LL Coal Dewatering Vertical Scrape Centrifuge
Product Description
A)Wet materials are feed into the mouth of centrifuges, then are accelerated by the rotated distribution cone and move rapidly towards the space between screen and rotor. With the centrifugal force, the smaller particles of material get closed to the screen surface, liquid and part of the particle size of less than 0.5mm of material get across the material space and screen gap, then are thrown out the screen, the larger particles of material soon slipped into spiral nesting mouth along the screw blade with the action of gravity and centrifugal force. fine material attached to the screen surface are discharged by the scraper centrifuge through blade action, while the liquid through the screen and fine material are thrown into the water tank then outflow through the drain, so as to achieve a solid-liquid separation.
