It is particularly suitable for large-scale production and can work continuously for a long time. ... Efficient production: The design of the roller kiln ...
Suzhou Huike Technology Co., Ltd. was established in October 2000. It is located in Xinzhuang Industrial Development Zone, Changshu City, a famous historical and cultural city, with a registered capital of 30.81 million yuan.
The purpose of tyres (often called riding rings) and rollers is to support the kiln and allow it to rotate with minimal friction. Rotary kilns are among the largest items of permanently moving industrial machinery, the largest examples …
In the FEECO design process, once we have engineered a rough design of the rotary kiln, we use several computer programs to help predict and model how the material will behave in the rotary kiln we have designed. We review the combined analyses, and if our design does not meet the appropriate criteria, we adjust accordingly. Conclusion
