Supersonic velocity pipe is provided in fast nozzle, superonic flow nozzzle outboard end connection gas-guide tube, superonic flow nozzzle side is provided with
Inclined feed inlet, feed inlet are connected with superonic flow nozzzle, and crusher cavity bottom corresponds to impingement plate bottom and is provided with discharge port.
As further program of the utility model：The supersonic velocity pipe is arranged to trumpet type.
As the utility model further scheme：The impingement plate is cylindrical structure and axial line is perpendicular to level
Face is overlapped with supersonic velocity tube axis line.
As the utility model further scheme：The impingement plate top sets tapered.
Compared with prior art, the beneficial effects of the utility model are：
The playpipe and impingement plate of the superonic flow nozzzle of the utility model ingehious design, are realized to the multiple of high rigidity material
Efficient pulverizing is gas-solid mixing multiple impacts first, then hits the crash panel of special designing, powerful smashing together；It is efficient,
The powder granularity narrow range of crushing, critical component long lifespan solve conventional fluidization bed airslide disintegrating mill, are only mixed using gas material
It closes, expects dnockout, efficiency is low, the disadvantage of low output；In addition the utility model avoids horizontal crushing, and gas-solid mixing body is moving
It is affected by gravity in the process, generates the offset of collision, cause abrasion asymmetric, fail fast disadvantage, while the powder grain crushed
It is narrower to spend scope；The utility model has a wide range of application, suitable for industrial ceramics powder, electronic ceramics powder, various silicon powders
Such as crushing of silicon monoxide powder and silicon dioxide powder high rigidity powder.
Description of the drawings
Fig. 1 is the structure diagram of the board-like supersonic jet mill of normal impact.
Specific embodiment
The following is a combination of the drawings in the embodiments of the present utility model, and the technical scheme in the embodiment of the utility model is carried out
It clearly and completely describes, it is clear that the described embodiments are only a part of the embodiments of the utility model rather than whole
Embodiment.Based on the embodiment in the utility model, those of ordinary skill in the art are without making creative work
All other embodiments obtained shall fall within the protection scope of the present invention.
Referring to Fig. 1, in the utility model embodiment, a kind of board-like supersonic jet mill of normal impact, including powder
Broken machine cavity body 4, crusher cavity 4 is vertically arranged, and impingement plate 1,4 upper end of crusher cavity are provided in crusher cavity 4
Corresponding 1 top of impingement plate is provided with superonic flow nozzzle 3, and supersonic velocity pipe, superonic flow nozzzle 3 are provided in superonic flow nozzzle 3
Outboard end connects gas-guide tube, and 3 side of superonic flow nozzzle is provided with inclined feed inlet 2, and feed inlet 2 connects with superonic flow nozzzle 3
Logical, 4 bottom of crusher cavity corresponds to 1 bottom of impingement plate and is provided with discharge port.
The supersonic velocity pipe is arranged to trumpet type.
The impingement plate 1 is cylindrical structure and axial line is perpendicular to horizontal plane, is overlapped with supersonic velocity tube axis line.
1 top of impingement plate sets tapered.
The superonic flow nozzzle 3 generates high speed and high pressure air-flow, and continuous sucking accelerates so that powder is in superonic flow nozzzle
Because disorderly air-flow makes to collide with each other between powder particle, while so as to reach crushing, then solid and gas mixed flow directive is set
It is hit on the impingement plate in front of nozzle, so as to reach powerful smashing again, whole process is complete in crusher cavity 4
Into.
The operation principle of the utility model is：The playpipe of the superonic flow nozzzle of the utility model ingehious design and collision
Plate realizes the multiple efficient pulverizing to high rigidity material, is gas-solid mixing multiple impacts first, then hits special designing together
