Treatment method of iron and steel smelting dust mud and iron correction material
The invention discloses a treatment method of iron and steel smelting dust mud and an iron correction material. The treatment method of the iron and steel smelting dust mud comprises the following steps that S1, dust premixing is conducted, specifically, feeding low-grade dust and high-grade dust into a premixing system to be evenly mixed, and forming the mixed dust; S2, mud cake pre-crushing andmixing: feeding the low-grade mud cake and the high-grade mud cake into a pre-crushing system for crushing and mixing to obtain a mud cake mixture; s3, strong mixing granulation: sending the mixture of the mixed dust and the mud cake into a strong mixing granulation system, and fully mixing to prepare mixed particles; sending the mixed particles into a stockpiling area, and stockpiling for 1-3 days to form an iron correction material. According to the treatment method of the iron and steel smelting dust mud and the iron correction material, the problem that mud cakes generated by low-grade dust and sewage environment treatment are difficult to treat is solved, resource utilization of the iron and steel smelting dust mud is achieved, and good economic and environmental benefits are achieved.
本发明公开了一种钢铁冶炼尘泥的处理方法及铁质校正料，其中钢铁冶炼尘泥的处理方法，包括如下步骤：S1，粉尘预混，将低品位粉尘与高品位粉尘送入预混系统混合均匀，制得混合粉尘；S2，泥饼预碎混合，将低品位泥饼与高品位泥饼送入预碎系统进行破碎和混合，制得泥饼混合物物；S3，强力混合造粒，将混合粉尘与泥饼混合物送入强力混合造粒系统中充分混合，制得混合颗粒物；混合颗粒物送入堆存区，堆存1～3天后形成铁质校正料。本发明的一种钢铁冶炼尘泥的处理方法及铁质校正料，解决了低品味粉尘、污水环境治理产生的泥饼难以处置的问题，实现了钢铁冶炼尘泥的资源化利用，具有良好的经济和环境效益。
