Features:

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, 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, 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.

Principle:

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

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

Advantage:

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, are passed through the sieve to become the undersize product.

No rotating parts, 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 concentrate 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.

Structure:

The GPSF Vibrating screen is designed with a new principle. It is a new structure of 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 a 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 of 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 is 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 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.

Application:

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, 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(400item to 40 item)the metal powder.
