Iron plate size in rotary kiln

Aug 31, 2021

Rotary kilns are a vital part of industrial processing, helping to carry out a wide range of chemical reactions and physical changes in hundreds of materials. The process of sizing a rotary kiln to meet the specific requirements of a given application is incredibly complex, and must take several factors and analyses into consideration
