Description
Известные способы сушки брикетов из медно-пиритной рудной мелочи , содержащих некоторое количество гашеной извести (5-7%), не позвол ют получить достаточную прочность брикетов.The known methods of drying briquettes from copper-pyrite ore fines, containing some quantity of hydrated lime (5-7%), do not allow to obtain sufficient strength of briquettes.
Дл увеличени .прочности брикетов предложено вместо естествен ной сушки на воздухе примен ть сушку при температуре 50-75° в атмосфере газа, содержащего 5% и выше двуокиси углерода.In order to increase the strength of briquettes, it has been proposed to use drying at a temperature of 50-75 ° C in an atmosphere of gas containing 5% and higher carbon dioxide instead of natural air drying.
Обработка брикетов заключаетс в искусственной карбонизации, совмещенной с процессом сушки, при определенных температурном интервале и длительности процесса.Briquette processing consists of artificial carbonization combined with a drying process, at a certain temperature range and process duration.
Искусственна карбонизаци заключаетс в обработке брикетов газом, содержащим от 5% и выше (до любого содержани ) углекислоты . Процесс может быть осуществлен за счет углекислоты топочных газов или отход щих газов известково-обжигательных печей. Температура в карбонизационной камере поддерживаетс в пределах 50-75°.Artificial carbonization consists in treating briquettes with gas containing from 5% and higher (up to any content) carbon dioxide. The process can be carried out using carbon dioxide flue gases or flue gases from lime kilns. The temperature in the carbonization chamber is maintained between 50 ° and 75 °.
Длительность процесса карбонизации составл ет 15-25 час в зависимости от начальной влал :ности свежезапрессованных брикетов. Параметры режима карбонизации установлены на основе научно-исследовательских работ, выполненных Гннцветметом. При выходе из карбонизационной камеры брикеты получаютс в 1,5-2,0 раза более прочными , чем при естественной сущке.The duration of the carbonization process is 15-25 hours, depending on the initial rate of freshly pressed briquettes. The parameters of the carbonization regime are established on the basis of research works carried out by Gntsvetmet. When leaving the carbonization chamber, the briquettes are obtained 1.5-2.0 times more durable than with the natural substance.
