It is high speed separator. It has better separation. The separator is consisted of main body, driving device, bowl collecting pan and liquid-in bearing seats. The upper of the bowl is flexible maishaft and the lower of it is damp floating. The mainshaft is connected with a driven wheel by the coupling seat with the buffer. The power is transmitted to the driven wheel by the motor through the transmisson belt and the tensioner to make the bowl rotate around its pwn axis at an overspeed and form a strong centrigugal force field.
