Dolomite Introduction of Cement Lime Refractories, Metakaokin Rotary Kiln:
Dolomite is an anhydrous carbonate mineral composed of calcium magnesium carbonate, ideally CaMg(CO3)2. Dolomite is used as an ornamental stone, a concrete aggregate, and a source of magnesium oxide, as well as in the Pidgeon process for the production of magnesium.
Magnesium oxide rotary kiln working site:
Magnesium oxide rotary kiln is known as magnesium metal rotary kiln.
Application: chemical products - magnesium sulfate, magnesium sulfate heptahydrate
In refractory aspect it is the main raw material for production of the steelmaking magnesium ball bottom material
In the building aspect,it is widely used in the production of container, fire board, arts and crafts, vegetable greenhouses, wall insulation boards, activity boards, asbestos and other.
It can increase wear resistance, good adsorption, a lower melting point and can change metal lattice structure (fine),so it is used in paint painting refractory bricks, magnetism material, ceramic, rubber tires, and so on.
Magnesium oxide rotary kiln working process:
Step1: Dolomite crushing process
The main equipment includes: dolomite jaw crusher, dolomite impact crusher, dolomite cone crusher etc...
Step 2: Dolomite calcination process
The main equipment includes: vertical preheater, dolomite rotary kiln, vertical cooler.
Step3: Calcined dolomite Grinding and balling
after the Calcined dolomite, using a ball mill and other equipment to the grinding ball material, storage after production well.
The main equipment includes: Electronic batching scale,Bucket elevator, Ball mill, Screw conveyer ,FU chain conveyor,etc.
step4: Reduction treatment -Reduction treatment raw materials
to Refine the raw materials, and product the qualified products and sales.
The main equipment includes: Reduction furnace,Wind machine Vacuum pump,Jet pump,etc.
step4: Refine-to produce final Mg metal
Use of a series of equipment, refine the raw material, create quality products and sales them.
The main equipment includes Refining furnace, Electronic moisture device, Pouring pump, Continuous casting machine etc.
Structure of Magnesium oxide rotary kiln:
Magnesium oxide rotary kiln is made of cylinder, gear, prop, gear wheel bearing device, kiln, kiln sealing parts, kiln hood and combustion devices. Cylinder of magnesium oxide rotary kiln is the heated rotary parts and is made of quality sedation steel plate welded. Due to the particularity of the calcination process, our furnace adopt Diameter changes type kiln body, Through the wheel with bearing block in 2 to 4 on the sliding or rolling bearings devices, and in one block or block support device set a mechanical or hydraulic gear wheel, magnesium oxide rotary kiln control the axial movement of the cylinder; The transmission device of magnesium oxide rotary kiln speed rotary according the requirements through the ring gear in the cylinder central cylinder rotation; Due to the requirements of installation and maintenance,large magnesium oxide rotary kiln set auxiliary transmission device ,which make kiln body speed in a low rotary;In order to prevent cold air into and gas dust overflow the tube,we set reliable preheater and kiln head sealing device in the feeding end and discharge end for the magnesium oxide rotary kiln's cylinder.
