(1) The disposal of waste slag and sand from casting factories can be processed by grinding machines to become renewable building and composite materials, and landfill is also a commonly used treatment method.
(2) The wastewater from the treatment of foundry waste can be precipitated, and the precipitate can be dried and ground into powder, becoming the raw material for concrete;
(3) The treatment of molten iron slag in the waste slag of a foundry is mainly through deep processing by a grinding machine, used for road building materials, or buried with inert materials.
(4) The waste slag from the foundry and the furnace lining from the pouring ladle can be processed into fine powder below 325 mesh using a grinder as secondary raw materials for cement and brick factories.
(5) Of course, by directly collecting relatively fine dust from casting equipment, we can directly apply it to materials such as recycling in melting furnaces, cement fillers, and concrete.
