为了确保充填工艺的质量,研究对尾砂胶结充填系统的检测与控制是十分必要的。例如充填体的强度取决于水泥和尾砂量的配比及其浓度。一般说来,水泥用量增加而充填体的强度也增大,但超过合理的配比就会造成浪费。水泥砂浆浓度低了,在沉降时易出现离析和分层;浓度过高又将导致输送困难。因此,对物料用量进行自动检测,对其配比和浓度进行自动控制,是完善和提高充填系统生产能力的重要措施。近来冶金部矿冶研究所研制了“流态化吸出式砂仓”,经过工业试验表明,这种结构的砂仓卸料流量
In order to ensure the quality of the filling process, it is necessary to study the detection and control of the tailings cementation and filling system. For example, the strength of the filler depends on the ratio of cement and tailings and its concentration. In general, the amount of cement used to increase the strength of the filler body also increased, but more than a reasonable ratio will result in waste. Cement mortar concentration is low, prone to segregation and delamination when settling; too high concentration will lead to difficult delivery. Therefore, the automatic detection of the amount of material used, and its automatic control of the ratio and concentration, is an important measure to improve and enhance the production capacity of filling system. Recently Metallurgical Institute of Mining and Metallurgy developed a “fluidized aspiration silos”, after industrial tests show that this structure of the silo discharge discharge
