and the crude material is separated under the powerful centrifugal force generated by the high-speed rotation, the fine particles that meet the particle size requirements are collected by the grading wheel into the cyclone and the dust collector, and the crude particles drops to the pulverization. The district continues to smash. The ultrafine pulverizer is composed of silo, mechanical pulverizer, air blower, cyclone, vibrating screen, liquid nitrogen tank, etc., the deep-cooling pulverizer system is refined by liquid nitrogen as a cold source, and it is crushing at low temperatures by cooling. After the crushing state, enter the mechanical pulverizing cavity through the impeller high speed rotation, the material and the blade, the tooth disc, the material and the material are enrolled under the integrated effect of collision, shear, friction, etc., to achieve a crushing effect. It is well known that the product technology of the injection crusher has been widely recognized by the industry.

Our daily life has a lot of small crushers, Chinese medicine crushers, universal crushers, etc., sometimes there will be some troubles, sometimes it will block the opportunity, how should we deal with In fact, when the crusher is broken, it is a common fault. The main reason is surgery. Today, we will teach you some ways to solve the problem of blockage of the shredder.

1. The feed speed is too fast, the load is increased, causing blockage. In the feed, always pay attention to the deflection angle of the current table pointer. If the rated current is exceeded, the motor overload and long-term overload will burn the motor. In this case, the feed port should be reduced or closed, and the feed mode should be changed, and the feed amount is controlled by increasing the feed rate. There are two feeders, manual and automatic. The user should select the appropriate feeder according to the actual situation. Due to the high speed, load of the mill, the load fluctuates is large. Therefore, the current of the pulverizer is usually controlled at about 85% of the rated current.

2. If the exhaust pipe is blocked or blocked too fast, the mill exit will be blocked; if the delivery device is not suitable, the venting tube will be weakened or blocked. After discovering the fault, the export transportation equipment should be cleared, and the replacement is not replaced.The amount of charge makes the equipment normally.

3, the hammer is broken, aging, and the screen closed, the crushing material is too high, which will cause the pulverizer. Regularly update the damaged hammer, keep the grinder maintain a good working condition, and check the screen. The water content of the crushing material should be less than 14%, which not only improves production efficiency, but also causes the grinding machine to plug, improve the reliability of the mill.

These are methods for treating grinders. Machine failure is very common. Most importantly, we need to know how to solve the problem, which is a factor that makes the grinder use time. In addition, it is also important to maintain the machine.
