Brief introduction of rotary kiln
Rotary lime kiln is the key equipment of cement clinker dry -process and wet -process production line, and is also used in various industries such as metallurgical , chemical industry ,building refractory ,environ mental protection industry , etc .
Application of the Rotary lime kiln:
Rotary lime kiln in building material, metallurgy, chemical industry, environmental protection and many other production industry, rotary drum equipment is widely used in mechanical, physical or chemical processing of solid material, such equipment is called the rotary kiln. The application of rotary lime kiln originated in cement production, rotary lime kiln is widely used in many industrial fields, and more and more important in the production, become the core of the enterprise production equipment accordingly.In the field of application of rotary lime kiln, the cement industry in the largest number.
Design feature of the Rotary lime kiln :
The rotary lime kiln is composed the cylindrical shell ,roller supporting device ,supporting device with thrust roller ,driving gear unit moveable kiln head ,sealing device at kiln inlet ,coal dust pipe device etc.
The kiln shell is designed to keep some inclination to level .It is supported by the roller supporting device and equipped with thrust roller device to control the up and down moving of the shell .The driving system is equipped not only the main driving gear unit but also the auxiliary driving used to keep the shell rotating even when the main power is broken so as to prevent the shell from any bending and distortion .As the kiln head and tail are sealed by advanced technology ,the sealing of the kiln is fairly reliable.
Working principle of the chemical Rotary lime kiln:
Rotary lime cylinder is heated rotating parts, USES the high quality calm steel plate welding, cylinder by belting leather bearing in 2 ~ 7 block sliding or rolling bearings supporting device, and in one or a few bearing block device is equipped with mechanical or hydraulic gear wheel, to control the axial channeling motion of the cylinder;Drive through the cylinder gear ring in the middle of cylinder speed rotary as required;Due to the need of installation and maintenance, the larger kiln is equipped with the cylinder at very low speed rotation auxiliary transmission device;To prevent cold air into the dust and flue gas overflow cylinder, the cylinder of the feeding end (tail) and the discharge end (head) with reliable preheater and kiln head, sealing device.Cylinder hole temperature test sampling devices are set up, on the kiln hood is equipped with load cell, the kiln of large size also can install infrared thermometer for cylinder monitoring temperature measurement.
