Vibrating screen mesh is a metal mesh structure element used for screening and filtering. It is widely used in screening, filtering, dehydration, desludging and other operations in many industries such as mining, coal mining, construction, glass factories, petroleum, hardware products, food processing, and medicine. It uses vibration waveforms to screen and classify materials on the screen to achieve separation of different particle sizes.

The weaving structure of the vibrating screen is diverse, including bidirectional corrugated bend, locking bend, bidirectional wave separation bend, flat top bend, unidirectional corrugated bend, etc. These structures make the screen strong and durable, able to withstand the huge impact and friction when the vibrating screen is working. The models and specifications of the screen are also diverse, such as flat screen plates, curved screens, etc., to meet the needs of different industries and application scenarios.The correct installation method of the vibrating screen is very important to ensure the screening effect and the service life of the screen.

Vibrating screen mesh installation methods

1. Preliminary preparation

Check the screen: Make sure the screen is not damaged or deformed, and the size matches the screen frame.

Prepare tools: Prepare the tools required for installation, such as bolts, nuts, hooks, wooden wedges, hammers, etc.

Clean the screen frame: Clean the debris and residue on the screen frame to ensure that the surface of the screen frame is clean and free of impurities.

2. Installation steps

Open the dust cover and take out the screen frame: First, you need to open the dust cover of the vibrating screen, and then take out the screen frame that needs to be replaced or installed.

Fix the screen:

Bolt fixation: For screen plates with a thickness greater than 8mm or textile screens with a large screen wire diameter, bolts can be used to fix them directly to the screen frame. Bolts are in the form of U-type and J-type. J-type bolts are more convenient to disassemble, so they are more commonly used.

Hook tensioning: For woven screens or screen plates with a thickness of less than 6mm, the end of the screen or screen plate can be bent into a hook shape, and then fixed with hooks and bolts. In order to effectively tension the screen surface and not produce secondary vibration, the bolts should be designed in a certain angle and elastic washers should be added on the outside.

Slot structure: Some vibrating screens use slot structure to fix the screen plate. This method is easy to disassemble and replace, and is fast. It is suitable for thin steel plate punching screen surface, rubber and polyurethane screen surface for medium material screening.

Wooden wedge pressing: For slit screen plates and screen surfaces of certain specific materials, wooden wedge pressing can be used to fix them. The screen surface is supported between two angle steels and pressed with wooden wedges and wooden strips. The wooden wedge expands when it comes into contact with water, which can press the screen surface very tightly, and it is also very convenient to replace the screen surface.

Adjustment and tightening: After the screen is fixed, its position needs to be adjusted to ensure that the screen is flat and wrinkle-free. Then, tighten the tightening bolts to make the screen frame and the screen fit tightly.

Start-up inspection: After the installation is completed, start the vibrating screen for no-load trial operation to check whether the screen is firmly fixed and whether there is any looseness or abnormal sound. If there is any problem, stop the machine immediately for inspection and adjustment.

3. Precautions

Install strictly according to the manufacturer's requirements or instructions: The installation method of the vibrating screen of different models may be different, so be sure to follow the manufacturer's instructions.

Pay attention to safety: During the installation process, you should pay attention to personal safety, wear protective equipment, and avoid accidents.
Regular inspection and maintenance: The vibrating screen should be inspected and maintained regularly during use, including the wear of the screen and the tightness of the fixing bolts, to ensure the screening effect and the service life of the screen.
4. Application scenarios
Mining: In ore dressing, coal washing and mine waste treatment, the vibrating screen mesh achieves particle size classification of ore and coal through screening to improve the efficiency of ore dressing.

Building materials: In the production process of building materials such as concrete, sandstone and mortar, the vibrating screen mesh is used to separate impurities and particles that do not meet the requirements in the raw materials to improve the quality of building materials.

Chemical industry: In chemical production, the vibrating screen mesh is used for solid-liquid separation, screening of solid particles and classification of particles, such as purification of chemical raw materials, classification of particulate materials and screening of catalysts.

Food processing: In the food processing process, the vibrating screen mesh is used for solid-liquid separation and particle screening, such as screening of food raw materials and removal of impurities, to improve the quality and safety of food.

Medical field: In drug production, the vibrating screen mesh is used for solid-liquid separation and particle screening, such as fine screening of drug raw materials and preparation of tablets.

The installation and maintenance of the vibrating screen mesh is crucial to ensure the screening effect and extend the life of the equipment. During installation, it is necessary to ensure that the screen is flat, tensioned and firmly fixed; during maintenance, the wear of the screen should be checked regularly and the damaged screen should be replaced in time. In addition, it is also necessary to keep the screen clean and dry to prevent material contamination and corrosion.

The vibrating screen mesh is an indispensable and important part of the vibrating screening equipment. Its excellent performance characteristics and wide application scenarios make it play an important role in industrial production. At the same time, reasonable installation and maintenance are also the key to ensure the screening effect and extend the life of the equipment.
