The Cleveland Vibrator Company Model EMS Electro-Mechanical Screener Feeders with twin motor drives are designed for precise screening where high efficiency is required in the end particle size. Units are mounted horizontally, requiring no gravitational assistance for product conveying along the screening surface. EMS Screeners are typically equipped with 1800 RPM vibrators that provide 0.10” stroke. Force output of the drives may be varied to decrease stroke, thereby reducing final conveying speed.
For difficult-to-handle, light density, fluffy products, or where large screen openings (i.e. one inch square or larger) are being used, lower frequency, higher amplitude drives may be substituted. For these types of applications, 900 and 1200 RPM drives are available as an option. Drives can be mounted above or below the screening surface.

Note: our screeners can be built to your specifications.

+ Air-spring base mounting or overhead coil spring suspension mounting
+ Dust-tight covers and sight ports
+ Booted inlets and outlets for dust containment
+ Tension wedges for quick changing of screen decks
+ Twin motor starter for manual on-off operation
+ Variable frequency controls to vary the feed rate
+ Ball tray decks to reduce screen “plug” blinding
Principle of Operation
Twin motor vibrator drives arranged for counter rotation provide a linear vibratory action which conveys the product across the screening surface. Standard motors are 1800 RPM. 1200 RPM and 900 RPM drives will be provided as required. All motors are TENV design.
Adjusting the Eccentric Weights
Force is easily adjustable from 0 to 100 percent. Percentage settings are marked on the shaft of each motor. Loosening one bolt on the outer eccentric weight enables the eccentric weight to be adjusted to the desired percentage of maximum force available. It is imperative that motors be wired for counter rotation.
