KENT (GB) - This course is available as an In-company short 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:

  1. COST: It is more economic for us to bring the course to you, than for you to send several staff out to us;
  2. 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;
  3. CONVENIENCE: We can run the course when iot suits you, even over several separate days rather than in a block if it is better for you.

If you are interested in discussing your requirements, please contact us.

Course overview

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.

Course content

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. The use of these measurement techniques for prediction and solution of problems is then discussed.

Is this for me?

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.

Venue

The course would normally be held on your premises or using facilities organised by your company.

Course team

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 of bulk solids handling as a commercial consultant and research expert for over twenty years.

Note: the Wolfson Centre reserves the right to substitute leaders of equal quality should this be dictated by circumstances beyond their control.
