Abstract
A rotary kiln sealing system and rotary kiln equipment are provided. The rotary kiln sealing system includes a first housing and a second housing. The second housing is annularly disposed outside the first housing in space, and a first gap is left between the first housing and the second housing. An elastic compensation joint is disposed outside the second housing.
