Alumina Rotary Kiln

Rotary kiln refers to rotary calcining kiln (commonly known as rotary kiln), which belongs to building materials equipment category. Rotary kilns can be divided into cement kilns, metallurgical chemical kilns and lime kilns according to different materials. Cement kilns are mainly used for calcination of cement clinker, divided into two categories: dry production cement kilns and wet production cement kilns. Metallurgical chemical kilns are mainly used for the magnetic roasting of lean iron ore in the metallurgical industry; oxidation roasting of chromium and nickel iron ore; roasting high alumina bauxite ore in refractory plants and roasting clinker and aluminum hydroxide in aluminum plants; roasting chrome ore in chemical plants And minerals such as chrome ore powder. Lime kiln (i.e. active lime kiln) is used to roast active lime and light-burned dolomite used in steel plants and ferroalloy plants. Rotary kilns are divided into variable diameter rotary kilns and through-diameter rotary kilns according to their appearance. According to their uses, they can be divided into cement rotary kilns, ceramsite sand rotary kilns, kaolin rotary kilns, lime rotary kilns, etc., according to different energy supply effects. It is a gas-fired rotary kiln, a coal-fired rotary kiln, and a mixed-fuel rotary kiln.

Rotary kiln is a kind of thermal equipment calcines lump, bulk and slurry materials. It is widely used in cement & construction, non-ferrous metals, lime, ferrous metals, refractory materials, industrial chemicals, paper making industries etc. Our products advantages as follows: 1.New type technology is adopted by main driving system. Compared with traditional magnetic and dc speed regulation, its main driving system has the advantages like energy saving, environmental, wide speeding adjusting range, high performance and stable operation. 2. After the welding of bases for supporting devices of supporting roller and catching roller, vibration aging treatment should be applied for remove the welding stress. Then, use vertical lathe and boring-milling machine for integration fabrication. This process can guarantee the requirement of fabrication precision and dimension & location tolerance. Installation accuracy of rotary kiln is obviously improved. 3. Temperature measuring point is reserved at bearing base of supporting roller. It is mainly used for automation detection of kiln operation status by insert the measuring device.

Wet rotary kiln, as building material equipment, is widely used in metallurgy, chemical industry, building refractory material, environmental protection and other industries. The rotary kiln consist cylinder, supporting device, support device with retainer wheel, drive device, active kiln head, kiln end sealing device, coal injection pipe device and other components. Wet rotary kiln body shows a certain degree of tilt to horizontal level. The entire kiln body is supported by roller device. It also has retainer wheel device to control the kiln body in case it runs up and down. The drive system also has auxiliary drive that can make kiln body drive when major power is off and prevent kiln body bending and being out of shape besides major drive. Kiln head and kiln end sealing device uses advanced technology to ensure reliability of sealing.

The structure of kiln is simple, operate conveniently and reliably in life, less wearing parts, high rate of operation, it is the equipment to calcine high-grade cement in cement plant. Meanwhile, it is also widely used in metallurgical, chemical, construction and other industries. The rotary kiln produced by my company is with strong structure, operation smooth, high-quality products etc and can provide users with advanced high-performance vertical pre-heater, 5 degree cyclone pre-heater. Cement manufacturing consists of raw material grinding, blending, pre-calcining, clinker burning and cement grinding. In short, limestone and other materials containing calcium, silicon, aluminum and iron oxides are crushed and milled into a raw meal. This raw meal is blended and then heated in the pre-heating system to start the dissociation of calcium carbonate to oxide. The meal goes further into the kiln for heating and reaction between calcium oxide and other elements to form calcium silicates and aluminates at t a temperature up to 1450 centidegree: so called clinker burning. The cyclone system is attached to the rotary kiln by a riser duct. Secondary fuel is fed to the riser duct, the main fuel mixture, coal/petcock, fires the kiln. Reaction products leave the kiln as a nodular material called clinker. The clinker will be interground with gypsum and other materials to cement. The equipments we use in this whole production line are vibrating feeder, jaw crusher, impact crusher, cement ball mill, lifer, preheating system, cement rotary kiln and packing machine and so on. All the necessary equipments in this line can be provided by our factory. We have cement production line experts to design specific solutions for your preference.
