Pneumatic Conveying, Performance and Calculations!

2008-7-7  All the conditions at the intake of a pneumatic conveying system are known. Therefore the intake is chosen as the start of the calculation. In vacuum- and pressure pneumatic conveying calculations, the used product properties are identical. The only difference is the mass flow, generated by a compressor in vacuum mode or pressure mode.

Introduction to Pneumatic Conveying of Solids

Pneumatic conveying is the movement of solids through pipe using gas (usually air) as the motive force. It differs from hydraulic or slurry conveying in that the gas expands continuously along the pipe length. The flow regime in the pipe depends greatly on the ratio of solids to gas and the particle characteristics.

2021-5-24  Pneumatic conveying systems are used to transfer bulk solids materials (powder, granule...) in pipes by using a gas, most of the time air, as the transport medium. Although simple in appearance, many design and operational parameters must be well mastered to implement a successful pneumatic conveying system.
