Magnesium Calcination Process
step1: Calcining

       a. Process introduction: Selecting proper dolomite (size from 10-50mm),crushing and screening after it is carried to the factory, then feed the dolomite (>20mm) to the calcination system(including preheater,rotary kiln and cooler), after calcination and cooling, then the calcined dolomite will be conveyed to the hopper.

       b. Main Equipments: Jaw Crusher, Conveyor, Vibrating screen, Vertical preheater, Rotary kiln, Vertical cooler, etc.

step2:Grinding and balling
       a.Process introduction: Using jaw crusher and ferrosilicon crusher to crush and grind ferrosilicon to the size of less than 20mm, then grinding these three kinds of minerals(calcined dolomite,ferrosilicon and fluorite), after grinding, convey them to the briquetter.
       b.Main equipment: Electronic batching scale, Bucket elevator, Ball mill, Screw conveyer ,FU chain conveyor, etc.

step3:Reduction reaction and Refining 
       a.Process introduction: To refine the raw materials, and produce qualified products.
       b.Main equipment: Reduction furnace, Refining furnace, Electronic moisture device, Wind machine, Vacuum pump, Electronic moisture device, Jet pump, Continuous casting machine, etc.
