电解铝生产过程中，熔炼炉内要加入一些除渣剂，耙渣过程中或多或少夹带部分微细的铝颗粒。将其从渣中分离出加以回收，既能创造经济效益又能保护环境。下面介绍一种回收铝用的简易压渣装置。１．工作原理铝在７００～１２００℃时呈液态且流动性好，因此，设计压渣机时要考虑 Electrolytic aluminum production process, the melting furnace to add some slag removal agent, rake slag more or less entrainment part of the fine aluminum particles. Separated from the slag to be recycled, both to create economic benefits and to protect the environment. The following describes a simple recovery of aluminum with a slag device. 1. Working principle Aluminum at 700 ~ 1200 ℃ was liquid and good fluidity, therefore, the design of slag pressing machine to consider when
