Rotary kiln sintering process schematic diagram is shown in the figure, which of raw slurry is sprayed into the rotary kiln from the kiln inlet,pulverized coal combine with the primary air send by the coal injection tube from the kiln inlet and air blower to form gas-solid two-phase flow to enter into the kiln head,and combusted together with the secondary air indrawn by the cooler,heat generated and raw slurry reverse run. Through drying, preheating, decomposition, sintering, and cooling zone,raw slurry is finally processed into final product - clinker,and sent to the next process.
The temperature of the burning zone directly determine the characteristics of the clinker, and therefore the precise measurement has become the most critical part of the rotary kilnsintering process. Due to the rotation of the kiln, the thermocouple is difficult to install and apply. Since the kiln smoke interference ratio pyrometer own limitations, the measured temperature of the single point value is often far from the true value, and showed large fluctuations. In order to eliminate the defect of the temperature measurement, where attempts to explore a new firing status recognition method, the state identification to achieve more reliable and accurate firing.
Rotary kiln is a kind of thermal equipment, heating materials. It is widely applied in the fields of cement building materials, nonferrous metallurgy, ferrous metallurgy, refractory material, chemical materials and paper making. The rotary kiln has simple structure, convenient and reliable control during the production process, a few wearing parts, high operation ratio. The rotary kiln produced by our factory has rugged structure, smooth operation, high quality outlet products. Besides, we provide our customers with advanced, efficient vertical heating device, and cyclone heating device.
Rotary kiln also named rotate calcination kiln, belongs to making building material equipment. It can be divided into cement kiln metallurgy chemical rotary kiln and lime kiln according to processing different material.The cement kiln is mainly used in calcination clinker. And the cement kiln also can be divided into dry production cement kiln and wet production cement kiln. The metallurgy chemical rotary kiln is mainly used in metallurgical industry like magnetizing roasting poor iron in steel iron plant, silicon thermal to roast active lime and dolomite which used in steel iron plant and ferroalloy plant.
Rotary kiln is used for making of cement clinker and there are dry and wet methods to make cement. Metallurgy chemical Rotary 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 och 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.
