High pressure grinding roller equipment teeth: through the technological method which the cemented carbide column nail studded on the roller to form a roller surface wear layer, which promote the technological innovation of the roller mill, at the same time, the adaptive capacity of roller mill is higher, expanding the application fields, the using life is longer, the efficiency is higher. Recommend grade no YG11C, YG15, YG15C, YG18, YG20 Usage: High pressure grinding roller, iron ore, cement crushing. Grades above are exclusive grade we developed for rolling machine. Good wear resistance and high strength are suitable for metal smashing with high working efficiency. Tungsten carbide studs is widely used in crushing non-ferrous metal ore such as bauxite, iron ore, gold ore, etc. as well as other materials such as cement raw material, clinker, furnace slag and limestone, etc. Size : OD 10XH17, OD16x H50,18x45,20x40,16x40,20x35mm, etc. Customized carbide studs as per drawing or samples are also available
