Basic description: Overhaul slag is a collective term for overhaul cell liners and overhaul cathode carbon blocks, mainly composed of solid waste materials from the lining of aluminum electrolysis cells replaced at the end of the life cycle of overhaul. Its main hazard is the excess of soluble fluoride and cyanide, which has been clearly listed as hazardous waste and must be treated harmlessly.

Product overview Technical advantages Functional characteristics

    Fluoride fixation and cyanide removal are carried out through innovative processes,and the process water is recycled and not discharged. The environmentally friendly solid materials are made into no-burn bricks after batching, molding and maintenance. There is no "three wastes" and other hazardous substances in the production process, which is environmentally friendly and economical.

It adopts the continuous method of fluoride and cyanide removal and continuous filtration process, with a high degree of system automation.

The crushing system is specially designed for waste cathode materials, and the crushing effect is better.

The process flow is short, the equipment layout is compact, and the floor area is small.



Only two agents are used in the non-hazardous treatment system and all agents used are cheap and readily available.


The material after solid-liquid separation treatment has a low water content of about 15%, and the equipment does not use acid for maintenance.

Safety measures are added in the production process to solve the safety hazards such as flammable and explosive reactions.
