The beneficiation process is finished by manganese beneficiation plant and consists of many different stages of crushing, grinding, size classification, washing, filtration, sorting, washing, separation and so forth.Manganese beneficiation operation aims to separate and concentrate the mineral values from waste material, remove impurities, or put together the ore for even further refinement. Beneficiation activities typically don't adjust the mineral values themselves besides by crushing and grinding, or enlarging particle size to facilitate processing.

In Brunei, the suppliers of machines for industrial ceramics are a lot, such as shanghai Zenith Company. These machines have high quality guarantee. It can offer all kinds of grinding mill machines, crushing machines, as well as some other beneficiation machines.

With the developing of global economy, construction industry is becoming more and hotter, sand and gravel aggregate become essential materials than necessary. SBM Company is one professional manufacturer of mining equipment not only in domestic area but also in oversea area. Its safety operating principle is very important for its service life time. As we know, the natural sand is limited; in order to protect the natural environmental, artificial sand becomes mainstream in the market, so the sand making machine is more and more welcomed by the customer for the whole production line. Here SBM most professional engineer will give you the excellent technical support about safety operating principle of sand making machine.

While the cobble which don’t meet the size requirement, will again enter into the cone crusher for crushing. After screening, the cobble which meet the size requirement, enter into VSI1140 sand making machine. Then, this cobble is transported to the vibrating screen by belt conveyor.After extrusion and crushing, through the belt conveyor, cobble is transported to the cone crusher for secondary crushing.

In addition, not only the impact force caused by the collision but also the shock wave caused by the cavity collapse can be maintained large over a long distance in the pipeline, and the amount of removal of corners and foreign matters can be further increased. Furthermore, the pressurized air that diffuses into the air more quickly than the wash water can be positioned inside the cavitation flow, and unlike the conventional pressure fluid mainly composed of the wash water, the ejected pressure fluid is Immediately after jetting, the sand for aggregate is carried to the inner wall of the pipe and collides violently while expanding greatly toward the inner wall of the pipe at a high speed, so the impact force and the frequency of collision with the inner wall of the pipe increase. In addition, the efficiency of removing corners and foreign matters can be further improved. ), And the shock wave generated by the cavity collapse in the cavitation flow acts greatly on the aggregate sand, and the removal efficiency of corners and foreign matters can be enhanced.That is, according to the first aspect , the aggregate sand transported in the primary processing apparatus is not a mere high-pressure washing water as in the prior art, but a jet including a large amount of cavities (hereinafter referred to as “cavitation flow”). Due to the force action, the aggregate sand can be separated from the pressure fluid and violently collide with the inner wall of the duct. In addition, the inner and outer surfaces of the cavitation flow can always be brought into contact with a large amount of air, from which a large amount of small bubbles are taken into the cavitation flow as cavities, or when these small bubbles do not collapse as cavities. Thermal damage due to impact can be greatly suppressed, the service life of the primary cleaning device can be reduced by extending the pipeline life. The frequency increases, and the efficiency of removing corners and foreign matters can be further improved.Since this invention was comprised as mentioned above, there exists an effect shown below. Furthermore, the aggregate sand receives an impact force due to the turbulent vortex generated by the spiral protrusion.According to the third aspect, even if the transfer speed of the aggregate sand by the pressure fluid from the injection nozzle decreases in the middle, the transfer speed is accelerated again by the pressure fluid from the auxiliary injection nozzle joining the pressure fluid. Even in such a case, since a large amount of air components serving as bubble nuclei of the cavity are dissolved in the washing water of the cavitation flow, the amount of the cavity of the cavitation flow is increased, and the generation of a shock wave when the cavity is collapsed can be promoted.According to claim 4, low-quality drainage after classification treatment can be reused for washing water without performing advanced water treatment, drastically reducing drainage treatment costs, and environmental conservation through a closed system. Can be promoted. Furthermore, since the outer surface of the pressure fluid is surrounded by a cavitation flow mainly composed of washing water and the inner wall of the pipe is always covered with a layer of washing water, the inner wall of the pipe receives from the aggregate sand.According to the second aspect, a spiral flow composed of pressure fluid and aggregate sand (hereinafter referred to as “spiral flow”) is formed in the vicinity of the inner wall of the pipe line by the spiral protrusion, and the centrifugal flow is centrifuged.

Adjacent each progressively coarser screen 34-36, auger 32 will move material more slowly towards outlet 31, to where, adjacent outlet 31 and screen 36, any remaining rock is tumbled more, while traveling the least towards the outlet.Most preferably, auger 32 will have a variable pitch, which may be varied in discrete steps or may be continuously varied. For example, if the initial aggregate is comprised of 80 percent fine sand which passes through screen 33, than the initial screen 33 will have 80 percent of the received material actively passing through at a given moment. One consideration in the design of the variable pitch is the consideration of the amount of active screen. As an adjunct to this principle, it is recognized herein that the screens may be varied in surface area, diameter, and even geometric outline to better optimize performance for a particular source material having particular size range or other characteristic that affects the proportion of processing times needed for a given stage. However, as the aggregate progresses towards the outlet, less of the fine sand remains, reducing the amount of active screen surface, and thereby requiring more time for removal. Most preferably, adjacent finer screen 33 auger 32 will move material more quickly towards outlet 31.
