Product Description

Magnesium Oxide Calciner

Introduction:

     Magnesium carbonate decomposes to magnesium oxide through chemical methods. The

currently used calciners are either shaft kilns or rotary kilns. However, the shaft kiln wastes

energy and causes contamination, resulting in unstable quality of the corresponding products. In

contrast, utilizing a dynamic calciner allows to obtaining significantly better products compared

to those obtained from the aforementioned traditional calciners.

     Our dynamic drying and calcination combo is primarily used for magnesium carbonate. The

magnesium carbonate filter cake, after dehydration, is dried using the heat from calcination tail

gases. Subsequently, the dehydrated powders are introduced into a calcination furnace where

they decompose into magnesium oxide. Consequently, the calcination temperature ranges from

800 to 900 degrees Celsius, with a duration of 3 to 4 seconds.

Working Pinciple:
 
     To convey the tail gas from the dynamic calciner's calcination process into the Sid calciner, a

feeder is used to transport magnesium carbonate filter cakes (with a moisture content of 70% to

80%) to the dryer. After being dispersed and dehydrated, they form powders and enter the

calciner. Simultaneously, hot air heated by coal, natural gas or coal gas combustion enters the

calciner. Heat transfer occurs between this hot air and magnesium carbonate powders which

quickly decompose into magnesium oxide within seconds in an atmosphere of 800 to 900

degrees Celsius. These magnesium oxide powders then pass through a collector before reaching

the silo.

Technical specifications:

     A single unit can produce an output of 1, 2, 3, or 5 tons per year.

Technical process:

Application cases:

     There are around 30 enterprises using the magnesium oxide calciners.
