How to deal with the waste residue of the foundry?

The disposal of foundry waste has always been a matter of great concern to the government, especially in recent years, China has put forward the requirement of "realizing sustainable development and building a resource-saving and environment-friendly society". In the stage of industrial development, the importance of foundry is particularly prominent. What are the main waste residues of foundry? What are the main methods to treat the waste residue of foundry? What equipment is needed to deal with the waste residue of the foundry?

What does foundry waste residue mainly contain?

Generally speaking, the treatment of foundry waste residue is mainly aimed at the treatment of solid and liquid waste residue. Because the waste slag produced by different foundries is different, here we mainly discuss the treatment of solid waste in the waste slag of foundries.

The waste slag of foundry generally contains pig iron, scrap steel, waste machine iron, spheroidizing agent, vermiculating agent, ferrosilicon, carburizing agent, sulfur increasing agent, inoculant, chromium, manganese, molybdenum, copper, etc. Auxiliary materials include sand, pulverized coal, clay, Pengrun soil, resin, etc. the types of waste slag produced by different foundries are different. Therefore, we should treat the waste slag of the foundry according to the different types of waste and miscellaneous in detail.

Scheme for treating waste slag from foundry

Referring to the waste treatment methods of foreign foundry enterprises, there are several aspects to deal with the waste residue of foundry：

　　（1）The waste slag and sand from foundry can be processed by grinding machine and become renewable building materials and composite materials. Landfill is also a common treatment method.

　　（2）The waste water in the waste residue of the foundry can be treated and precipitated. After drying, the precipitate can be ground into powder and become the raw material of concrete；

　　（3）The treatment of molten iron slag in the waste slag of the foundry is mainly the deep processing of the pulverizer for the use of road building materials or the buried of inert materials.

　　（4）For the treatment of the waste furnace lining in the waste slag of the foundry and the waste lining in the pouring ladle, the fine powder with the waste slag below 325 mesh can be processed by the pulverizer as the secondary raw material of the cement plant and brick factory.

　　（5）Directly collect fine dust in casting equipment, which can be directly applied to recycling in melting furnace, cement filler, concrete and other materials.

What equipment is needed to treat the waste residue of the foundry　　In the process of recycling, the most common and common way is to add a pulverizer production line for solid waste treatment. So what kind of milling equipment should be used? How about the cost? I believe many enterprises are paying attention to this problem.

　　HC Series Raymond Mill
