Abstract

L'invention concerne une trémie destinée à être chargée au moyen de bennes sans qu'il se produise de dégagement de poussières vers l'extérieur. Elle comporte, à sa partie supérieure, une grille d'éclatement munie d'un réseau de tôles de déversement et de bavettes d'étanchéité souples formant clapets anti-retour. Ces trémies trouvent de nombreuses applications dans diverses industries et en particulier dans les industries alimentaires et agricoles.
