Description
Technical field
The present invention relates to silicon carbide production equipment technology, in particular to a kind of little particle silicon carbide production equipment.
Background technique
The system that the production of Conventional silicon carbide granularity sand is all made of washing, working principle are sunk in water according to each granularity section
The difference of reduction of speed degree carries out segmentation production, its advantage is that segmentation accuracy is high, it can be more by national standard, Nippon Standard, European standard etc.
A standard paragraphs are produced, the disadvantage is that water consumption big (30 tons of silicon carbide water consumption per ton or so), a low efficiency (batch silicon carbide
Want 48 hours from output is put into), number of dropouts big (loss up to 3%), big (silicon carbide per ton dries power consumption for drying power consumption again
1285kwh) etc..And the silicon-carbide particle granule size of the production line production of existing dry type silicon carbide is uneven, is carefully analyzed,
We have found that the main reason is that caused by host top grading wheel is improper, in some cases too with the spacing of cylinder lateral wall
Greatly, bulky grain " can slip away " in some moment along grading wheel side wall.Such as it is had in the product of 200 mesh of production a small amount of
The big grain of 0.1mm or more, this does not allow, because the silicon carbide granular sand of 200 mesh is mainly used for cutting precise part,
If there is big grain exists, whole part cutting can be scrapped, if carefully and there is no cutting efficiency very much, so, it can only be in certain model
Finished product in enclosing can be just suitable.Therefore, it is uniform to design a kind of particle, standard compliant silicon carbide granular sand process units is
It is necessary to.
