Introduction to magnesite calcination:
The traditional method of magnesite calcination is carried out in the shaft kiln, which is also conducive to the rotary kiln. Both shaft kiln and rotary kiln calcine lump ore, which has the characteristics of long calcination time, uneven calcination, affecting product activity, environmental pollution and waste of resources. Using dynamic calciner can solve the problems existing in calcination at present.
Product introduction: dynamic calciner (suspension calciner) is a furnace type for calcining crushed magnesite powder (or magnesite filter cake after flotation) with hot air. It is mainly composed of preheating dryer, heat exchanger, calcination and decomposition furnace, trap, heat source, etc. After entering the furnace, the material can be decomposed quickly in a few seconds. Because the powder material is calcined, the calcined material is uniform, there is no raw burning and overburning, and the calcination temperature can be accurately controlled. Working principle: powdered materials or cake magnesite after flotation magnesite slime are sent to the dryer or preheating by the feeder. The waste heat air produced by calcining and decomposing magnesite in the calciner is used as the above drying heat source. The dried magnesite is sent to the calciner for calcination, and the decomposed magnesium oxide (light burned magnesium) is discharged from the discharge port.
Performance characteristics: 1 The calcined materials are uniform and sufficient to produce active magnesium oxide. 2. The equipment system is free of pollution and meets the requirements of environmental protection. 3. Energy consumption can be saved by 20 ~ 30% compared with shaft kiln 4 The equipment operates continuously and the quality is stable. 5. Convenient operation and high degree of automation. 5. Save heat energy and use the heat of calciner tail gas to preheat raw materials. |
