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.
Material stratification by wave movement and rolling of material

Projects (transportation from twin-roll drum screen to cross roller screen):
1. Working condition:
Coal quality: raw coal + coal slime, ration of raw coal and coal slime 1:1.5-2;coal≤8mm accounts for 65%
Water content: 10%-20% Requirement of particle size: 8mm
2. Equipments before and after transformation:
Before: 2 sets of twin-roll screen (ZZS-800), design handling capacity: 800t/h, rated power: 230Kw
After: 2 sets of cross screen (CRS-2220), design handling capacity: 800t/h, rated power: 120Kw
