The Cryogenic Pulverizer is widely used in medicine,chemical and food indutries, it is especially suitable for pulverizing heat sensitive materi-als,rubber, resin,plastic,medicine. plants and animals which are rough and difficult to pulverize under room temperature. Working Method The machine is composed of silo, crushing chamber, induced draft fan, cyclone separator and liquid nitrogen tank. The system uses liquid nitrogen as a cold source. After the pulverized material is cooled and friable at low temperature, it enters the pulver izer chamber and the blades rotates at high speed. The material and the blades, the toothed disc, and the material and the material under the combined effects of repeated impact, collision, shearing, and friction, the pulverization effect is achieved. The pulverized material is classified by an air flow classifier and collected: the material that has not reached the fineness requirement is returned to the silo to continue pulverization, and most of the cold air is returned to the silo for recycling. Characteristics In the process of material pulverization, the cooling system forms a closed loop to make full use of energy and save energy. The temperature of the cooling source for pulverization can reach minus 196 degrees celsius. According to the embrittlement point temperature of the material, the temperature can be adjusted during the pulverization process, and the preferred pulverization temperature is selected to reduce the energy consumption.
