circular plastic vibro screen, plastic vibrating screen
A circular plastic vibro screen is a kind of screening equipment that uses a vibrating motor to drive a circular plastic screen frame to vibrate, so as to screen and filter materials. It is also known as a plastic vibrating screen or an anti-corrosion vibrating screen. Here is a detailed introduction:
Structure and Principle of circular plastic vibro screen
Structure: It is mainly composed of a plastic screen frame, a vibrating motor, a screen mesh, and a supporting device. The screen frame is usually made of corrosion-resistant plastic materials such as polypropylene, and the screen mesh can be selected according to the screening requirements.
Principle: The vibrating motor generates vibrations, which are transmitted to the screen frame through the vibration damping device. The screen frame drives the screen mesh to vibrate, so that the materials on the screen mesh are screened and classified under the action of vibration force. The fine materials pass through the screen mesh, and the coarse materials are discharged from the discharge port.
Specifications of circular plastic vibro screen
Common specifications include diameters of 400mm, 600mm, 800mm, 1000mm, 1200mm, etc. The number of screen layers can be 1-5 layers, and the motor power is generally 0.18-2.2KW.
Characteristics of circular plastic vibro screen
Corrosion Resistance: Due to the use of plastic materials, it has excellent corrosion resistance and is suitable for screening and filtering corrosive materials such as chemical powders and acidic liquids.
Fine Screening: It can achieve fine screening of materials, and the screening accuracy can reach 500 mesh (0.028 mm).
High Efficiency: The vibration force can make the materials on the screen mesh move continuously, which improves the screening efficiency and can handle a large amount of materials in a short time.
Simple Operation and Maintenance: The structure is simple, the operation is convenient, and the maintenance is easy. The screen mesh is easy to replace, which reduces the maintenance cost and downtime.
Applications of circular plastic vibro screen
Food Industry: It is used for screening and filtering flour, sugar, salt, spices, and other food materials to remove impurities and ensure the quality of food.
Chemical Industry: It is suitable for screening and filtering chemical powders, resins, paints, and other materials to separate different particle sizes and remove oversize particles.
Pharmaceutical Industry: It is used for screening and filtering pharmaceutical powders, granules, and other materials to ensure the uniformity and purity of pharmaceutical products.
Other Industries: It can also be used in industries such as ceramics, metallurgy, and mining for screening and filtering related materials.
Key Advantages of circular plastic vibro screen
-
Strong Corrosion Resistance
The screen frame is mainly made of corrosion-resistant plastics such as polypropylene. It can resist the erosion of acidic, alkaline, or chemical corrosive materials, avoiding rust or material contamination that may occur with metal screens.
-
High Screening Precision & Efficiency
Driven by a vibrating motor, the screen mesh produces stable and directional vibration. This ensures materials are fully dispersed and screened, with precision reaching up to 500 mesh (0.028 mm). At the same time, continuous vibration prevents material blockage, maintaining high processing efficiency.
-
Low Cost & Easy Maintenance
The overall structure is simple, and the plastic parts are lightweight. Replacing vulnerable parts like the screen mesh is quick and does not require complex tools. Compared with metal screens, it has lower manufacturing and maintenance costs, and shorter downtime.
-
Good Material Compatibility
The smooth surface of plastic materials does not easily adhere to materials, especially for sticky powders or liquids. This reduces material waste and ensures the purity of the screened products, which is crucial for the food and pharmaceutical industries.
