Closed loop airflow pulverizing system

Abstract

The invention discloses a closed loop airflow pulverizing system, comprising a pulverizing classifying device for pulverizing materials, a feeding device for feeding materials, a powder collecting device for collecting finished powder, and a gas compressor for circulating gas medium, wherein a gas outlet pipe of the gas compressor is connected to the pulverizing classifying device, and a gas inletpipe of the gas compressor is connected to an exhaust port of the powder collecting device; the gas compressor supplies compressed inert gas or pure air, and the inert gas includes nitrogen, argon and the like. According to the invention, the whole process of pulverization is carried out in a closed manner, and ultrafine pulverization is completedby selecting a suitable gas medium according to the physical characteristics of materials and the demands of users, thereby avoiding pollution caused by the diffusion of powder into the atmosphere, preventing powder pollution caused by the interference of impurities in the air, and avoiding the danger of explosion caused by sufficient convergence of flammable powder and oxygen.

Description

technical field [0001] The invention relates to a material crushing system, in particular to a closed loop air flow crushing system. Background technique [0002] Now powder metallurgy industry, chemical industry, pharmaceutical industry and other raw materials are inseparable from crushing equipment. Inflammable and explosive raw materials, easily oxidized raw materials, etc. need to be isolated from oxygen and moisture when crushing. The quality of production. Although the crushing production process is one of the processes in the entire raw material production process, the quality assurance of raw material crushing production runs through the entire production process, especially flammable and explosive raw materials and easily oxidized raw materials. cause waste of raw materials. However, traditional crushing equipment is difficult to solve this problem, the control of flammability and explosion, the control of easy oxidation, the control of air moisture, and the effec...
