Below advantage of the present utility model or principle are described:
1, in the grinding machine running, motor drives the rotation of high speed mill by rotating shaft, after material is fallen mill, collision for the first time can take place with the deflector chute on the mill that rotates at a high speed, under the effect that mill rotates at a high speed, material after taking place to collide is for the first time thrown away at a high speed again, collision for the second time takes place with guide ring, rebound to mill behind the material high velocity impact guide ring, because mill is inclined, material has the trend of rolling to the middle part, has only when the material particles after the pulverizing reaches to a certain degree for a short time, material falls from the gap between mill edge and the guide ring under the self gravitation effect; Realize material grinding by mode, improved efficient, reduced energy consumption with the continuous high speed bump;
2, the guide recess has increased the collision probability of material, also is convenient to material and throws away at a high speed under the effect of deflector chute;
3, the guide ring internal face is curved, can with the material head-on crash that throws away at a high speed, and material rebounded to mill, improved the probability of material collision, and convenient short grained material skids off from the bottom;
4, after material enters from charging aperture, fall on the material separating disc earlier and push away long-pendingly, fall through the first blanking platform, the second blanking platform successively, make that material is more uniform to be fallen on the mill;
5, the small particles material after mill is pulverized enters cavity of resorption, and is ground by moving nog plate and quiet nog plate, material is further pulverized, because roll flute and the distance between the roll flute on the quiet nog plate on the moving nog plate are 1.5 centimetres to 3.5 centimetres; Lapping mode herein is also different with traditional lapping mode, and when tradition was ground, rotating speed was lower, the roll flute distance is more approaching, and when grinding, the rotating speed height, the roll flute distance on quiet nog plate and the moving nog plate is far away; herein can not produce any contact, when small particles material runs up, form logistics field flow at high speed at this place, grinding runs foul of each other, the energy consumption of this mode is low, and grinding effect is good;
6, there is slanted angle between roll flute on the moving nog plate and the roll flute on the corresponding quiet nog plate, can prolongs the time of staying of material.
