Abstract

The invention discloses an efficient airflow crusher. The efficient airflow crusher comprises a crushing cavity; a feed port is formed in one side of the crushing cavity; a discharge port is formed inthe top of the crushing cavity; the cross section of the crushing cavity is circular; a spray blowing pipe 1 is arranged at the bottom of the crushing cavity; multiple spray blowing pipes 2 are arranged on the side wall of the crushing cavity; the spray blowing pipes 2 are positioned above the feed port; the spray blowing pipes 2 are the same in height, and are synchronously inclined clockwise oranticlockwise along the inner wall periphery of the crushing cavity; a conical transition part is arranged at the upper part of the crushing cavity; and the discharge port is positioned at the top end of the transition part. The efficient airflow crusher can prominently improve the material crushing effect, and improves the production efficiency.

Description

technical field [0001] The patent of the present invention relates to the field of mechanical processing, in particular to a high-efficiency jet mill. Background technique [0002] Jet mill is a kind of crushing machine with wide application range, which is widely used in biomedicine, metal powder preparation and other industries. The principle of the jet mill is: after the material enters the crushing chamber through the feeding system, the high-speed airflow of the crushing chamber impacts and repeatedly collides, rubs and shears against the inner wall of the crushing chamber, thereby turning into smaller particles. The raw material moves with the updraft under the action of the wind force. During the movement, the materials with different particle sizes are separated through the classification chamber, the fine particles are collected, and the coarse particles descend to the crushing chamber for further crushing. The existing jet mill has complex structure and is not eas...
