Micropowder manufacturing machine

Abstract

The invention relates to a micropowder manufacturing machine. The micropowder manufacturing machine comprises a sealed outer cylinder, wherein a grinding inner cylinder is arranged in the sealed outer cylinder, and is of a cylindrical structure with a bottom opening, a reflux gap is formed between the outer wall of the grinding inner cylinder and the inner wall of the sealed outer cylinder, a crushing cylinder with a bottom opening is sheathed in the grinding inner cylinder, and a crushing gap is formed between the outer wall of the crushing cylinder and the inner wall of the grinding inner cylinder; a main driving shaft is arranged at the top part of the sealed outer cylinder, penetrates through the top part of the grinding inner cylinder and is fixedly connected with the top part of the crushing cylinder, a plurality of grinding rings are annularly arranged on the wall surface of the crushing cylinder in an array way, a plurality of material discharging holes are formed between the adjacent grinding rings on the wall surface of the crushing cylinder, the bottom part of the sealed outer cylinder is rotationally connected with a blast turbofan, and the blast turbofan extends into the crushing cylinder via the bottom opening of the crushing cylinder.

Description

technical field [0001] The invention relates to a micropowder manufacturing machine, which belongs to the field of micropowder manufacturing equipment. Background technique [0002] Traditional micropowder pulverizers generally include a feed port and a discharge port, and a crushing mechanism is connected between the feed port and the discharge port. Therefore, the crushing mode is a single-flow path, and it is necessary to repeatedly move the material from the discharge port. The final product can only be obtained after repeated crushing at the feeding port. The process is complicated, and the loss of materials due to dust is relatively large. Contents of the invention [0003] The technical problem to be solved by the present invention is: to overcome the technical problem of the open cycle of the micropowder pulverizer in the prior art and the technical problem of high material consumption, and to provide a micropowder manufacturing machine with a closed pulverization ...
