INTRODUCTION

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.

Pidgeon process is applied in the company’s Mg smelting technology. This kind of process is advanced and reliable technology.

Qualified dolomite is transported into the rotary kiln for calcination; Calcined dolomite is mixed with fluorite and ferrosilicon and then pressed into briquette. The briquette is put into retorts where there is vacuum, and then deoxidized into crystallized Magnesium, which is called crude Mg. Crude Mg is smelted and refined to get pure Mg. The complete production line is divided into several systems including raw material storage, dolomite calcination, grinding&briquetting, reduction and refining.

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 Products: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.



FEATURES

1. Saving energy

The refractory lining of the rotary kiln consists of the outer insulation made of light refractory brick and inner compound refractory bricks. Such kind of lining will reduce the heat emission on the shell surface of the rotary kiln as much as possible. The pre-heater at the end of the rotary kiln will recycle the heat to preheat the material and save fuel by 40% and increase the output by 30%.

2. Low consumption

The vertical cooler at the discharge end of rotary kiln recycles the heat of the calcined dolomite which is discharged from the rotary kiln, and will preheat the secondary air up to 600. The vertical cooler is integrated with kiln hood to prevent the waste caused by heat emission from the discharged calcined dolomite

3. Environmental protection

Two phases of dust collection including cyclone filter and bag filter, will control the dust emission below the limitation of the national standard.

4. High degree of automation

PLC control system improve the job efficiency.
