Our Advantage
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.
Production Process 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.
Step 4: 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.
