102330.tifVibratory Conveyor Monitoring System
SmartArm is a wireless performance monitoring system for Iso-Flo vibratory conveyors that enables users to monitor asset or equipment shaker condition at any computer workstation. The system measures and reports speed and stroke to provide real-time analysis of shaker function, line-flow conditions, and trends at-a-glance. The SmartArm client also shows an alert when speed or stroke are out of tolerance. Empowering the shift from traditional time-based preventive maintenance to condition-based predictive maintenance, SmartArm not only prevents downtime and reduces labor, it also provides the opportunity to improve process efficiencies. Key Technology Inc., Walla Walla, WA 509-529-2161 www.key.net

102331.tifFlexible Screw Conveyor
This Helix flexible screw conveyor is specifically designed to ensure food safety when processing sluggish powder and bulk solid ingredients. The Helix Hi/Lo flexible screw conveyor now features an optional mass-flow hopper that encourages discharge of sluggish or non-free flowing ingredients without the need for separate in-hopper agitation. The hopper’s steep, conical shape successfully moves challenging materials, such as those with high moisture or fat content. Optional external vibration can be added to assist with material flow. The mass-flow hopper eliminates the need to use an agitator, which utilizes seals that require a good deal of attention to clean. The design allows a single worker to safely and easily handle washdowns, auger changeouts, and servicing from floor level. An electric actuator automatically lowers the auger to an easy-to-access height. Exclusive T-handle couplings allow disassembly in minutes.  Hapman, Kalamazoo, MI 269-382-8228 www.hapman.com

102333.tifMultiple-Conveyor System
Multiple mechanical conveying methods are integrated into this automated bulk material handling system to move highly fibrous, non free-flowing material from infeed to discharge, from material conditioning to supply metering, and from metering to downstream processing. At infeed, a chain-driven live roller conveyor and an integrated, 3000-lb-capacity pop-up chain transfer conveyor move gaylords into position for automatic alignment with the gaylord dumper lift carriage. From the material conditioning stage, a 2500-lb/hr feed rate, continuous-duty weigh belt conveyor ensures accurate, reliable material supply. From material weighing an inclined, boxed-cleat belt conveyor delivers material to downstream processes at a final drive speed of up to 30 ft/min. National Bulk Equipment Inc., Holland, MI  616-399-2220  www.nbe-inc.com

Standard designs are easily customized to meet your application requirements.  General Kinematics Corp., Crystal Lake, IL 815-455-3222  www.gkprocess.com

102341.tifTilt-Down Portable Bulk Conveyor
This bulk conveyor with a tilt-down portable base fits through tight spaces and provides easy access for removal of the flexible screw. Its reduced footprint enables the caster-mounted frame to maneuver through narrow aisles and around corners. With the hopper, support boom, and conveyor assembly tilted down, the unit fits through standard doorways and orients the conveyor tube horizontally, allowing the flexible screw to be removed easily for thorough cleaning and inspection. Each unit is custom configured according to the discharge height, tilt-down height, discharge overhang, and overall size parameters of individual applications. The hopper, which is equipped with a hinged lid, feeds a flexible screw conveyor that transports bulk ingredients ranging from sub-micron powders to large pellets. The enclosed conveyor tube prevents product and plant contamination, while the gentle rolling action of material being conveyed prevents the separation of blends. The rugged inner screw is the only moving part contacting material, resulting in reduced maintenance and increased reliability. Flexicon Corp., Bethlehem, PA 888-353-9426 www.flexicon.com
