Abstract

Dans une méthode de traitement dun matériau paysager particulaire, le matériau est introduit dans une chambre de mélange et un mélange additif comprenant un additif fonctionnel et un support est fourni à des becs de pulvérisation au sein de la chambre de mélange. Au moins un bec de pulvérisation fonctionne dans le but de diriger une pulvérisation atomisée dans la chambre de mélange. Le matériau est malaxé dans la chambre de mélange durant la direction de la pulvérisation atomisée dans la chambre de mélange ou à la suite de la direction de la pulvérisation atomisée dans la chambre de mélange. Par la suite, le matériau et le mélange additif sont acheminés vers une sortie de la chambre de mélange. Durant ces étapes, un débit volumétrique du matériau paysager particulaire à travers la chambre de mélange est établi de manière intermittente. Le débit volumétrique établi est comparé de manière intermittente à un débit cible prédéterminé du matériau paysager particulaire. Le débit volumétrique du matériau paysager particulaire à travers la chambre de mélange est ajusté, en fonction de cette comparaison.
