Occurs when the material is conveyed at a velocity above the saltation velocity (minimum conveying/suspension velocity) of the material. In this type of system the material is “suspended” in the conveying air stream and typically requires pick-up conveying air velocities of 3,200 to 7,000 feet per minute. Dilute phase systems typically operate at positive pressures of 5-12 PSIG or negative pressures of 4-12” Hg with solids to air ratios (pounds of product per pound of air) of less than 12:1. This type of conveying system is typically utilized to convey materials that are not susceptible to degradation or are not abrasive in nature. CONTRAN™ Continous Dense Phase Transfer This type of conveying system is typically utilized to convey materials that are susceptible to “crushing” or “impact” degradation and also can be utilized when material segregation is of a concern. Continuous dense phase systems typically operate at positive pressures of 8-40 PSIG or negative pressures up to 29” Hg with solids to air ratios (pounds of product per pound of air) of less than 25:1. This type of conveying system is typically utilized to convey materials that are susceptible to “sliding” or “rolling” degradation or are abrasive in nature and also can be utilized when material segregation is of a concern. Pressure pot dense phase systems typically operate at positive pressures of 25-50 PSIG or negative pressures up to 29” Hg with solids to air ratios (pounds of product per pound of air) of greater than 30:1. Automation will make your process system the most productive it can be. A control center must meet your requirements to be effective, and because Horizon Systems’ control panels are custom built from start to finish, you get exactly what you need, whether it is relay logic, solid state circuitry, or a programmable logic controller. Our panels, though custom built, use standard, readily available components, designed for future expansion or replacement.
