The gate chute is directly inserted into the feeder at the feeding port of the vibrating screen, improving the environmental protection effect.　　3. The vibration of the entire screen mesh is reduced, and the screen edge does not participate in the vibration, which reduces the mass of vibration and reduces the impact on the floor slab.　　4. The vibration source is placed on the outside of the screening box, which is easy to disassemble and saves labor costs.　　5. Small vibration mass, low motor power, and low energy consumption.　　6. The vibration source is placed on the outside of the screen box, making it difficult for dust to enter the bearing chamber and extending the service life of the bearing.　　7. The feeding system is sealed at the feeding end of the vibrating screen, and the material flows from the chute gate to the feeding port, then to the discharge chute of the vibrating screen and its upper screen material, and finally to the discharge funnel and chute of the lower screen material, achieving complete hard connection sealing. There are no dust overflow points, which can reduce the dust removal ports of the screening system under the blast furnace trough, and save the dust removal energy consumption of all vibrating screens, as well as the material and labor costs of environmental protection equipment maintenance to a greater extent.　　8. Compared with the feeding environmental protection integrated machine, the dual source linear environmental protection screen has a more user-friendly design and simple and convenient maintenance.

GPS series high-frequency vibration dewatering screen

Product Features

　　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

HFS series fertilizer sieve

Product Features

　　HFS type fertilizer sieve is a new type of vibrating screen. Mainly used for grading various compound fertilizers and other bulk chemical materials. The HFS fertilizer screening machine has introduced the new technology of "Tailak" structure and ring groove rivets from the United States. Low vibration noise, high screening efficiency, and easy maintenance.　　The screening surface of this fertilizer sieve is driven by vibration through an excitation device, used for particle size classification of medium and fine materials. The main characteristics of fertilizer screening in terms of structure are: vibration exciter excitation, dual motor drive, stainless steel anti blocking screen surface, and the screening machine adopts cold riveting technology (traditional welding, cold riveting technology has better stress on the screen box and longer service life). In terms of working principle, the HFS fertilizer sieve utilizes the principle of probability to complete the entire screening process at a very fast speed, reducing the time required for material screening to only half of that of a regular sieve, while its processing capacity per unit screen area is twice that of a regular sieve. Therefore, it can be considered that the screening performed in fertilizer screening belongs to "rapid screening". In addition, the fertilizer sieve holes are not easily clogged, and one screening machine can simultaneously obtain several particle sizes of products, with a wide range of screening particle sizes.　　The HFS fertilizer sieve consists of three parts: sieve box, exciter, and support device. The sieve surface is installed on the sieve frame. The screen surface of the fertilizer sieve undergoes reciprocating vibration, using a dual axis inertia exciter and driven by two electric motors. Two sets of exciters operate synchronously in reverse to generate excitation force, drive the sieve mesh, force the material to undergo parabolic motion, and pass through the sieve layer by layer. The mesh material of the fertilizer sieve is stainless steel, and the hole type is anti blocking hole type. The material does not gamble, get stuck, or stick. Due to the use of a two-layer sieve, the material moves in layers, the material flow is thinner, and it is easier to sieve. The efficiency can be doubled, truly reflecting the technical principle of probability screening.　　The research on HFS fertilizer sieve is at the forefront in China. The exciter of the fertilizer sieve adopts a precision steel casting shell, a dual axis structure, and two bearings on each axis. It has a large bearing capacity, reliable lubrication, and can operate continuously without interruption under high temperature and high dust conditions.　　The HFS fertilizer sieve has been optimized based on the original design. As fertilizer sieves are usually arranged in high-rise buildings, a secondary shock-absorbing platform has been specially designed, which can eliminate at least 3-5 times the vibration load, reduce the impact of equipment on the floor, and facilitate long-term safe operation for users; This technology is innovative in design and leading domestically.　　Technical Parameter：modelMotor PowerFeed particle sizeprocessing capacityHFS-257.5*2<3025HFS-5011*2<3050HFS-10011*4<30100HFS-1507.5*8<30150HFS-20011*8<30200
