Graphic element Confronting the problem of electrostatic charge in powder processing
     
 
Electrostatic charging of powder can lead to a range of industrial problems. New information improves handling efficiency, allowing the location and resolution of electrostatic problems.
 

Electrostatic charging of powder causes it to be attracted to, or repelled from, nearby surfaces or surrounding particles. This can lead to variations in bulk density, choking of machines, and a range of other industrial problems.

This project aimed to improve the economic efficiency of pneumatic conveying, milling and mixing in a test process plant - a Spanish cement factory - by reducing electrostatic powder adhesion. New powder categorisation methods were developed and test rigs set up to model processing machines. Laboratory tests were then repeated on an industrial scale. The results will enable the European cement, sulphur, pharmaceutical, food, nuclear, paper, textile and other industries to locate the causes of electrostatic charge problems, to quantify them and to deal with them appropriately.

The prime partner, Chilworth, as well as the other non-manufacturing partners, are now providing consulting to improve a range of industrial situations. Some of the participants have gone on to work on other EC projects. Partners say Brite Euram participation meant enhanced recognition and that without EC funding the project would not have taken place.
