Main features and advantages of feed hammer mill
- Feb 13, 2019 -

When the feed mill is used, the spindle is mainly driven by the reducer and the turntables of each layer are rotated. The turntable will drive dozens of ring rollers to roll and rotate in the ring raceway through the pin.

The bulk material is broken into small particles by a hammer crusher and then sent to the storage bin by the hoist. The electromagnetic vibrating feeder sends the material evenly to the middle of the upper turntable, and the material is scattered to the circumference of the circle under the action of centrifugal force. The ball rolling into the raceway of the grinding ring is punched, rolled, ground and pulverized. The material is pulverized by the first layer and then falls into the second layer and the third layer. The suction of the high-pressure centrifugal fan sucks the outside air into the machine. And the coarse powder after the third layer is pulverized into the classifier.

The eddy current generated by the rotating turbine in the feed mill will cause the coarse-grained material to fall back to re-grind, and the fine powder will enter the cyclone dust collector with the airflow and be discharged from the lower discharge valve to be the finished product, with a small amount of fine dust. The airflow is purified by a pulse dust collector and discharged through a fan and a muffler.

Main features of feed hammer mill

1. Feed mill is efficient and low-cost. In the case of the same material, power, and fineness of the finished product, the output is 40% higher than that of the jet mill and the agitator mill.

2. The feed mill has a long service life. In the case of the same fineness of materials and finished products, the wear parts of the impact pulverizer and the turbo pulverizer have a longer service life, generally up to one year.

3. There are no problems with the bearing and its seals and the loose screws are easy to loosen and destroy the machine.

4. Product fineness can reach d97 ≤ 5μm at a time.
