Ceramic Roller Kiln Reheating Mullite Insulation Brick For Cement Industry
Product Description:
Mullite insulation bricks are made from good quality and super pure raw materials, with strictly classified fillings according to their grades. These fillings can form a uniform pore structure after burnt during the process of production. Each grade of products has unique design to meet different thermal, physical and chemical demands.
The most competitive price,good quality,safety packing,prompt delivery time,and excellent after-sales services.
Lighter weight,Low thermal conductivity,low impurities,high insulating properties,high CCS and exact tolerance.
