  • Considerations for Switching to Dense Phase Conveyors

    A dense phase conveying system is simply another name for a high-pressure conveying system. High pressure systems are necessary for certain industrial processes to push objects along the conveyor using positive pressure to move the objects along at a lower velocity. The reason dense phase is a high-pressure, low-velocity system is due to the air to weight ratio of the objects carried along by the conveyor. Typically, the high pressure systems are used to move heavier objects along the conveyor, which leads to a lower velocity of the items on...

  • The Advantages of Dense Phase Conveying

    Dense phase conveying was designed to handle bulk materials and heavy, abrasive objects. Typically, the conveyance method is used with rough manufacturing materials, such as rocks, loose materials, and other heavy, bulk equipment and particles. Most commonly, dense phase conveying is used to transport friable, agglomerated, heavy, or blended materials from place to place. Without this form of dense bulk conveying, many manufacturing plants would have to come up with other, less-effective methods to handle large amounts of heavy and abrasive raw materials. Although there are other methods of conveying...

  • Transporting Salt with Dense-Phase Conveying

    The transportation of salt is an issue for many factories, but is a topic that is often overlooked. It is difficult to find the perfect conveyance method for salt, because salt has unique properties unlike other raw granular materials. One solution for transporting salt from place to place is a dilute-phase vacuum system. This system has some problems with the properties of salt, however. One of the main problems with this conveyance system is that the air pressure was too high for the salt particles. The pressure from the vacuum...

  • The Whimsical Side of Pneumatic Conveyors

    Valentine's Day is one time of the year many of us expect chocolate. With such a wide variety of chocolate shapes and options available, you can expect there to be many methods utilized to create them. Recalling a classic childhood chocolate film, Willy Wonka and the Chocolate Factory, you may remember how the conveyor belts ran the candy down the processing line. While a traditional conveyor would use motors to move the product from one point to another, pneumatic conveyors are able to use an environmentally friendly form of power....

Industry Information

Dense Phase Conveying

Dense phase conveying, also referred to as non-suspension flow, is one of the two main methods of pneumatic conveying. The other method is dilute phase conveying, and the main points of difference between the two are pressure, the solids' properties and the rate of conveying speed. In particular, dense phase conveying deals with the transportation of abrasive, friable or heavy materials such as sands, soils, minerals, food, paper scraps and rocks.

Dense phase conveyors push materials through at a fairly low velocity with a low air-to-material ratio. Often, dense phase conveyors use an air compressor to generate high pressure levels to move materials through the system at a general average of 275 feet per minute. Typical industries that benefit from dilute phase conveyors include pharmaceutical, chemical and food processing, foundry, mining, plastics and cement. Since dense phase conveying is ideal for moving large quantities of materials, it is often used in bulk material handling applications. However, dilute phase conveying may also be used if the materials being conveyed are both light-weight and non-abrasive.

A dense phase conveyor is an enclosed tubular conveyor that is operated through air pressure and is typically gravity or vacuum-loaded while discharging materials from the bottom; however, there are several different dense phase conveyor designs. The bottom-discharge design in particular lends itself so well to dense phase conveying because the materials being conveyed are so densely concentrated that they will naturally deposit at the bottom. Movement within gravity-loaded dense phase conveyors is typically generated by a blower at the starting end of the conveyor, although vacuum-loaded dense phase conveyors pull products through using a vacuum at the conveyor's destination. When the material being conveyed is fluidized, it deposits at the bottom much like a deposit of liquid and is dragged, or pushed, along the bottom. In dense phase conveying, there are two different manners of flow: moving-bed flow and plug flow. Moving-bed flow occurs when the material is conveyed along the bottom of the conveyor pipeline, whereas plug flow occurs when the material is conveyed in units, called plugs or slugs, which are separated by air gaps rather than one fluid body.
