rotary kiln operational formula

Rotational kiln is a cylinder calcination equipment, also known as rotary kiln, after increasing its speed, the production and quality of clinker has been greatly improved, and some other problems have also been a very good solution.. First, the influence on the clinker production and quality. The output of clinker is between 880--920 ton / day before rotary kiln speed increase, but 1000

    A rotary seal used to prevent the escape of contaminates from a rotating kiln incinerator. The rotating seal combines a rotating disc plate which is attached to the rotating kiln shell and four sets of non-rotating carbon seal bars housed in a primary and secondary housing and which rub on the sides of the disc. A seal air system is used to create a positive pressure in a chamber between the
