Abstract：Structural design scheme of “pin”(品) type was proposed by reasonably integrating and innovating the working principle of impact type ultra-fine grinder and jet mill.According to structural needs and working conditions,the corresponding wear-resistant materials were tested to determine the optimal pairing and operation parameters.The structural design of the new collision type ultra-fine powder grinding equipment prototype was accomplished.PLC technology was adopted to realize real-time control of the system.The automatic control system design of the equipment was completed.Industrial continuously running test was conducted by forming system with purchased grading machine,cartridge-type dust collector,fans and other equipment.The results show that the grinder and the corollary equipment can reach design requirements and completely satisfy the need of industrial production.
