Rotary kiln/Rotary kiln price/Ore rotary kiln

Rotary kiln/Rotary kiln price/Ore rotary kiln , namely clinker rotary kiln, belongs to building material equipment and it can be divided into cement kiln, metallurgy chemical kiln and lime kiln according to different materials.

Cement kiln is used for making of cement clinker and there are dry and wet methods to make cement.

Metallurgy chemical kiln is used for magnetic roasting of iron ore and oxidizing roasting of chrome and nickel in the steel factory, baking high-alumina mine in the refractory material factory, baking chamotte, alumina in the aluminium factory, baking chrome ore and chrome powder in the chemical plant.

Lime kiln is used for baking active lime and dolomite in the steel factory and ferroalloy factory.

Two Main Types of Rotary Kilns

Cement kiln is used for making of cement clinker and there are dry and wet methods to make cement. Metallurgy chemical kiln is used for magnetic roasting of iron ore and oxidizing roasting of chrome and nickel in the steel factory; baking high-alumina mine in the refractory material factory; baking chamotte and alumina in the aluminium factory and baking chrome ore and chrome powder in the chemical plant.

Lime kiln is used for baking active lime and dolomite in the steel factory and ferroalloy factory.

Structural Featuers of Rotary Kiln
1. Supporting device apply rolling bearing ( few with sliding bearing) to simple the bearing structure to slow down the kiln power consumption and it also improve the maintenance and inspection conditions.

2. Catch wheel: including two kinds mechanical wheel and hydraulic pressure

3. Gears: single or double. Control the rotating speed by buncher, DE machine and frequency variable motor. Be reliable, energy-saving, and efficient.

4. Cylinder type bolster: lower bolster has three types: fixed, zoom and floating. The structure is simple, replacement is convenient and won’t hurt cylinder.

5. Sealing equipment: there are many kinds for choice according to kiln models, including air cylinder edge sealing, spring edge sealing, and graphite block sealing and combination for above. The feather is adaptive for cylinder rotating and swing. And sealing effect is very good.

6. Kiln head hood: including stationary type and flexible type.

7. Transmission device apply speed adjustable motor with big speed adjustable range, stable operation, easy to maintenance advantages. Our Rotary Kiln has slow disk kiln structure, which is composed by Diesel engine, gearbox, etc. It could continue to operate when electric stops, its operation is very flexible and convenient and easy for the kiln maintenance and inspection.

Rotary kiln is a pyroprocessing device used to raise materials to a high temperature (calcination) in a continuous process. Materials produced using rotary kilns include:

• Cement
• Lime
• Refractories
• Metakaolin
• Titanium dioxide
• Alumina
• Vermiculite
• Iron ore pellets

Different kiln type has different preheating, calcining, cooling and discharging method. But a few technology principles are the same : the raw materials of high quality, good quality of lime; high calorific value of fuel, the quantity consumed less; and calcining time proportional to the particle size of limestone; quicklime activity inversely proportional to calcination time and calcination temperature.

The Rotary Kiln is thermal processing equipment for heating the bulk or slurry material and is used in various industries such as non-ferrous metallurgy, ferrous metallurgy, refractories, cement, environmental protection,chemical and paper industries.

Rotary kiln/Rotary kiln price/Ore rotary kiln structure features:
The kiln is composed of the cylindrical shell ,kiln liner, cylinder accessories , sealing device at kiln outlet ,transmission device ,supporting device with thrust roller ,burner ,sealing device at kiln inlet , feeding device etc. The kiln shell is designed to keep some inclination to level .It is supported by the roller supporting device and equipped with thrust roller device to control the up and down moving of the shell .The driving system is equipped not only the main driving gear unit but also the auxiliary driving used to keep the shell rotating even when the main power is broken so as to prevent the shell from any bending and distortion .As the kiln head and tail are sealed by advanced technology ,the sealing of the kiln is fairly reliable.

Rotary kiln/Rotary kiln price/Ore rotary kiln working principle:
Materials enter from the kiln outlet (the high end of the cylinder) into the kiln for calcination. Due to the tilt cylinder and slowly rotating, materials are not only rolling along the circumferential direction but also moving along the axial direction (from high to low), continuing to complete the process. Finally, the clinker enter into the cooler through kiln hood for cooling. Fuel is sprayed into the kiln through the kiln head, and exhaust gas produced by combustion exchanges with material, and then discharges from kiln outlet.
