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. .
