Description

Огромные 1масштабы и непрерывный рост применени  бетона и железобетона в строительстве требуют больших количеств крупного заполнител  {щебн , грави ). Эти заполнители должны быть очищены от посторонних примесей в соответствии с требовани ми стандартов в части предельно допустимого содержани  в них последних. Дл  очистки щебн  от посторонних примесей (глины, ила, пыли и т. п.), как правило , примен етс  промывка водой. Процесс промывки характеризуетс  значительным расходом воды и необходимостью наличи  утепленных помещений (в северных районах) дл  предотвращени  смерзани  щебн  при отрицательных температурах. Промывка щебн  в южных районах часто затруднена из-за недостатка или отсутстви  местных источников воды.Huge scale and continuous growth in the use of concrete and reinforced concrete in construction require large quantities of coarse aggregate {rubble, gravel). These fillers must be free from impurities in accordance with the requirements of the standards in terms of the maximum permissible content of the latter. To clean rubble from impurities (clay, silt, dust, etc.), water washing is usually used. The washing process is characterized by a significant water consumption and the need for insulated rooms (in the northern areas) to prevent rubble from freezing at low temperatures. Flushing rubble in the southern regions is often difficult due to the lack or absence of local water sources.

Предлагаемый способ позвол ет производить обогащение щебн  без применени  воды.The proposed method allows the concentration of rubble without the use of water.

Сущность способа заключаетс  в применении вращающегос  сущильного барабана дл  обогащени  щебн . В барабане в процессе перемешивани  зерен щебн  налипшие на них, но достаточно высушенные ностороиине примеси истираютс  и отдел ютс  от поверхности зереи с последующим удалением их из щебн  путем грохочени .The essence of the method is to use a rotating substantial drum to enrich the rubble. In the drum, in the process of mixing the grains of rubble, the impurities adhering to them, but sufficiently dried by nostroynia, wear off and separate the trees from the surface with their subsequent removal from the rubble by sieving.

Таким образом, в известных вращающихс  барабанных сушилках, используемых, как правило, дл  измельчени  в них высушенного материала , можно проводить обогащение щебн  с положительным эффектом , описанным выше.Thus, in the known rotary drum dryers used, as a rule, for grinding the dried material in them, it is possible to enrich the rubble with the positive effect described above.

Процесс оч;истки щебн  может протекать примерно следующнм образом . Загр зненный щебень направл етс  во вращающийс  сушильный барабан с температурой гор чих газов в нем пор дка 600-700°. При прохождении через барабан зерен щебн  посторонние примеси, налипшие на зерна, высушиваютс  и измельчаютс , превраща сь в сухую пь;;1ь. Дл  сушки примесей (в виде глины или асбестовой пыли) тре№ 141813 - .- 2 - ..#The process och; sources rubble can proceed approximately as follows. Contaminated rubble is directed to a rotating tumble dryer with a temperature of hot gases in it in the order of 600-700 °. During the passage of grains of rubble through the drum, the impurities adhering to the grains are dried and crushed, turning into a dry cake; To dry impurities (in the form of clay or asbestos dust), item # 141813 - .- 2 - .. #
