KR100358400B1 - Production method of ocher small component (黃土 燒成 粉 生産 方法) - Google Patents

Abstract

The present invention relates to a method for producing ocher small components obtained by calcining ocher fine particles.

To this end, the present invention is made by dissolving the filtrate in water, precipitating and sedimenting it, and then collecting pure yellow soil to make fine particles by freeze-drying, and continuously throwing a certain amount into the firing furnace. It is the production method of ocher component which is calcined and recovered from stack.

Description

Production Method of Small Loess Components {.}

The present invention is a product that can be used as a substitute for stone powder, the fact that no ocher component is present in the production company, the pollution fine powder of the dust noise generated during the production of stone powder with enormous power loss in the grinding process and also stone powder There is a problem that can not express a variety of natural colors.

The present invention has been made to solve all the problems that occur in the production of stone powder as a product that can be used to replace the powdered dust firstly freezing the precipitated pure yellow soil and then ventilated drying to shrink and separate the expanded yellow soil during freezing It becomes particulate loess.

Second, a small amount of loess is scattered into the firing furnace continuously and scattered, and small components are recovered by a centrifugal force collector from the stack.

The third ocher powder changes color depending on the firing temperature and iron content. The addition of iron oxide powder to the yellow soil powder and the control of the firing temperature can produce various natural colors.

The method of manufacturing ocher powder is to put ocher in water, stir and put the suspension ocher in a filter and filter, leaving sandstone and miscellaneous material in the filter and suspending filtered ocher. One water is stored in the settler for precipitation. When completely precipitated, pure yellow soil accumulates in the lower part and dualizes into clear water in the upper part. The clear water in the upper part is discarded, and the pure yellow soil accumulated in the lower part is dried cotton cloth once more to remove moisture and then 30m / m Calcined × length 300Mm / m Pieces are made into individual pieces in the freezer and frozen. After complete freezing, if the individual is ventilated in a dryer, the expanded yellow soil during freezing is reduced and separated into a fine powder during drying.

In the method of preparing the small components, uniformly scattering a certain amount of the ocher powder made of fine particle powder into the firing furnace having an internal temperature of 1,000 degrees Celsius, the ocher powder is calcined by the internal heat, and the stack of To go out.

The small component is recovered from the stack by a centrifugal force collector. In addition, ocher powder changes color depending on the firing temperature and the iron oxide content. By controlling the iron oxide content and the firing temperature, various natural colors can be expressed.

As a substitute for stone powder, stone powder is discolored due to the use of chemical dyes.

However, since the ocher component is a natural color like porcelain color, the color does not change in any case. In addition, there is an effect that can be produced by a simple production method compared to the production process of stone powder.
