Description

Energy-saving ultrafine grinder

Technical Field

The utility model relates to an energy-saving superfine pulverizer belongs to crushing apparatus technical field.

Background

At present, most of the crushers for crushing Chinese herbal medicines rely on a vertical micro-crusher, which comprises a crushing chamber, a cutter head, a square cutter block, a grading wheel, a gear ring, a driving main transmission, a grading transmission and the like. The side surface of the crushing chamber is provided with a feeding mechanism, the discharged material is collected by a top induced draft fan and a cyclone separator, and the pulse bag type dust collector removes dust. The material is fed into the crushing chamber by the feeding mechanism and is sheared by the collision among the cutter head, the cutter block and the fixed gear ring which rotate at high speed, the particles are quickly split into micro powder, the material enters the grading wheel for grading through the guide ring under the action of negative pressure, the graded particles pass through gaps among blades of the grading wheel, and the particles are subjected to three forces simultaneously, so that the centrifugal force generated by the high-speed rotation of the grading wheel, the gravity of the particles and the centripetal force generated by negative pressure airflow are generated. Only the micro powder particles with the negative pressure centripetal force larger than the centrifugal force and the self gravity can smoothly pass through the grading wheel to enter the cyclone separation and collection, the large powder particles are thrown to the guide ring to enter the crushing chamber to be crushed again under the action of the centrifugal force and the gravity, the size of the particle diameter of the material is changed along with the change of the rotating speed of the grading wheel, and the higher the rotating speed, the smaller the graded powder particles. However, the existing micro-pulverizer has the following disadvantages:

1. the negative pressure in the crushing chamber of the micro crusher is realized by the induced draft fan, so the required power of the induced draft fan is higher, and the power consumption is high;

2. when some viscous materials are crushed, the discharging effect is not ideal, the crushed superfine materials are repeatedly crushed in the crushing chamber, the yield is low, and the production speed is slow;

3. the heat that produces at high-speed crushing in-process dispels the heat slower, and the machine intracavity portion temperature is high, is not suitable for the crushing of heat sensitive material, and crushing in-process because the machine intracavity temperature is too high, arouses the material to discolour easily, influences final material crushing quality.
