  • Refractory Material For Cement Rotary Kiln AGICO Cement

    For example, it is difficult to form a stable kiln skin by using magnesite-spinel brick in the rotary kiln sintering zone, which is easily affected by the atmosphere and heat load, so its service life has always been the bottleneck of the cement kiln. Secondly, it has high thermal conductivity, wastes resources and is easy to peel off.

  • Magnesia Iron Spinel Bricks Kiln Refractory Bricks

    In order to make the kiln skin and the lining brick firmly bonded, in addition to the chemical composition of the refractory brick, the structure of the brick is also very important. There should be a certain amount of uniformly distributed pores to facilitate the infiltration of the kiln melt to form a mechanical anchor.

  • Refractory lining material recommendation for cement

    In the global market, Magnesia spinel brick is widely used in cement kiln linings, but Magnesia brick is with higher thermal conductivity compared with China high alumina with SiC. Today silica-mullite brick is the best option for large scale cement rotary kiln. And thermal shock resistant castable are widely used for the outlet zone.

  • Introduction of rotary kiln structure

    It is the main body of the rotary kiln. The thickness of the kiln shell steel plate is about 40mm. Near the tire ring, because the bearing capacity is relatively large, the kiln shell steel plate here is thicker. The interior of the kiln shell is covered with a layer of refractory bricks of about 200 mm.
