Rotary kiln belongs to building materials equipment category, mainly used for calcination of cement clinker, but also for the production of refractory materials such as calcination of clay, limestone and slag drying. The rotary kiln has simple structure, convenient and reliable production process control, few vulnerable parts, and high operation rate. It is a necessary equipment for cement plant calcination. It is also widely used in metallurgy, chemical industry, construction and other industries. Our company customizes and designs various large, medium and small rotary kilns according to the different needs of customers. During the application process, it runs smoothly and has high efficiency...Learn More
