Recycling method of casting waste and obtained roasted sand and porous ceramsite
The invention discloses a casting waste recycling method and obtained roasted sand and porous ceramsite, and the casting waste recycling method comprises the following steps: carrying out wet mixing on casting dust and waste chip liquid, and then granulating to form a granular green body; the granular green body and casting waste sand are put into a roasting furnace together to be roasted under the oxygen-enriched condition, the casting waste sand is converted into roasted sand, the granular green body is converted into porous ceramsite, and a roasted product is obtained; and screening and separating the roasted product to obtain the roasted sand and the porous ceramsite. According to the method, energy consumption can be reduced, environmental pollution and recycling are avoided, and the resource utilization rate is increased.
本发明公开了一种铸造废弃物的再利用方法及得到的焙烧砂和多孔陶粒，铸造废弃物的再利用方法，包括以下过程：将铸造粉尘和废切屑液进行湿混，然后造粒形成颗粒状坯体；将所述颗粒状坯体和铸造废砂一起投入焙烧炉在富氧条件下进行焙烧，所述铸造废砂转化为焙烧砂，所述颗粒状坯体转化为多孔陶粒，得到焙烧产物；将所述焙烧产物进行筛分分离，得到所述焙烧砂和所述多孔陶粒。本发明的方法能够节约能耗、避免污染环境以及回收再利用，提高资源利用率。
