Calcined Bauxite Kiln

Specifications

New Prefabricated Kiln

For quick and easy installation on flat concrete floor, very compact with latest prefab kiln technology incorporated.

The prefabricated kiln is a small or medium size kiln which is fabricated in our factory and delivered in separate modules to be joined at the site.

To reduce the investment and operation cost, we built the prefabricated kiln with suspended kiln wall, which is supported by steel structure. Thus the wheel of the kiln car will be exposed in the atmosphere, the working tempeature of wheel is designed around 80°C and the requirement for lubrication will be much less.

The Unique Waste Heat Utilization system provides less power requirement and less fuel consumption.

The main parameters of one new concept kiln with daily output of 100T to be executed in 2010 are given as below for reference only: 

• The designed sintering temperature: 1,670°C;
• The designed limiting temperature: 1,800°C;
• Output: 100T/day;
• Total length: 40m (net width: 4.6m);
• Product:  Calcined Bauxite, Synthetic Mullite, Homogenized Materials (Synthetic Mullite, Synthetic Corundum, and so on);
• Fuel:  Coal gas
• Fuel consumption:  30,000~33,000Nm³ of coal gas per day (its heat calorie value is about 2,700Kcal/Nm³), which is equivalent to 900Kcal per kg of calcined bauxite (Al₂O₃: 80~93%) at sintering working temperature between 1,650~1,670°C
• Power consumption: 35~45 KWH
• Firing period: 120 hours
• Long firing time generating more corundum phase and few glass phase
