| Description | During metallurgical mining, most of the mined material is of no use for the industry. Only a very small portion can be used to receive the desired precious metals. The waste material is called tailings and must be transported to surface dams or mixed with additives to become a backfill paste which is transported back to the stopes. Hydraulic driven Piston pumps are one solution to deliver this high volume over long distances in a safe and economical way. However, the design principle of a hydraulically driven piston pump leads to pulsation in a delivery pipeline which is caused by the fact that the general design is based on a discontinuous working principle. The pumps are pumping one cylinder after another into the transportation pipeline. This results on one hand in flow fluctuations and consequently in pressure losses. For optimal performance of the system it is recommended to use a pulsation dampening system with the Piston Pump. The reason is to create an approximately continuous flow of the material which is preventing pressure peaks resulting from water-based high-density solids (so-called Water Hammer Effect) with a low air content being pumped at great speed against a high pressure. Furthermore, the limited variances in flow and pressure are resulting in lower forces inside the pipeline system which leads to lower operating costs and a safer working environment for the employees on the mine site. This paper identifies and describes the major three innovations and their different working principles of Pulsation Dampening of Paste- and Slurry Systems and discusses their application in Detail. First System is the use of a hydraulic driven Seat valve pump with continuous Flow system. Second possibility is the use of piston pumps with hydraulic driven Pulsation Dampening System and finally, the use of Ventilated Pulsation Dampening Systems. The job site reports show how the dampening systems are implemented at various job sites. Book Name: Minefill 2020-2021 |
