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. 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. It is divided into spiral washing machine and cylinder washing machine. Ore washing is the process of removing clay material from ore; It is widely used in phosphate and iron ore washing and desliming instry. It is set before crushing, gravity separation, magnetic separation and flotation operation to eliminate the influence and harm of slime on these operations, improve operation efficiency and obtain good separation index. Ore washing machine is a large-scale equipment used in black and non-ferrous metallurgical mines, iron and steel, metallurgy, chemical instry and building materials to clean ores and stones. The ore washing machine has a large processing capacity and is an ideal equipment for enterprises that meet the requirements of high proctivity on the cleanliness of ores and stones. Ore washing can avoid the blockage of crushing and screening equipment by slimes in raw materials containing slime. If raw materials contain soluble useful or harmful components, ore washing should also be carried out

4. 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

5. 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.

1、 Sorting

sorting is a mineral processing method to separate useful minerals and gangue minerals by using the physical properties of ore, such as surface characteristics, optical properties, electrical properties, magnetic properties, radioactivity and the absorption and reflection ability of ore to rays. Sorting is mainly used for the separation of massive and granular materials, such as removing large waste rock or picking out large rich ore. The upper limit of separation particle size is 250-300 mm, and the lower limit is 10 mm. For some precious minerals (such as diamond), the lower limit is 0.5-1 mm. For the separation of non-metallic minerals, sorting can be used to preconcentrate or obtain final procts. It has the following advantages: it can partly replace the selective mining method with low efficiency and high cost; Large pieces of waste rock are removed in advance to save the transportation, crushing, grinding and mineral processing costs of waste rock; Improve the grade of ore and the content of useful minerals; The waste rock can be used for backfilling and building materials to rece its environmental pollution

sorting can be divided into three ways: flow sorting (continuous sorting), partial sorting (heap sorting) and block sorting. Flow separation is to make a certain thickness of material layer continuously pass through the detection area; Partial separation and block separation means that one ore or one ore passes through the detection area alone. The quality of block selection or partial selection is better. At present, block selection is the main method in instry. There are two types of block picking: manual picking and mechanical picking

Manual sorting

according to the appearance characteristics (color, luster, shape, etc.) between ore and waste rock, ore or waste rock can be sorted out by hand, and can be divided into forehand sorting (picking useful minerals from ore) and backhand sorting (picking waste rock from ore). It is mainly used for the separation of some ores which are difficult to be sorted by mechanical methods or whose quality can not be guaranteed. For example, asbestos with long fiber and massive mica are selected from ore; Large gangue is picked out from kaolinite of coal measures. Hand picking is the simplest way of picking, but it has high labor intensity and low efficiency

2. Mechanical sorting γ According to the difference reflected by radiation or the difference of natural radiation ability of ore, the separation of ore and gangue is realized by means of instrument. For example:

radioactive sorting: associated ores containing uranium and thorium elements

ray absorption sorting: coal, iron and chromium ores

luminescent sorting: diamond, fluorite, scheelite and asbestos

photoelectric sorting: gypsum, talc, asbestos, marble, limestone, magnesite, wolframite, diamond

electromagnetic sorting: metal sulfide ore and oxide ore

With the development of modern science and technology, especially the application of electronic computer, the mechanical sorting is becoming more and more perfect, the efficiency is greatly improved, and the application field is graally expanded. At present, photoelectric sorting is more commonly used in the non-metallic ore instry with mature equipment

Fig. 2-1 mechanical picking principle diagram

Mechanical picking principle is shown in Fig. 2-1. The ore to be selected falls into the radiation area proced by the radioactive body evenly through the vibrating chute. Different physical signals will be generated after the ores of different properties are irradiated. The detector will send the detected signals to the information processing system, which will amplify and identify the signals, and finally send the command signal to the actuator, The actuator can divide the material into useful ore and waste rock. Generally, the high-speed air valve with up to 300 times per second is used in the actuator, which greatly improves the proction efficiency. The modern electronic technology is used as the control system with high degree of automation. The modern sorting machine has become a high-tech mineral processing equipment with camera, computer and so on

Friction ore washing is a kind of technology to treat the ore which is stuck with clay or contains more mud, including crushing and separation. For non-metallic minerals such as quartz and feldspar, after long-term weathering, the primary ore deposits exposed on the surface are wrapped by the decomposition procts of clay minerals or rocks, forming cemented or argillaceous bodies. In this case, the method of friction washing and disintegration, which is different from ore crushing, is often used to separate mineral monomers before separation, which can not only remove the surface adhesion of mineral particles, but also prevent unnecessary crushing or over crushing. Usually, minerals are soaked and washed in water medium, supplemented by mechanical agitation (adding dispersant if necessary). With the help of friction between minerals, mineral particles adhered by slime are separated from clay impurities, which is called friction washing. The surface of some weathered or primary fine-grained non-metallic minerals can be purified by friction washing to expose the surface which can reflect the properties of the ore itself. After the impurities are removed, not only the mineral particles themselves can be purified, but also the conditions for the subsequent purification operation (such as flotation) can be improved. Scrubbing (ore scrubbing) can not only be used as the preparation for other purification operations, but also complete the purification of minerals separately

Fig. 2-2 friction ore washing machines are mainly friction ore washing machines, cylinder ore washing machines, trough ore washing machines, etc. In addition, the double screw scrubbing machine is often used in the scrubbing and purification of some non-metallic minerals such as quartz and diatomite. The structure of friction washer is shown in Figure 2-2
