Study of aeraulic phenomena on the appearance of inter-batch transfer and dust clouds in industrial animal feed production circuits.


European regulations require manufacturers to control carry-over and dust explosions. The work therefore concerns identification and study of the mechanisms causing the formation and displacement of dust clouds in animal feed facilities to enable their management on industrial site, and in particular bucket elevators.

The trials were carried out in pilot station to be able to realize a vast plan of experiment (32 tests) with confirmations of the phenomena observed during tests on industrial sites. The results clearly showed the impact of bucket elevators in the generation od dust deposits.
