頼るしかなく、埋立てを容易にするための前処理として
焼却、分解、結合などの操作を施してきた。Conventional waste countermeasures are limited to the recycling of some metals, waste paper, and glass, and most of them ultimately have to rely on primitive landfill methods, with the aim of making landfill easier. Treatments include incineration, decomposition, and combination.

立てによる将来の環境におよぼす副次的影響、埋立てに
費す多額の経費等の多くの問題が山積している。However, these waste disposal methods are fraught with many problems, such as limited landfill space, the side effects of landfilling on the future environment, and the large amount of expense spent on landfilling.
以上の状況から、廃棄物の再資源化は今時の最大の課題
である。Given the above circumstances, waste recycling is the biggest issue of our time.
但し、廃棄物の処理や再資源化に際して十分留意しなけ

ことなどである。However, when processing and recycling waste, it is necessary to pay close attention to the fact that there is no risk of secondary environmental pollution occurring during processing and recycling, and that recycled products are of high quality. These include the fact that recycled products are superior in quality, their product costs are low, and users can fully understand and use recycled products.
この発明は、以上の条件を十分満たすことのできる廃棄
物の再資源化を目的とした。This invention aims at recycling waste that fully satisfies the above conditions.
この発明を実施した実施例を図にもとづいて説明すると
次の通りである。An embodiment of the present invention will be described below based on the drawings.
焼却炉から排出した焼却灰を図Ａ，Ｂの工程によって篩
別し、Ｍｅｓｈｅｓ６０以下の微細粉を水洗し未燃物等
の不純物を除去して、精製微細粉灰とする。The incinerated ash discharged from the incinerator is sieved through the steps shown in Figures A and B, and the fine powder with a mesh size of 60 or less is washed with water to remove impurities such as unburned materials, resulting in purified fine powder ash.
また、陶石、ＳｉＯ２，Ｋ２Ｏ・Ａｌ２Ｏ３・６ＳｉＯ
２，Ｎａ２Ｏ・Ａｌ２Ｏ３・６ＳｉＯ２，Ａｌ２Ｏ３・

2, Na2O・Al2O3・6SiO2, Al2O3・
2SiO2・2H2O, Al2O3・4SiO2・H2
O is crushed after removing impurities and washing with water. Next, in the step shown in Figure C, the mixture is sent to a ball mill and pulverized for 20 to 24 hours. Thereafter, purified fine ash and plastic clay are added, and the mixture is ground and mixed for 3 to 5 hours to form a slurry.
ボールミルから取出した泥漿は、図Ｄ，Ｅ，Ｆ，Ｇの工
程順序に従って篩別（Ｍｅｓｈｅｓ６０以下）し、水簸
したのち電磁選により脱鉄をおこなう。The slurry taken out from the ball mill is sieved (Meshes 60 or less) according to the process order shown in Figures D, E, F, and G, and after elutriation, iron is removed by electromagnetic separation.
次にフィルタープレスに送り脱水してケーキを得る。Next, it is sent to a filter press and dehydrated to obtain a cake.
ケーキは、真空土練機を通して混練と脱気とをおこなっ
て坏土とした。The cake was kneaded and degassed through a vacuum kneading machine to form clay.
坏土の組成によって焼成温度を異にし、適応製品も異に
するので、坏土の混合組成実用例を表１に示した。Since the firing temperature and applicable products are different depending on the composition of the clay, Table 1 shows practical examples of mixed compositions of the clay.
成型は、６０ｋｇ／ｃｍ２以上でプレス成型し、室温で
乾燥する。室温２５℃であれば１２０時間で水分は完全
に除去できる。The molding is performed by press molding at 60 kg/cm2 or more and dried at room temperature. At room temperature of 25°C, moisture can be completely removed in 120 hours.
十分乾燥したのち、焼成炉に送り焼成する。After it is sufficiently dried, it is sent to a kiln and fired.
焼成は１時間１５０℃前後の温度上昇速度が適当であり
、焼成結合温度に達したら火を止め、徐々に冷却して製
品を獲得する。A temperature increase rate of around 150° C. for 1 hour is suitable for firing, and when the firing bonding temperature is reached, the fire is stopped and the product is obtained by gradually cooling.
