GPSF high-frequency vibrating screen

The high-frequency vibrating screen is referred to as the high-frequency screen. The high-frequency vibrating screen (high-frequency screen) is composed of a vibrator, a slurry distributor, a screen frame, a frame, a suspension spring, and a screen. High-frequency vibrating screens are the most important screening machines in the mineral processing industry. It is used to separate solid-containing and broken ores, the particle size is about 200μm, and it is suitable for completely wet and dry raw materials. The frequency of the vibrating screen is mainly controlled by an electromagnetic vibrator mounted above the vibrating screen and directly connected to the surface of the vibrating screen. Its high-frequency characteristics make it different from ordinary vibrating screens.

High-frequency vibrating screens typically operate at an angle of inclination, traditionally varying from 0 to 25 degrees, and up to 45 degrees. Also, it should run on low stroke with a frequency range of 1500-7200 rpm.


In addition to the various excellent performances and functions of ordinary dewatering screens, the dewatering screens are combined with thickeners for dry tailing of tailings, which is a better dewatering screen and tailings dry discharge equipment.

  •    The side panels of the screen are connected to all connecting beams using ring groove rivets.
  •    The screen surface is made of modular stainless steel or polyurethane slit screen, and the mesh diameter is ≤0.1mm.
  •    The screen is light in weight, easy to assemble and disassemble, and easy to maintain.
  •    The vibration exciter uses a seat-type exciter or a side-vibration flange-type exciter. The vibration of the exciter is lubricated with grease or thin oil.
  •    The overall strength of the screen frame, is high rigidity, long service life, stable operation, low noise, and convenient maintenance.
  •    The structure of the whole machine is reasonable, the processing precision is high, it the sturdy and durable, the dehydration effect is good, the use efficiency is high, and it is safe and reliable.
  •    The screening treatment capacity is large and the screening efficiency is high.
  •    Dynamic performance optimization of the screen frame structure.
  •    It can be designed as a double layer or a single layer by the number of layers.


The motor spread to the vibrator through the V belt, because the rotation of the eccentric shaft causes vibration, making the screen deck do circular tracking movement, thereby making the mineral roll and vibrate on the surface of the screen.

The large the surface of the screen, the size of the material than the screen pore that will fall under the screen to achieve the purpose of screening.


  • Adopt high frequency
  • Destroyed the tension on the surface of the slurry and the high-speed oscillation of the fine-grained material on the sieve surface
  • Accelerated large density of useful minerals and separation
  • Increased probability of contact with the mesh of the separated particle size
  • Good separation condition
  • The material smaller than the separation particle size, especially the larger particles and the slurry, is passed through the sieve to become the undersized product.
  • No rotating parts, and no need to add lubricating oil;
  • The structure is simple, easy to maintain, durable, low failure rate;
  • The vibrator uses the resonance principle. The dual mass is in the critical resonance state, and the required driving power is small. There is no large starting current at startup, and the noise is low;
  • After the vibrator is started, the amplitude can be instantaneously reached. When parked, its amplitude disappears instantaneously, allowing for direct start and stop at rated voltage, current, and amplitude.
  • The excitation or amplitude of the sieve body can be adjusted. The particle size of the sieve can be controlled by changing the excitation force of the sieve body (adjusting the excitation), which is very beneficial for ensuring the concentrated taste of the ore with different crystal sizes;
  • While the sieve body vibrates, the relative vibration of the screen strips also occurs, and the gap of the screen is not easy to block.


  • The GPSF Vibrating screen is designed with a new principle. It is a new structure of a high-efficiency screen vibratory screening machine, generally using nylon or stainless steel sieve plates.
  •  The vibration exciter drives the screen surface through the transmission mechanism for high-frequency vibration, and the screen box is stationary. The vibration system is designed to work in the near resonance state. The whole machine is damped and supported so that the ground does not bear the dynamic load. The screen machine does not need to be made into a foundation. It can be installed directly on solid and flat ground or an ordinary steel structure platform to work normally.
  •  The vibration frequency of the screen surface is 50Hz, the amplitude is 0~2mm, and the vibration intensity is 8~10 times the gravity acceleration, which is 2~3 times of the vibration intensity of the general mechanical vibrating screen. The screen surface is not easy to block holes, the screening efficiency is high, and the processing capacity is large. It is especially suitable for the screening of fine-grained powder materials. The graded particle size is 0.074 to 1 mm.
  •  The screen surface consists of three layers of different flexible screens. The bottom steel wire core polyurethane mesh is a support net, and a double-layer stainless steel wire braided composite mesh with different wire diameters and mesh holes are laid on the upper surface. The composite mesh layer is a working net, which is directly contacted with materials for screening work, and the lower layer of the composite mesh is a bottom mesh for distributing force and transmitting vibration to ensure high screening efficiency and long service life of the working net. There are hooks at both ends of the screen to facilitate the loading and unloading of the screen and adjust the tension. The feed buffer sieve plate distributes the slurry evenly to avoid damage caused by direct impact on the screen.
  •  The installation angle of the sieve machine is convenient and adjustable, and the inclination angle of the wet screening installation of the concentrator is generally 25 ± 2°. Adjust the drying angle according to the required mineral grain size. When the inclination angle is close to 55°, the fineness can reach 300 mesh, and the screening efficiency can reach about 75%.
  •  The vibration parameters of the sieve machine are controlled by a computer, and the vibration parameters of each vibrator can be adjusted separately. The instantaneous high-vibration function is set on the high-frequency screen of the high-frequency screen. By setting the intermittent strong vibration parameters, the screen surface is cleaned regularly to prevent the hole from being blocked.


Iron ore, limonite: Uses the high-frequency vibration fine screen to use in the ore concentrate graduation, by the screen-out low-grate large grain continually living body, is same when the ore mill handing ability, but stably enhances the ore concentrate personal status 1%-3%, And reduced the utility over-grinding. Under the same ore concentrate personal status premise, the ore concentrate average granularity increases thickly but causes the ore concentrate to filter the condition improvement, which may cause to filter the cake moisture content to reduce 0.5%-1%.

Tungsten, tin, tantalum, niobium, finely quarry: Uses the high-frequency vibration fine screen to replace the spiral sorting machine, the cyclone graduation, or with spiral sorting machine, cyclone combination graduation, with grinding machine close up, but remarkably reduces the great density utility smashing, has enhanced the dressing efficiency, the returns-ratio may enhance 10%-15%.

Quartz sand, long quarry: Uses in the stick rubbing-the screening flow, but stably produces the certified product.

The metal power system takes: Produce -38mu m between -351μm(400 items to 40 items) of the metal powder.
