The invention discloses a method for firing light ceramsite by using casting resin waste sand, and belongs to the technical field of chemical product preparation. The method comprises the following steps: obtaining the casting resin waste sand, treating the casting resin waste sand, and carrying out magnetic separation treatment on the casting resin waste sand, pouring the casting resin waste sand, dewatered sludge and clay into a mixer, uniformly stirring, mixing into mud, extruding and granulating, drying and preheating the extruded light ceramsite semi-finished product, roasting the light ceramsite semi-finished product at high temperature, and finally cooling. Mineral salt, copper slag, red mud, coal gangue and mixtures of the mineral salt, the copper slag, the red mud and the coal gangue can be further added into the mixtures of the casting resin waste sand, the dewatered sludge and the clay, the mineral salt can increase the overall mineral content of the materials, and meanwhilethe waste utilization rate of the copper slag, the red mud and the coal gangue can be increased. Proportioning and adding are carried out according to different principles, the light ceramsite with different qualities can be obtained, and the preparation direction is relatively simple and efficient.
本发明公开了一种利用铸造树脂废砂烧制轻质陶粒的方法，属于化工产品制备技术领域，其中先获取铸造树脂废砂，然后对铸造树脂废砂进行处理，然后将铸造树脂废砂进行磁选处理，然后将铸造树脂废砂、脱水污泥与粘土倒入混合机中搅拌均匀并混炼成泥，然后挤压造粒，接着对挤压后的轻质陶粒半成品进行干燥与预热，然后对轻质陶粒半成品进行高温焙烧，最后进行冷却。在铸造树脂废砂、脱水污泥与粘土的混合物中还可以加入矿物盐、铜渣、赤泥、煤矸石以及它们的混合物，其中矿物盐可以增加物料的整体矿物质含量，同时可以提高铜渣、赤泥、煤矸石的废物利用率，通过不同的原理配比与添加，可以得出不同品质的轻质陶粒，同时制备方向相对简单高效。
