Its powder collection room adopts a fully enclosed soundproofing structure, which can effectively reduce working noise. The machine is equipped with a cooling device to lower the temperature and ensure smoother operation. The motor speed of this machine is 5000 revolutions per minute. This machine is made of Icr18Ni9Ti stainless steel material, which has strong wear and corrosion resistance characteristics and is suitable for processing high-grade and corrosive materials. This machine adopts the impact crushing method. After the material enters the crushing chamber, it is impacted by six high-speed rotating movable hammers, and is crushed by the collision between the gear ring and the material. With the help of airflow, the crushed material enters the powder bag through the sieve holes without leaving any residue. It has the advantages of high efficiency, low noise, reliable work performance and product quality, safe operation, low drug hygiene and loss.

6、 Common troubleshooting solutions

TJF crusher is blocked

TJF crusher blockage is one of the common faults in the use of crushers, which may be caused by problems in the design of the equipment, but more often due to improper use and operation.

(a) The feeding speed is too fast, causing an increase in load and resulting in blockage. During the feeding process, always pay attention to the large deflection angle of the ammeter pointer. If it exceeds the rated current, it indicates that the motor is overloaded. Prolonged overload may burn out the motor. If this situation occurs, the feeding door should be immediately reduced or closed, and the feeding method can also be changed by increasing the feeder to control the feeding amount. There are two types of feeders: manual and automatic. Users should choose the appropriate feeder according to their actual situation. Due to the high speed, large load, and strong fluctuation of the load of TJF crusher. So, the current during the operation of the crusher is generally controlled at around 85% of the rated current.

(b) If the discharge pipeline is not smooth or blocked and the feeding is too fast, it will cause the TJF crusher air outlet to be blocked; Improper matching with conveying equipment can result in weakened air flow or blockage of the discharge pipeline when there is no air. After identifying the malfunction, the mismatched conveying equipment should be cleared first, and the feeding amount should be adjusted to ensure the normal operation of the equipment.

(c) Hammer fragments, aging, closed and broken sieve holes, and high moisture content in crushed materials can all cause blockage of the TJF crusher. Broken and severely aged hammer blades should be regularly updated to maintain the good working condition of the crusher, and the sieve should be checked regularly. The moisture content of the crushed material should be less than 14%. This can improve production efficiency and prevent blockage of the TJF crusher, enhancing the reliability of the crusher's operation.
