精煤储运系统给煤设备的技术改造

Technical Transformation of Coal Feeder in Storage and Transportation System for Clean Coal

西铭矿选煤厂精煤储运系统中,给煤设备是精煤外运时控制精煤出厂量的关键设备,目前采用的甲带给煤机存在易腐蚀、维护困难、成本高等问题,严重影响给煤效率,维修工人的劳动强度很大,要求进行大的技术改造。西铭矿选煤厂采用结构简单的给料溜槽代替了原来的甲带给煤机,取得了很好的效益。

In the storage and transportation system for clean coal in Coal Preparation Plant in Ximing Mine,coal feeder is the key to control clean coal production.Armored belt coal feeder has some weaknesses such as easy corrosion,difficult maintenance,and high cost,which have seriously impacted the coal feeding efficiency.In addition,it needs high labor intensity of maintenance workers and technical transformation.Feeding trough with simple structure was used to take place of armored belt coal feeder,which has achieved ideal benefits.
