Lightweight and high-strength ceramsite, preparation method and application thereof
The invention relates to a lightweight and high-strength ceramsite, a preparation method and application thereof. The preparation method of the lightweight and high-strength ceramsite comprises the following steps of: (1) mixing stone coal sodium salt roasting vanadium extraction tailings with an aluminum-containing auxiliary material to obtain a mixed material; and (2) granulating and roasting the mixed material obtained in the step (1) to obtain the lightweight and high-strength ceramsite. The method takes the stone coal sodium salt roasting vanadium extraction tailings as the raw material,adds wastes such as fly ash, red mud and aluminum ash as auxiliary materials, carries out mixing, pelletizing, drying, roasting, cooling and the other steps, and controls the ratio of the raw materials to the auxiliary materials and roasting process parameters, realizes effective immobilization of alkali metal in the stone coal sodium salt roasting vanadium extraction tailings, prepares the lightweight and high-strength ceramsite with low stacking density, high cylinder pressure strength and low water absorption, and realizes harmlessness and recycling of various industrial waste materials.
本发明涉及一种轻质高强陶粒及其制备方法和用途。所述轻质高强陶粒的制备方法包括如下步骤：(1)将石煤钠化焙烧提钒尾渣和含铝辅料混合，得到混合材料；(2)将步骤(1)所述混合材料进行造粒，焙烧，得到轻质高强陶粒。本发明以石煤钠化焙烧提钒尾渣为原料，添加粉煤灰、赤泥、铝灰等废弃物作为辅料，经过混料、造球、干燥、焙烧、冷却等步骤，通过控制原辅料配比和焙烧工艺参数，实现石煤钠化焙烧提钒尾渣中碱金属的有效固定并制备出具有堆积密度低、筒压强度高、吸水率低的轻质高强陶粒，实现多种工业废料的无害化和资源化。
