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. Stainless steel Electrical And Electronic Instruments refer to stainless steel accessories on hand dryer stainless steel shell, electronic instrument shell, stainless steel buttery cover and accessroies, safety instruments stainless steel components, they are widely used in many fields. The common characteristic is that they are made by high quality stainless steel material and a compound mould, this compound mould have several parts such as a shearing die, a punching die, a deep drawing die, blanding die and so on.
