Rotary Kiln

Features

Introduction to rotary kiln

Rotary kiln is mainly used in the industrial field, such as mineral processing plants, cement plants, garbage disposal plants, lime production and so on, so it’s also called rotary cement kiln, rotary lime kiln, calcining kiln, clinker rotary kiln, etc.

Classification of rotary kiln

According to different purposes, rotary kiln can be classified into cement rotary kiln, lime rotary kiln and so on. Rotary kiln can be used for cement clinker calcinations and high-temperature calcination of lean iron ore, limestone and other materials.

Function of rotary kiln

What is the purpose of rotary kiln in industrial field? Rotary kiln is cylinder equipment for calcination of materials, mainly used for calcining raw cement materials into cement clinker in cement making field, and producing fertilizer and sulfur ore in the field of chemical. Cement rotary kiln works with a certain inclination angle about 3.5-6%. Low speed rotation of the rotary kiln makes materials in it rotate while rotating kiln burner jets flame constantly, to heat materials and make materials take physical and chemical reactions. Fote rotary calcining kiln is with good quality and high yield.

Other application of rotary kiln

Rotary kiln is mainly used for heating and sintering ores and other mineral materials in metallurgy, building materials and other fields, such as heating and sintering argilla, bauxite, limestone, cement, magnesium, alumina, aluminum hydroxide, high alumina products, refractory materials, fly ash, and other powdered material and mineral grain. Of course, lime kiln or lime rotary kiln is mainly used for the calcination of heating and sintering limestone.

Structure and working principle of rotary kiln

Rotary kiln is mainly composed of a tube of rotary kiln body, support device, sealing devices, feeding device, combustion devices of kiln head, etc. Rotary kiln is a round cylinder, mounted on several tugs inclined. After deceleration, the motor drives pinion to rotate the big rear wheel, so as to rotate the tube kiln body.

Cement rotary kiln

Cement rotary kiln is also known as cement kiln or rotary cement kiln, which is a very important device in cement manufacturing process. Cement rotary kiln is mainly used for calcining grinded fine cement raw meal into cement clinker under high temperature. Therefore, cement rotary kiln is called the heart of cement plant. In the building materials industry, rotary cement kiln is also used for calcining clay, limestone, slag and so on. Cement rotary kiln can also be used for manufacturing refractory.

Metallurgy rotary kiln

Rotary kiln extensively used in the field of metallurgy is also known as the metallurgy chemical kiln or metallurgy kiln. Metallurgy chemical kiln or metallurgy kiln is mainly used for calcining poor iron ore in steel plant, and roasting chromium, nickel, iron ore, etc. to enhance their magnetic materials for better sorting and other applications.

Lime rotary kiln

Lime rotary kiln is mainly used for the production of quicklime, and it can also be used for calcining dolomite, limestone, and so on. Combined scales seal is made at both ends of lime kiln, so the air leakage coefficient of Fote lime rotary is less than 10%. The using of composite refractory materials can reduce radiation losses of lime rotary. Lime rotary kiln is mainly composed of pre-heater, cooler, combustion chamber and other components.
