Vertical Spout Magnet
Engineered to remove fine to large ferrous contaminants from high-volume, gravity-fed product streams, these vertical spout magnets are suited for products that would bridge or choke in a magnetic tube type separator. Ferrous contaminants are easily removed from products that are moist, lumpy, granular, or in powder form. Two powerful opposing magnets mounted to the outside of the housing draw tramp metal out of the product stream. A center diverter on the housing inlet helps direct product towards the magnets. A single trap face design eliminates the possibility of the captured tramp metal being washed off back into the product stream. The magnets retract from the housing taking the tramp metal out of the product flow area. Puritan Magnetics Inc., Oxford, MI 248-628-3808 www.puritanmagnetics.com

Vibratory Check-Screener Enhancement
The Vibrastop is the latest in starter technology to provide rapid startup and shutdown, eliminating excessive sieve movement. Vibration is transmitted into industrial screening machines by means of a vibratory electric motor. As with most motors, there is a short period of time before the operating speed is reached from initial startup and an even longer time period during shutdown until the motor finally comes to rest. These two phases cause the motor to pass through its resonant frequency and as a result, up to six times more vibration can be transmitted into the sieve when compared to what is normally transmitted during normal sieve operation. This resonance causes excessive noise but more problematic movement in the sieve. Russell Finex Inc., Pineville, NC 800-849-9808 www.russellfinex.com

Standard line of screens with holes in a 60- or 90-degree pattern are available with maximum guaranteed perforated area of 18x21 in. Tech-Etch Inc., Plymouth, MA 508-747-0300 www.tech-etch.com

Magnetic Pneumatic Line Housing
The custom cart-mounted magnetic pneumatic line housing’s portable design allows it to be utilized in multiple locations such as loading/unloading from railcar, truck, or silo storage systems for dry/bulk pneumatic transfer applications. The unit’s staggered magnetic tube configuration ensures that all product flowing through the housing makes repeated contact with the magnets. The resulting capture rate of ferrous and weakly magnetic stainless contaminants far exceeds any other magnetic separator available for this type of application. A removable screen has also been incorporated to capture non-magnetic objects, making this unit an exceptional piece of equipment for all-around product purification and equipment protection.

Sanitary Centrifugal Screener
The Centri-Sifter centrifugal screener features a three-bearing shaft that cantilevers for quick removal of internal components. External roller bearings located at the motor end of the shaft and on a hinged cover at the discharge end provide maximum support and vibration-free operation under heavy loads. When the hinged end cover is open, the shaft cantilevers on a third externally-mounted roller bearing located between the motor-end bearing and material feed point, allowing internal components to slide freely from the opposite shaft end. Equipped with Clean-In-Place (CIP) spray balls for rapid sanitizing using steam or cleaning solution, the unit is constructed of stainless steel finished to industrial, 3-A, FDA, BISSC, and other sanitary standards, and is equipped with a stainless steel motor.

Screen Feeder
The Kraus K-Series screen feeder is a screen and feeder combination using a single- or double-deck screen with a brute force drive and a single electric vibrating motor. It is ideal for screening dry granular material from one inch down to 100-mesh particle size. The screen feeder can be flood fed and mounted directly below any size surge hopper and can screen super abrasive materials like silica sand and glass cullet or fine products such as granulated sugar. The replaceable screen deck can be constructed of a 500 Brinell abrasion-resistant steel or screen mesh with openings manufactured to your exact specification as might be desired.

Gravity Separator
The T-20 offers 20 sq ft of separation surface with high volumes of fluidizing air. The gravity separator offers superior separation performance in a rugged and reliable design. Simplified controls assure that machine settings will be trouble- and drift-free. Similar size material is fed onto a flat porous deck which is inclined in two directions. Low-pressure air is forced through the deck to fluidize and stratify the material bed. A vibrating action is applied to the deck to convey the heavier particles up the inclination of the deck. Lighter particles are partially suspended in the rising airflow and slide down the slope of the deck. The final result is a continuous gradation of material from the densest, largest particles to the lightest, smallest particles. Triple/S Dynamics, Dallas, TX 800-527-2116 www.sssdynamics.com
