how is a screen of hammer mill

   how is a screen of hammer mill? The screen of the SFSP56*36 water drop hammer mill is made of punched steel sheet and heat treated. When the screen is worn or penetrated by foreign objects, if the damaged area is not large, it can be repaired by riveting or soldering; if the area is damaged, it should be replaced with a new one. When installing the screen, the burr side of the screen hole should face inward and the smooth side outward, and the screen and the screen frame should be tightly fitted. The clogging of the feed crusher screen is a common failure in the use of the crusher. In different environments, the cause of this phenomenon will be different. We only need to find the root cause from the following several possible conditions.

  1. Feed material feed rate is too fast

  how is a screen of hammer mill? In the process of feeding feed ingredients, 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. If it is overloaded for a long time, it will burn out the motor. In this case, the feeding method should be changed, and the user should select a suitable feeder according to the actual situation. Due to the high speed of the 9FQ hammer mill crusher, the load is large, and the fluctuation of the load is strong. Therefore, the current when the crusher works is generally controlled at about 85% of the rated current.

  2. Hammer and screen problems

  how is a screen of hammer mill? Hammer fragments, large abrasion, screen holes are closed and broken, and the crushed material with too high moisture content will cause the crusher to block the screen. Broken and severely worn hammers should be regularly updated to keep the crusher in good working condition, and the screens should be checked regularly.

  3. The negative pressure in the crushing room is not enough

  how is a screen of hammer mill? There are many reasons for blocking the screen due to the problem of the wind network system. Ventilation, pulse jet pressure is too low, the fan selection department is reasonable, the pipeline is too long, the wind network pipeline leaks, etc. should be eliminated one by one to make adjustments and adjustments, and the daily maintenance of pulse bag inspection, cleaning or replacement, Ensure that the SFSP968*40 water drop hammer mill is operating normally.

  4. Material issues

  How is a screen of hammer mill? The moisture content of the crushed material should be less than 13%, which can improve production efficiency, prevent the crusher from blocking the screen, and enhance the reliability of the crusher work.
