Q: Does the Fluid Energy processing plant provide screening and classifying services?

A: Absolutely.  Fluid Energy provides both stand-alone and supplemental screening/classifying services. We offer two styles of screening, turbo and shaker, as well as air classification.  Our processing plant in Hatfield, PA has several shaker screeners to supplement our milling and drying capabilities, including Food Grade capacity that meets FSSC 22000.  When possible, the screening unit is installed in line with milling, blending or drying equipment to provide a continuous process that minimizes handling and saves money.  If other services are not required, a station can be arranged to accommodate either a screener or air classifier to separate materials into different particle sizes as a stand-alone process.

A shaker screen separates materials by size using vibration, where material is fed onto a vibrating, flat screen.  The vibration causes finer particles to fall through the mesh, while larger particles bounce across the surface toward the outlet located on the outside of the deck. Multiple decks can be used when making multiple splits and sonication can be used to enhance separation of difficult and/or super fine powders.  The product collectors in our processing stations have been designed to accept a multi-deck screen without interfering with process.  This allows the screening process to be added without increasing the workload for the operator.

Fluid Energy employs a turbo-style screener that uses a slightly more energetic method to separate powders than the shaker style.  With a turbo screener, feed material is pneumatically conveyed horizontally into the screen via a vacuum being drawn from the back side of the screen.  Finer materials are pulled through the screen and conveyed to a collector.  The oversize material bounces off the screen and drops into a collection drum below.  A rotating wand on the back side of the screen provides a cleansing air sweep to keep the screen free of build-up.  Due to the feed arrangement, the turbo screen is most often used in a standalone arrangement.  It works best with materials that would clog a shaker screener or have a very low percentage of oversized particles. 

The Fluid Energy RotoSizer classifier works by using controlled airflow and wheel speed to separate powders into two distinct particle sizes based on their mass and how they interact with the air stream. The powder is fed into the classifier, where air currents carry the material up to a spinning classifier wheel.  Finer, lighter particles slip through the wheel while larger, heavier particles are rejected and discharged through the bottom of the unit.  This method is effective for separating powders that are difficult to screen, due to build up on the screens.  The RotoSizer is very effective at separating super fine particles and most often used when the split required is finer than 45 microns.
