SZF series linear vibrating screen uses motor vibrating as excitation source to throw the materials on the screen, while forward tor linear motion, the material from the feeder uniform enters feed mouth of screen, through multi-storey screen to produce different sizes of products on the sieve or under the sieve, and then discharge from their exports. It has the features of low energy consumption, high efficiency, low noise, simple structure, easy maintenance, fully closed structure without dust scattering characteristics.
