Method for producing anti-seepage brick of aluminum electrolysis cell from waste electroceramic material
The invention relates to a method for producing an anti-seepage brick of an aluminum electrolysis cell from a waste electroceramic material, which comprises the following steps: 1) coarsely crushing the waste electroceramic material to below 50mm by a jaw crusher, crushing to below 10mm by a roll crusher, and finely crushing to below 2.8 mm by the roll crusher to obtain a waste electroceramic aggregate of less than or equal to 2.8 mm; (2) mixing and stirring the waste electroceramic aggregate, a binding agent and a component regulator to obtain pug, ageing the pug, then performing compression to obtain a green body, drying the green body, and then performing high-temperature firing to obtain the aluminum electrolysis cell anti-seepage brick, in the step (1), the materials obtained after intermediate crushing are screened and classified, coarse particles of 10-6 mm, medium particles of 6-3 mm and fine particles smaller than or equal to 3 mm are obtained, and the coarse particles, the medium particles and the fine particles are matched according to the proportion of 1: 1: (1-1.5) and then subjected to fine crushing. According to the method, the quality of the aggregate obtained after the waste electroceramics are crushed is controlled, and the appearance qualification rate of the green body can be increased to 96% or above.
本发明涉及一种废电瓷料生产铝电解槽防渗砖的方法，包括以下步骤：1)废电瓷料经过鄂式破碎机粗碎到50mm以下，再经过对辊破碎机中碎到10mm以下，再经过对辊破碎机细碎到2.8mm以下，得到≤2.8mm的废电瓷骨料；2)废电瓷骨料与结合剂、成分调整剂混合搅拌得到泥料，泥料进行困料处理，再进行压型得到生坯，生坯烘干后进行高温烧制，得到铝电解槽防渗砖；步骤1)中，中碎以后的物料进行筛分分级，得到10‑6mm的粗粒料、6‑3mm的中粒料和≤3mm的细粒料，将粗粒料、中粒料和细粒料按1：1：1‑1.5的比例配比后再进行细碎。本发明通过控制废电瓷料破碎后的骨料质量，可以将生坯外观合格率提高至96％以上。
