Scalps in-line with pneumatic conveying systems gently, at high rates
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" (1219mm) and 60" (1525mm) 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.
