Abstract
Mining uses only a fraction of the amount of land that the agricultural industries use, and it’s part of the renewable solution as well; however, mining consumes 2 to 3% of the world's electricity for comminution alone, demonstrating one of the many compelling reasons why comminution must be more energy efficient. Material science applied in crusher and grinder wear parts manufacturing can reduce energy consumption in the crushing and grinding operations themselves.
Wear parts (for example, bowl and mantels for pebble crushers, jaw plates for jaw crushers, mantels and concaves for gyratory crushers, and/or rollers for high-pressure grinding rolls) can be manufactured solely using new alloys, or through a combination of new alloys and ceramic materials. Wear parts derived from material science-based inventions can preserve original as casted dimensions and angles during the entire wear mechanism. A crusher with a dimensionally consistent crushing chamber will increase productivity and reduce energy consumption by allowing a better flow of material and optimal crushing dynamics.
This presentation describes the advantages of using non-traditional alloys (or ceramic and alloy combinations) to produce wear parts used in comminution through literature review and case studies.
