Rotary Kiln

The wet rotary kiln is recognized as the category of building materials and equipment. The rotary kiln is composed of cylinder, supporting device, supporting device with baffle wheel, transmission device, movable kiln head, sealing device of kiln tail, coal injection pipe device, etc. Wet rotary kiln plays an important role in metallurgy, chemical industry, building refractories, environmental protection, and other industries. 

The cylinder body of the rotary kiln is rolled up by a steel plate. The cylinder body is lined with refractory lining and has a specified gradient with the level. It is supported by three-wheel belts on each supporting device. A large ring of teeth is fixed on the inner cylinder body of the span near the wheel belt at the feeding end with a tangential spring plate, and a pinion meshes with it. In normal operation, the main drive motor transmits power to the open gear device through the main reducer to drive the rotary kiln.

This series of rotary kilns is a large-scale calcining kiln with advanced international level developed by the company together with Beijing Institute of Mining and Metallurgy, Changsha Institute of Mining and Metallurgy and Suzhou Institute of Nonmetallic Mine Industry. Compared with traditional kiln type, this series of products can increase output by 30%, reduce heat consumption by 40%, discharge flue gas temperature < 250 C, facilitate dust collection and meet the requirements of modern energy saving, consumption reduction, and environmental protection.

Pengfei rotary kiln (Rotary kiln, titanium dioxide kiln, sintering furnace, industrial kiln, kiln, oxidizing pellet) has specifications of 3.2*52m, 3.5*54m, 4.0*60m, 4.3*64m, 4.8*74m, 5.0*78m. Pengfei rotary kiln is the main equipment for calcining cement clinker. It has been widely used in cement, metallurgy, chemical industry, and other industries. The equipment consists of a cylinder body, supporting device, supporting device with gear wheel, transmission device, movable kiln head, sealing device at kiln end and combustion device.

Domestic demand and import and export of aluminum alloys and rare earth silicon magnesium alloys in China have increased rapidly, and the consumption of magnesium has also increased dramatically, reaching 50,000 tons in 2010. In order to make full use of dolomite resources in various regions and improve industrial structure, Jiangsu Pengfei Group has developed and manufactured magnesium rotary kiln.

Jiangsu Pengfei Group independently developed rotary kiln calcination system. In 2003, it was granted two patents for invention. In 2006, Pengfei Cement Rotary Kiln was awarded "China Building Material Machinery Industry Famous Brand", "Jiangsu Province Famous Brand". In 2007, it was awarded the title of "China Famous Brand". On this basis, Su Pengfei Group jointly developed with Southeast University and Yancheng Institute of Technology-Cement Kiln Disposal Industrial Waste and City Municipal garbage technology and equipment

Jiangsu Pengfei Group has an annual manufacturing and processing base of 300,000 tons of machinery and equipment with 13 m diameter vertical car, 12 m diameter, 40 die hobbing processing capacity, annealing furnace 8*20 m, maximum lifting capacity 400 tons, meeting the manufacturing requirements of rotary kiln and ball mill below 10 m. Large-scale preheater, rotary kiln, tube mill, vertical mill, cooling machine and other main equipment are all self-developed and manufactured.

Activated lime is widely used in steel, alumina, magnesium, calcium carbide and power plant desulfurization and paper-making industry. Activated lime is an important auxiliary raw material for steel-making. The use of activated lime has a series of characteristics, such as improving the quality of steel, increasing production, reducing steel consumption and cost, and stabilizing operation.
