Φ1.6x32--Φ4.7x72(M) Rotary Kiln Customizable Reliable Performance
Introduction of Rotary kiln:
Rotary kiln is composed of gas flow, fuel combustion, heat transfer and material movement. Rotary kiln is how to make the fuel can be fully burned, and the heat of fuel combustion can be effectively transferred to the material. After the material receives the heat, a series of physical and chemical changes occur, and finally the finished clinker is formed.
Rotary kiln Application:
Rotary Kiln is used for making of cement clinker and there are dry and wet methods to make cement. metallurgy chemical kiln is used in metallurgy industry and ironworks for lean iron ore, chromium ore and ferronickel ore calcimine. Rotary kiln is used for calcimine of high aluminum vandal ochre in refractory material industry; for calcimine of calotte and aluminum hydroxide in aluminum manufacturer; for claiming of chrome sand ore and chrome powder ore in chemical plant.
Classification of Rotary Kiln:
According to the appearance, it is divided into variable diameter rotary kiln and diameter rotary kiln; According to the purpose, it can be divided into cement rotary kiln, ceramsite sand rotary kiln, kaolin rotary kiln, lime rotary kiln, etc.; According to different energy supply effects It is divided into gas-fired rotary kiln, coal-fired rotary kiln, and mixed fuel rotary kiln.
(1) Variable diameter rotary kiln
Rotary kiln with varying front and back diameters. Generally, the diameter changes about 30cm before and after. Compared with the traditional diameter rotary kiln, it has the advantages of energy saving and high yield, but the variable diameter rotary kiln is difficult to process, and it is more difficult to process than the traditional diameter rotary kiln. More stringent equipment requirements.
(2) Diameter rotary kiln
It is a rotary kiln with the same front and back diameter. Our common type of rotary kiln was invented in 1883 by German Dietz. After years of evolution, the rotary kiln has become a universal equipment. It has better effect and higher output than traditional shaft kiln. The processing is simple, but it consumes more energy than the variable diameter rotary kiln.
Outstanding Advantages of Rotary Kiln:
(1) The technical performance and operation of the rotary kiln determine the quality, output and cost of the company's products to a large extent. "As long as the big kiln turns, there will be tens of thousands", the folk song is a vivid description of the importance of rotary kilns in production.
(2) In the building materials industry, in addition to calcination of cement clinker, rotary kilns are also used for calcination of clay, limestone and slag drying; in the production of refractory materials, rotary kilns are used to calcin raw materials to make their dimensions and strength stable. Increase and reprocess the shape.
(3) In the process of beneficiation, the lean iron ore is magnetized and roasted with a rotary kiln to change the original weak magnetism of the ore into a strong magnetism to facilitate magnetic separation.
