Rotary Kiln

Rotary kiln, which can also be called circumgyrate kiln or revolving kiln, is a drum with a certain inclination of 3~3.5%. Relying on the rotation of the cylinder, the materials inside the revolving kiln will mix, contact and have reactions. 

The kiln head will inject coal which will burn to produce a lot of heat which will be transmitted to the materials in the methods of the radiation of the flame, the convection of the hot air and the kiln burnt brick conduction. The materials will move forward relying on the inclination of the cylinder and the rotation of the kiln.

The characteristics of rotary kiln : 

Rotary kiln has such features of high output, low energy consumption and high burning effect.

The cement equipments with various types produced by Hongxing Machinery including rotary cement kiln and rotary kiln have reasonable price and high quality, and we can design the product manufacturing scheme according to your specific needs. If you want to learn more about cement equipments, feel free to contact Hongxing Machinery, and we will serve you with heart and soul.

The working principle of rotary kiln : 

Rotary kiln is the main equipment for cement production. The raw materials go from the kiln tail into the cylinder for calcinations. Due to the inclination and slow rotation of the cylinder, the materials will roll along the peripheral direction and also have compound movement along the axial direction from the high end to low end. Inside the kiln, the raw materials will have such technical processes as decomposition, calcinations and cooling, and become cement clinker and then will be discharged from the low end of the kiln cylinder and go into the cooling machine.

Rotary kiln is a high-temperature calcination equipment, which is also known as rotating kiln, lime pit, kiln dryer and calcining kiln. Rotary kiln can be used to calcite many kinds of materials. Rotary kiln can be classified into limestone rotary kiln, lime rotary kiln, and cement rotary kiln according to different roasting materials.

Rotary kilns are mainly used in building material industry and chemical industry, for example. calcining cement clinkers. Rotary kiln can also be used to roast some weak magnetic materials with high temperature for they are too weak to direct operation by magnetic separator. Then the materials can be magnetic separate after being strengthened their magnetism.

Besides, rotary kilns are mainly used in lime production line to calcite dolomite and limestone. Limestone rotary kiln is also called lime kiln. Limestone will be decomposed into limes during being calcited with high temperature in limestone rotary kiln.
