Transporter Diagram

Whirl-Air Transporters are designed to transport any flowable material in a pneumatic conveying system. The transporter unit receives materials like powders and dry granulars from bulk supply such as silos, trucks, or rail cars. The system conveys the bulk materials to one or more destination points. The transporters operate on a cycling system and have virtually no moving parts. Operational functions of fill, pressurize, convey, and repeat are all enabled by valves.

Each of our transporters is built customer and product specific in terms of capacity, cycle rate and material throughput. Dependent on the material being conveyed, a specific model such as BF or ED will be used. We also use special system designs like Continuous Conveying Systems and "Keep Full" Conveying Systems for different applications.

Capabilities

Typical Materials Handled

Dry granulars
Fine specialty powders

Sticky materials

Conveying Process Steps

 View 		1. Unit is fiilled with conveyable bulk material by gravity. Inlet and vent valves open allowing transporter to fill through top and vent air to escape to the conveying line.

2. The vessel is pressurized with compressed air or gas to build conveying force. Inlet and vent valves close when material reaches full sensor. Vessel is pressurized through the top and/or through air pads or nozzles, depending on the material being conveyed.

3. When the correct conveying pressure is achieved, the material is conveyed to the destination.

4. The conveying cycle is complete when the transporter is empty. The fill cycle is then repeated. Purges can be added to clean out the lines or the lines can remain full on continuous systems.

Cycle Rates

Typically designed to cycle up to 20 times per hour. Special models can achieve considerably higher cycle rates dependent on the requirements of the application.

Benefits

  • Versatility - able to handle abrasive, fragile, sticky and high temperature products.
  • High Performance - conveys longer distances than dilute-phase systems.
  • High Capacity - capable of achieving higher capacities in a given line size than dilute phase systems.
  • Efficiency - Lower air/gas consumption than dilute phase systems.
  • Low Maintenace & Easy To Operate - Whirl-Air Transporters typically convey using easily dried and cooled compressed air.

    • Unit Construction

    		Each transporter is custom built in a broad size and configuration range without additional cost. The units are constructed to take all factors into consideration:
  • Floor space
  • Capacity
  • Cycle rates
  • Integration
  • Throughput

    The units are well suited for the broadest range of products since they are constructed in a wide array of materials:
  • Carbon steel
  • Stainless steel
  • Lined steel
  • Coated steel
  • Polished steel

    • System Types

  • Whirl-Air Standard Systems - Suitable to most applications, they convey most free flowing materials in a fill, close, seal, pressurize, and convey cycle. The cycle ends when both the transporter and conveying line have been fully evacuated. Full evacuation is detected by a pressure sensor. In standard configurations, the system is capable of up to twenty full cycles per hour and employs a fill, close, pressurize, convey sequence - applicable to most materials and rates.

  • Whirl-Air Continuous Conveying Systems - For long runs, or high throughput rates, they use dual transporters to obtain peak performance. In this system, one transporter fills and pressurizes while a second transporter conveys. This configuration ensures a continuous flow of material and is particularly well suited to conveying runs often exceeding 1,000 feet.

  • Whirl-Air "Keep Full" Conveying Systems - These systems are designed for use with materials where achieving zero breakage is a concern. "Keep Full" systems minimize turbulence within the conveying line by evacuating only the transporter before beginning a new cycle. A sensor within the transporter detects empty. Compressed air inside the transporter is then vented to a dust collector prior to starting a new conveying cycle.

    • Special Handling Features

     View     		Our Model BF transporters are used to transport the widest range of flowable bulk materials. To match transport requirements to the application, Model BF transporters can be outfitted with special equipment for smooth transport of materials with particular handling characteristics. These may include special nozzles, air injection, and special feeding or evacuation fitments to meet precise throughput requirements.

    Configuration Design

     View     		Every transporter is designed with consideration to the unique handling characteristics of the product being conveyed. Standard configurations of the Model BF Transporter include:
  • Air Pad Bottom - Powders
  • Basic - Dry granulars
  • Basic with Air Pads - Specialty powders
  • Basic with Nozzles - Sticky materials
  • Cone Gate with Nozzles - Foundry molding sand

    • Quality

  • Whirl-Air-Flow is an ASME, Section XIII Code certified pressure vessel manufacturer.
  • Every transporter is custom built from the ground up to the specifications of the application for which it is designed.
  • Whirl-Air has complete control over every aspect of product quality and delivery.

    • After Market Services

    		The Whirl-Air-Flow commitment to customer satisfaction continues well after your system is up and running.
  • We offer all the replacement parts necessary to maintain the high efficiency of your systems.
  • We have factory trained service technicians available to trouble shoot system problems as well as to train your maintenance personnel in efficient system operation.
  • If your future needs require system modification, our engineering department is available to assist you in all phases.

    • Shipping & Installation

    		All transporters are shipped fully assembled. Inlet and outlet valves are installed and compressed air piping is completed to a single air source connection. Electrical solenoids, level controls and pressure transmitters are wired to a terminal strip in a NEMA rated junction box. These extra features reduce installation cost and wiring time, resulting in faster start-up. We will configure transporters to customer installation specifications prior to shipping.
