Parameters affecting Power Consumption in Pneumatic Conveying of Fine Particles

By N. Behera, V.K. Agarwal, M.G. Jones, K.C. Williams – Pneumatic conveying of certain bulk materials is widely used in industries due to certain advantages over other modes of conveying. As compared to dilute phase, dense phase conveying is a preferred method of conveying due to its low power consumption, low erosive wear and low attrition of particles. Fly ash and alumina being high aeration capable due to their fine particle size tend to be conveyed in fluidised dense mode at low velocities. In this paper, details of pneumatic conveying tests are presented which are carried out using fly ash and alumina as conveying material at different solids loading ratios for dense mode as well as dilute mode of flow.

The Proper Flow Rate – Material Feed Rate Control for Pneumatic Conveying Systems

By D. Mills, V. Agarwal The material feeding device is particularly critical to the successful operation of any pneumatic conveying system. Many of the feeders available have no moving parts and it is not always obvious how material flow rate can be reliably achieved.

How to divide a Pneumatic Conveying Stream – Splitter for continuous Distribution of Bulk Solid Material during Pneumatic Conveyance

By K. Schneider Worldwide, a high number of so-called splitters as elements of pneumatic conveying lines are in operation, in order to continuously distribute the conveyed bulk material to several receiving stations. The present article provides an overview over the possible applications and typical configurations of splitters, with their advantages and disadvantages. Furthermore various selection criteria for usage of splitters are introduced and discussed.

Kason: Twin In-Line Pneumatic Centrifugal Sifter cantilevers for quick Cleaning

Stoke-on-Trent, United Kingdom A new Model Twin XOB-PS-SS Pneumati-Sifter™ Ultra High Capacity dual centrifugal sifter from Kason de-agglomerates and screens bulk materials in-line with dilute-phase pneumatic conveying systems at ultra-high rates. Rated up to 1 barg positive pressure and 356 mm vacuum, it delivers the capacity of two independent high-output sifters, but in less floor space.

Breakage of Powders in Lean-Phase Pneumatic Conveying: The Influence of Material Type

By B.A. Kotzur, R.J. Berry, M.S.A. Bradley, and R.J. Farnish – Lean-phase pneumatic conveying is utilised across a wide range of industrial processes. This conveying method offers a number of advantages such as process hygiene and routing flexibility, however, due to high impact velocities in the pipeline, particle attrition remains a considerable issue. This work looks at how different material types respond to equivalent impact conditions, namely amorphous (Carbolux) and crystalline (cooking salt) morphologies, and translates this to expected behaviour during conveying. A bespoke bench-scale centrifugal attrition tester was used to test an individual particle size fraction of each material across two impact angles and five impact velocities. It was found that the percentage mass retained in the size fraction reduced linearly with velocity for the amorphous material, and polymerically for the crystalline material.

Entirely Dust-free: Hybridysing Pneumatic and Mechanical Conveying for Bulk Material Handling

For the enlosed conveying of powdery or granular products may happen in pneumatic as well as in mechanical systems. An interesting alternative are aero-mechanical systems, which allow very gentle conveying even of friable products.

HammerTek: Smart Elbow Deflection Elbow prevents Breakage

Bethlehem (PA), United States When using conventional sweep elbows in pneumatic conveying systems, friable material impacting the elbow wall at high speed causes breakage and fines. With the HammerTek® SMART ELBOW® Deflection Elbow, deflection of friable material around the bend prevents impact, breakage and fines. Continue reading HammerTek: Smart Elbow Deflection Elbow prevents Breakage
