塔山选煤厂进入调试阶段以来,随着第一、二、三套系统的运转,重介质系统的密度呈不稳定状态,时高时低,精煤的产率和灰分也极不稳定,介质消耗的量也越来越大,严重制约着选煤厂的正常生产。本文分析了改造前介质系统存在的问题,查找出原因,对系统进行改造,达到了降耗提效的作用 Tashan Coal Preparation Plant into the commissioning phase, with the first, second and third sets of system operation, the density of heavy media system was unstable, high and low time, the yield and ash of coal is also very unstable, medium The amount of consumption is also increasing, seriously restricting the normal production of coal preparation plant. This article analyzes the problems existing in the pre-reforming media system, finds out the reasons, rebuilds the system, and achieves the effect of reducing consumption and improving efficiency
