哈尔乌素选煤厂三产品智能干选的可行性分析

Feasibility Analysis of Three-product TDS in Ha′erwusu Coal Preparation Plant

针对哈尔乌素选煤厂提质增效改造工程中,200~50 mm块原煤的中煤量大的特点,传统两产品智能干选难以获得理想效果,采用三产品智能干选技术分选200~50 mm的块原煤。通过对哈尔乌素的煤样进行分析试验,采用三产品智能干选技术,既可以保证精煤与矸石的发热量指标,又可以回收低质的中煤。

For implement quality efficiency makeover of Ha′erwusu CPP,the quantity of 200~50 mm raw middlings lump coal is massive,the traditional equipment of two-product TDS is difficult to obtain the ideal effect,so it adopts three-product TDS for 200~50 mm raw lump coal sepaiapion.By the analysis test of coal sample from Ha＇erwusu,it uses three-product TDS technology,not only ensure the calorific value index of clean coal and reject,but also recycle the middlings.
