Abstract:

Unburnt bricks are widely used in furnace lining of active lime rotary kiln,because of their advantages of low cost and no chromium pollution.In the burning zone of active lime rotary kilns of WISCO,phosphate bonded bricks take the place of magnesite\|chrome bricks and magnesia spinel bricks,which extends the lining life to more than three years.With many years applied experiences for unburnt bricks,and based on collection and compilation and analysis on the industry data,WISCO is responsible for setting industry standards and specifications for unburnt bricks in active lime rotary kilns to guarantee the stable operation of lime rotary kiln.
