FIELD: glass industry.
SUBSTANCE: charge is unloaded onto the belt conveyor of the charge and cullet feed line into the glass-fired furnace by means of a feeder installed at the outlet of the receiving bunker of the mixer, and is performed either with one full portion, the mass of which is equal to the charge portion weight, which is prepared in the mixer, or in partial portions. When unloading onto the same conveyor from the glass pan dispenser a glass scoop portion having mass which is 2–4 times less than the weight of the full portion of the charge discharged from the receiving hopper, conveyor belt generates mix of "sandwich" with percentage charge / scrap glass (70–80):(30–20). To increase the amount of cullet and change of percentage of charge / scrap glass to value (20–30):(80–70), unloading of the charge from the receiving hopper onto the conveyor of the supply line of the charge and cullet to the glass-fired furnace is performed in partial portions, mass of which is multiple and 2–8 times less than weight of complete portion of charge discharged from mixer into receiving hopper. Mass of partial portions of the charge is controlled by means of strain-gauge weight sensors on which the receiving hopper rests. Productivity of the charge unloader from the receiving bin is reduced by 2–8 times compared to its initial capacity.
EFFECT: technical result consists in optimization of operation of dosed supply lines of charge and cullet to glass melting furnace and expansion of limits of percentage ratio of charge / scrap glass to higher content of cullet in a mixture using discrete weight scrap glass dispensers, having a limited volume, smaller than volume of mixer of charge.
