Problems solved by technology

[0003] When the external high-pressure air sprays airflow to the crushing chamber through the high-pressure nozzle, the material is crushed after being repeatedly impacted and collided by the airflow. The crushed fine particle material enters the classification chamber with the upward airflow, and the fine particle enters the cyclone separator and collector along with the airflow. After collecting and completing the crushing process, the coarse particles return to the crushing chamber to continue impact crushing. The particles obtained by the traditional fluidized bed device are not uniform, and the structure is complex and inconvenient to operate.

Abstract

The invention discloses an airflow crushing device of a fluidized bed. The device comprises a supporting base and a body. A grading cavity, a crushing cavity, a raw material feed inlet, a raw material discharging port, a compressed air annular pipe and high-pressure nozzles are arranged on the body. The compressed air annular pipe surrounds the body of the airflow crushing device of the fluidized bed and is connected with the high-pressure nozzles of the airflow crushing device of the fluidized bed through a guide pipe. The airflow crushing device has the advantages of being short in crushing time, simple in structure, low in noise and free of vibration, and is low in energy consumption. Compared with airflow grinding of other types, energy can be saved by one third.

Description

technical field [0001] The invention relates to a material crushing device, in particular to a fluidized bed airflow crushing device. Background technique [0002] Fluidized bed jet milling is a device that uses high-speed airflow to achieve ultra-fine pulverization of dry materials. It is widely used in minerals, chemicals, electronics, pesticides and other fields. [0003] When the external high-pressure air sprays airflow to the crushing chamber through the high-pressure nozzle, the material is crushed after being repeatedly impacted and collided by the airflow. The crushed fine particle material enters the classification chamber with the upward airflow, and the fine particle enters the cyclone separator and collector along with the airflow. After collecting and completing the crushing process, the coarse particles return to the crushing chamber to continue impact crushing. The particles obtained by the traditional fluidized bed device are not uniform, and the structure i...
