Pneumatic Air-Vey Magnets

Puritan Magnetics Inc.Air-Vey magnets remove ferrous contaminants from products in dilute-phase pneumatic conveying systems operating at 15 psi or less. These units are used to ensure product purity and protect process equipment. The flow through area of the housing is engineered to maintain the same product velocity with no appreciable drop in pressure. The magnets easily install in horizontal, vertical, or angled positions with compression type couplings or weld in place. Inside the stainless-steel housing is a powerful cylindrical shaped magnet with a cone shaped nose. As material enters the housing, the nose cone diverts the material around the cylindrical magnet where it passes through the magnetic field and ferrous contaminants are drawn to the magnetic surface. Ferrous contaminants are safely held in place as the cleaned product exits out the opposite end of the housing. Puritan Magnetics Inc. Oxford, MI 248-628-3808 www.puritanmagnetics.com


These transporters are designed to handle abrasive, fragile, sticky, and high-temperature materials in a pneumatic conveying system. The transporter receives material from supplies and then conveys to one or more locations. All transporters are shipped fully assembled and tested. Inlet and outlet valves are installed, compressed air piping is completed to a single air connection, and all electrical solenoids, level controls, and pressure transmitters are wired to a terminal strip in a junction box.  Whirl-Air-Flow, Big Lake, MN 800-373-3461 www.whirlair.com

Heavy-Duty Pump

pneumatic conveyingThe Fuller-Kinyon pump is ideal for conveying fine powders without risk of blowback. A material seal is formed when product is forced against the counterweighted flapper valve preventing convey-air leakage back through the screw. One moving part means less maintenance and reliability in the most demanding environments. The pump operates with lines pressures up to 30 psig. Features include heavy-duty construction, ease of maintenance, design simplicity, cost effectiveness, ability to handle high capacities, fuel efficiency, and low power consumption. FLSmidth, Bethlehem, PA 610-264-600 www.flsmidth.com

Dense-Phase Pneumatic Conveying System

pneumatic conveyingA key feature of this dense-phase conveying system is the exclusive air management system. By using a pressure control regulator, airflow control orifice, and bypass valve, total air flow to the system and product-to-air ratio are automatically controlled at the vessel. When air flow and product-to-air ratio are not accurately controlled, boosters or trace air lines are required. Not only are they expensive to purchase and install, but will add air to the system. Added air creates higher energy requirements and increased line velocity. Smoot, a division of Magnum Systems, Kansas City, KS 800-748-7000 www.magnumsystems.com

Pressure Blowers

pneumatic conveyingTo fill the need for greater pressures and volume, Chicago Blower developed a series of high-capacity blowers to fulfill higher filtration requirements for dense solid media. The blowers convey a variety of materials, as well as cool and aerate, and are especially suited for the most advanced pollution control systems. Features include a lightweight aluminum alloy wheel designed to reduce motor loads and decrease vibration. Chicago Blower Corp., Glendale Heights, IL 630-858-2600 www.chicagoblower.com

Dual-Blower Railcar Unload System

pneumatic conveyingThe vacuum-pressure rail unload system unloads powder, pellet, and granular material from railcars at conveying rates in excess of 100,000 lb/hr. Using separate vacuum and pressure blowers, the system unloads material from the railcar at higher conveying rates and for longer conveying distances. A vacuum blower draws material from the railcar to a self-cleaning filter receiver that separates the product from the conveying air. Mounted below the receiver is an Aerolock rotary valve that meters the product into the pressure side of the system for final delivery to storage. Dual-blower systems are available in 3–10-in. line sizes and include a control panel, properly-sized blowers, railcar adapter kit, and hoses.

Pneumatic Line Housing

pneumatic conveyingIMI introduces the pneumatic line housing (PLH). Instead of a single, center-flow cartridge circuit, the PLH incorporates a series of 1-in. diam. 50 MGOe Rare Earth tubes on staggered centers. This ensures that all product has repeated contact with the magnets. The holding strength of the bullet magnet has been improved with a newly introduced stripper collar that is used to wipe metal contamination from the magnet. Industrial Magnetics Inc., Boyne City, MI 231-348-5730 www.magnetics.com

Pneumatic Conveying Systems

Each of this company’s 16 pneumatic conveying concepts has it own set of operating characteristics for pressure, conveying line velocity, efficiency, and performance. Because each material to be conveyed reacts differently under a given set of operating conditions, it is critical to match the system operating characteristics to the material to be conveyed in order to achieve the most desired conveying performance and to provide the best value. Each system has the ability to convey at almost any conveying velocity desired to suit a given material to be conveyed. Conveying capacities range from just a few hundred pounds of material per hour up to 500 tn/hr, with conveying distances exceeding 6000 ft. Dynamic Air Inc., St. Paul, MN 651-484-2900 www.dynamicair.com/systems.html

Dense-Phase Pneumatic Conveying System

The dense-flow system differs from many of its competitors with the absence of air boosters along the pipeline. This system can achieve equal or greater results in many instances without the use of boosters. Some of the advantages to not having boosters include lower air consumption, lower installation costs, less maintenance, less “wear and tear” on the system, and less spare parts inventory. The system simplifies complex conveying problems. J.D.B Dense Flow Inc., Palm Harbor, FL 800-822-3569 www.jdbdenseflow.com

Pneumatic Screw Pump

pneumatic conveyingThe pneumatic screw pump is a heavy-duty dry materials injection pump designed to feed dry pulverized material into a pneumatic conveying line. It can handle highly abrasive, friable, or very fine powders. Unlike rotary airlocks that require tight clearances to seal against conveying air, this pump uses the material to form the seal. Other benefits include increased conveying rates with less air, no blowback, even when running empty, increased wear resistance to abrasive materials, low profile, longer bearing life with fewer system shutdowns, and overall reduced operating and maintenance costs.
