A new type of coarse particle flotation machine for rough grinding and flotation in mines

 Coarse ore flotation has always been one of the key technologies for mine coarse grinding and flotation to reduce energy consumption. An iron ore plant in Anhui Province has a very small content of mica in the iron ore of the first grinding product. Recovery value. However, there are generally two ways to recover mica at present: one is coarse-grained regrind and reselection; the other is to choose equipment suitable for coarse-grained mineral flotation. However, during the inspection of the production site, it was found that many of the mica minerals in the second-stage grinding products in this iron ore did not meet the particle size requirements of flotation, and the density of mica was small, and most of them showed flaky structure. The overflow of the cyclone ran out, causing the inspection and screening operation to be blocked first, so regrinding is not suitable for the recovery of coarse mica.     The design principle of coarse-grained flotation machine is that coarse-grained

How to perform high-intensity work on filter thickener

 The process adopted by the coal industry in my country is mainly based on wet coal preparation, and a large amount of slime water will be produced in the process of coal processing. Therefore, the treatment of slime water is a key link in the production of a coal preparation plant. The operation of the slime water system is related to whether the coal preparation plant can be normally produced. At the same time, it also involves the water of the coal preparation plant and the recovery of coal resources. Protect many aspects of the ecological environment. The thickening and clarification of slime water is an important link in the treatment of slime water. Under the current situation, we can use the rake thickener based on the principle of gravity sedimentation as the main equipment to apply, and then use the principle of gravity sedimentation to concentrate the slime water The equipment efficiency drops greatly, which will cause the overflow water concentration to exceed the standard,

A new technology of high-efficiency concentration of ore slurry--filter thickener

 Most of the current thickening equipment is based on rake thickeners. The rake thickeners use the principle of gravity sedimentation to achieve concentration and clarification. This can be widely used in washing water clarification and other links, but with mechanization Continuous popularity and progress. The concentration efficiency of equipment using the sedimentation principle will be greatly reduced, which will cause the overflow concentration to exceed the standard and affect normal production. Therefore, in this case, we have to further carry out a necessary study on the principle of suspension and sedimentation and the enrichment equipment. Under such circumstances, a new type of filter thickener that uses the principle of pressure filtration to achieve the old high-efficiency slurry thickener is proposed. Compared with the gravity sedimentation thickener, the filter thickener has the advantages of fast concentration speed, high concentration efficiency, quick concentration a

Choice range of inclination angle of thickener

Image
When the tilt angle is 50 degrees, the concentration efficiency is the highest, and as the tilt angle continues to decrease, the concentration efficiency will gradually increase. When the angle is too low, the concentration efficiency will decrease instead. The thickening equipment is the source of the water clarification process in the coal preparation plant. The angle of the inclined plate of the inclined plate thickener has a great influence on the efficiency of the thickener. The inclined plate thickener has a bottom feed, and the type of feed is heterogeneous, so it is inclined The angle should be kept between 45-60 degrees, so the test is carried out. During the test, an inclined plate was added to the ordinary thickener . The inclined plate uses stainless steel bolts to connect the right-click glass plates of different sizes at different angles to form a combination of inclined plates with different inclination angles. At this time, 200g of the well-mixed raw materials can be ta

A worthy headbox of dual-pressure zone thickener

 The double-pressure zone thickener is mainly used for the washing and concentration of the slurry in the waste paper deinking and reducing treatment system. The machine is mainly composed of active rollers, driven rollers, and endlessly woven filters and flow boxes running around two rollers. , Discharge screw conveyor and other components. The slurry passes through the headbox, which is dewatered by the squeezing action between the filter screen and the active roller in the nip between the filter screen and the active roller. The active roller is engraved with deep grooves, which can obtain a high nip pressure, so that the slurry is concentrated on the inner surface of the mesh into a form of slurry strips. These strips are kept on the filter screen. When the slurry enters the filter In the nip between the net and the movable roller, it will be further dehydrated and then separated from the net surface, falling onto the roller surface and being scraped off and discharged by the scra

A new type of thickener-lifting thickener

Image
  Thickener is a continuous working thickening and clarification equipment, mainly used in the dehydration of tailings slurry in wet beneficiation operations, and also widely used in the thickening and purification of solid-containing slurry such as steel and sewage treatment. According to its driving mode, the thickener can be divided into two categories: peripheral drive thickener and central drive thickener. Peripheral drive thickeners have integral rake lifts to varying degrees, especially the secondary rake in the cone pit. , It will cause the defects of pressure rake. Although the central drive thickener can lift the rake, when the load-bearing bridge is too heavy or the central drive torque is too large, a new type of thickener-automatic rake thickener appears. When the thickener is working, the motor, reducer and drive transmission equipment rotate along the thickening tank, the transmission device will drive the central support through the transmission bridge and the central

How to use inclined plate thickener for tailings dry discharge

Image
 Tailings treatment is an important part of mine production. Concentration in dry tailings discharge is an important link in achieving dry stacking. It not only directly affects the processing capacity of filter equipment, but also affects the resistance of filter cakes. The particle is resistive to the filter cake, so according to the characteristics of iron tailings, there is a new type of thickener . The flow of tailings slurry in the thickener is ideally slow. As soon as the solid particles leave the flow layer, they will be considered as sediment. This model is also called shallow sedimentation. The sedimentation occurs in the void between the inclined plates. Within the cavity, but due to the small spacing between the inclined plates, it creates favorable conditions for the formation of laminar flow. The clarified overflow water moves upward along the inclined plate space, and the solid particles settle between the two plates, and only need to settle to a small distance to fall o
