1. 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.
2. Separation of Belgian Magic Star Diamond:
the beneficiation process of Belgian Magic Star Diamond generally includes preparation, roughing and cleaning. The preparation operations before beneficiation of Belgian Magic Star Diamond generally include crushing, screening, ore washing, grinding, hydraulic classification, etc. The purpose is to create good conditions for beneficiation in advance, so that the beneficiation can be carried out smoothly and obtain good results< Crushing
1.1. Crushing is the main preparation operation before the separation of Belgian magic star diamond primary ore. in the crushing stage, on the one hand, the coarse-grained ore should be fully dissociated, on the other hand, the crushing of Belgian Magic Star Diamond crystal should be reced as far as possible. In the process of ore crushing, the requirement of protecting crystal is more strict than crushing other ores. The crushing equipment is mainly jaw crusher, There are also gyratory crushers, hydro crushers, etc.
1.2. Screening
there are many places that need to use screening operation in Belgium Magic Star Diamond beneficiation. On the one hand, screening can timely separate the ore with appropriate particle size in the crushing stage, avoid excessive crushing of ore, rece power consumption and improve efficiency, It is also good for crystal protection: on the other hand, it can prepare for the next mineral processing operation. The screening equipment is the screening machine, the most commonly used is the vibrating screen, followed by the shaking screen.
1.3. Ore washing
the Belgian Magic Star Diamond placer and some primary ores contain a lot of clay minerals, It must be removed before mineral processing. Ore washing is the process of removing clay material from ore, including two stages of dispersing clay and separating the dispersed clay material from granular material. Commonly used ore washing equipment include high-pressure water gun, cylindrical ore washing machine, trough ore washing machine, etc.
1.4, The main purpose of grinding Belgian Magic Star Diamond ore is to dissociate all or most of the monomers of the fine Belgian magic star diamond in the ore, so that it can be recovered in the next step of mineral processing, Selective grinding can grind most ores to the required size, discard tailings and improve efficiency. Grinding operation is usually carried out in a rotating cylindrical mill. The mills include ball mill, rod mill and autogenous mill, The basic principle is that the medium (or ore itself) is used to grind the ore with impact phase.
1.5. Hydraulic classification
when the particle size of fine materials is separated, it is difficult to use the screening method, The basic principle of hydraulic classification is based on the difference of settling velocity in fluid e to the difference of particle size (or density).

5. Quartz sand is a very important non-metallic mineral. China is rich in quartz sand resources. According to reliable analysis, only Fengyang quartz sand can be exploited continuously for 100 years. Quartz sand, as we usually say, refers to the sand made by hand. It is the machine-made sand proced by mining large quartzite and crushing, grinding and other processes. It can be used as raw material for molding sand, manufacturing glass and ceramics, and even the main raw material for solar panels. The quartz sand used by people is pure quartz sand, but when the quartz stone is mined out from the mountain, it will carry a lot of soil, and a lot of fine powder will be proced in the process of quartz sand making, which will affect the purity of the finished quartz sand, so it is necessary to wash the ore in the proction process. There are two purposes of ore washing in the whole quartz sand proction process: first, to remove mud and improve the efficiency of crushing and grinding; The second is to improve the purity of finished quartz sand. Due to different purposes, the ore washing equipment used will naturally be different. Now we will tell you how to choose the appropriate ore washing equipment. Quartz is a raw ore mined from the mountain, which is mixed with a lot of soil. As mentioned above, soil has a negative effect on further crushing and grinding. Quartz stones are large lumps with a diameter of more than 20 mm, so it is necessary to use a strong and rable roller washer. The drum washer adopts the drum type structure, and the water spray pipe is installed inside the barrel. After the ore is sent to the drum washer, it is taken up under the rotation of the barrel, and then it is washed by the water spray pipe to realize the desliming operation. The advantages of the roller washer are: large feed size, large handling capacity, very suitable for cleaning large stones. It is the best choice to desliming quartz here. Quartz will turn into quartz sand after a series of treatment, because a large number of fine powder will be proced when crushing quartz, so in order to obtain pure quartz sand, it is necessary to wash the quartz sand in the last link. The spiral sand washer is recommended here. It is suitable for the washing operation of medium fine and coarse-grained materials. It is used for the washing, grading and impurity removal of highway, hydropower, construction and other instries, as well as the washing operation of fine and coarse-grained materials. It is widely used in various quartz sand factories. The wheel bucket type sand washer is also commonly used in China, but this kind of equipment is mostly used to clean sand and stone, and rarely used in quartz sand washing. In some places, through the transformation of the dewatering screen, adding a spray pipe in front of the dewatering screen can also achieve better ore washing effect.
6. The characteristics of roller screen structure
the standard screen is composed of a set of sieves with a certain sieve ratio, the upper sieve hole is large, the lower sieve hole is small, and there is an upper cover and a sieve bottom. Some standard sieves also have a base sieve. There are special national standards for the sampling of test materials; The sampling method and sample quality should meet these standards.
in some cases, the screen surface of Henan vibrating screen is conical, and it is installed horizontally or slightly inclined. The material is fed into the screen barrel from one end, and moves to the other end with the rotation of the screen barrel. In the process of moving, fine materials fall into the funnel under the screen through the screen hole, and coarse materials larger than the screen hole are discharged from the other end. The drum screen is a low-speed screening machine, which runs smoothly and is installed in high-rise buildings with less vibration. The disadvantage is that the screening efficiency is low and the treatment capacity is also low. The cylinder screen is often used as wet screen and also as washing machine. Because of its simple structure, some small quarries use it as stone grading
the structure of roller screen is composed of several rollers arranged in parallel, generally 6-10 rollers, up to 20 rollers. The roller is provided with an eccentric disc or a triangular disc. The roller is driven by motor and recer through sprocket or gear to rotate. The direction of rotation is the same as that of material flow, and the inclination angle of screen surface is generally 12 ~ 15 degrees. The roller screen is mainly used for raw coal classification, large gangue demedium removal, and crop material screening in coking plant and ironmaking plant. Although the structure of roller screen is bulky and the screening efficiency is low, the work is very reliable< br />
when the resonance screen works, the screen box moves and the spring is compressed to store the potential energy; When the screen box moves in the opposite direction, the spring will release all the stored potential energy and convert it into kinetic energy of the screen box to support the resonance screen. The working system of resonance screen adopts the motion mode of potential energy and kinetic energy transforming each other, so as to rece the function consumption of mechanical work
to sum up, the advantages of resonance screen are high proctivity and screening efficiency, low power consumption, large amplitude and small dynamic load transmitted to the foundation, so the development situation of resonance screen is relatively good. However, the application of the equipment is limited by its complex structure, large machine mass, unstable amplitude ring operation, complex adjustment and easy damage of screen box components e to large impact load. These shortcomings have become the focus of research and development and improvement of resonance screen in the future, which will expand the application scope of resonance screen and make the kinetic energy more stable< br />
