Molochite is a hard abrasion resistant alumino silicate produced by the calcination of specially selected kaolins which are critical to ensure the correct mineralogy.
Carefully controlled calcination converts the kaolin into a mixture of Mullite crystals and amorphous silica glass and completely avoids the production of hazardous crystalline silica such as Quartz or Cristobalite. A low iron oxide content is uniformly distributed without the nodular ferruginous slag particles often found in calcined secondary clays. The low, uniform thermal expansion rate of Molochite gives it excellent resistance to thermal shock, while the rough surface texture of the particles gives excellent keying properties for clay or chemical bonding.
Molochite is produced using selected kaolin components which are low in iron and alkalis and high in alumina.
There are three distinct stages of processing:
Preparation of kaolin to produce the calciner feed
Calcination
Crushing, screening and ball milling
