白羊岭选煤厂降低介耗的措施

针对白羊岭选煤厂介耗偏高的问题，通过在脱泥筛筛面新增一段喷水，加大脱泥力度，降低介质系统煤泥量；调整喷水高度、喷嘴安装角度，后移喷水管道，增加喷嘴，提高喷水脱介效果；增设篦子，定期清理、更换筛板，合理调整磁选机底流孔开度，提高磁铁矿回收率；自制煤泥水处理药剂添加装置，灵活控制调节加药量，保证洗水水质；改善介质粉仓储环境，减少介质粉管理流失；组织实施“跑冒滴漏”专项治理活动，加强介质管理，减少介质消耗。改造后，选煤厂介耗由原来的1．20kg／t降至目前的0．50kg／t，仅磁铁矿消耗一项每年可节约成本168万余元，经济效益显著；有效改善生产现场作业环境，提高选煤厂质量标准化管理水平，为建设安全、高效现代化矿井奠定基础。

Medium consumption reduction measures in Baiyangling coal preparation plant

To reduce the medium consumption in 8aiyangling coal preparation plant, the desliming sieve add a spray of water to improve desliming performance and reduce slime content of medium system. Adjust the spray height and nozzle angle, move backward the spray pipe, add nozzle, regular clean and replace sieve plate, adjust the underflow opening angle of magnetic separator to improve the magnetite recovery, control dosage by slime water treatment medicament adding device, which is made in Baiyangling coal preparation plant, reinforce medium management and improve its storage conditions, govern the slime water leakage. After transformation, the medium consumption decrease from 1.20 kg/t to 0. 50 kg/t,the magnetite power savings per year is worth about 1.68x106 yuan. Improve the production conditions and quality standard management, lay the foundation for the construction of safety, high efficiency of modern coal mine.
