本発明は電気集！！ｉ！機等により回収された石炭灰を
原料として天然石の代わりに用いられる人工骨材を製造
する方法に関する。[Detailed Description of the Invention] The present invention is an electric collector! ! i! The present invention relates to a method for manufacturing artificial aggregate that can be used in place of natural stone using coal ash recovered by a machine or the like as a raw material.

ある。When manufacturing artificial aggregate, it is necessary to provide a certain degree of strength depending on the intended use (application) of the manufactured artificial aggregate. However, conventional artificial aggregates that only use water as a binder may not have sufficient strength depending on the properties of the coal ash, and may not be usable depending on the purpose.

造することができる。Therefore, the present invention provides a method for producing artificial aggregate that solves these problems, and its features are as follows:
Coal ash is put into a granulator, and water glass diluted with water is sprayed onto the coal ash to granulate it, and the raw pellets released from the granulator are mixed to form artificial aggregate. According to this manufacturing method, since water glass is used as a binder, an artificial bone material with greater strength than the conventional 1:t artificial bone structure using only water as a binder can be manufactured. can do.
以下、本発明の一実施例を図にツ１：づいて説明する。An embodiment of the present invention will be described below with reference to the drawings.

Spraying: (for example, the weight ratio is about 15 mm of diluted water glass to about 85 mm of wet coal ash.6~15 mm)
Granulate into man-green pellets. Next, the raw pellets discharged from the granulator (4) are supplied to a calciner (6) and calcined. In the firing process, drying, firing, and cooling are performed sequentially and continuously. The artificial aggregate thus produced is separated into finished pellets and defective pellets using a sieving force of 02 (7).

Measured according to S standard M-8718F method for measuring crushing strength of iron ores (pellets). As is clear from FIG. 2, when comparing the room temperature crushing strength of artificial aggregates at the same firing temperature, the water glass-added artificial aggregates are stronger, especially ioo.
