97629.tifRotary Airlock Feeder
The Dust Collector Series (DCS) rotary airlock feeder is an economical valve suited for general use under dust collectors, cyclones, and hoppers. This feeder has eight-blade rotors, precision machining, and rugged cast iron housing for efficient operation. In a case where pressure differential exists, such as when feeding pneumatic conveying lines, this unit is best suited for feeding the material accordingly. These particular airlocks maintain the highest level of performance for an extended period of time. The Quick-Take-Apart Series (QTA) rotary airlock feeder is made for applications where frequent removal of the valve internals is required. When encountering alumina, coke, fly ash, glass frit, and other highly abrasive products, the Ceramic Series rotary airlock feeder sustains its durability and achieves at least 3-5 times longer life compared with chrome and Ni-hard valves.  Prater-Sterling, Bolingbrook, IL  630-759-9595 www.prater-sterling.com

97631.tifMass Flow Meter
The CentriFeeder with Integrated Control Valve (ICV) accurately measures and controls the flow of any dry, free-flowing solid. Using a highly customizable touch screen HMI equipped with an integrated Servo (low rpm, AC, brushless), a PID control loop is established to control the ICV feeding the patented CentriFlow meter. For precise measurement and control, an Integral Linear Position Sensor is used to regulate the blade’s position to within 1 part in 1000 (based on stroke). The blade’s movement can then be monitored via the CentriView electronics, or read manually via the mechanical indicator on the exterior of the valve. For delicate products, the CentriFeeder with ICV is equipped with a Virtual Flow Stop function that stops flow with virtually no damage to product.  Eastern Instruments, Wilmington, NC 910-392-2490  www.easterninstruments.com

Size/Density Separator
The Vibro-Air size/density separator employs vibratory screening to remove undersize particles, and airflow to simultaneously remove low bulk density materials. It is said to efficiently separate: fines and chaff from grain products; fines, angel hair, strands, and film scrap from plastic pellets/regrind; fibers, saw dust, and wood flour from wood chips/shavings; and other undersize and low-bulk density matter from on-size products. Material fed through a port on the unit’s hood cascades over a series of strategically placed internal trays and ultimately onto a vibrating, fine mesh screen that moves on-size material in controlled flow patterns toward and through a discharge port at the screen’s periphery. Heavier fines and a portion of the lighter fines pass through the screen onto a chute leading to a lower discharge spout. Simultaneously, air drawn into the base of the air-tight chamber flows upward, drawing the balance of low-density fines, along with airborne dust, fibers, and strands, into an airstream that increases in velocity (as the hood tapers) before venting to a cyclone and/or dust collector. Kason Corp., Millburn, NJ 973-467-8140 www.kason.com
