In order to meet the needs of coal slurry recovery and fine particle material dewatering classification, as well as achieve the goals of large processing capacity, good dewatering effect, and strong adaptability, the high-frequency vibration dewatering screen adopts mechanical characteristics of high frequency and high vibration intensity.　　According to the requirements of mechanical structure and process parameters, the vibrator is arranged above the center of gravity of the sieve box. This arrangement makes the motion trajectory of the sieve machine elliptical at the feeding end, circular in the middle, and still elliptical at the discharging end, that is, elliptical circular elliptical motion.　　It is precisely because of this unique motion characteristic that the angle between the long axis of the ellipse at the feeding end and the screen surface of the sieve is sharp, and the angle between the long axis of the ellipse at the discharging end and the screen surface is obtuse. In this way, the movement speed of the material at the feeding end is greater than that at the discharging end, ensuring that the material can be quickly loosened at the feeding end of the sieve. Therefore, the material layer is thinner, allowing the fine-grained material to quickly layer and contact the sieve, resulting in the rupture and dehydration of the water dry film; And the material speed at the discharge end is small, which can prolong the dehydration time of the material on the screen surface, thereby improving the dehydration effect. The characteristic of the screening machine enhances the dehydration effect.　　The main function of the dewatering screen is dewatering, desliming, and desliming. It has been widely promoted and can be used for washing sand in sand and gravel plants, recovering coal slurry in coal preparation plants, and discharging tailings in mineral processing plants. It is a new type of dewatering screen that is energy-saving, environmentally friendly, low-carbon, and green, and meets the requirements of building a sustainable society.　　Sand and gravel dewatering screen, mining dewatering screen, coal slurry dewatering screen, tailings dewatering screen, high-frequency dewatering screen　　The vibrating dewatering screen has a very good screening and dewatering effect on the process flow of sand washing production lines. Currently, it is very suitable for fine sand screening and grading dewatering in many sites. For the screening of sand, it depends on the type of sand, such as machine-made sand, river sand, sea sand, etc. Generally, the mesh size of fine sand is about 20 to 40 mesh. However, it is necessary to check the mesh size of the sand and the number of particles screened to determine the size of the sieve needed for screening fine sand. Dehydration screens are suitable for screening fine sand, including materials with and without moisture. They have the function of high-frequency vibration and dehydration, and are widely used in fine sand washing processes.　　There are also many shapes of sieve holes, such as circular, square, and rectangular. Compared with other shapes of sieve holes, circular sieve holes have smaller particle sizes when passing through them under the same nominal size. The average particle size of particles passing through circular sieve holes is only that of particles passing through square sieve holes of the same size.　　The rectangular sieve has a larger effective surface area and higher production capacity. When dealing with materials with high water content, it can reduce the clogging of the sieve surface. However, it is easy for strip and sheet materials to pass through, resulting in uneven particle size of the screened products. Therefore, when it is required that the sieved material does not contain fine powder, strip and flake particles are allowed in the sieved material, the material is wet and sticky, easy to block the sieve holes, and high content of sieved material is desired, rectangular sieve holes can be used.　　Feed the screening equipment in moderation, neither too much nor too little. Too much, although the processing capacity is large, the screening efficiency is low, and J acts as a chute; Too little, the sieve processing capacity is small, and the sieve is not fully utilized. The feeding requirement is continuous and uniform, and the material should be spread along the entire width of the screen to form a uniform thick layer. In addition, it is necessary to clean and repair the screen surface in a timely manner.　　Technical parameters:Serial NumbernameunitGPS-12*31GPS-14*31GPS-18*37GPS-24*481Feed concentration%≥45≥45≥45≥452Processing capacityt/h15-1920-2528-3340-603Screen specificationsmm1200-31001400-31001800*37002400*48004mesh sizemm0.3,0.350.3,0.350.3,0.350.3,0.355Double amplitudemm457214572145721457216oscillationHz252525257Equipped with motormodelY112M-4Y132S-4Y132M-4Y180M-4powerKw2*4.02*5.52*7.52*18.58voltagev380380380380External dimensionsmm3020*2400*21003020*2600*21003527*3060*21305025*3880*26939Single point maximum dynamic loadN±2000±2500±3500±5000
