How does the angle of the trommel drum affect material separation
1 answer
Lorsqu'un tambour est trop incliné, la gravité accélère le flux des matériaux, ce qui peut réduire le temps de résidence et limiter la séparation, surtout pour les particules de petite taille qui nécessitent plus de temps pour passer à travers les mailles. En revanche, un angle trop faible peut ralentir excessivement le flux, entraînant une accumulation et potentiellement un colmatage, ce qui diminue l'efficacité du processus.
L'angle doit donc être ajusté en fonction de la nature des matériaux traités, de leur granulométrie et de la capacité souhaitée. Par exemple, pour des matériaux légers ou de petite taille, un angle moindre peut être plus approprié. Des paramètres comme la vitesse de rotation du tambour et la configuration des grilles doivent également être optimisés conjointement avec l'angle pour maximiser le rendement et la qualité de la séparation.
