The new concept of the No-Bell Top® charger allows for better burden distribution in the blast furnace as well as a quick exchange of the chute system. The compactness of the No-Bell Top® System ensures an easy exchange of a double-bell system. With the flexible chute system of the No-Bell Top® it is possible to charge the burden and coke to any position in the blast furnace. It ensures that the coke is effectively directed and piled in the appropriate destination generating a better gas exploitation and lowers consumption of reducing agents. No-Bell Top® is also equipped with a quick changing device for the complete chute system.
The essential features of the No-Bell Top® are its reliable gas tightness to prevent leakage as well as precise and quick material distribution. The efficiency of existing furnace processes can be considerably increased and the emissions reduced. The consumption of reduction agents can be reduced and the performance of the blast furnace increased. Due to the cost savings, the return of investment could be less than one year.
Constant chute angle guaranteesperfect distribution due to superiorburden guidance
No lifting and lowering of the chute;this reduces torque and load to the gear guidance
Reduced wear due to low drop height of burden into the chute system
Several charging models possible (ring, spiral, sector, point, etc.)
Fast relocation of the charging position
Less energy consumption
Simple gearbox design with push rods
