Alumina is the raw material for the production of aluminum metal. The processing of alumina requires high temperature and pressure, and the alumina rotary kiln is a key part of this process. The alumina rotary kiln is designed to rotate at a constant speed at high temperature. The kiln barrel is lined with high-temperature refractory bricks, and a burner is installed in the kiln to generate heat. The burner can use coal, gas or oil as fuel. Jiutian Alumina Rotary Kiln is a diameter-type rotary kiln developed by Jiutian technicians after years of research based on the existing industrial alumina production practice. It has the characteristics of energy saving, easy operation, and stable operation.
Suitable for calcining alumina, bauxite and aluminum hydroxide
During the operation of the alumina rotary kiln, raw material powder is fed into the kiln cylinder from the feed pipe at the high end of the kiln tail cylinder. Due to the inclination and slow rotation of the kiln cylinder, the material undergoes a compound motion of rolling along the circumferential direction and moving from the high temperature to the low end along the axial direction. The raw material is discharged from the bottom of the kiln cylinder through decomposition, burning and other process in the kiln and enters the cooler. The fuel is sprayed into the kiln head and burned in the kiln. The heat generated heats the raw material and calcines it into clinker. The hot air formed in the process of exchanging with the material enters the kiln system from the kiln feed end and is finally discharged into the atmosphere through the chimney.
