YLK Lab Automatic Vibrating Screen is suitable for particles distribution analysis of chemical powder or laboratory solid liquid material. It has features of low noise, high efficiency and precision.This device is made up of milling roller, screen system, feed system and the receiving system. After grinding material, it will smash & sieve the process of media balls and powder. And then reaches granularity,the material would sieve out through the sieve system. Collecting the materials of sieving out by the receiving system. Material continuous feeding through the feed system.
