How are free settlement, interference settlement, equal drop granules and equal drop ratio defined?
The individual settlement of a single ore in a broad medium space is called free settlement, and the settlement of individual ore particles in the group is called interference settlement. In the process of free sedimentation, the ore particles are only affected by their own gravity, medium buoyancy and resistance and are not affected by other factors. In the process of interference sedimentation, in addition to its own gravity, medium buoyancy and resistance, individual ore particles will also be affected by friction, collision and suspension of other ore particles, thus changing the sedimentation velocity and movement of individual ore particles. Track. It can be seen that the interference settlement process is much more complicated than the free settlement. All settlements in the re-election practice are interference settlement, but when the distance between the particles in the grain group is large, that is, the volume concentration ( the ratio of the total volume occupied by the ore particles to the total volume of the suspension ) is small ( generally less than 3). %) , the interference between the ore particles becomes very weak, which can be regarded as free sedimentation.
In free settling, the sedimentation velocity of the ore particles is related to the density, particle size and shape of the particles. When settled in the same medium, particles of different density, particle size and shape may have the same settling velocity at specific conditions, and these different particles having the same settling velocity are called equal-falling particles. Obviously, there are small particles of small density ( having a particle size of d 1 ) and small particles of large density ( set to d 2 ) , and the ratio of d 1 to d 2 is called an equal reduction ratio.Stainless Steel Welded Wire Mesh
