Problems solved by technology

[0002] There are many ways to pulverize ultrafine materials. Existing equipment such as alternating mills, etc., but the use of airflow to pulverize materials is also often used. Chinese patent application number 201420732480.6 discloses a jet pulverizer, which uses gas to drive materials. The material is crushed by colliding with the cutter, but for ultra-fine materials, the cutting edge of the cutter cannot reach the diameter of the material, so the fineness of the crushing is not enough

Abstract

The invention discloses an ultramicro material grinder which comprises a left nozzle and a right nozzle. An impact cavity is arranged between the left nozzle and the right nozzle; a feed inlet is formed between the left nozzle and the impact cavity; the impact cavity communicates with an upper guiding pipe and a lower guiding pipe; the upper guiding pipe and the lower guiding pipe communicate witha classifying cavity; the classifying cavity is in an annular shape; screen holes are formed in the inner side wall; triangular cutters are symmetrically arranged on a cavity wall of the classifyingcavity; the inner diameter of the upper guiding pipe is larger than the inner diameter of the lower guiding pipe; and the length of the upper guiding pipe is smaller than the inner diameter of the lower guiding pipe. The ultramicro material grinder provided by the invention has the advantages that mutual friction and collision between materials are increased, and a grinding effect is good.

Description

technical field [0001] The invention relates to the field of machinery, in particular to a pulverizer. Background technique [0002] There are many ways to pulverize ultrafine materials. Existing equipment such as alternating mills, etc., but the use of airflow to pulverize materials is also often used. Chinese patent application number 201420732480.6 discloses a jet pulverizer, which uses gas to drive materials. The material is crushed by colliding with the cutter, but for ultra-fine materials, the cutting edge of the cutter cannot reach the diameter of the material, so the fineness of the crushing is not enough. Contents of the invention [0003] In order to solve the above-mentioned technical problems, the present invention provides a kind of pulverizer that can pulverize effect better, and specific technical scheme is as follows: [0004] An ultrafine material pulverizer, comprising a left nozzle and a right nozzle, and an impact chamber between the left nozzle and th...
