Abstract

The invention discloses airflow grinding equipment and a wall breaking method with the same for pollen pini. The airflow grinding equipment is characterized in that a circulating channel is formed by a fan (1), a circulating pipeline I (4), a circulating stop valve (6), a grading device (7), a grading device (8), an adjusting valve (9), an air inlet three-way part (11) and a circulating pipeline II (13). The airflow grinding equipment and the wall breaking method disclosed by the invention have the advantages that materials form fluidized state and flows circularly at high speed in the circulating channel, the fluidized materials are ground under the action of a fan impeller, a pipe wall and mutual collision; the equipment is simple in structure, high in grinding efficiency, low in energy consumption and large in yield.

Description

technical field [0001] The invention relates to a circulating air flow crushing device and a method for breaking the wall of pine pollen. Background technique [0002] The working principle of the existing jet mill is that the compressed air is sprayed at high speed through the nozzle into the crushing chamber pre-loaded with materials, and the materials are repeatedly collided, rubbed, and sheared at the intersection of multiple high-pressure airflows, and the crushed materials are crushed. Under the action of fan suction, it moves to the classification device with the upward airflow to separate the coarse and fine materials. The fine particles that meet the particle size requirements enter the collection device through the classification device to collect, and the coarse particles descend to the crushing area to continue crushing. The existing jet mill has a complex structure and consumes a large amount of compressed air. The current pine pollen wall breaking method is to...
