IMPACT-TYPE AIR CURRENT PULVERIZER AND PULVERIZATION OF RAW MATERIAL FOR POWDER

摘要

PURPOSE: To improve the efficiency of pulverizing toner or color resin for toner. ;CONSTITUTION: The subject impact-type air current pulverizer consists of a speed acceleration tube 3 for accelerating the speed of transport of raw material for powder using a high pressure air, a pulverization chamber 8 and an impact member 6 provided in the pulverization chamber at an opposite position to the speed acceleration tube outlet. In addition supply apertures 1 for raw material for powder are provided in the speed acceleration tube and a secondary air introduction aperture 10 is formed between the supply aperture for raw material for powder ad the speed acceleration tube outlet. Further, the technique to pulverize the raw material for powder is introduced.;COPYRIGHT: (C)1993,JPO&Japio
