Fluidized-bed airflow pulverizing system

Abstract

The invention discloses a fluidized-bed airflow pulverizing system. The fluidized-bed airflow pulverizing system comprises an air compressor, an air storage tank, an air freeze dryer, a fluidized-bed airflow pulverizer, a cyclone separator, a catcher and an induced draft fan which are connected through pipelines. The fluidized-bed airflow pulverizer comprises nozzles, a pulverizing chamber, a raw material inlet, a raw material outlet and a classification chamber. The fluidized-bed airflow pulverizing system has the beneficial effects of being short in pulverizing time, simple in structure, convenient to operate and maintain, small in occupied area and low in energy consumption.

Description

technical field [0001] The invention relates to equipment for superfine pulverization of materials, in particular to a fluidized bed jet pulverization system. Background technique [0002] The fluidized bed airflow pulverization system is a device that uses high-speed airflow to achieve ultra-fine pulverization of dry materials. [0003] Widely used in minerals, chemicals, electronics, pesticides and other fields. [0004] When the external high-pressure air is cooled, the high-pressure nozzle outside the crushing room sprays airflow to the crushing chamber. The material is repeatedly impacted by the airflow and crushed after collision. Under the centrifugal force generated by the grading rotor and the centripetal force generated by the viscosity of the airflow, when the centrifugal force on the particles is greater than the centripetal force, the coarse particles return to the crushing chamber to continue impacting and crushing, and the fine particles enter the cyclone sep...
