Method for firing light ceramsite by using metro spoil and machine-made sand tailing mud
The invention discloses a method for firing light ceramsite by using metro spoil and machine-made sand tailing mud, which solves the problem of environmental pollution caused by spoil such as metro spoil and machine-made sand tailing mud, and the prepared product is green and environment-friendly and has high added value. The production process comprises the following steps: 1, pretreating the metro spoil and the machine-made sand tailing mud; 2, drying the pretreated metro spoil and machine-made sand tailing mud; 3, mixing and preparing the dried metro spoil, machine-made sand tailing mud and an additive; 4, extruding the mixed material into a blank; and 5, sintering the ceramsite blank in a kiln. The lightweight ceramsite is fired by taking metro spoil and machine-made sand tailing mud as main raw materials. Environment pollution caused by the metro spoil and the machine-made sand tailing mud is overcome, resources are fully utilized, clay needed by traditional ceramsite preparation is replaced, land resources are effectively protected, and meanwhile the preparation cost is reduced. The fired light ceramsite has the characteristics of low water absorption, low density, high strength, good heat insulation effect and the like.
本发明公开一种利用地铁弃土与机制砂尾泥烧制轻质陶粒的方法，它解决了地铁弃土、机制砂尾泥等弃土引起的环境污染问题，制备的产品绿色环保、附加值高。其生产工艺如下：一、地铁弃土、机制砂尾泥的预处理;二、预处理后的地铁弃土、机制砂尾泥干燥处理；三、干燥后的地铁弃土、机制砂尾泥与添加剂的混合配制；四、混合后的物料挤压成胚；五、陶粒胚入窑烧结。本发明以地铁弃土、机制砂尾泥为主原料烧制轻质陶粒。不仅解决了地铁弃土和机制砂尾泥的环境污染，还实现了资源的充分利用，替代了传统陶粒制备所需的黏土，有效保护土地资源的同时降低了制备成本。所烧制的轻质陶粒具有吸水率低、密度小、强度高、隔热效果好等特点。
