Abstract
Изобретение относитс к обогатительным процессам и может быть использовано дл получени из отвальных золошлаковых смесей ТЭС остеклованных фракций с размерами частиц 0,3-5 мм. Целью изобретени вл етс обеспечение возможности эффективного разделени смесей с повышенным содержанием мелких фракций 0,3-5 мм и увеличение их выхода в готовом продукте. Дл этого смесь в процессе подачи смачивают с поверхности распыленной водой в количестве 2-3 л/м2 поверхности смеси и выдерживают в течение 20-40 с. Затем провод т орошение смеси на грохотах с возрастающим расходом воды по ходу движени смеси при суммарном расходе воды 0,8-1,0 т/м3 смеси.Длину зоны орошени устанавливают равной 0,5-0,7 общей длины зоны грохочени .Устройство,с помощью которого осуществл ют способ,включает приемный бункер 1,вибропитатель 2,транспортер 3 узла подачи смеси с установленной в зоне загрузки распыл ющей форсункой, грохот 5 с двух русными ситами, многощелевую систему орошени с увеличивающимс регулируемым размером щелей, шлакоприемный короб 9, пульпопровод 10 и транспортер 11 отбора готового продукта. Соотношение размеров чеек сит нижнего и верхнего русов грохота выполн ют равным 0,15-0,20. 3 ил.The invention relates to beneficiation processes and can be used to obtain vitrified fractions with particle sizes of 0.3-5 mm from waste ash-slag mixtures of thermal power plants. The aim of the invention is to enable effective separation of mixtures with a high content of 0.3-5 to 5 mm fine fractions and an increase in their yield in the final product. For this, the mixture is wetted from the surface with sprayed water in the amount of 2-3 l / m 2 of the surface of the mixture and kept for 20-40 seconds. Then, the mixture is irrigated on screens with increasing water consumption during the mixture movement with a total water consumption of 0.8-1.0 t / m 3 of the mixture. The length of the irrigation zone is set to 0.5-0.7 of the total length of the screening zone. by means of which the method is carried out, includes a receiving bin 1, a vibratory feeder 2, a conveyor 3 of the mixture supply unit with a spray nozzle installed in the loading area, a screen 5 with two brown screens, a multislot irrigation system with an increasing adjustable slot size, a slag receiving box 9, slurry pipe 10 and transport p 11 selection of the finished product. The ratio of the cell sizes of the screens of the lower and upper rushes of the screen is equal to 0.15-0.20. 3 il.
