subject: Texture And Operation Ways Of Rotary Separator [print this page] Choosing a high-quality magnetic separator is very important. However, the magnetic separator also needs daily maintenance and regular inspection in the daily use to keep high performance and high production capacity. In terms of the regular inspection of the magnetic separator, we should pay attention to the followings.
Rotary separator is mainly made up of transmission system, grading device, feeding decentralized structure and cleaning device. Rotary separator is mainly applied in the Ore Beneficiation plant as the gravity classifying machine. Therefore, it is also called density separators and screw separator.
The Structure of Density Separators
The density separators can be composed of pulp distributer, newel, spiral chute and product interception unit and so on.
The Classifying Principle of Screw Separator
The pulp is fed into the spiral chute through distributer. During the motor process in which the mineral particle movesthe sedimentation rate of heavy mineral accelerates and heavy mineral sinks to the bottom of water flow. However, the light mineral floats in the upper layer of water flow. And then, the heavy mineral and light mineral expand along landscape orientation. The sunken heavy mineral moves towards the inner side along spiral line. The floating mineral moves towards the intermediate partial external area along spiral line. The mineral with different density moves along each gyration radius. However, the light mineral evenly ranks from the external side to the inner side. At last, the separation process is finished successfully.
The Advantages of Rotary Separator
Most screw graders can be widely applied in the separating working in coarse coal separating plants. Screw separation machine features high separation precision, small occupation area and large processing capability. In particular, because there is no moving parts itself, so medium and agentia can be saved. In addition, this kind of machine is favored by most producers due to its convenient operation, small maintenance amounts, low processing cost.dry and wet types rotary kiln: http://www.china-hxjq.com/n299.html
The Factors Affecting the sedimentation of Spiral Classifier
The working principle of spiral classifier is to depend on the theory that solid mineral with different size and proportion is different in the sedimentation rate in the liquid. We can see that the major factor affecting the classification efficiency of akinsclassifier is the sedimentation of mineral. There are two kinds of sedimentation in the medium, namely free sedimentation and hindered sedimentation. There are a lot of factors affecting the sedimentation in the process of mineral sedimentation, such as pulp density, buoyancy and so on.
Permanent drum magnetic separator is suitable for wet separation of the fine strongly-magnetic materials particles. Through the ore feeding box, the pulp enters into the tank, and then the pulp goes into the mineral feeding area in loose state. When in the magnetic field, under the effect of the magnetic field, the strongly-magnetic materials are absorbed on the surface of the cylinder. During the rotating process of the cylinder, the magnetic particles roll in chain-like. At the same time some gangue grain and sand mixed among the magnetic materials are washed out. Rotating with the cylinder, the magnetic materials are taken out of the mine area and crushed into the clean mine. While the non-magnetic materials are casted off, under the effect of the slurry flow in the trough body, discharged from the tailings port. Then the separation is over.
