Gyratory motion rapidly distributes, stratifies, and separates

The unique gyratory-reciprocating motion begins with a horizontal circular motion at the feed end that immediately spreads the material across the full width of the screen.

1. Circular motion at feed end

The circular motion gradually diminishes along the length of the machine to an elliptical path, and finally to an approximate straight-line motion at the discharge end.

2. Changing to elliptical motion at center

This motion allows the machine to process material at a higher capacity and improves screening performance for near-size material.

3. Straight-line motion at discharge end

There is no vertical component to this motion – thus keeping the material in constant contact with the screen surface.

Floor Mounting

The low transmitted forces of the ROTEX counterbalanced drive allow the unit to be floor mounted in properly designed structures where some other types of equipment cannot. Mounting may be directly on the floor or on an elevated structural steel framework, the elevated position permitting drums or other equipment to be located under the machine. ROTEX application engineers can recommend a stand for any specific application.

Cable Suspension

APEX Screeners can be cable-suspended from the four corners of the machine, thereby isolating out-of-balance screening forces from the surrounding structure. Accurate counterbalancing of the APEX Screener makes this installation option possible. If the existing overhead structure is not suitable for cable suspension, or is structurally unable to support the cable-suspended unit, the APEX Screener can be suspended from a floor-mounted cable support stand. As with conventional cable suspension, this option effectively isolates the horizontal out-of-balance screening forces, helping to minimize costs for new structures as well as permitting the use of older structures which might not otherwise support cable-suspended equipment.
