Circular Cooler is using air-blast way for cooling sinter in sintering plant, generally the sinter temperature is 700-800℃ when it enter into cooler at the first beginning, the Grate Wing Pallet Cars will run the Circular Cooler a round. After completion of the sinter cool down, the temperature will be dropped down to 120℃ below usually. The cooling sinter will be discharged in the unloading zone of circular cooler.

In order to enhance the production efficiency and the sinter quality, reduce energy consumption, and put things right once and for all to completely solve the problem of air leakage, Qin Huang Dao Hongtai Machinery Company researched and developed a new kind of sealing system named "Circle cooler inclusive type mechanical sealing system ". It is a patent production and easy to maintain.

The features:

• Energy-saving and consumption reducing: Inclusive type mechanical sealing system completely solve the      problem of air leakage of circle cooler, air leakage rate at the place of dynamic and static rubber will be cut down over 70%,and cooling effect increase above 50%, effectively to avoid burnout of convey belt. Blower will not  need to work with full load. Under the same cooling effect, total electric power of blower will save 400KW/H or above.

• Productivity increasing:      Because of cooling effect raised greatly, circle cooler can cool the      sinter promptly which produced by sintering machine and convey it      smoothly, thereby lessen influence on sintering machine with full load      since previously the sintering cannot cool immediately on circle cooler.

• Spot environment better:      Because of air leakage rate reducing greatly by adopting inclusive type mechanical      sealing system, there will not be dusty scene appeared on site.

• Waste heat recovery power generation increasing: Because of good sealing effect, air temperature      increased obviously during the period of waste heat recovery in the circle      cooler, and improved the productivity of waste heat recovery.

• Labor intensity reducing:      When the outage maintenance, it will decrease extraction around the track by labor clearing, no need to change the dynamic and static rubber sheet, thereby decrease the labor intensity of workers.

• This system is easy to maintain
