Abstract
Изобретение относитс к измельчению полезных ископаемых и может быть использовано при производстве строительных материалов. Цель - интенсификаци измельчени песка и утилизаци отхода. При помоле песка ввод т добавку - отработанную эмульсию листопрокатного отделени алюминиевого производства на основе трансформаторного масла в количестве 0,008-0,05% от массы песка. 1 табл.The invention relates to the grinding of minerals and can be used in the manufacture of building materials. The goal is to intensify the grinding of sand and disposal of waste. When grinding the sand, an additive is introduced - the waste emulsion of the sheet-rolling section of aluminum production based on transformer oil in an amount of 0.008-0.05% by weight of sand. 1 tab.
Description
Изобретение относитс к измельчению полезных ископаемых и может быть также использовано в других отрасл х промышленности , в частности, при производстве строительных материалов.The invention relates to the grinding of minerals and can also be used in other industries, in particular, in the manufacture of building materials.
Цель изобретени - интенсификаци измельчени и утилизаци отхода.The purpose of the invention is to intensify the grinding and disposal of waste.
Пример. Состав отработанной эмульсии листопрокатного отделени алюминиевого завода, %;Example. The composition of the waste emulsion sheet rolling department of an aluminum plant,%;
Трансформаторное масло85Transformer oil85
Олеинова кислотаюOleic acid
Триэтаноламин5Triethanolamine5
В процессе производственного цикла под воздействием высоких температур часть олеиновой кислоты образует олеат алюмини . Уточненный состав эмульсии, %: Трансформаторное масло85During the production cycle, under the influence of high temperatures, part of the oleic acid forms aluminum oleate. Specified composition of the emulsion,%: Transformer oil85
Олеинова кислота8Oleic acid8
Олеат алюмини 2Aluminum oleate 2
Триэтаноламин5Triethanolamine5
Добавку в количестве 0,008-0,1 % от веса сухого материала ввод т в барабанную шаровую мельницу, в начальной стадии помола вместе с песком и водой. Интенсифи- цирующее действие оценивают поAn additive in the amount of 0.008-0.1% by weight of dry material is introduced into a drum ball mill, in the initial stage of grinding, along with sand and water. Intensifying action is assessed by
изменению удельной поверхности песка на приборе ПСХ-2 после измельчени в течение 10 мин.the change in the specific surface of the sand on the PSC-2 device after grinding for 10 minutes.
Результаты испытаний приведены в таблице.The test results are shown in the table.
Как видно из таблицы, применение добавки в количестве 0,008-0,05% от массы песка обеспечивает прирост удельной поверхности на 56-73%, тогда как известна добавка - липокаин дает прирост удельной поверхности на 25-46%. Увеличение добавки свыше 0,05% не приводит к существенному изменению удельной поверхности песка.As can be seen from the table, the use of an additive in the amount of 0.008-0.05% of the mass of sand provides a specific surface area increase of 56-73%, while the additive is known - lipocain gives a specific surface area increase of 25-46%. An increase in the additive over 0.05% does not lead to a significant change in the specific surface of the sand.
