Abstract
The utility model discloses an air flow crushing-grading mill. A grading cylinder of a material inlet pipe is arranged at the side part of the air flow crushing-grading mill, the grading cylinder is provided with an air flow nozzle connected with an air source, and a grading impeller driven by a power device, the grading impeller is arranged horizontally, and a material outlet pipe corresponding to the position of the grading impeller is arranged at the side part of the grading cylinder; a grading area and a crushing area are arranged in an inner cavity of the grading cylinder from top to bottom, the material inlet pipe and the air flow nozzle are both positioned in the crushing area, and the grading impeller is positioned in the grading area; and the grading impeller comprises a wheel disc connected with the power device, and impeller blades which are annularly distributed on the wheel disc and are arranged at intervals. The air flow crushing-grading mill has the advantages that separated materials are uniform in granularity and high in grading precision.
Description
Technical field
The utility model relates to a kind of jet mill grinding mill.
Background technology
In the material disintegrating apparatus, the impact grinding meeting produces very big pollution to material, and is not suitable for the higher material of hardness.Existing a kind of vertical jet mill grinding mill has solved the problems referred to above, it comprises that sidepiece is provided with the assorting cylinder that feed pipe, top are provided with discharge nozzle, the nozzle that is connected with source of the gas is housed on the assorting cylinder, nozzle is positioned at the below of feed pipe, also be equipped with by electric motor driven classifying turbine on the assorting cylinder, classifying turbine vertically is provided with, after material enters assorting cylinder, nozzle ejection air-flow makes material collide pulverizing mutually, and the classifying turbine rotation makes the material after the pulverizing discharge by the top discharge pipe.Because classifying turbine vertically is provided with, be to produce vortex by air-flow the material after the powder essence is risen again by classifying turbine rotation carrying out classification, had the uneven phenomenon of granularity by the material after the sorting, promptly there is the not high shortcoming of effectiveness of classification in this jet mill grinding mill.
The utility model content
The technical problems to be solved in the utility model provides the high jet mill grinding mill of a kind of sorting material uniform particles, effectiveness of classification.
For solving the problems of the technologies described above, the jet mill grinding mill that is provided comprises that sidepiece is provided with the assorting cylinder of feed pipe, air current spray nozzle that is connected with source of the gas and the classifying turbine that is driven by power set are housed on the assorting cylinder, its design feature is: described classifying turbine is horizontally disposed with, and the sidepiece of assorting cylinder also is equipped with and the discharge nozzle corresponding with the classifying turbine position.
The assorting cylinder inner chamber is divided into graded region from top to bottom and pulverizes the district, and described feed pipe and air current spray nozzle all are positioned at pulverizes the district, and classifying turbine is positioned at graded region.
Power set are the motor that is packed on the assorting cylinder outer wall.
Classifying turbine comprises the wheel disc that is connected with power set and is periphery on wheel disc and the impeller blade that is provided with at interval.
After adopting said structure, after material entered assorting cylinder, nozzle ejection air-flow made material collide pulverizing mutually, and power set drive the classifying turbine rotation, and the material after the pulverizing is discharged by the top discharge pipe.Because classifying turbine is horizontally disposed with, after air-flow produced vortex, the material after the powder essence rose and carries out classification by the classifying turbine rotation again, and the material of larger particles can not selected by classifying turbine, thereby there is uniform granularity in the material after the sorting.In sum, the utlity model has the high advantage of effectiveness of classification.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 among Fig. 1 along A-A to the schematic diagram of analysing and observe.
The specific embodiment
Jet mill grinding mill as shown in Figure 1, it comprises that sidepiece is provided with the assorting cylinder 2 of feed pipe 3, assorting cylinder 2 inner chambers are divided into graded region from top to bottom and pulverize the district, the bottom of assorting cylinder 2 is supported by frame 1, air current spray nozzle 4 that is connected with source of the gas and the classifying turbine 5 that is driven by power set are housed on the assorting cylinder 2, and the sidepiece of assorting cylinder 2 also is equipped with and the discharge nozzle 6 corresponding with classifying turbine 5 positions.Feed pipe 3 and air current spray nozzle 4 all are positioned at pulverizes the district, and classifying turbine 5 is positioned at graded region.Above-mentioned power set are the motor 7 that is packed on assorting cylinder 2 outer walls.Air current spray nozzle 4 is established four altogether and is periphery on assorting cylinder 2, and air current spray nozzle 4 is positioned at the below of feed pipe 3, and the structure of air current spray nozzle 4 is a prior art, does not repeat them here.In conjunction with illustrated in figures 1 and 2, above-mentioned classifying turbine 5 is horizontally disposed with, it comprises the wheel disc 51 that is connected with motor 7 and is periphery on wheel disc 51 and the impeller blade 52 that is provided with at interval, the outer wall of above-mentioned discharge nozzle 6 and impeller blade 52 corresponding settings, be that material after the sorting can enter discharge nozzle 6 from the centre of a plurality of impeller blades 52, the structure that above-mentioned impeller blade 52 is installed on the wheel disc 51 is similar to shutter.
The utility model is applicable to the dry pulverization process of the various materials of Mohs' hardness below 9, be particularly suitable for high rigidity, high-purity and high added value material grinding, the rotating speed of sheet number, size and motor that can be by adjusting impeller blade is adjusted sorting particle size, adjustable between the product granularity D97:2-150 micron, particle shape is good, narrow particle size distribution.Low temperature does not have medium to be pulverized, and especially is fit to thermal sensitivity, and low melting point contains the pulverizing of sugar and volatile material.
