    A rotary cement kiln consists of a slightly inclined tube made from steel plate and lined with refractory brick. The refractory is used to insulate the steel structure, which becomes soft and weak above 800 C. The kiln rotates between 30 and 250 revolutions per hour, taking in a raw mix at the upper end. The rotation of the kiln causes the mix
