1. Install the damping rubber pad
In order to avoid the movement of the vibrating screen during operation and reduce noise, the three damping rubber pads in the accessories should be installed on the bottom of the base of the vibrating screen during installation, and the vibrating screen must be fixed with anchor screws; 2. Net installation and removal
①. The screen of the rotary vibrating screen should be installed on the screen frame. To install or disassemble the screen, the screen ring (frame) should be removed first, and the discharge port should be placed on the platform, and then the screen frame should be lowered. Put the screen on the screen frame, then put the screen compression ring, and fix it slightly symmetrically with the screws according to the vertical direction of the screen. After confirming that the screen has no creases, is evenly elastic, and has a square shape of the screen holes, respectively insert the screws into the screw holes. In the middle, slowly and evenly rotate and tighten one by one, and finally cut off the excess screen.
②. Because the screen frame and the screen pressing ring are designed with a dovetail groove structure, the more you press the screen, the tighter the screen will be to ensure that the screen is tight; if the customer has no special requirements, the screen frame is usually made of aluminum alloy, and the screen There is a certain range for the gap between the pressing ring of the grid frame and the screen frame. If it is an extra-coarse screen, the gap should be increased. If it is not in place, tap it gently and evenly with a wooden hammer, or use a vise to tighten the edge. When screwing the screws, special care should be taken during this process, so as not to cause the pressing ring of the screen frame to break.
③. According to the requirements of the materials to be screened, the mesh number of the screen should be selected, the lower layer is for the larger mesh number, and the upper layer is for the smaller mesh number. It is necessary to ensure that the mesh number of the screen is selected correctly. If the mesh number is not standard, it will affect the production quality. In addition, the screen with a larger mesh is lighter and thinner, and a screen with a smaller mesh should be lined underneath to prolong the service life of the screen.
④. The screen is a vulnerable part. During the use of the rotary vibrating screen, it should be regularly checked for broken wires, leaks, depressions, deformation and other damages. If the screen is damaged, it should be replaced in time to avoid accidents. The breakage of the screen causes the rubber ball to fall into the material.
3. Precautions for use of screen bottom, rubber ball and sealing strip
There are rubber balls placed on the bottom of the screen. Due to the vibration of the rotary vibrating screen, the rubber balls are forced to bounce and move continuously along the circumferential direction on the bottom of the screen to achieve the purpose of cleaning the screen and also to ensure the screening output and accuracy. , During the use of the rotary vibrating screen, certain wear and tear will also occur. It should be checked regularly and replaced if necessary to prevent it from falling into the material. The backing is fixed on the screen frame by screws. Long-term vibration will cause the screws to loosen or even fall into the material. Therefore, it should be checked regularly, and if it is loose, it should be tightened in time.
The main function of the sealing strip of the rotary vibrating sieve is to prevent the latent leakage of the material. It should be checked regularly. If there is inelasticity due to long-term compression, it should be replaced in time to prevent the occurrence of latent powder leakage.
4. Adjustment of excitation force and amplitude
①. By adjusting the phase angle of the weight block or increasing or decreasing the weight block, the rotary vibrating screen can produce different exciting forces and amplitudes, so as to change the movement track of the material, so that the material can be fully vibrating and screened on the screen surface , so as to meet the screening requirements of different materials and achieve the highest screening accuracy and output.
②. Changing the angle of the weight can change the movement track of the material. Loosen the weight block and tighten the screw to move the weight faster, and then tighten the clamping screw after making the required angle relative to the dial. The smaller the included angle, the greater the exciting force. Usually the included angle should not exceed 90°.
③. The adjustment of the amplitude can be divided into two aspects: horizontal and vertical. The size of the amplitude directly affects the output of the screening. (This article is provided by Xinxiang Machinery Co., Ltd.) The increase of the horizontal amplitude makes the materials on the screen move to the edge faster, and the vertical amplitude The increase makes the material on the sieve bounce stronger. The amplitude of the vibration is adjusted by adjusting the weight of the upper and lower weights. The amplitude should not exceed a certain range, otherwise it will affect the service life of the rotary vibrating screen.
5. Adjustment of the outlet position
The position of each discharge port of the rotary vibrating screen can be adjusted according to the site conditions of the user. The adjustment method is very simple. Remove the fastening lock and change the position of the discharge port according to the circumferential direction. After confirming the position, install the fastening lock. .

Everyone knows that whether it is a rotary vibrating screen or a linear vibrating screen, the most important thing when screening materials is the screen mesh. The screening of materials is controlled by the mesh size on the vibrating screen, and the effective selection of the mesh is the main factor in improving the efficiency of the vibrating screen! Today, the editor will organize how to reasonably select the screen mesh for the rotary vibrating screen. I hope the majority of users can be helpful.



1. The aperture of the rotary vibrating screen mesh refers to the size of the standard screen mesh, and the wire diameter of the screen mesh refers to the diameter of the woven metal wire.



2. Mesh size refers to the number of mesh holes in a length of 2.54 centimeters (1 inch), abbreviated as mesh size. For example, 80 mesh means that there are 80 holes per square inch, and 700 mesh means 700 holes. The higher the mesh count, the more holes there are. In addition to representing the mesh size of the sieve, it is also used to represent the particle size that can pass through the sieve. The higher the mesh size, the smaller the particle size.



3. The conversion method between mesh size and aperture micrometer of the sieve: Generally, in China, the grading system is based on the Taylor sieve system, with a 200 mesh mesh size of 0.074mm as the benchmark. The 100 mesh aperture is 200 * 0.074mm ÷ 100=0.148mm/325 mesh aperture is 200 * 0.074mm ÷ 325=0.045mm/.

4. The size of powder particles is called particle size. Due to the complex shape of particles, there are usually several representation methods, such as screening particle size, settling particle size, equivalent volume particle size, and equivalent surface area particle size. Sieve size refers to the size of the sieve holes through which particles can pass through the sieve, expressed as the number of sieve holes within a 1-inch (25.4mm) wide sieve. Therefore, it is called "mesh size". Currently, there is no unified technical standard for powder particle size at home and abroad, and each enterprise has its own definition and representation method for particle size. The specifications of screens in different countries and industries have different standards, so the meaning of "mesh" is also difficult to unify.

5. At present, the calculation diameter of equivalent volume particles is commonly used internationally to represent particle size. with μ Represented by m or mm.

6. The customer specifies the number of mesh sizes and has strict requirements or industry requirements that must comply with international standards. Customers are required to specify the corresponding mesh size. The mesh size is the only standard, but there are multiple options for mesh size.

Due to the inconsistency in the mesh size and aperture of the screening machine, users should choose the screening mesh based on the characteristics of their own materials. There is nothing absolute about choosing a sieve, we can only say that we can make the sieve machine and sieve match perfectly.
