The impurities mixed in mung beans are generally stones, dust, weeds, etc. If you want to get rid of these impurities, a linear vibrating screen is the first choice for removing these impurities. The main reasons for choosing a linear vibrating screen are the following:

1. The linear vibrating screen has a large output and high efficiency. Generally, the output of the linear vibrating screen can be between 1 and 10 tons per hour. Compared with the rotary vibrating screen, the large output of the linear vibrating screen is more suitable for the needs of manufacturers.
2. The linear vibrating screen has a simple structure and is easy to maintain. For the equipment with simple structure for the production line, if there is a problem, it can be repaired in time, and the fault is checked.
3. The full-closed structure of the linear vibrating screen, the dust will not fly, because there are dust and other impurities in the mung bean, the full-closed structure can prevent the dust from flying in the workshop and protect the clean environment of the workshop.

For screw conveyors used in metallurgy, mining and chemical industries, the shaft end gland is widely sealed with packing. Because the particle size of the coal powder is 200 mesh, it is in the form of fine powder and has a certain fluidity, so it is often because the shaft end of the screw conveyor head is not tightly sealed and many coal powders are leaked. Although asbestos packing, oil-impregnated asbestos rope and flexible graphite ring are also used as sealing packing, the leakage control effect is not ideal. Pulverized coal leaks around the equipment every day, which wastes and pollutes the environment and affects civilized production. In order to solve this problem, the following method hopes to be useful to you.
1.Lubricating grease must be added into the gland every 3-4 days, otherwise the coal powder will still be leaked or the coal powder will leak out
2.After each installation and disassembly, the gland bolts must be tightened for about one month after starting up, so that the packing and the shaft closely fit together. But it is not necessary to press too tightly, the gland bolts can be adjusted according to the actual situation.

The frequency of checking the tension of the vibrating screen's belts will depend on several factors, such as the screen's usage frequency, the load it handles, and the manufacturer's recommendations.

Generally, it is recommended to check the tension of the belts on a regular basis, such as once a month, to ensure that they are properly tensioned and do not show any signs of wear or damage. If you notice any signs of wear, such as cracks, fraying, or stretching, the belts should be replaced immediately to prevent further damage and potential failure.

It's also important to keep in mind that belts can wear out over time due to regular use and exposure to environmental factors. Therefore, even if there are no visible signs of wear, it may be necessary to check the tension of the belts periodically to ensure optimal performance of the vibrating screen. The manufacturer's recommendations regarding belt tensioning and maintenance frequency can also provide guidance on when to check the belt tension.

In addition to regular checks of the belt tension, it's important to maintain proper tension on the belts to ensure that the screen operates smoothly and efficiently. Improperly tensioned belts can cause the screen to vibrate excessively, leading to premature wear and potential damage. Be sure to follow the manufacturer's recommended tensioning procedure to ensure proper operation of the screen.

The manufacturer's recommended tensioning procedure for the vibrating screen's belts will depend on the specific model of the screen and the type of belts being used. However, here are some general guidelines for tensioning the belts:

1. First, ensure that the screen is turned off and disconnected from the power source.

2. Locate the belt tensioner, which is typically a spring-loaded pulley located near the motor.

3. Use a tension gauge or other appropriate tool to measure the tension of the belts.

4. Adjust the tensioner as needed to achieve the manufacturer's recommended tension. This may involve adjusting the tensioner bolt or moving the tensioner pulley to increase or decrease tension.

5. Check the tension of the belts again after making adjustments to ensure that they are within the recommended range.

6. Once the proper tension has been achieved, tighten the tensioner bolts or lock nuts to secure the tensioner in place.

7. Verify that the screen is operating smoothly and efficiently before resuming use.

It's important to note that these are general guidelines, and the specific tensioning procedure may vary depending on the model of the vibrating screen and the manufacturer's recommendations. Always refer to the user manual or contact the manufacturer for specific instructions and recommendations.

1. Use a reasonable inclination angle to control the flow speed of the material on the screen surface. Generally speaking, the material on the sieve surface with a large inclination angle has a fast movement speed and a large production capacity, but the efficiency is low. In order to obtain higher screening efficiency, the moving speed of materials on the screen surface is generally controlled below 0.6m/S, so the screen surface should be kept at 15. Left and right inclination.

2. Increase the screening area. Screening practice has proved that reducing the amount of material on a unit screen surface can improve screening efficiency. When the actual amount of material on the sieve surface is about 80% of the sieve capacity, the sieve screening efficiency is the highest. When sieves are used as grading equipment, due to the large number of fine-grained grades, sufficient sieving area and appropriate lengthening of the sieve surface should be ensured, so that the aspect ratio is above 2:1, which is conducive to improving the screening efficiency.

3. Use a large size sieve. The large-scale circular vibrating screen increases the vibration force and amplitude, which increases the impact stress and shear stress of the screen plate on the material to overcome the adhesion between the ore particles, and also reduces the blockage of the screen surface, so that the screened material can be quickly loosened. , layering and sieving. Due to the improvement of the operating conditions of the sieve, the screening efficiency is improved.

4. Adopt a multi-layer sieve with enlarged sieve holes. "Difficult to sieve particles" and "obstructed particles" (particles larger than sieve holes) in the feed of ordinary single-layer sieves almost all move from the feed end to the discharge end, thus affecting the stratification and sieving of medium and fine-grained materials. The multi-layer sieve adopts a multi-layer sieve that gradually increases the sieve openings from the lower layer to the upper layer and gradually decreases the inclination angle of the screen surface. That is to say, for materials with different particle sizes, screen surfaces with different inclination angles and screen holes are used, and the materials are loosened, layered, pre-screened and fine-grained screened on the upper, middle and lower screen surfaces respectively, so as to overcome the blockage of the screen holes and improve the quality of the screen. Screening efficiency.

5. Adopt equal thickness screening method. As the screening process proceeds, the thickness of the material on the screen surface gradually becomes thinner from the feeding end to the discharge end, resulting in an unreasonable feeding phenomenon that the screen surface is first tightened and then loosened. Therefore, broken line screen surfaces with different inclination angles can be used. , to control the different moving speeds of the materials in each section of the screen surface, so that the ore flow slopes forward, thereby improving the chance of passing through the screen of the difficult-to-screen particles at the discharge end

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. .
