The burner is an important piece of equipment in the cement clinker production process. The burner used in this paper is specially equipped with swirl vanes in every channel, as shown in Fig. 1. With this special structure, a strong inner recirculation zone and outside recirculation zone can be established in the rotary kiln.
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 ROTAX-2's impressive graphite seals use a staggered arrangement. Two rows of graphite blocks are held in place ...
