subject: Rotary Kiln Calcination Function Of Process [print this page] Rotary kiln calcination function of process
Professional rotary kiln factory Jiangsu Zhongbo machinery, the factory has a strong production team and many years production manufacture rotary kiln by the exquisite technology, greatly welcomed by customers, the senior Red Star Machinery below explain the rotary kiln roasting features introduced.
Cement 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.
1, the rotary kiln has a chemical reaction function. Clinker formation process, a series of physical, chemical reaction in a phased manner to meet the requirements of different mineral formation on the heat, the temperature, but also to meet their time requirements, the ideal chemical reactors.
2, the rotary kiln is an inclined rotating cylinder, raw materials joined by the high end of the cylinder, in a continuous rotary motion of the kiln, the material from high end to low end of the movement, so the rotary kiln carried the function of conveying.
3, due to the fact that rotary kiln has a high temperature field and airflow stagnation for a long time thermal field, biodegradable pharmaceutical, chemical and other industries discharge toxic and hazardous waste.
4, where the vast majority of heavy metal elements in curing in the clinker, the formation of stable salts, to avoid the "garbage incinerators may produce secondary pollution.
Pulverized pulverized coal to the kiln by the kiln hood blower sprayed into the combustion heat generated by radiation, convection and conduction three kinds of heat transfer heat to the material.
7, the rotary kiln has a vast space and thermal field , which can provide sufficient air to the installation of the excellent combustion devices, to ensure full combustion combustion to provide the necessary heat for clinker.
