| Abstract: | Introduce the problems existed in dense-medium separation system after Xinzhuang coal preparation plant transformation. Compare the advantages and disadvantages of two kinds of solutions. Based on existing technological characteristics, equipments layout, raw coal washability and transformation costs, adopt pre-desliming and non- pressurized feeding separating process. Analyse the separation density, recovery efficiency, medium in product, desliming effects, economic benefits after transformation. The results show that, the process increases profits more than 7.8× 106 yuan for the plant. The transformation provides reference for other coal preparation plants. |
