Long lasting impact and crushing hammers
Limits of wear resistance by using mono-metallic alloys have been reached.
Wear becomes significant cost factor not only due to repurchasing and changing wear parts but also due to shutdown times. Next step in manufacturing wear resistant parts is to manufacture bimetallic elements that can withstand high impact loads and have abrasion resistance of highly alloyed white chromium iron.
Patented technology, provides risk free operation with highly wear and impact resistant chromium cast iron is used in impact parts of hammers and combined with Cr-Mo alloyed tempered steel. This technology allows usage of hammers in hammer mill plant in weight range up to 170kg simultaneously combining abrasion resistance of chromium white iron with hardness up to 64 HRc and toughness of 28 - 32 HRc alloyed tempered Cr-Mo steel.
Bimetallic hammers are designed to extend the life of each hammer application, resulting in reduced overall costs, longer MTBF (Mean Time Between Failure) and reduced overall downtime. New technologies permit the production of bimetallic wear castings independent from the materials used and the geometry or weight of the components.
Two different molten metals are poured into specially designed mould. Using different ferro-based materials for the shaft and the wear parts gives the components a highly specialized portfolio of properties.
A significant improvement in life span of parts which are subjected to high dynamical stresses and at the same time by high abrasive wear is possible This enables significant reduction of costs due to repurchasing and changing of wear parts but also due to shutdown times.
