The rotary kiln is refers to the rotation calcining kiln, belongs to the building materials of equipment. The rotary kiln according to deal with different materials can be divided into cement kiln, metallurgy chemical kiln and linme kiln. Kiln simple structure, convenient and reliable control of the production process, the vulnerability of small, high rates, the plant is calcined high-grade cement machine, but also widely used in metallurgical, chemical, construction and other industries.
Factors affecting the material proportion of rotary kiln include the following few points:
1. There are many factors affecting the strength of clinker, in addition to the effect of the dosing regimen, which mainly influenced by the burning process of clinker ( including the influence of cooling ). Though the rotary kiln with same dosing regimens, if it with different calcined systems, the composition of clinker mineral is different and the mineral crystal shape also different, and the demonstrated strength will be a big difference.
2. The temperature is low in winter, which means greater heat loss of the kiln body. As with the vertical kiln, the temperature inner the rotary kiln not only declined but the temperature is also uneven, which is not suitable for the calcining of the clinker leading the quality of clinker may be reduced. Therefore, the heat consumption of clinker should appropriately be improved in winter for the vertical kiln. If do not improve heat consumption of clinker, often can reduce clinker strength, usually, in shaft kiln cement plant in winter than in summer low intensity. vibrating screen:http://www.hxjq-crusher.com/40.html
3. However, in winter the temperature is low and the clinker cools fast, the fast cooling is in favor of improving the content of tricalcium silicate. Compared with slow cooling, the content of tricalcium silicate is generally higher when the clinker cools fast. For some rotary kilns with bad cooling ability, such as multiple cylinder cooler, rotary kiln, whose clinker cooling ability is not very good, therefore, in winter, due to the low temperature and high cooling speed, the actual content of tricalcium silicate increases as well as the strength. In the summer, because the clinker cooling speed is slow so that the clinker strength will decrease.
Red Star machine rotary kiln improvement of the structure and function: rotary kiln is generally adapted to granular materials can also be used in part to mixed dry and sticky paste materials or materials with higher water content of materials approach. The advantages of the rotary kiln, large capacity, applicable to a wide range of flow resistance, the operation is to allow a larger range and easy to operate.
Red Star Machines Corporation in order to make more prominent advantages of the rotary kiln, rotary kiln structure and function has been improved.
Compared to a rotary kiln can be debugged using the mosaic structure of the drive gear: with a spring steel plate transmission gear structure, the kiln cylinder after machining, gear inlaid cylinder, concentricity, the stiffness of the kiln better, run more stable, small vibration, large kiln structure.
