200TPD durable widely used quick lime rotary kiln with ISO CE approved

Introduction

Rotary kilns are an advanced thermal processing tool used for processing solid materials at extremely high temperatures in order to cause chemical reaction or physical change. They are commonly used to carry out processes such as calcination, thermal desorption, organic combustion and heat setting.

YUHONG Quick Active Lime kiln can work with vertical preheater and vertical cooler to achieve the advantages like high use ratio of raw materials, complete calcination, even quality, good quality lime, high capacity output, environmental and energy saving, simple operation and longer working life. This kiln is very suitable for limestone calcination for industries like metallurgy, chemical, construction materials and etc.

　Although rotary kilns were originally developed for use in cement industries, due to their flexibility, they are now adopted for many industrial applications. A cross-section view of a rotary kiln is shown in Figure 1 below

　　A typical rotary kiln is made up of a rotating cylinder, sized specifically to meet the retention time and temperature requirements of the material to be processed [4]. The kiln is usually placed at an incline to allow gravity assist the materials to move through the rotating cylinder.

　　Although the rotary kilns are custom made around the material to be processed, some components are basic for rotary kiln [2], which are; drive assembly, riding rings, thrust rollers, trunnion wheels, discharge breeching, product discharge, exhaust gas system, refractory, heat source, raw material feed, air seal and kiln shell.
