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 conveyor belt. A unit is considered a dense phase conveying system if it has air pressure ratings about 15 PSIG.
So what are the reasons behind these high-pressure systems? Most conveyor lines use a large amount of air to move smaller materials along a conveyor. This type of conveyor system is somewhat inefficient for larger objects with a higher weight. Using a smaller amount of air in a specifically calculated process helps the conveyor move the materials along using less energy in a more effective manner.
Most pneumatic conveyors are used to transfer dry materials from one place to another, sometimes through pipes that push the materials up into the air or across long distances. Because of this, the amount of energy that each factory uses to transfer the goods quickly adds up. Higher energy use leads to higher operational costs for the factory. This is one reason why the choice of a conveyor type is extremely important. Using a system that can convey materials from one place to another using less energy will end up saving the company thousands of dollars in the end. This is why many companies are turning to the use of dense phase conveyors rather than low-pressure systems. In addition to saving money, using this system also leads to less pollution and waste because the air pressure is more focused and helps control the movement of the material better. The machines can also last longer because there is less overall wear on the blowers and other components of the conveying system.
