针对王坡矿选煤厂原加介系统存在的密度调节时间过长、加介不及时、介耗高等问题,在分析现场常用加介方式的基础上,结合王坡矿选煤厂现有的工艺系统、设备布置、空间结构,提出了将预先配比好的浓介直接加入到介质循环系统中的加介系统改造方案。改造后王坡矿选煤厂系统运转良好,大大缩短了介质系统密度的调节时间,提高了加介效率和灵敏度,同时还降低了介耗,有效控制了加介过程中系统跑煤与回收率低等问题,减轻了加介工的劳动强度。
In view of the problems of density adjustment of the original charging system in Wangpo Coal Preparation Plant, such as the excessive time for density adjustment, improper charging and high medium consumption, and on the basis of analyzing the commonly used charging methods at the site, Process system, equipment arrangement and space structure, a proposal of adding system to medium circulation system is put forward, which adds the pre-proportioned thick medium directly into the medium circulation system. After the transformation, the system of Wangpo Coal Preparation Plant runs well, greatly reducing the adjustment time of medium system density, improving the medium efficiency and sensitivity, reducing the medium consumption and effectively controlling the system running coal and recovery rates Low-level issues, reducing the labor intensity of additional workers.
