Изобретение относитс  к области производства строительных материалов.The invention relates to the production of building materials.

Известен способ получени  декоративного вермикулита серебристого цвета путем измельчени  вермикулитового сырь  до фракции 0,5-5 мм и обжига при температуре 600- 1000°С в восстановительной среде. Однако обеспечение устойчивой восстановительной среды ВНОСИТ осложнени  в технологию обжига и в результате практически трудно получить вермикулит равномерного серебристого цвета. Цель изобретени  - упрощение процесса обжига и улучшение качества вермикулита.A known method of obtaining decorative silver vermiculite is by grinding vermiculite raw materials to a fraction of 0.5-5 mm and calcining at a temperature of 600-1000 ° C in a reducing environment. However, the provision of a sustainable reducing environment VNOSIT complications in the firing technology and, as a result, it is practically difficult to obtain a uniform silver colored vermiculite. The purpose of the invention is to simplify the burning process and improve the quality of vermiculite.

Достигаетс  это тем, что вермикулитовое сырье измельчают до получени  чешуек диаметром 0,075-5 мм, толщиной 0,002-0,4 мм, а обжиг ведут в закрытых формах.This is achieved by the fact that vermiculite raw materials are crushed to obtain flakes with a diameter of 0.075-5 mm, thickness of 0.002-0.4 mm, and firing is carried out in closed forms.

Вермикулитовое сырье измельчают в дезинтеграторе при линейных скорост х вращени  ротора 30-60 м/сек до образовани  плоских чещуек условным диаметром 0,075-5 мм, толщиной 0,002-0,4 мм.Vermiculite raw materials are crushed in a disintegrator at linear rotor speeds of 30-60 m / s to form flat slabs with a nominal diameter of 0.075-5 mm, thickness of 0.002-0.4 mm.

Подготовленное таким образом вермикулитовое сырье засыпают в формы, например в металлические кокили, закрывают и направл ют на обжиг.The vermiculite raw material prepared in this way is poured into molds, for example, into metal chill molds, closed and sent for firing.

Закрытые металлические формы с вермикулитом прот гивают на конвейере через печное пространство, где поддерживаетс  температура 600-1000°С.The closed metal forms with vermiculite are pulled on the conveyor through the furnace space, where the temperature is maintained at 600-1000 ° C.

Обжиг вермикулита в плотно-насыпном состо нии в виде чещуек диаметром 0,075- 5 мм, толщиной 0,002-0.4 мм в закрытых формах обеспечивает получение декоративного вермикулита равномерного серебристого цвета с отрал ательной способностью до 90%, Это происходит вследствие того, что чешуйки указанных размеров почти не обладают свойством вспучиватьс  и их естественна  плотна  упаковка в формах затрудн ет диффузию кислорода в слой материала.The firing of vermiculite in a dense bulk state in the form of stones with a diameter of 0.075-5 mm, a thickness of 0.002-0.4 mm in closed forms provides for obtaining decorative vermiculite of uniform silver color with a reflecting ability of up to 90%. This is due to the fact that flakes of these sizes are almost do not have the property to swell and their natural tight packing in forms makes it difficult for oxygen to diffuse into the material layer.
