Micro crusher with inner and outer barrels

Abstract

The invention discloses a micro crusher with inner and outer barrels, comprising a base support frame, an outer barrel, an inner barrel, a left safety hood and a right safety hood, wherein the outer barrel comprises an upper cover and a lower base, the interior of the outer barrel is cylindrical and is divided into a plurality of impact spaces by means of a plurality of radial impact toothed plates, the inner barrel is concentrically installed inside the outer barrel, a circle of at least two crushing cutters are installed on the wall of the inner barrel corresponding to each impact space andare connected with a small motor respectively, and the inner wall of the outer barrel of each impact space is provided with an axial impact toothed plate. In the micro crusher with the inner and outer barrels disclosed by the invention, the inner barrel rapidly rotates inside the outer barrel, the crushing cutters rotate at high speed under the drive of the corresponding small motors, and small particles obtained after primary crushing are stirred and cut at high speed by the crushing cutters inside each impact space, impact with radial and axial impact toothed plates at high speed and gradually diminish after a plurality of times of impacting; and the two actions of stirring and impact cutting are separated, and a large impact space is divided into a plurality of small independent spaces, so that the impact probability of the crushed particles is improved, and the refining and pulverizing speed of the crushed particles is increased, thereby achieving the effects on improving the processing efficiency and reducing the energy consumption.

Description

technical field [0001] The invention relates to a pulverizing machine, in particular to a micro pulverizer with inner and outer tubes for pulverizing and pulverizing relatively large plastic particles. Background technique [0002] The existing fine pulverizer only has an outer cylinder, the blade or hammer head is installed on the central shaft, and the central shaft rotates under the drive of the external pulley, and the blade or hammer head hits the particles at high speed to form fine particles, but there are still Most of the particles are still relatively large and cannot be output in time for further processing. They are repeatedly hit by knives or hammers in the barrel, and the refinement is relatively slow, so the processing efficiency is low and the energy consumption is relatively high. Contents of the invention [0003] In order to improve the refining speed and efficiency of the pulverizer, the invention provides a micro pulverizer with an inner and outer ...

[0002] The existing fine pulverizer only has an outer cylinder, the blade or hammer head is installed on the central shaft, and the central shaft rotates under the drive of the external pulley, and the blade or hammer head hits the particles at high speed to form fine particles, but there are still some fine particles in the fine particles. Most of the particles are still relatively large and cannot be output in time for further processing. They are repeatedly hit by knives or hammers in the barrel, and the refinement is relatively slow, so the processing efficiency is low and the energy consumption is relatively high.
