Maintenance point of air current pulverizer

For the maintenance attention of the airflow pulverizer, Xiaobian said his own opinion, I hope to give you some reference. 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. 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. 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. What kind of airflow pulverizer is a reliable product or service, many people feel confused with this large airflow pulverizer.

The maintenance of the ultrafine pulverizer is as follows:

1. During the production process, the temperature rise of the bearing must be checked regularly. When the temperature rises above 50 ° C, the cause should be checked and the fault is excluded.

2. When the new machine is running, the transmission belt is easy to stretch, and the tightness of the belt should be adjusted to ensure the life of the belt.

3, regularly check the lids to ensure that production, production quality is timely.

4. Negative the blade and bushing wear. When wear, the productivity is lowered and the grain is thick. 5. Main engines and gradient flow bearing fat lubricates, 2 special greases, 265-295 degrees.

6. The replacement period of the bearing is 2000 hours. Grease is filled with 1/2 (upper test) or 3/4 (below test) in the bearing chamber, so we cannot add too much grease. Otherwise, the bearing temperature is too high.

The spiral feeder is 4,000 hours, plus ordinary calcium based grease.

8. On the output shaft E, the wheel E is avoided, and the heavy hammer impact is avoided.

9. Turn the handle wheel handle is strictly prohibited when parking.

10. The lubricating oil used in this regulator uses N32 alkaline high-zinc anti-milling hydraulic oil. The reducer is made of 401 common lubricants. It cannot be replaced by other machines.

11. After 3000 hours, the new oil should be replaced, then the oil is used for the second time after 500 hours, then replace it for 1000 hours.
