The through-hole of the bottom connection of mounting groove；The position of opening portion on the cylinder close to the mounting groove offers insert port, institute
It states nozzle body and gos deep into inner barrel across the insert port；It is provided between the mounting groove and the cylindrical support seat close
Sealing；The driving device for driving the cylindrical support seat is provided on the cylinder.
Further, the size of the insert port on the cylinder is less than the size of cylindrical support seat, the cylindrical branch
Support seat is resisted against on the side wall of the insert port.
Further, the bottom of the mounting groove is provided with limited step, is provided at the limited step and cylinder
The sealing element of support base fitting.
Further, be coaxially fixed with shaft on the cylindrical support seat, offered on the side wall of the mounting groove with
The corresponding mounting hole of shaft, the shaft stretches out the mounting groove and is provided with rotating seal between mounting hole, described
Driving device is arranged in the outside of mounting groove and connect with the shaft.
Due to the adoption of the above technical solution, the utility model has the advantage that cylindrical support seat is able to drive spray
Mouth ontology is with respect to barrel body rotation, and the space of strafing of Laval nozzle occurs to change up and down therewith, when Laval nozzle is strafed downwards
When, material a part of cylinder body bottom directly obtains abundant crushing, and another part is boosted by air-flow, enters high pressure gas from top to bottom
The joint of stream is sufficiently crushed, and so as to reduce the residual material after shutting down, improves crush efficiency and yield.

Specific embodiment
The above objects, features, and advantages of the utility model in order to facilitate understanding, are illustrated below with reference to embodiment.It answers
Understand, these embodiments are merely to illustrate the utility model rather than limitation the scope of the utility model.For these implementations
A variety of modifications of example will be apparent to those skilled in the art, the general principles defined herein,
It can be achieved in other embodiments without departing from the spirit or scope of the present utility model.
A kind of airslide disintegrating mill shown in Figure 1, comprising: along the cylinder 1 that vertical axial direction extends, the cylinder
The lower part of body 1 is crushed zone 11, and top is separated region 12；Tracheae 2 at the crushed zone 11 and a plurality of is set
Laval nozzle 3, the tracheae 2 arrange that the Laval nozzle 3 is connected to the tracheae 2 and cylinder 1 around cylinder 1；Setting exists
Grading wheel 4 and discharge port 5 at the separated region 12.Feed inlet 6 is additionally provided on cylinder 1, feed inlet 6 is usually located at separation
