SZF linear vibrating screen is widely used in the classification of peanuts. It is easy to use and handle. It saves time and labor and saves labor cost. The SZF series linear vibrating screen uses the electric vibration exciter as the vibration source, so that the material is thrown up on the screen. At the same time, the material is moved forward straight line, and the sieve net is properly matched to reach the screening purpose. The material from the feeder is evenly entered into the feeding port of the sieving machine. Several kinds of products and unqualified sieves are produced by the multi-layer screen. They can be discharged from their respective outlets and can be used for automatic operation in the assembly line. The utility model has the advantages of low energy consumption, high efficiency, simple structure, easy maintenance, and completely closed structure without dust overflow.
