The features such as strong, it is widely used in the processing industry such as hard alloy and optical glass.In recent years, with the hair of world semiconductor industry
Exhibition, carborundum are used widely in monocrystalline silicon, polysilicon, the multi-wire saw of piezoelectric quartz crystal and grinding, especially existed
It is even more so in the photovoltaic industry of high speed development.Its quality is not only relevant with its purity, and relevant with its grain fineness, and its is pure
Degree is higher, its thinner application quality of particle is higher, and application is wider.And traditional production method can only produce 10 μm or so
Product, and particle diameter distribution is too big, and particle is uneven, and impurity is more.
Utility model content
In view of the shortcomings of the prior art and problem, the utility model provide a kind of silicon carbide micro-powder mechanical classification and crushed
Device, crushed again after sizing screening grain diameter after graded crushing, simple in construction, operating efficiency good with crushing effect
The features such as high.
To reach above-mentioned purpose, the technical solution adopted in the utility model is：A kind of silicon carbide micro-powder mechanical classification crushes
Device, including body, along the body be sequentially provided with from left to right interconnected material charging region, freeze space, the first fracture area,
Second fracture area and the 3rd fracture area；The material charging region is arranged on the oblique upper of the freeze space.
Further improved as the utility model, the first fracture area periphery is provided with primary screen cloth；Described first
The discharge outlet of fracture area is provided with primary material collection box；The second fracture area periphery is provided with intermediate screen cloth；It is broken described second
The discharge outlet in broken area is provided with middle rank material collection box；Discharge outlet in the 3rd fracture area is provided with the 3rd material collection box.
It is further improved as the utility model, the freeze space of the body, the first fracture area, the second fracture area and
Feeding spiro rod is additionally provided with 3rd fracture area.
Due to the utilization of above-mentioned technical proposal, the utility model has following advantages compared with prior art：
The silicon carbide micro-powder mechanical classification breaker of the utility model, carborundum put into by material charging region cold
Freeze area, first pass through freeze space and carry out fast cooling, reduce the toughness of carborundum, broken ground effect is more preferable, so as to improve work
Efficiency；After distinguishing sizing screening grain diameter after the progress graded crushing of the first fracture area, the second fracture area and the 3rd fracture area
Crushed again, realize and crush and sort step by step step by step, obtain the silicon carbide micro-powder of specific model, the utilization rate of raw material is higher,
Useless powder is few, and the crystal formation of the silicon carbide micro-powder of acquisition is preferable；The flour extraction in carborundum block process of lapping can be effectively improved,
Effectively reduce the waste of raw material.

Freeze area 3 and carry out fast cooling, reduce the toughness of carborundum, broken ground effect is more preferable, so as to improve operating efficiency.
The periphery of first fracture area 4 is provided with primary screen cloth 7；Discharge outlet in the first fracture area 4 is provided with primary material collection box
8；The periphery of second fracture area 5 is provided with intermediate screen cloth 9；Discharge outlet in the second fracture area 5 is provided with middle rank material collection box 10；
The discharge outlet of three fracture areas 6 is provided with the 3rd material collection box 11.
Distinguish sizing screening particle after graded crushing is carried out in the first fracture area 4, the second fracture area 5 and the 3rd fracture area 6
Crushed again after particle diameter, realize and crush and sort step by step step by step, obtain the silicon carbide micro-powder of specific model, the utilization rate of raw material
Higher, giving up, powder is few, and the crystal formation of the silicon carbide micro-powder of acquisition is preferable；It can effectively improve in carborundum block process of lapping
Flour extraction, effectively reduce the waste of raw material.
