Calcined Bauxite

Calcined Bauxite Calcined Bauxite is produced by sintering high alumina bauxite in rotary round or shaft kilns at high temperatures This process of calcining heating bauxite in kilns removes moisture and gives Calcined Bauxite its high alumina content and refractoriness low iron and grain hardness and toughness Its thermal stability high mechanical strength and resistance to molten

Calcined Bauxite

Calcined bauxite is an extremely hard aggregate and retains the sharp edges produced at the time of crushing this property greatly enhances skid resistance resulting in decreased braking distances Calcined Bauxite is used in combination with thermoplastic resins such as hydrocarbon or rosin ester resins H Rez 1102 or Nuroz RE100 or in two component reactive systems For detailed
