Description
Technical Field
The invention discloses a continuous centrifugal concentrating machine, and belongs to the field of concentrating equipment.
Background
The main minerals of the titanium tailings in Panxi area are ilmenite, spodumene and plagioclase, and the secondary minerals are silicate, aluminosilicate, carbonate mineral and trace metals such as amphibole, olivine, chlorite and the like. The titanium ore in the titanium-selecting tailings has finer granularity, the TiO2 distribution rate of the-0.048 mm size fraction is generally more than 55%, the monomer dissociation degree is higher, and the TiO2 distribution rate of the +1.8mm size fraction is generally 9.9%. This determines the separation of the minerals containing titanium, chromium, cobalt and scandium from the tailings of titanium separation, and care must be taken in the separation of the fines fraction. Ilmenite and other minerals have certain differences in various properties such as density, magnetism, electricity and the like, but because the micro-fine ilmenite has small granularity and large surface energy, the recovery effect is not obvious by applying a single magnetic and electric ore separation method, so that the recovery effect of titanium from the titanium-selecting tailings is not good yet. The conventional centrifugal beneficiation and flotation have better effects in the aspect of recovering fine-particle-grade minerals, and are important points and hot spots of the conventional comprehensive recovery technology of the tailings of the beneficiated titanium.
Centrifugal mineral separation is a mineral separation method which has higher recovery effect of micro-fine particles and is more environment-friendly than flotation, and is one of essential basic technologies in mineral development in China. The application of the centrifugal ore dressing mode mainly refers to the technical application of a centrifugal ore dressing machine. With the continuous development of the mining industry, the types of centrifugal ore separators are more and more, and the application field of the centrifugal ore separators in industry is wider and wider.
The rotary drum of the centrifugal ore separator rotates at a certain revolution and the ore pulp is fed into the inner wall of the rotary drum from the ore feeding separator through two positions of the ore feeding mouth. The ore pulp rotates at a high speed along with the drum, heavy minerals are deposited on the inner wall of the drum and rotate along with the drum under the action of centrifugal force, light mineral grains in the ore pulp rotate along with the drum at a certain differential speed, flow from a mineral feeding end to a mineral discharging end along the gradient direction of the drum at a certain spiral angle in the rotating process, and are discharged from the tail end through a mineral discharging and separating device, so that tailings are obtained. After 3min of sorting, the ore feeding and separating device automatically rotates to the position for discharging the ore concentrate, ore feeding into the rotary drum is stopped, after tailings are discharged, the ore discharging and separating device automatically rotates away from the original normal position to intercept the ore concentrate, then a high-pressure flushing water valve is automatically opened, the ore concentrate deposited on the inner wall of the rotary drum is flushed by the high-pressure flushing water, the high-pressure water valve is automatically closed after the ore concentrate is flushed, and after the ore concentrate is discharged, the ore discharging and separating device and the ore feeding and separating device automatically reset to start the next sorting cycle.
At present, the process for recycling ilmenite by centrifugal machine in production site is more applied than the process for recycling titanium by floatation, mainly because the centrifugal concentrator can obtain good effect in a laboratory, and can efficiently recycle micro-particle ilmenite. The main working principle of the centrifugal concentrating machine is as follows: the rotary drum rotates at a certain rotating speed, and ore pulp is fed into the inner wall of the rotary drum from the ore feeding and separating device through two positions of the ore feeding mouth. Under the action of centrifugal force, tailings are discharged through the ore discharge and separation device, after the tailings are discharged, the ore discharge and separation device automatically rotates away from the original normal position to prepare concentrate interception, until the concentrate is discharged, and the next working cycle is started. That is, the conventional centrifugal concentrator cannot continuously work, and the throughput per unit time can be improved only by continuously maximizing equipment, which has a significant application defect in production and limits the application of the centrifugal concentrator in mineral separation. The focus of current centrifuge research is on continuous centrifugal concentrators. The patent publication No. CN 103203291A discloses a continuous ore discharge centrifugal concentrator, hundreds of components are added on the basis of a discontinuous centrifugal concentrator, and the water consumption of ore discharge by back flushing is high, the structure is complex, the production is easy to be damaged, the automatic control components are more, and the effect is poor. The patent application publication No. CN 104190532A discloses a multipurpose electromagnetic centrifugal continuous concentrating machine, wherein the ore discharging mode is mainly to discharge concentrate by back flushing water, and a large amount of back flushing water is required to be consumed to remove the concentrate attached to the inner wall of a rotary drum.
