Caking and Lump Formation in Powders and Bulk Solids

Rotary valves are widely used to feed pneumatic conveying pipelines, and for feed metering, explosion isolation, atmospheric isolation etc. However there are a multitude of combinations of different feature options available covering choice of materials of construction, rotor type, drive type, venting arrangements, bearing pattern, seal choice, clearances, cleaning features etc. Faced with this bewildering choice, how does an engineer decide what to specify? This course will help understand the reasons for the different options and how to choose them. Topics will include: * Application areas for rotary valves, and their different demands (feeding, explosion protection, isolation etc) * Basics of rotary valve performance – air leakage, feed rate etc * Materials of construction linked to issues of wear and build-up * Seals and bearings, options, functions and selection * Special consideration for explosion isolation * ATEX requirements and responsibilities * Features for cleaning and preventing contamination * Venting – needs, options and ensuring success * Review of practical application issues The course is aimed at engineers, system designers, maintenance personnel who have responsibility for sourcing, specifying and keeping operational rotary valves in all industries. Course fees are £580 per person

Workshop Week sessions give delegates an insight into how and why various powder handling techniques are used, and how these can enhance bulk materials handling services offered to Industry. Delivered over 4 days, different applications will be presented each day: - Understanding Powder Flow - Characterisation Techniques - Pneumatic Conveying - Dust Contamination and Filtration Delegates may stay for as many sessions as required.

Overview: This course looks at the causes and effects of de-blending (segregation) of bulk particulates Subjects covered: * Identification of the most commonly encountered segregation mechanisms * Examples of how segregation has occurred in plant * Techniques that can be applied in plant design to minimise these effects Different types of segregation will also be identified; air-induced, rolling, surface effect, percolation. Course fees: £525 per person Early Bird Registration £450 until 31 December 2026 [**NOTE**Auf Deutsch**Der Kurs wird online auf Englisch abgehalten.

Overview: Delegates will look at the setting up and commissioning of pneumatic conveying systems. This course is a ’Hands on’ fully practical session using the pneumatic conveying lines and rotary valves in the on-site laboratories in Chatham. Subjects covered: * The practical challenge of starting up systems on site and making sure they work as the designer intended; * Understand the key signals to look out for that tell you how the system is operating; * Avoiding pitfalls that can lead to slow start up, blockages etc; * How to know when the system is operating as intended; * Ensuring the system is optimised around the users priority requirements eg. minimum energy usage/ particle blockage / system wear; * It also covers lean and dense phase, rotary valves, blow tanks and various air supply types Course fee: £915 per delegate Venue: Chatham, Kent Contact: Caroline Chapman

Die Prozesstechnik hat sich in den letzten Jahrzehnten enorm weiterentwickelt. Doch Fließprobleme bestehen weiterhin. Dieser Artikel erörtert einige der häufigsten Ursachen. Von R.J. Farnish Die Förderung und Lagerung von Schüttgütern innerhalb von Prozessen ist seit der industriellen Revolution im 18. Jahrhundert eine grundlegende Aufgabe für viele Anlagen. Die Prozesstechnologien haben sich in der Zwischenzeit bis heute in ihrer Komplexität und Effizienz enorm weiterentwickelt. Wäre es möglich, einen Ingenieur aus den Anfängen der Industrialisierung in die heutige Zeit zu versetzen, würde er angesichts der enormen Vielfalt an Prozessanlagen, die auf spezifische Anforderungen und Endprodukte zugeschnitten sind, seinen Augen kaum trauen. Was er jedoch mit Sicherheit wiedererkennen würde, sind schlecht funktionierende Silos, Bunker und Trichter, die nicht selten unsanft von den Anlagenbedienern bearbeitet werden. Dieser Artikel behandelt einige der häufigsten Ursachen für Verarbeitungs- und Fließprobleme, die über die Jahrzehnte hinweg bestehen geblieben sind. Grundlagen Die Austragsprobleme bei der Handhabung von Schüttgütern mit weniger…
