Concasseur à marteaux

Utilisé pour le concassage primaire des matières premières ciment. Les marteaux subissent impact et abrasion ; acier au manganèse et conceptions bimétalliques selon géométrie et zone d’usure.

Les concasseurs à marteaux mono- ou birotor impactent, cisaillent et projettent l’alimentation avec des marteaux articulés. Le remplacement suit le type de rotor, le sens de rotation et l’outillage. Les voies matériaux de cette page restent dans les familles OEM publiées : durcissement local de marteaux monomatériau, coulée composée et batteurs bimétalliques haut chrome.
