Photographer: Jack Xia.  CHINA .Tianjin BELL electric actuator working scene：420 m2 sintering machine what is sintering ?   Application of Tianjin BELL electric actuator in sintering BELL-400 electric actuator 1 what is sintering:            Sintering production is to mix the ore, solvent and fuel according to a certain proportion and mix them into particles through the mixer. The sintering is evenly placed on the sintering machine, ignited, and sent to the ring cooler for cooling after sintering. The cooled particles are screened out to be qualified particles, and the qualified particles (sinter) are sent to the blast furnace for smelting.  2 A pplication of Tianjin BELL electric actuator in sintering     Tianjin bell actuator bell-400 is used in a 420 square meter sintering machine. It uses the negative pressure generated by the operation of the main exhaust fan to burn the flame ignited on the ...
