SFJZ vibration screen SFJZ vibration classification screen is mainly used for screening and grading of feed mill powder and pellet feed, can also be used for the classification of raw materials feed factory at the beginning of Qing and two times after crushing of intermediate products. In addition, the utility model can be widely used in a variety of food, food, chemical industry, sugar refining, mining, paper and other industries of raw materials and finished goods selection and classification. Performance characteristics: The probability of screening principle, through the reasonable choice of screen aperture and screen angle, makes the sieve particles rapidly sieving; The larger screen and right angle combination separation size smaller; And compared with ordinary sifter mesh, hole plugging tendency is greatly reduced, the screening process can be strengthened; - screen length is much shorter than the ordinary sifter and does not affect the classification effect.
