Abstract

The invention discloses a high-temperature magnesium oxide calcining device and a calcining method thereof, and belongs to the technical field of magnesium oxide calcining. The device comprises a feeder, an air flow dryer, a first-stage cyclone pre-heater, a second-stage cyclone pre-heater, a third-stage cyclone pre-heater, a dust remover, an induced draft fan, a calcining furnace, an automatic fuel gas burner, a heat preservation conditioning furnace, a discharging device, a material collector and a cooling system. According to the invention, magnesite powder or light calcined magnesia powderis used as a raw material; a three-stage cyclone pre-heater set is adopted for completing preheating treatment of materials, and high-temperature calcination and heat preservation conditioning are conducted, wherein tail gas is calcined to achieve material drying and preheating process treatment, the process is a dynamic material flow-carrying mass transfer and heat transfer process, high-qualitymagnesium oxide is produced while heat energy is effectively utilized, and cost is saved; and the production of magnesium oxide products with different quality indexes, which are suitable for the field of building materials, can be realized.

Description

technical field [0001] The invention belongs to the technical field of magnesia calcination, and in particular relates to a device and a calcination method for producing magnesia by high-temperature calcination with magnesite powder or light-burned magnesium powder as raw materials. Background technique [0002] Magnesium-based cement produced with magnesium oxide as the base material is widely used in building materials, decorative materials, and packaging materials. Because of different application fields, each field has different requirements for the physical and chemical properties of the base material magnesium oxide. Using magnesium oxide-rich magnesite powder or light-burned magnesium oxide powder as raw materials, by adjusting the temperature of the high-temperature calcination process and the holding time of the quenched and tempered material, different quality categories of magnesium oxide can be produced to achieve applications in different fields Indicator requir...
