gomine - Rotary kiln

As a kind of commonly used calcining equipment, rotary kiln is widely used in construction, building materials, metallurgy, chemical industry and environmental protection industry. In addition to the calcination of clay, limestone, slag, iron, aluminum, copper, zinc, iron ore, concentrate and intermediate materials, it also has thermal reaction, heat exchange, degradation and utilization of waste and other functions.

>>Building Materials Industry
In addition to the calcination of clinker, the kiln can also be used for the drying of limestone, slag, and clay, etc. In refractory material production, the rotary kiln is used to calcinate and keep a stable size of the raw material and improve the strength.

>>Ore Dressing Industry
In the ore processing, rotary kiln can be used to magnetizing roast the deletion iron to improve the magnetism, which is better for the magnetic concentration.

>>Metallurgical Industry
It is usually used for the sintering of ore, concentrates, intermediate materials and for the smelting of iron, aluminum, copper, zinc, tin, nickel, tungsten, chromium, file, and other non-ferrous and ferrous metal.

>>Environmental Protection Industry
The cement kiln is used in hazardous waste and other waste burning. After the kilning process, waste can be harmless and be used as a resource.

>>Chemical Industry
Rotary kiln for the production of soda, calcined phosphate fertilizer, barium sulfide, etc. The mode of phosphoric acid production by rotary kiln can date back to the 1960s. After near half a century, this process is developed with the advantages of low energy consumption and no use of sulphuric acid, etc.

Rotary kiln is a cylinder set at a certain angle. When a rotary kiln works, the cylinder rotates to make the materials inside get fully mixed and contacted. Coal injection combustion at kiln head produces a lot of heat that is transmitted to the materials by the fire radiation, scorching air exchange and the transmission of the body. Materials steps forwards under the effect of gravity and the rotation of the cylinder.

It mainly consists of the body, a driving device, a supporting device, blocking wheel, kiln head sealing device, kiln tail sealing device and kiln hood.

Flexible axial movement of the cylinder. The kiln cylinder is made of high-quality sedation steel plate. The cylinder is supported on the supporting device of the sliding bearing of 2×7 gears through the wheel belt, and a mechanical or hydraulic retaining wheel is arranged on one or more of the supporting devices. The customer can flexibly control the axial movement of the cylinder.
Flexible rotation of cylinder. The driving device rotates the cylinder by the gear rings set in the middle part according to the required speed.
Convenient installation and maintenance. The larger-sized rotary kiln is equipped with assistant driving device that is rotating at very low speed. This arrangement is to meet the need of regular check and some maintenance.
Well-sealed cylinder. In order to prevent cold air from entering and smoke dust spilling over the cylinder, reliable kiln tail and kiln head sealing device is arranged at both ends of the cylinder.

1. According to the exterior, it can be divided into variable-diameter rotary kiln and path rotary kiln;

2. According to the usage, it can be divided into the cement rotary kiln, magnesium metal rotary kiln, ceramsite sand rotary kiln, kaolin rotary kiln, lime rotary kiln, etc.

3. According to the fuel, it can be divided into gas rotary kiln, coal rotary kiln and mixed-fuel rotary kiln.
