A rotary kiln for cement is only as efficient as the seals on its inlet and outlet zones. After all, if false air enters the kiln system, fuel consumption goes up, production output goes down, and operating expenses skyrocket. The ROTAX2®'s impressive graphite seals use a staggered arrangement. Two rows of graphite blocks are held in place ...
