Abstract (en)

[origin: EP0976442A2] Tungsten carbide is used as a wear resistant material, which is applied to the blade by welding. The rotor arm (24) projects radially from a rotor shaft (23) and holds a carrier (36) on which the mixer blade (38) is fitted. The carrier and blade are angled relative to the rotor arm axis. All items are joined demountably through bolts (34, 42, 44) for adjustment and replacement. The rotor arm is also protected by a tungsten carbide coated sleeve (40). A welded coating is preferred to a solid tungsten carbide part to retain the flexibility of the base metal, necessary to cope with shock loading.
