2. Particle size: 3-13mm
3. High environmental protection
4. No manual cleaning at all
5. Intelligent PLC control function
6. High tolerance of impurities
7. Small space occupation

Working principle

The screen deck of cross roll screen is composed of multiple sets of rotary rollers with disks, all disks on adjacent roller are crossed to form moving screen holes, the materials in the screening area are classified during moving process, small particles go downward and large particles move forward, thus small particles are exposed to rotating disks and are forced to go through the holes via rubbing of adjacent disks. The large particles impact and break the agglomerated particles during movement and clean the small particles on the rollers and disks. Below the rollers, there are scrapers to clean the residues and ensure open holes without plugging, sticking and pegging.
