In response to customer demand for finer cut points and improved operation, several new features have been incorporated into the unit. The Acucut Model NGA-12 now includes the following: classifier speeds have been increased to as high as 8000 rpm, a 33% increase, to produce finer cut points; a high-efficiency cyclone collector for improved collection efficiency; and a dust collector with pleated filter elements for collecting ultrafine particles that by-pass the cyclone. The dust collector is available with removable collection canister or manual valve and collection canister. Other features include: updated PLC-based controls with Operator Interface Terminal and static graphical display and new ergonomic design for easier accessibility and clean-ability. Micron Powder Systems, Summit, NJ 908-273-6360

82424.tifMultifunctional Classifier
The DC Classifier is a multifunctional unit designed to dry, cool, and classify all in one machine. Developed specifically for the plastics industry, it is ideal for any dry application requiring one, two, or all three of its intended functions: drying, cooling, and classifying. The unit utilizes either positive or negative air flow to draw moisture and heat away from the particulates to dry or cool the material. The material continues through the machine to the classification stages where oversize and fine particles can be removed. It was designed with modular decks for easy removal for cleaning in-between process changes when more than one material type or color is processed in the same machine. Sweco, Florence, KY 859-371-4360

82425.tifCompact Sifter
The high-capacity, compact FlexSift S10 is easily vertically integrated into processes and overcomes many of the typical problematic product flow bottlenecks associated with traditional sifting technologies. The S10 security screens, de-lumps, and discharges all without the need for feeder equipment, allowing for higher capacities and better product flow than large conventional sifters. It is safe and simple to disassemble, and has a minimal number of parts, enabling easier cleanup, quicker screen maintenance, and minimal down-time. The S10’s compact, light, and vibration-free design enables it to be readily coupled with most bulk bag unloaders and mixer dischargers, making space and support frame requirements minor in comparison to conventional sifters. The vibration-free design equates to low noise, less power, minimal maintenance, and virtually eliminates the unwanted size reduction and agglomeration that is typical with traditional sifters. Quadro Engineering Corp., Waterloo, ON Canada 519-884-9660

82418.tifBox-Container Dumper
The Tip-Tite box-container dumper forms a dust-tight seal between the container and the equipment, tips the container, and discharges bulk material through a chute at controlled rates. It accommodates Gaylords and other boxes, including truncated corner boxes, from 36 to 48 in. on a side and 39 to 44 in. overall height. The container platform is raised by a single hydraulic cylinder, creating a dust-tight seal between the top edge of a box (or rim of a drum) and the underside of the containment hood. Twin hydraulic cylinders then pivot the platform-hood assembly, with container intact, to 45, 60, or 90 ° beyond horizontal, including a motion-dampening feature at the termination of container rotation. Flexicon Corp., Bethlehem, PA  888-353-9426
