由昆明有色冶金设计研究院设计选用的双滚筒式抓斗吊电子秤,在云南锡业公司大屯选厂、第三冶炼厂投入运行。该秤在设计时采用整体称重方式,具有称重精度高、性能稳定、小车在任何位置都可以进行称重等优点。云锡第三冶炼厂将抓斗吊用于原料配料,称量系统配有累加器。云锡大屯选厂抓斗吊用于铜精矿、硫精矿出厂时装火车、装汽车时的计量,称量系统配有大屏幕显示器及带累积功能的打印机。两台秤的精度均优于0.3％。采用抓斗吊电子秤不仅可以解决产品的出厂计量问题,还可以精确装车,既能充分发挥火车、汽车的运输潜力,又不使之超载,这方面的经济效益也是十分明显的。
Kunming Nonferrous Metallurgical Design and Research Institute of the design and selection of dual-drum grab crane electronic scales, in Yunnan Tin Company Datun election, third smelter into operation. The scale used in the design of the overall weighing method, with high precision weighing, stable performance, the car can be carried anywhere in the weighing and so on. Yun tin third smelter grasping hanging for raw material ingredients, weighing system with a totalizer. Yunxi Datun picking plant grab crane for copper concentrate, sulfur concentrate factory fashion train, when the car is equipped with metering, weighing system with a large screen display and printer with a cumulative function. The accuracy of both scales is better than 0.3%. The use of grab crane electronic scales not only solve the problem of factory product measurement, but also accurate loading, both to give full play to the potential of trains, cars, without overloading, in this area is also very obvious economic benefits.
