• Pickup Velocity for Pneumatic Conveying

The velocity of the air necessary to convey a material in suspension flow depends mainly on the particle properties of size, shape, and density. For fine powders the minimum conveying air velocity required will be in the region of 2000–2400 ft/min; 2000–2200 ft/min for cement; and 2200–2400 ft/min for fly ash

• Minimum Conveying Air Velocity - an overview

The relationship between the minimum conveying air velocity and the solids loading ratio at which the materials can be conveyed is presented in Fig. 16.3.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

1. Definition of saltation velocity. In a pneumatic conveying system, the saltation velocity is the air conveying velocity below which the solids being conveyed starts to settle at the bottom of horizontal pipes.In order to be able to convey in dilute phase a bulk solids such as a powder or granulates, the minimum air conveying velocity in all part of the line must be HIGHER than the saltation
