Practice of reducing consumption,cutting coarse and improving quality in Tangkou Coal Preparation Plant
Tang kou Coal Preparation Plant aims to solve problems such as high medium consumption,coarse flotation tailings,and poor desliming and dewatering effects.The existing coarse slime recovery system is reconstructed,and the orignal FX350-GJT∗8 small diameter slime water hydrocyclone group+HS-Z-242060 vibrating arc screen+H1-36-18 high-frequency screen coarse slime recovery system is transformed into FX500∗4 large diameter slime water hydrocyclone group+ZKJ2430 clean slime dual channel fine screen+ZKJ2030 middling coal slime dual channel fine screen process.By comparing the data of flotation tailings,coal slurry heavy medium magnetic separation tailings with medium,etc.,the modified process effectively solved the problems of coarse run and high medium consumption in the original system.The yield of coarse and fine coal slurry and flotation clean coal has significantly improved,increasing the comprehensive economic benefits of the site.
