Single-Drive Feeder

Tecnetics IndustriesThe Tecweigh QC10 single-drive feeder couples a Flex-Feed polyurethane hopper with an opening in the bottom and the ability to agitate the hopper without driving the auger. When material needs to be changed, simply stop the feeder and place a reclaim container underneath. Then open the bottom discharge slide gate (or remove the plug) and run the drive motor in reverse. Tecnetics Industries Inc., St. Paul, MN 800-536-4880 www.tecweigh.com

Volumetric Tube Feeder

HAFThe Series VTF volumetric tube feeder is available in a range of sizes from 3 to 9 in. in diameter and is capable of feed rates to 350 lb/min. A wide range of inlet to discharge centers allows for fitment into most processes. Features include a sleek round tube design with extended keel inlet that allows for smooth bridge free flow to feed zone. Oversized discharge eliminates discharge jams. A rear-mounted hollow shaft drive provides easy auger removal and cleaning. The discharge end includes a tool-free clamp and cover for fast access. The vacuum-tight design makes this feeder suitable for mounting directly to a vacuum receiver without the need for an airlock, supports, or flexible connections. HAF Equipment Inc., Centerville, MN 651-653-5098 www.hafequipment.com

Feeder/Screener

This dynamically balanced, natural frequency, or electro-mechanical vibratory screener feeder conveys product while classifying to specific particle distribution curves. Units can be volumetric flow rate feed design. Construction can be suited to chemical, food, dairy, and pharmaceutical industries. Machine and Process Design Inc., Anoka, MN 763-427-9991 www.mpd-inc.com

High-Precision Feeder

The Dyna-Slide high-precision air-activated feeder combines low-pressure compressed air and gravity to fluidize and convey most fine dry granular materials. The low-profile design is totally enclosed and dust-free, making it ideal for conveying from silos to weigh scales, hoppers to weigh scales, and feeding from multiple discharge points to mixers. The high-energy efficiency and ease of installation contribute to a cost-effective solution to conveying, even over long distances. With Dribble Feed Control, the unit will provide up to a 100:1 turndown ratio when feeding most fine (30 mesh to sub-micron) fludizable powders and granules.

Recirculating Spreader-Feeder

Flexicon Corp.This recirculating spreader-feeder evenly distributes powder and bulk coatings onto food products as they pass between the unit’s longitudinal discharge hopper and its lower collection hopper. The mobile unit is positioned so a wire conveyor belt with items to be coated passes above the unit’s lower collection hopper, as a uniform curtain of the coating material descends from the upper discharge hopper that has multiple ports to apportion material across its length. A small-diameter rotating agitator promotes uniform discharge through an adjustable screen that spans a gap along the hopper bottom. A centerless auger along the bottom of the longitudinal collection hopper feeds material into the intake adapter of a side-mounted flexible screw conveyor. This elevates the material into a horizontally oriented conveyor positioned above a longitudinal discharge hopper. Flexicon Corp., Bethlehem, PA 888-353-9426 www.flexicon.com

Bulk Material Feeders

These bulk material feeders provide accurately measured introduction of material into processing and packaging operations. Regardless of material characteristics, the feeders deliver a consistent and repeatable feed of material, whether in continuous flow for pre-feed or feed applications, or in intermittent flow for batching applications. Integrated automation pushes controls functionality farther out and deeper into feeder operations to optimize total line throughput and deliver a standard, system-wide, data report from the control layer. Feeder control, communication, sensing, monitoring, and reporting are driven by a single, system-wide, touch screen HMI. National Bulk Equipment Inc., Holland, MI 616-399-2220 www.nbe-inc.com
