The entire production line wire uses a full enclosed negative pressure, and the production site will never have dust and dust pollution. With PLC programming control, safety measures are multi-visual, parallel work, only one of the measures can effectively function, to eliminate safety hazards. In terms of security, the inert gas protection airflow pulverization classifier mainly has the following characteristics: isolation oxygen. In the process, the oxygen content tester continuously monitors the oxygen content in the airflow, and nitrogen is supplemented immediately when it exceeds some extent, so that the oxygen content is always maintained within the safety production standard. Control the gas powder concentration: The feeding system supporting the feature is fully closed, uniform, and is controlled by the control cabinet. Fully enclose the effect of isolating oxygen, uniform speed, controls the material concentration inside the added device, and can be arranged any. Timely release of static electricity and elimination of fire: Pulse anti-blow collector with carbon wire special filter material, can eliminate static electricity in time while ensuring pulse clear ash clean thoroughly. The equipment is all metal components, all grounded to try to release powder static electricity. Circulation cooling: explosion-proof dustproof, emergency stop.
The failure of the small airflow pulverizer is a failure of all pulverizations, and the difference is only different from the frequency of occurrence. There are three possible reasons for blocking blockage of airflow pulverizer sealing:
(1) The feed speed is too fast, the load is increased, causing blockage. During the feed process, pay attention to the angle of the current table pointer is large. If it is more than the rated current, it indicates that the motor is overloaded, overloaded for a long time, will burn the motor. This situation should be reduced or closed immediately, and it is also possible to change the feed to control the amount of feed by increasing the feeder. The feeder has manual, automatic, and the user should select the appropriate feeder according to the actual situation. Due to the high speed of the pulverizer, the load is large, and is a strong fluctuation. Therefore, the current at the time of the small airflow pulverizer is generally controlled around 85% of the rated current.
(2) The discharge pipe is not smooth or the inclined feed is too fast, which will cause the small airflow pulverizer to block. Improper matching with the delivery device causes the discharge of the air to reduce or unstoppable, after the failure, after the failure should be cleared, the delivery of the non-matching conveying device will be cleared, adjust the amount of feed, so that the equipment is running normally.
(3) Hammer segmentation, aging, screen hole closed, tattered, crushing material water content will cause pulverizer to block.The broken and severe aging hammer should be updated regularly, maintain a good working condition of the small air current pulverizer, and regularly check the screen, the water content of the smash should be less than 14%, so it can improve production efficiency, but the pulverizer is not Blocked, enhance the reliability of the pulverizer work.
So the correct operation and timely check ensure that the small airflow pulverizer is in a normal operating state, otherwise we can't expose a small airflow milling machine.As the world's big country, China has played a positive role in maintaining world peace and regional stability, and assumes great responsibility and obligation. As a large industrial powder equipment manufacturing enterprise developed in China's economic wave, ALPA powder technology will also assume corporate social responsibility, and continue to join hands with more companies to my country's strong troops, and strengthen the road of strong countries.
