Process Optimization Analysis on Vibration and Noise of Tooth-claw-type Pulverizer

Through the analysis on the tooth-claw-type pulverizer manufacturing and working process, the main reason to produce vibration and noise of the tooth-claw-type pulverizer is summarized using the fishbone diagram. It＇s pointed out that the optimization measures, such as improving dynamic and static balance of the rotating parts of the pulverizer, reducing machine vibration by reasonable use of rubber mat, optimization of assembly technique, improving the product structure and the operating skills of workers, and purchasing high precision equipment, can actively reduce the noise and vibration of the pulverizer. Through the noise decibel value statistical comparison for the tooth-claw-type pulverizer respectively before and after optimization at no-load and load conditions with the noise test apparatus, the validity of the optimization measures is proved, and the oualitv of the tooth-claw-type pulverizer is improved.
