Volumetric Feeders
Booth 1637 - For volumetric dry material feeding applications, Tuf-Flex series feeders handle a wide variety of fine powders, flakes, granules, chips, and pellets. Designed with a unique form of agitation, the feeders are manufactured with a Tuf-Flex vinyl hopper that is agitated on the exterior by two alternating paddles. The paddle action gently massages the material down into the metering screw, eliminating ratholing and bridging while conditioning material into a consistent bulk density. The helix flights are filled uniformly, resulting in high accuracy. The feeders are offered in model sizes accommodating feed rates from 0.000017 to 280 cu ft/hr.  Schenck AccuRate, Whitewater, WI 800-558-0184 www.accuratefeeders.com

Precision Rotary Feeders
Booth 2535 - These rotary feeders are precisely engineered with heavier barrels and can be rebuilt 1–3 times before needing replacement. They are manufactured in the United States in sizes up to 45 × 55 in., larger if custom made. The rotor blades are hard surfaced and tipped to give extended life, and the barrel material can be manufactured from mild steel, stainless steel, or alloy steel up to 500 Brinell to meet harsh application requirements. A trade-in allowance is offered for used feeders when they are replaced with a new precision rotary feeder. Precision Machine & Manufacturing Inc., Eugene, OR, 800 722-9841  www.premach.com

Feeder Material Flow Aid
Booth 1413 - The ActiFlow Smart bulk solids activator is a method to prevent bridging and rat-holing of cohesive bulk materials in stainless-steel hoppers without internal hopper agitation. The pharmaceutical ActiFlow design is a non-product contact device, consisting of a patent-pending vibratory drive and intelligent control unit, designed specifically to work with the company’s pharmaceutical line of gravimetric loss-in-weight feeders. In applications involving difficult flowing materials, ActiFlow eliminates the need for mechanical agitators with secondary motors and gearboxes, as well as the need for flexible side wall agitation devices or aeration pads. The patent-pending self-tuning algorithm implemented in the K-Tron Control Module (KCM) monitors the system, continuously adjusting the  frequency and amplitude of the ActiFlow to maintain flow within the hopper. In this manner, bridges and rat-holes are prevented before they can form.  K-Tron Process Group/K-Tron Feeders, Pitman, NJ 856-256-3265  www.ktronprocessgroup.com

Totally Enclosed Vibrating Feeder
Booth 3840 - This totally enclosed vibrating feeder with high trough sides and bolt-on covers eliminates the need for a static skirt with flexible connector seal. This eliminates downtime and maintenance associated with the removal, cleaning, and replacement of the flexible connector seal. Worn out flexible connector seals lead to dusting and difficult working conditions. This unit’s design essentially eliminates dusting. The feeder is constructed to  operate under highly abrasive conditions with little maintenance. Designed to match specific applications, it can discharge material over the trough end or through a bottom spout and the unit can be suspended or supported from below.  Carman Industries Inc., Jeffersonville, IN 800-456-7560  www.carmanindustries.com

Loss-in-Weight Batching System
This system is designed to be dust tight and virtually maintenance free. A bag access chamber, fitted with an automatic clamping system, ensures operators are not exposed to even the dustiest products. Product is discharged from a bulk bag directly to the GeoMate batching feeder, thereby minimizing headroom requirements. The GeoMate LIW feeder batches product in a pulse-less fashion to a belt conveyor. Batching accuracy to  +0.05% is achieved. The feeder operates with no moving parts and comes with a two-year warranty. 3Sigma, Charlotte, NC 704-846-1617 www.3sigma.biz

Vibratory Pan Feeder
Booth 1304 - The Kraus Stedi-Flo vibratory pan feeder is a rugged and heavy-duty design that can include a replaceable abrasion-resistant liner for extremely abrasive applications. It can be used for feeding almost any granular material or larger particle sizes such as abrasive silica sand, large glass cullet, gravel, abrasive ores and minerals to very fine granular powders. Applications include feeding from storage silos, bins, and hoppers to and from dryers, belt conveyors, bucket elevators, weigh hoppers, and continuous process applications such as feeding to a continuous mixer. The feeder can be operated with a variable speed controller or in a fixed rate application.  Kraus Vibratory Equipment, St. Paul, MN 651-484-2900  www.krausvibratory.com

Feeder with Integrated Control Valve
Booth 2520 – The CentriFeeder with Integrated Control Valve (ICV) accurately measures and controls the flow of any dry, free-flowing solid. Using a customizable touchscreen 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 unit is equipped with a Virtual Flow Stop function that stops flow with virtually no damage to your product. Eastern Instruments, Wilmington, NC 910-392-2490 www.easterninstruments.com
