Broyeur vertical

Équipement de broyage central. Bandages de galets et blindages de table subissent compression de lit de particules et abrasion. Fonte à haut chrome et composites rechargés sont des options matériaux courantes.

Les broyeurs verticaux à galets compriment et cisaillent un lit de matériau sur une table tournant horizontalement avec plusieurs galets. Le gaz chaud entre par l’anneau de buses autour de la table et emporte les fines vers le classifieur dynamique. Les grossiers retournent à la table ; le tramp et les grossiers difficiles sortent par le système de rejet. Principales pièces d’usure : galets, table, anneau de buses, classifieur et passages gaz poussiéreux.
