  • Minimum Conveying Air Velocity an overview

    For the dilute phase conveying of the cement, a minimum conveying air velocity of 11 m/s is required, but for the potassium sulphate, it is about 14 m/s. At higher solids loading ratios the minimum conveying air velocity for the cement decreases until it is about 3 m/s at a solids loading ratio of about 70.Minimum Air velocity, pick-up speed in pneumatic conveying,With : u pickup = pick-up air velocity in conveying pipe of diameter D at the point of entry of the solids (m/s) Q airin = air volumetric flow rate at the inlet of the solids (m3/s) D in = pipe diameter at the inlet of solids (m).
