Product Description

Henan Zhengzhou Mining Machinery Co., Ltd began to manufacture equipments for Mg smelting industry from 1988, and focused on the technology upgrading and utilization. During 2003-2005, the company invented Vertical pre-heater for the calcination of dolomite. This kind of new pre-heater saves fuel by 40% and increases the output by 30%. The exhaust gas is recycled and dust emission can be controlled under 50mg/m3. This kind of new pre-heater takes up more than 85% in the market share. The company has got the patent of energy-saving rotary kiln, vertical pre-heater and vertical cooler.

- Professional Process Design Engineers, Equipment Engineers, Electrical Engineers.
- Leading supplier of magnesium production line, and over 90% market share.  

 

 

 

Production Process

Transported by inclined Belt Conveyor, the fine crushed dolomites will be sent to the Hopper on the top of Preheater and then discharged into Preheater by feeding chute. The high temperature gas from rotary kiln can preheat the dolomites to 800℃. Some of the dolomites can dissociate after preheating. After this process, the dolomites are push out by hydraulic push-rod and get into the Rotary Kiln for calcination with 1100-1250℃ through transfer slide. After calcination, all the materials are discharged into Cooler for cooling to less than 100℃ and then discharge to next process for grinding.

 

We are the leading company of magnesium production lines both at home and abroad,in the year 2011,we have signed an annual output of 100000 tons of magnesium metal project with the world iron and steel giant Korean Pohang iron.

 

 

Magnesium Calcination Process
The company's magnesium production line is very famous, at present,many famous enterprises at home and abroad have chosen to cooperate with our company.


step1: Calcined--The calcined dolomite granular

 

       a.Process introduction: As a result of mining dolomite is too large in volume,So crushing and calcining bulk dolomite, make its become particles.

 

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

 

 

 

step2:Grinding and balling--Raw material production and storage
       a.Process introduction: Calcined dolomite, using a ball mill and other equipment to the grinding ball material, storage after production well.
       b.The main equipment:Electronic batching scale,Bucket elevator, Ball mill, Screw conveyer ,FU chain conveyor,etc.

 

 

 

step3: Reduction treatment -Reduction treatment raw materials
       a.Process introduction: Refine the raw materials, product the qualified products and sales.
       b.List of equipment and processes:Reduction furnace,Wind machine Vacuum pump,Jet pump,etc.

 

step4: Refine--produce a product 
       a.Process introduction:Use of a series of equipment, refine the raw material, create quality products and sales them.
       b.The main equipments:Refining furnace,Electronic moisture device,Pouring pump,Continuous casting machine,etc.

 

Raw material  Magnesite knowledge:

Chemical formula: MgCO3

Chemical composition of MgO (3): 35%-47%

CaO 0.2%-4%

SiO 0.2-8%

Fe2O3 is less than 1%

Al2O3 is less than 1%

 

Heavy burned or light burned magnesium Application:

 

Light burned magnesium ——can be made into many kinds of magnesium salts,used in medicine, rubber, synthetic fiber, paper and other aspects of theraw materials
Heavy burned——Refractory material, used in the manufacture of magnesia brick, magnesite chrome brick, magnesia, powder metallurgy.
