Linear vibrating sieve is a kind of closed and light weight vibrating sieve equipment,it uses a vibration motor as the vibration source, which make the material jump in straight line on the screen surface,material evenly go into the feed port of linear vibrating screen from the feeding machine,generating multiple materials through the multi-layer rectangular screening mesh,and be discharged from each outlet.Main functions of linear vibrating screen are grading,filtering and removing impurity.Linear vibrating screen has a unique effect on powdery, granular materials selection and classification.
