Spiral horizontal trough washer

1. The washing equipment depends on how you wash the ore. if you wash the ore, the raw materials should not be too large. You can directly use a spiral washing machine or a high-frequency screen, vibrating stone washing machine, spiral chute, shaker, etc. different raw materials have different washing methods. When washing the ore, you should choose the equipment according to the output

2. First of all, you need to determine the mud content of your stone. If the mud content is large, you can use spiral washer or roller washer. If it is small, you can directly use a vibrating washer. It is cheap and has large output.

3.

Spiral stone washer is used for desliming and screening of large amount of sand and stone in construction site, sand and stone plant, prefabrication plant and hydropower site, and also for ore separation. It can effectively handle the materials within 0-30mm, and separate the soil and ash powder on the materials into clean materials. The machine has the advantages of simple structure, easy maintenance and high washing efficiency. Spiral sand washing machine is divided into double screw and single screw. Compared with the single screw sand washing machine, the double screw stone washing machine has the advantages of high efficiency and large output, and can handle materials within 0-30mm
the double screw washer has the advantages of simple structure, easy maintenance and high washing efficiency
the rotor of the double screw stone washer adopts the central structure, the spiral blade is installed on the central shaft, and the recer is connected to the central shaft to work. With the help of the principle that the specific gravity of solid particles is different, so the settling velocity in liquid is different, an ore cleaning equipment for mechanical extension is developed.

4. Washing machine is a large-scale equipment used to clean ore in black and non-ferrous metallurgical mines, iron and steel, metallurgy, chemical instry and building materials.

5. The advantages of spiral concentrator and spiral chute are as follows: 1) simple structure, no moving parts, easy equipment manufacturing and maintenance; ② The proction capacity per unit area is large and the floor area is small; ③ The material zoning is obvious and the sorting index is high; ④ It has strong adaptability, and has little influence on the separation indexes when the feed quantity, feed concentration, feed particle size and raw ore grade change
its disadvantage is that the enrichment ratio of flaky ore is lower than that of shaker and chute, and its own parameters are not easy to adjust to adapt to the change of ore feeding properties
the spiral concentrator is suitable for treating alluvial placer, especially for those with high dissociation degree and flat shape of useful mineral monomer. For resial and slope placer, the recovery rate is lower. In addition, the ore with high mud content will rece the quality of concentrate, so it is required to enter the spiral concentrator and spiral chute after desliming and classification
the spiral washer and spiral chute are mostly used to treat cassiterite, scheelite, chromite, ilmenite, sillimanite, monazite and other minerals, and can also be used to recover heavy minerals from flotation tailings. Generally, it is used as roughing equipment, which can discard most of the tailings to get coarse concentrate. The particle size range of spiral concentrator is generally 2-0.05 mm, up to 6 mm, and the effective separation particle size is 1-0.1 mm. The spiral chute, which is the same type as the spiral concentrator, is suitable for treating fine materials and iron ore successfully. The experimental results show that the effective recovery particle size limit of spiral chute is 20 μ M. This information is provided by www.gyxxjx.com provide

6. The separation principle of spiral chute and spiral concentrator is the same, and the equipment structure is also similar
(1) the main difference is that the cross-section shape of spiral groove is different. The cross section of spiral groove of spiral concentrator is approximate ellipse, which is suitable for separating coarse iron ore; The cross section of spiral chute is cubic parabola, and the bottom of spiral chute is wide and gentle, which is suitable for separating fine ore and slime. At present, spiral chute is widely used< (2) spiral washing machine and spiral chute are mostly used to treat cassiterite, scheelite, chromite, ilmenite, hollite, monazite and other minerals, and can also be used to recover heavy minerals from flotation tailings. Generally, it is used as roughing equipment, which can discard most of the tailings to get coarse concentrate. The particle size range of spiral concentrator is generally 2-0.05 mm, up to 6 mm, and the effective separation particle size is 1-0.1 mm. The spiral chute, which is the same type as the spiral concentrator, is suitable for treating fine materials and iron ore successfully.

