同忻选煤厂降低介耗的生产实践

摘要

In terms of technology and management, the causes of high media consumption were studied in Tongxin Coal Preparation Plant. The paper proposed some measures, including controlling quality of magnetite powder, strengthening work efficiency of medium draining screen and magnetic separator, setting wet de-shiming process, avoiding accidents such as moving, falling, dripping, leaking, and spilling, reducing accident rate and unnecessary discharge of materials and media. Through these improvement and transformation, the production of Tongxin Coal Preparation Plant goes smoothly with accident rate, media consumption, and cost decreasing significantly, which has achieved great economic and social benefits.%从技术和管理两方面对同忻选煤厂介耗偏高的原因进行分析并提出方案，包括控制磁铁矿粉的质量，强化脱介筛和磁选机工作效率，设置原煤湿法脱泥工艺环节，避免“跑、冒、滴、漏、撒”事件发生、降低事故率减少无谓排料排介等。通过以上环节的完善和改造，同忻选煤厂的生产日趋平稳，事故率大幅降低，介耗量显著减少，生产成本显著降低，取得了良好的经济效益和社会效益。
