One of the reasons for clogging is that the feed rate is too fast and the load increases. Solution: Be careful when using the crusher. During the feeding process, be sure to pay attention to the large deflection angle of the ammeter pointer. If the current exceeds the rated current, it indicates that the motor is overloaded, which will cause the motor to burn out for a long time. When this happens, immediately reduce or close the feed door, or change the feed mode, and control the feed amount by increasing the feeder. There are two types of feeders, manual and automatic. Users should choose the appropriate feeder according to the actual situation. If the discharge pipe is bad or the feed is blocked too quickly, it will block the tuyere of the pulverizer. Improper cooperation with the conveying equipment will cause the wind in the discharge pipe to weaken or block after there is no wind. Solution: After the fault is identified, clean the discharge port, replace the unmatched conveying equipment, adjust the feeding amount, and ensure the normal operation of the equipment. Hammering, aging, closed sieve hole crushing, and excessive moisture content of crushed materials will block the crusher. Solution: Broken and severely aged hammers should be replaced regularly to keep the grinder in good working condition.

The traditional Chinese medicine ultrafine pulverizer adopts an air separation particle classification system. The crushing of materials and the classification of dust are installed in the same body, but the two operate independently. It has the characteristics of complete functions, compact structure, stable technical performance, low noise, high power consumption, high efficiency, beautiful appearance, flexible use, wide application range, no over-grinding, adjustable powder fineness, and simple maintenance. The device is composed of main engine, auxiliary engine, air collecting pipe and electric control device. The auxiliary machine is equipped with a cyclone dust collector and a filter bag dust collector, which are combined into one. Air separation and centrifugal shearing, no need for sieves or sieves, powder particles can be adjusted at will. After the material is crushed, it is conveyed to the outlet of the discharge valve through negative pressure to meet the product requirements. It is widely used in ultra-fine grinding in different fields of chemical industry, dyestuff, paint, medicine, food and other industries. Crushing and grading of materials are carried out in the same closed system. After dust removal, there is no pollution.
