Изобретение относитс к производству строительных материалов, иредназначено дл изготовлени легкого нористого заполнител дл бетонов.The invention relates to the production of building materials, and is intended for the manufacture of lightweight aggregate for concrete.
Известен способ производства керамзита, включающий операции введени в глинистое сырье эмульсионной органической добавки, гранул ции и обжига.A known method for the production of expanded clay, comprising the steps of introducing emulsion organic additive, granulation and roasting into the clay raw material.
Целью изобретени вл етс снижение объемного веса и повышение прочности керамзита .The aim of the invention is to reduce the bulk density and increase the strength of claydite.
Это достигаетс тем, что эмульсионную органическую добавку ввод т в процессе гранул ции сухого порошкообразного глинистого сырь . В качестве эмульсионной органической добавки используют эмульсию мазута в воде состава, часть: 1 мазута и 6 воды и органожелезистую эмульсосуспензию состава, часть: 1 мазута, 1 окислов железа, 6 воды.This is achieved in that the emulsion organic additive is introduced during the granulation process of dry powdered clay raw material. As an emulsion organic additive, use is made of a fuel oil emulsion in water of the composition, part: 1 fuel oil and 6 water and an organic iron composition emulsion suspension, part: 1 fuel oil, 1 iron oxide, 6 water.
Способ производства керамзита осуидествл ют следующим образом.The production method of claydite is as follows.
Сухую глину измельчают и шаровой мельнице до тонкости помола, соответствуюн1,его проходу порошка через сито 900 отв/см, а затем формуют гранулы на тарельчатом гранул торе , куда подают эмульсионную органическую добавку в виде эмульсии мазута в воде состава, часть: 1 мазута и 6 воды или органожелезистую эмульсосуспензию состава, часть: 1 мазута, 1 окислов железа и 6 воды.Dry clay is crushed and a ball mill to the fineness of grinding, corresponding to its passage of powder through a sieve of 900 holes / cm, and then granules are formed on a plate granulator, which is supplied with an emulsion organic additive in the form of fuel oil emulsion in water, part: 1 fuel oil and 6 water or organic iron emulsification of the composition, part: 1 fuel oil, 1 iron oxide and 6 water.
Отформованные гранулы подсушивают, а затем обжигают во вращающейс печи при 1150°С по фракци м.The formed granules are dried and then calcined in a rotary kiln at 1150 ° C in fraction.
Введение эмульсионных органических добавок в процессе гранулировани сухого порошкообразного глинистого сырь обеспечивает перераспределение органической добавки по сечению гранул с большей концентрацией последней во внутренней их части, что усиливает ее действие, поскольку окислителыю-восстановительнуе процессы сдвигаютс в сторону более высоких темнератур, а суха обработка глинистого сырь до порошкообразного состо ни позвол ет получить гомогенную массу.The introduction of emulsion organic additives in the process of granulating dry powdered clay raw material provides a redistribution of organic additives over the cross section of granules with a higher concentration of the latter in their internal part, which enhances its action, since the oxidative-reduction processes shift to higher temperatures, and dry processing of clay raw materials the powder state allows to obtain a homogeneous mass.
