MATCON USA, INC.

Matcon Intermediate Bulk Container (IBC) systems discharge materials from portable bulk-storage containers. Using Matcon's patented discharger/valve principle, each IBC has an "in-bin" cone valve at its discharge outlet. When the IBC is placed on its mating discharge station, the inverted cone connects with a probe within the station. Probe pneumatically raises the cone into the material and vibrates it, causing the material to break up and flow through the annular gap created by the lifted cone. Varying the cone's height and lift time allows for accurate metering of the material being discharged. Weigh frames and controllers are available for accurate hatching or continuous feeding. Because the cone and probe create a dust-tight seal, IBCs can be filled, transported, and discharged with no dust contamination. Partially filled IBCs can be removed from the station with total containment of product. Containers are of stainless steel, mild steel or polyethylene with capacities in excess of 100 cu ft.

Wide range of modular vacuum receivers allows flexibility in handling material from small injection molding machines to high-throughput extrusion lines. Railcar unloaders with single- or double-blower vacuum/pressure systems accommodate conveying distances exceeding 1000 ft.

Echo control system features a truly distributive control and differs from other microprocessor and PLC controllers where a central panel controls an entire system. It supplies an independent module at each device location (pump, vacuum chamber, blender, etc.). These modules, though independent, are in constant communication with each other via a network link. By operating in a system fail-safe manner, Echo system maintains its integrity in the event of a circuit failure, unlike other PLC and microprocessor controllers where the entire system fails. Simple two-wire communications cable is the only requirement to link devices, greatly reducing the cost of electrical installation and hardware. Modular and flexible, additional devices can be added as the need for manufacturing expansion increases. Total system control from any Smart Station location is featured. Because of the modular design, a central annunciator and panel is supplied for total system overview. A diagnostic module, Doctor Diagnostics, interfaces with each device on the Echo system, monitoring critical system functions, and will try to correct any malfunction.

Quick-material-change systems facilitate rapid changeover. Material or color changes, including hygroscopic materials, can be accomplished in a short time. Broad range of configurations available from local beside-the-press systems to central systems. Material changeover operation can be manual or fully automatic, using a specially designed QMC valve. QMC-I microprocessor controls an entire system, directing the conveyance of materials from as many as 16 different sources to 12 different destinations.

Line of pneumatic conveying systems for bulk solids at up to 100,000 lb/hr. Proprietary designs of diverter valves, low- and high-pressure rotary valves, silo blenders, air classifiers, and other ancillary equipment.

O.S. WALKER CO.

Permanent and electromagnetic separation equipment includes magnetic head pulleys for use in conveyors; permanent and electro-suspended magnets for automatic removal of ferrous material; and permanent and electromagnetic drum separators. Plate and grate magnets used in chute applications with special automatic removal devices. Eddy-current separators for nonferrous metallic removal.

B.E. WALLACE PRODUCT CORP.

Gantry cranes and accessories load and unload everything from raw materials to finished products to and from storage units, trucks, railroad cars, and barges. Cranes range from 1/2- to 15-ton capacities with heights from 4 to 24 ft and spans to 35 ft. Available wih adjustable or fixed heights and constructed of aluminum alloy, steel, or a combination.

WALTON/STOUT, INC.

Pneumatic rail unload and machine-load conveying systems for powder or pellets, including vacuum pump packages, filter systems, vacuum-receiver level-control switches, RJ-5 powder filters, virgin/regrind receivers, and pellet receivers. Standard options include sound enclosure, stainless-steel construction, rates to 30,000 lb/hr, internal check valves, dual proportioning valves, and dual inlet valves. Also microprocessor-controlled weigh and volumetric blenders to 5000 lb/hr.

Dense-phase pneumatic conveyors move products at low velocities and high quantities over long distances without product degradation, stringers, fines, heat build-up, or other types of problems incurred in dilute-type conveying.

Construction engineering, turnkey services, and installation.

JERVIS B. WEBB CO.

Integrated materials-handling systems can include computer-controlled interfacing, automated storage and retrieval systems, automatic guided vehicles, belt and roller conveyors, power-and-free conveyors, screw conveyors, and more. Provides concept engineering, computer simulation, training, maintenance monitoring, and turnkey commissioning.

WEBB TECHNOLOGIES LTD.

Pneumatic hopper loaders and ratio loaders for up to 450 lb/hr of pellets. Loaders do not require a hopper on the process machine.

WEIGH-TRONIX, INC.

Industrial scales include counting scales, bench scales, checkweighers, deck scales, lift-track scales, static or in-motion rail scales, bin/tank/hopper scales, conveyor scales, and truck and crane scales. All major components include strain gauges, load cells, and patented weigh bars. ISO 9001 certified.

WHITLOCK See AEC/Whitlock.

THE WITTE CO., INC.

Pellet classifiers designed specifically for plastic pellets remove "oversize" by screening either once or twice for improved short/long removal. Fines removed using wire mesh and/or high-velocity air for statically held fines and ribbons. Available in many sizes from 300 to 30,000 lb/hr.

THE YOUNG INDUSTRIES, INC.

Pneumatic materials-handling systems include blow-tank (medium-velocity) system for abrasive, heat-sensitive or friable products. Capacities range from 7.5 to 500 cu ft. Systems are constructed of carbon steel, stainless steel, or aluminum.

TransVair dense-phase conveying system provides low velocity for powders and granulates when product degradation must be avoided. Powered by compressed air and automatically controlled to deliver up to 6000 lb/hr.

Closed-loop dilute-phase conveying for hazardous chemicals, hygroscopic materials and dusty products adaptable to edge-trim conveying and used with rotary knife cutters, reduction mills, and machinery requiring an air draw.

Centrifugal-blower dilute-phase system can be positive-pressure, negative-pressure, negative/positive pressure, or closed-loop system. Limited in static pressure capability for short distances.

Combination negative/pressure dilute-phase system for multiple material-entry and delivery points. Applications include drawing materials from several points for batching before processing, and unloading from several points, such as from railcars, with delivery to bulk storage.

Negative-pressure dilute-phase system is especially suitable for conveying toxic material from a number of inlet points to a single discharge point.

Positive-pressure dilute-phase system is designed for conveying a product from a single entry point to one or more destination points. System uses minimum air quantity to move material long distances.
