Evaluation of Electrostatics in Powder Handling
This course is available as an In-Company course. Please contact us for details.
TBC dependant on number of delegates attending.
Electrostatic charges generated during industrial powder handling processes may give rise to unwanted particle cohesion or adhesion, which in turn results in difficulties such as particle agglomeration, segregation, material build-up on equipment and ignition of explosion, etc. Its impact is felt in terms of lower production yields and increased process downtime, or high risks to safety in manufacture.
The charges are most likely generated by tribo-charging, which arises from particle-particle and particle-wall contacts. Its behaviour is erratic and not easy to predict. Nevertheless it is always desirable to characterize the charging tendency of raw materials so that corrective action can be taken prior to full scale manufacture.
This course discusses the causes and effect of electrostatic charge in bulk solids handling, and the hazards caused to product quality control and risk assessment. Principal charge measurement techniques are reviewed and their use in the prediction and solution of problems discussed.
Split into 3 sessions, the following topics will be dealt with during the course of the day, along with demonstrations in the laboratory as appropriate.
¨ Electrostatic charge phenomenon
¨ Understanding the electrostatic charge
¨ Fundamental theory of electrostatics
¨ Electrostatic charge of particulates
¨ Charge influences on physical properties
¨ Electrostatic hazards
¨ Charge evaluation and measurement techniques
¨ Charge assessment and control
¨ Application of the electrostatic charge
The day ends with a workshop/discussion period relating to your own electrostatic issues.

Plant operators and designers, plant managers and maintenance personnel will all benefit enormously from attending this course, through improving their understanding of the behaviour of powders to learning techniques to overcome the problems encountered.
The course will be of great interest to personnel that are new to materials handling, or require an update on the subject.
The course will be held at the University of Greenwich Medway Short Course Centre, Chatham Maritime, Kent
The course leader is Mike Bradley, Professor of Bulk and Particulate Technologies and Director of the Wolfson Centre. He has worked internationally on design and troubleshooting for bulk solids handling as a commercial consultant and research expert for over twenty years.
Also contributing will be Richard Farnish, Consultant Engineer, who has over ten years' experience in commercial design work related to materials handling; and Dr Rob Berry, a Research Fellow with several years' experience in bulk solids handling technology.
Please note that The Wolfson Centre reserves the right to substitute leaders of equal quality should this be dictated by circumstances beyond their control.
To book your place please complete the online booking form. The fee is payable upon return of the registration form and covers lectures, course notes, lunch and refreshments. All applicants will be acknowledged and confirmed. See here for discounts available and cancellation charges.
Note: It's important to make sure that there is time available to deal the delegates' specific issues. As a result, numbers are strictly limited and we recommend early registration.
This course can be delivered as an In-Company course. These are proving to be a popular option for companies who have a number of personnel who would benefit from education in the subject area, for 3 main reasons:
- COST: It is more economic for us to bring the course to you, than for you to send several staff out to us;
- RELEVANCE: We can tailor the course programme to suit the operations you have in your plant, hence reducing the amount of material which is not directly relevant;
- CONVENIENCE: We can run the course when it suits you, even over several separate days rather than in a block if it is better for you.
