.jpg) | Dense Phase Pneumatic Conveying Dense phase pneumatic conveying utilizes a small amount of air at a relatively high pressure (above 15 PSIG) to move powdered and granular bulk materials through an enclosed convey line. Due to the low conveying velocity (200 to 3,000 feet per minute) produced by a Dense Phase system, materials are gently pushed through the convey line in controlled "slugs." As a result, Dense Phase is preferred for moving mixed batches or materials that may be abrasive, fragile, heavy, or hygroscopic in nature. The efficiency of NOL-TEC's Dense Phase technology is further enhanced by our exclusive Air Assist technology. Instead of introducing all of the air required to move the material through the convey line at the beginning of the system via the transporter or pressure vessel, air is injected into the conveying line via strategically placed Air Assists. This essentially breaks the system down into several mini-systems, reducing overall resistance and lowering the air supply pressure required to convey the material. This results in increased system efficiency and reliability. NOL-TEC's unique high pressure Air Assist manifold design prevents back-feeding, which may be experienced when utilizing low pressure manifold systems. Key Benefits: Gentle handling of materials Reduced product degradation & segregation Reduced wear of components & system Minimized dusting Routing flexibility Dilute Phase Pneumatic Conveying Dilute Phase pneumatic conveying utilizes a high volume of low pressure (under 15 PSIG) or vacuum air to move powdered and granular bulk materials through an enclosed convey line. The high velocity (3,500 to 9,000 feet per minute) air flow typical of a Dilute Phase system moves materials through the convey line in an airborne state. Dilute Phase pneumatic conveying is extremely cost-effective and is well suited for handling non-abrasive, non-fragile and light-weight materials. Key Benefits: Smaller capital investment Lower installation costs Minimized dusting Routing flexibility | ||
