Dual Screen Ultra High Capacity Screener

This Pneumati Sifter in-line vibratory separator from Kason employs twin screening decks with internal bypass to sift/scalp up to 60,000 lbs/hr (27,200 kg/hr) of free-flowing material in-line with dilute-phase pneumatic conveying systems. The chambers above the top screen and below the bottom screen are connected by a central bypass chute, causing on-size material entering the central chamber to reach the bottom outlet via two pathways: upward through the top screen, then downward through the chute; or downward through the bottom screen. Oversize material is ejected through a spout at the periphery of the lower screen.

A tangential inlet along the horizontal centerline of the central chamber prevents material from impacting screens at 90¡ angles. Gradual changes in flow stream direction minimize breakage of oversize foreign material and subsequent material contamination, and reduce screen breakage significantly.

The unit is equipped with "ball tray" anti-blinding devices and is intended to remove oversize particles from plastic resin, flour, starch, sugar, and numerous food and chemical products gently, at ultra-high rates. Applications include loading and unloading of trucks and railcars, and conveying of material between process or storage areas.

Offered in 48" (1219 mm) and 60" (1525 mm) diameters, the twin-screen machines are available to 3-A, FDA, BISSC and other sanitary standards, and can be disassembled rapidly for thorough wash down. A range of accessories is available including clean-in-place spray heads and quick-release clamshell lids for rapid screen changes.
