GEAR FOR METERING LOOSE MATERIALS FOR LIME-FIRING KILN Russian patent published in 1995 - IPC

FIELD: construction. SUBSTANCE: gear for metering is provided with rotor unloader with electric motor with reduction gear and shutters to increase accuracy of metering of components of mixture and to control proportion of dosages with mixing components in process of metering. Both metering gears are fitted with weight master units to set doses of coke and lime mounted on weight platforms with weight transducers electrically connected to electric motors of feeders of coke and lime and to electric motor of rotor unloader. Weight transducers are coupled to secondary instruments, electronic unit and comparator controlling process of simultaneous unloading of coke metering gear and of lime loading gear by points and of uniform mixing over the whole volume of skip. EFFECT: increased accuracy of metering of components of mixture. 1 dwg
