Rotary Screen Sieve For Dewatering And Grading

Currently available in 30-, 40-, 48- and 60-inch diameters, the separator is designed to increase safety, provide stronger construction and allow for a more sanitary process. The totally enclosed weight guard on the separator prevents “reach-in” injuries, complying with European CE Standards. The extremely rugged construction of this machine utilizes conical construction rather than flat plates which creates a more rigid geometric structure. Additionally, the open base construction allows for cleaning underneath the unit, therefore preventing dirt and product build-up.

What it does…

Separate solids from liquids or segregate dry materials into various sizes. Particles as fine as 400 mesh (37 microns) can be screened, with up to 4 screen decks incorporated in one separator. No special flooring or foundation is needed and less working floor space is required. Simple and efficient design requires less horsepower. Other features include long screen life and ease with which screens may be changed.

How it works…

Basically, the Separator is a vibratory screening device that vibrates about its center of mass. Vibration is accomplished by eccentric weights on the upper and lower ends of the motion generator shaft. Rotation of the top weight creates vibration in the horizontal plane, which causes the material to move across the screen cloth to the periphery. The lower weight acts to tilt the machine, causing vibration in the vertical and tangential planes. The angle of lead given the lower weight with relation to the upper weight provides variable control of the spiral screening pattern. Speed and spiral pattern of material travel over the screen cloth can be set by the operator for maximum throughput and screening efficiency of any screenable product … wet or dry … heavy or light … coarse or fine … hot or cold.
