AURY Vibrating Screen is a commonly used screening equipment, widely used in chemical industry, coal mine, metal mine and other industries. Its main structure includes screen frame, screen mesh, base, spring and other components. The material selection of different components will also affect the screening effect. The following are the commonly used materials and characteristics of vibrating screens:
★Screen frame material selection
The screen frame of the vibrating screen is generally made of steel or stainless steel. The stainless steel screen frame has better corrosion resistance and is more suitable for handling moist materials. At the same time, stainless steel materials can better meet the clean and hygienic requirements of food, medicine and other industries, making them safer and more reliable to use.
★Screen material selection
The mesh of the vibrating screen is usually made of different materials such as metal mesh, rubber balls, and nylon mesh. The metal mesh has high strength and is suitable for screening coarse-grained materials; the rubber ball requires low-frequency vibration to complete the screening work and is suitable for screening materials with strong viscosity; the nylon mesh has a regular sieve shape and high screening accuracy , suitable for industries that require higher screening accuracy.
★Spring material selection
The springs of vibrating screens are generally made of high-quality spring steel. This material has good elasticity and fatigue resistance and can withstand repeated pressure and tension, ensuring the normal operation of the vibrating screen.
When selecting vibrating screen materials, it is necessary to make a reasonable selection based on specific screening working conditions and material characteristics. For materials with strong viscosity, materials such as nylon mesh or rubber balls should be selected to avoid clogging of the screen. For coarse-grained materials, you can choose stronger materials such as metal mesh, which can better withstand the impact and pressure of the materials.
In addition, the service life of the vibrating screen is also related to the quality of the material. Materials with good quality and good wear resistance should be selected to avoid frequent replacement and maintenance and improve screening efficiency.
AURY Vibrating screens are rich in types and widely used. No matter what kind of screening equipment, the screen plate is an indispensable part. It is in direct contact with the material and will inevitably be worn, so it is not acceptable if it is not wear-resistant. The structure, performance characteristics and selection principles of several vibrating screen plates that are currently relatively mature in production and use are analyzed for your reference.
★Common materials for vibrating screens
âœAURY Stainless steel: Stainless steel is a high-quality vibrating screen material with the characteristics of corrosion resistance, high temperature resistance, and high tensile strength.
✬Polyethylene: The vibrating screen made of polyethylene has a smooth surface and is not easy to adhere to materials and is not easy to gelatinize when exposed to water. The polyethylene mesh has uniform size and good screening effect, and is more suitable for screening materials such as light powder or granules.
✬AURY Polyurethane: The all-polyurethane screen plate is welded by a flat steel frame. The frame tooling is a difficult design problem. It is a new carefully selected product and has gradually replaced the stainless steel screen plate in recent years. The all-polyurethane screen plate is mainly suitable for grading, dehydration, screening and other places in coal mines, iron mines, copper mines, gold mines and other places. It is a necessary component of the vibrating screen.
Since the use conditions of the screen plate are very harsh and require resistance to corrosion, wear and aging, the screen gap size needs to be small enough when used.
✬Advantages: Polyurethane has high wear resistance, high elasticity, sound absorption, shock absorption, not easy to run rough, good wear resistance, long service life, high screening quality, strong self-cleaning ability, good screen penetration performance, reduced noise, improved operating environment, Wide range of application, etc.
✬Selection principle: dehydration, demediation and desliming of various linear vibrating screens.
✬Expanded steel mesh: Expanded steel mesh is generally used for screening materials with higher hardness. Its main features are high surface hardness, not easy to deform, and good wear resistance.
★Suggestions for selecting vibrating screen materials for different materials
✬When used to screen materials with small particles, easy to adhere, and easy to wear, it is recommended to choose 304 stainless steel screens.
✬For materials with high requirements for high temperature resistance, such as coke, refractory materials, etc., you should choose 316 or 316L stainless steel screens.
✬When used to screen heavy powder, pellets, ash and other materials, it is recommended to choose polyurethane vibrating screen, which has greater tensile strength and better wear resistance.
✬For flammable and explosive materials, it is recommended to use steel mesh for screening. It has high surface hardness, higher safety, and is more suitable for screening harder materials.
In short, the selection of vibrating screen material should be comprehensively considered based on the characteristics of the material and the purpose of screening, so as to better ensure production efficiency and finished product quality.
