Electro-mechanical ball tray deck screener

This Electro-mechanical Ball Tray Deck Screener (EMBS) is engineered to provide high-efficiency for recycling applications where precise end particle size is paramount. The EMBS achieves a high degree of practicality from its ball tray deck, (the physical area beneath the surface of its wire cloth screen that contains balls in specialized compartments.)

The linear vibratory design of the EMBS actuates vigorous ball bouncing movements within their ball deck compartments and against the underside of the screen section. As the balls randomly strike the bottom of the screen, they knock out angular pieces that have wedged into screen openings. This action ultimately keeps openings clear for more efficient screening, thereby eliminating the potential plug blinding that can occur when material gets caught in screen openings as well as associated production shut downs for manual cleaning.

EMBS units are mounted horizontally, requiring no gravitational assistance for product conveying along the screening surface. The EMBS screener is equipped with 1800 RPM vibrators that provide 0.10 inch stroke. Force output of the drives may be varied to decrease stroke to reduce final conveying speed. For difficult to handle or light density products, or where screen openings greater than one inch are being used, a lower frequency, higher amplitude drive may be substituted with the 900 or 1200 RPM drive options.
