Product introduction of magnesite rotary kiln

Magnesite is the dominant mineral resources in China and is a carbonate mineral of magnesium, often replacing magnesium with iron and manganese, but the iron content of natural magnesite is generally not high, and it is the main raw material for manufacturing alkaline magnesite refractory materials and extracting metal magnesium. Magnesite is mainly used for calcination of light-fired magnesite, sintered magnesite, fused magnesite and other refractory materials. At present, light-fired magnesite is mainly used in rotary kiln equipment.

Outstanding advantage

1, good product quality, high output;

2, stable production and operation, high safety;

3, rotary kiln structure is simple, strong controllability, conducive to operation and maintenance;

4, with high utilization of raw materials, full calcination, uniform quality, good quality, large capacity.

Working principle

The magnesite is fed into the kiln through the kiln tail (high end) chute. Due to the tilt and slow rotation of the cylinder, the magnesite rolls along the circumference and moves axially from the kiln tail (high end) to the kiln head (low end). Fuel from the kiln head through the burner into the kiln for combustion, heat by radiation, convection, conduction and other ways to the magnesite, magnesite in the kiln after preheating, decomposition, sintering and other processes, calcined into calcined white, and then discharged from the kiln head device.
