Is The Orientation Of A Rotary Kiln Important

Rotary Kiln Ispatguru. Dec 26 2019 The alignment of long rotary kilns is critical for the load distribution on the riding rings and the shell. Thrust rollers Thrust rollers prevent the drum from drifting or moving horizontally by pushing against the riding rings. The trunnion wheels act as the cradle for the rotating drum shell. Get Price

Cement Kilns: Design features of rotary kilns

2021-5-19  As mentioned above, a rotary kiln is essentially a rotating beam, so its tendency to sag between the supports means that the distance between the supports must be limited, and longer kilns must therefore have more tyres. The earliest kilns had only two supports, so that there was no need to confront the problem of kiln
