Description

Technical Field

[0001] The invention relates to the technical field of crushing devices, and in particular to a petroleum coke crushing device and method for prebaked anodes. Background Art

[0002] Prebaked anodes are mainly used in the aluminum electrolysis industry and are key materials in the aluminum electrolysis process. Prebaked anodes are usually made of petroleum coke and a binder (such as asphalt) and have good electrical conductivity and chemical stability. Among them, petroleum coke is a solid carbon material produced in the oil refining process, mainly derived from the distillation and cracking of heavy oil. This material contains a high proportion of carbon and low volatile matter, has excellent electrical conductivity and chemical stability, and is very suitable for aluminum electrolysis anodes. Due to the large volume of petroleum coke, when using petroleum coke to process prebaked anodes, the petroleum coke needs to be crushed into particles of appropriate mesh size. However, when existing petroleum coke crushing devices crush the petroleum coke, they mostly directly put the petroleum coke into the crushing equipment for multiple crushing. However, some impurities will adhere to the surface of the petroleum coke. If it is directly crushed, the surface impurities will be mixed in the crushed petroleum coke, and separate screening will be required later. Since the impurities are mixed in the crushed petroleum coke, the processing efficiency is relatively slow, which affects the overall processing efficiency of the petroleum coke.
