Jiangxi Nanchang filling industrial pump accessories, industrial filling pump accessories, and tailings paste filling pump accessories have caused serious pollution Establishing reliable filling industrial pumps and industrial filling pumps for paste filling systems can ensure the needs of underground filling industrial pumps and industrial filling pumps for paste filling, thereby reducing loss and impoverishment rates, improving mining safety, reducing tailings discharge, extending the service life of tailings ponds, and protecting the surface environment This article focuses on the actual situation of Susong phosphate mine and conducts key technical research on paste filling technology with high concentration graded tailings filling industrial pumps and industrial filling pumps as the core Based on on-site investigation and indoor testing, using fluid mechanics theory, mathematical methods, and fluid simulation software as the main means, a comprehensive and in-depth study was conducted on the paste filling ratio parameters of the graded tailings filling industrial pump and industrial filling pump of Susong phosphate mine, the paste filling methods and capabilities of the filling industrial pump and industrial filling pump, the paste filling station site of the filling industrial pump and industrial filling pump, the slurry preparation and transportation system scheme, the dewatering and settling effects of the horizontal sand silo, and the reliability of the pipeline self flow transportation system The main research results and conclusions completed are as follows: (1) The physical and chemical properties of whole tailings and graded tailings were analyzed. Through indoor proportioning experiments, graded tailings were selected as the filling industrial pump and industrial filling pump for paste filling aggregates. Ordinary 32.5 silicate water mud was used as the cementitious material, with a cement sand ratio of 1:4 and a slurry mass concentration of 72% Through flow performance testing, it is determined that the recommended ratio of slurry has good conveying performance. The slurry filling industrial pump and industrial filling pump are used for paste filling preparation station automatic control system, which involves an automatic control system. The monitoring computer is connected to an uninterruptible power supply, a report printer, and a lower level PLC controller. The 1st and 2nd pins of the lower level PLC controller are connected to the first and second distribution units, respectively.
