摘要： A pneumatic pulverizer comprises an accelerating pipe for conveying and accelerating powder by a high pressure gas, a pulverizing chamber and an impinging member which pulverizes the powder jetted out from the accelerating pipe through impinging force. The impinging member is provided in the pulverizing chamber as opposed to the accelerating pipe outlet and the impinging member has an impinging surface with a tip portion having a conical shape with an apex angle of 110.degree. to 175.degree.. In this way, powder is pulverized at the impinging surface of the impinging member and dispersed substantially in the entire circumferential direction after impinging and the powder dispersed may impinge secondarily on the wall of the pulverizing chamber.

摘要： A pneumatic impact pulverizer is disclosed which has a nozzle for feeding high-pressure gas, a tube for transporting and accelerating a pulverizing material, a pulverization chamber, and an impact member for pulverizing the material. The impact member is opposed to an outlet of the accelerating tube and has at least a first impact face projecting toward the accelerating tube side and a second impact face sloped toward the downstream side. The pulverization chamber has at least a first sidewall positioned on the side more upstream than the outermost edge of the second impact face and a second sidewall positioned on the downstream side of the first sidewall. The pulverization chamber is enlarged at its part on the side more upstream than the outermost edge of the second impact face so that the cross-sectional area of the inside of the chamber at that part is larger than that of the inside of the chamber corresponding to the outermost edge of the second impact face. The tip of the first impact face is positioned on the side more upstream than the downstream side edge of the first sidewall. The pulverization can be conducted in a very high efficiency with the pulverizer. Also, a process for producing a toner for developing electrostatic images using the pulverizer is disclosed.
