BiMetalic Grinding Components
Crushing and grinding of coal and ores has traditionally been handled using components cast from wear grade irons and exotic steels and alloys, such as White Irons, NiHard, HiChrome, etc.
These irons and alloys , while being wear resistant, are also quite brittle and some are unable to withstand excessive rapid temperature variations, or significant impact, etc.
Austral Technologies recognized a requirement for components that are able to withstand these extreme conditions, while at the same time, provide superior wear resistance.
A patented BiMetallic Grinding Component was developed in the form of a specific alloy steel base material and a wear resistant hardface overlay. This provides a life increase over the original NiHard white iron component, while providing better impact and superior ability to withstand rapid extream temperature fluctuations
Some of Austral's Chromium Carbide overlays have reached thicknesses of upto 160mm; these being applied to NiHard IV High Pressure Rolls Crusher Segments
