76 / January 2021 powderbulk.com free-flowing materials into sam- ple dividers, mills, or mixers in a laboratory. Feeder's vibration is controlled by a microprocessor and conveys sample material out of the funnel over the V- or U-shaped stainless steel channel into the respective equipment. Feeder's flow- rate can be individually adjusted and the vibration amplitude pre- cisely controlled for uniform feeding of even the smallest quan- tities. Feeder is suitable for coarse and fine materials, which can be fed at rates between 1 and 2.5 grams per minute. Feeder's new control unit features a digital display of the set feedrate in percent and has a digital and RS232 interface. Fritsch Milling and Sizing Pittsboro, NC 919-229-0599 www.fritsch-international.com Pneumatic conveying line vacuum transports heavy materials in ordinary pipe Heavy Duty Threaded Line Vac pneumatic conveyor is an inline conveyor that transports high material volumes through ordi- nary pipe. Conveyor is for rugged, industrial applications and has a hardened alloy construction to help prevent premature wear when Iris valve is suitable for heavy particle, fine powder control Mitsumi iris valve is designed for medium-duty and regular operation in bulk solids processing both inline for flow control and for discharge functions. Valve is suitable for both heavy particles to fine powders, including in sanitary applications. Valve uses a flexible sleeve, high- strength rope, and durable metal casing to provide control over a wide range of bulk solids process- ing. Valve's flexible sleeve is the only valve part that comes into contact with the material inline, so, for example, a material like metal flakes can't contaminate the output. Valve is offered in models that allow unrestricted, partial, or automated flow control. AAAmachine, Des Plaines, IL 847-481-8264 www.aaamachine.com Lab-sized vibratory feeder's flowrate can be individually adjusted Laborette 24 vibratory feeder is for automatic, uniform feeding of PRODUCT NEWS Screwfeeder's dual- helix design delivers fast, accurate feeding Model TSF twin screwfeeder is for precise batching and weigh- ing applications. Screwfeeder's dual-helix design combines fast, high-volume filling with accurate dribble flow at the cycle's end. Screwfeeder's compact design is suitable for applications with lim- ited space that would prohibit multiple individual screw units. Screwfeeder's two helixes (1.5 and 4 inches in diameter) are mounted on an 18-by-22-inch hopper. Screw- feeder's helixes are rated to handle material at 17 cubic feet and 283 cubic feet per hour, respectively, when operating at maximum rpm with 100 percent efficient convey- able material and no slippage.