7. What are the differences among the stone washing machine, ore washing machine, washing machine and sand washing machine of Limai machinery? The spiral ore washing machine relies on the principle that the solid particles are different in size and specific gravity, so the settling speed in the liquid is different. The fine ore particles float in the water and overflow, and the coarse ore particles sink at the bottom of the tank. Cylinder stone washer is mainly used for desliming of artificial aggregate less than 80mm. It has the advantages of large feed particle size and low mud content of aggregate after washing. The wheel bucket sand washer has the advantages of high cleaning degree, reasonable structure, large capacity, low power consumption, less sand loss in the sand washing process, especially the transmission part of the sand washer is isolated from water and sand, so the failure rate is very low.

8. Gravity beneficiation is a method of separating ore according to mineral density difference, which plays an important role in modern beneficiation methods. After about 400 years of development, this set of mineral processing equipment once appeared floating phenomenon. However, after a long period of development, gravity separation still exceeded flotation and magnetic separation in terms of ore processing capacity. From the workshop type jigger to the emergence of shaker, gravity separation process has been basically formed. The main types of gravity separation process are classification, jigging, shaker and chute, The above gravity separation process is almost the only mineral processing method at the end of the 19th century, which also established the status of gravity separation in mineral processing methods. In the 1940s, under the guidance of the Americans, gravity separation broke through the original vertical flow and inclined flow separation modes, increased the application of static separation and rotary flow, that is, the advent of spiral washer, laid the basic pattern of modern gravity separation process

gravity beneficiation is mainly aimed at coarse-grained ores, which has a great advantage in the preconcentration application of coarse-grained ores and the separation of fine slime, which is beyond the ability of other beneficiation processes and has been widely used. Gravity dressing equipment is also very simple in terms of manufacturing, and the technology is relatively mature. In the proction of mineral processing, expensive reagents are not consumed, which not only saves the cost, but also reces the environmental pollution caused by the tailings discharged from the gravity mineral processing equipment. With the development of society, people pay more attention to the ecological environment, and the emergence of energy crisis, the graal rection of mineral resources, the superiority of gravity dressing has been affirmed again, and a new development trend has appeared, In recent years, a variety of dynamic heavy medium separators and flow film processing equipment are the signs of this development

as a manufacturer of large-scale mineral processing equipment, Minglei heavy instry group realized that gravity mineral processing equipment was developing towards large-scale, multi-layer and centrifugal force application. In the early theoretical research of gravity mineral processing technology, it tried to express the essence of the process with simple concepts, with different views, most of which focused on the explanation of process phenomena, In the 1950s, with the emergence of a large number of modern ideas and instruments, experts and scholars began to use modern measurement techniques, including rapid photography, radiolocation, optical measurement and other methods to visually describe the movement of particles and media. However, in order to make analytical expression of these observation results, few have done so far, So far, there is no qualitative development of gravity mineral processing theory< Up to now, except for the problem of particle sedimentation, most of the process principles have not been clearly defined. It is difficult to make quantitative calculation. So in recent years, the research based on probability statistics and simulation similarity has been carried out. Through the statistical analysis of process variables or the extension of essential knowledge, an empirical mathematical model or theoretical similarity relation is established, which can be used as the basis for proction calculation, control or equipment enlargement design. Therefore, gravity beneficiation is moving from empirical technology to scientific and mathematical way

China is a country rich in mineral resources. The development of gravity beneficiation technology has also experienced the transformation from ancient times to modern times, and a large number of large and medium-sized gravity concentrators have been established. Great progress has been made in the research of beneficiation methods. Gravity separation method has been popularized and applied to treat iron ore, and heavy medium pre concentration workshops have been established in lead, zinc and antimony non-ferrous metal mines, Of course, gravity separation method is also widely used in building materials, chemical instry, especially coal instry, and has reached the world advanced level. However, there are still problems in the development. There is still a gap between China's concentrators and developed countries in terms of technology management, material and energy consumption, which requires further efforts in order to reach the world's advanced level in an all-round way.
