The factors affecting the effect of heavy medium selection are mainly the nature of the suspension. In particular, the density, viscosity and stability of the suspension. The density of the suspension increases with the increase of the volume concentration of the suspended matter. When the volume concentration increases, the viscosity of the suspension also increases, which will increase the movement resistance of the ore particles, thereby making the sorting accuracy. And equipment production efficiency is reduced. Into the mineral crystal size more hours, the suspension should lower the viscosity required, to facilitate the mineral particles sorted quickly and accurately. Therefore, the concentration of the suspension should have a suitable range.
It is also important to maintain the stability of the suspension. Because stability is the key to keeping its density constant. When the pre-suspension particles are subjected to their own gravity, sedimentation will occur to change the density of the suspension, the upper layer becomes smaller, and the lower layer becomes larger, which affects the normal progress of the selection process. In order to prevent the sedimentation of suspended solids during production, mechanical agitation, vibration, and the use of rising or horizontal water flow and the addition of suitable stabilizers are often used.6040 CO2 Laser Engraving Machine
