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 lilt time allows for accurate metering of the material being discharged. Weigh frames and controllers are available for accurate batching 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.

Load cells convert any tank, bin, hopper, silo, or blender into a precision weigh system. From complex batch/blend systems to simple shipping/receiving scales, BLH systems measure, record, and control every weight-related process throughout the plant. Easy digital interface options integrate equipment with Allen-Bradley, Schneider Automation, Fisher Pro Vox, Honeywell TDC 3000, GE Series 90 and Siemens distributed control systems.

WALKER MAGNETICS

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.

Cranes range from 0.5- to 15-ton capacities with heights from 4 to 24 ft and spans to 35 ft. Available with 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, R J-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.

THE WITTE CO., INC.

Pellet classifiers designed specifically to remove fines and oversize from plastic pellets. Units available with cooling, air separation and drying capabilities. All units easy to disassemble and clean. Capacities from 150 to 30,000 lb/hr.

WITTMANN, INC.

Pneumatic materials-handling systems include vacuum loaders, railcar unloaders and unloading systems, storage hoppers and silos, blenders (weigh and volumetric), additive feeders and complete turnkey plant systems. Quality engineering and standard features guarantee maximum efficiency and minimum downtime. Off-the-shelf controls allow for individual systems or total plant control for fully automated materials-handling solutions. Simple modular designs allow for cost-effective custom applications solutions.

THE YOUNG INDUSTRIES, INC.

Pneumatic and mechanical conveying equipment and systems include low-velocity dense-phase designs. Systems handle a range of products including resins, pigments, pellets, powders, modifiers and fillers. Capacities range from 1000 to 200,000 lb/hr. Equipment is custom-designed and can be constructed in carbon steel, stainless steel, aluminum or alloys. Multiphase dense-phase pneumatic conveyor provides gentle low-velocity conveying when product degradation must be avoided. Offered in batch or continuous arrangements.

TransVair dilute-phase conveying systems convey a range of materials using positive or negative pressure as well as combination negative/positive pressure. Closed-loop dilute-phase conveying for hazardous chemicals, hygroscopic materials and for edge trim conveying in combination with rotary knife cutters, reduction mills and machinery requiring an air draw. Systems can be designed to unload railcars, load and unload bulk bags, silo loading and unloading, mixing systems, in-plant transfer, regrind conveying, automated product weighing as well as complete compounding projects.

TransVair mechanical conveyor is a high capacity, low hp, low-cost and dust-free conveyor. Unit can handle a range of products and is efficient with pigments and other difficult-to-handle materials. Unit is cost-effective for bulk bag unloading systems, mixing systems, and automated product weighing applications.

In addition to lab testing, process design, turnkey installation and startup other bulk material-handling equipment/components include airlock valves, self-contained bag dump stations, filters, diverter valves, blower packages, blenders, hoppers and control panels. Equipment designed to process and handling requirements and can be fabricated to the ASME Codes and National Board U and UM stamped.
