SCT Ceramic Inner Cylinder of Preheater has the properties of heat-resistance, corrosion-resistance, high strength, high hardness, good thermal shock resistance, large thermal conductivity and good anti-oxidation. With a life span twice or triple longer than the heat-resistant steel, the Ceramic Inner Cylinder reduces the production cost and are the ideal choice for the preheater of rotary kiln. Patent Number for Ceramic Inner Cylinder of Preheater: The drawing of SCT Ceramic Inner Cylinder of Preheater Advantages of Ceramic Inner Cylinder of Preheater: Reduction of production cost because of the Improvement of the life; The plate-design avoids blocking of preheaters due to the inner cylinder’ breaking down, and just change the broken segment not the whole inner cylinder when broken down so that the productivity will be improved. No special tools and equipments will be needed when installing the segment due to its light weight, hence, reducing the labor force. The spaces between the segments will be filled by the powder of raw materials as the machine starts to operate. With the gas-solid separation of cyclone, the efficiency of heat exchange reaches the level of whole inner cylinder, reducing the heat loss and energy consumption. Reduction of dust-emission, relieve the load of Electrostatic Precipitator (EP), more friendly to the environment.
