Linear Vibrating Screen
Share to:
The linear vibrating screen uses a vibrating motor as the vibration source. The motor’s dual eccentric blocks rotate to generate vibrational force, causing the screen body to move back and forth in a linear direction (typically horizontal or at a small angle). Material enters through the feed opening and, under the vibration of the screen surface, is layered according to particle size. Fine particles pass through the screen mesh to the lower layer or are discharged as undersize material, while coarse particles move along the screen surface to the discharge opening for removal, thereby achieving screening, de-contamination, and grading functions.
Machine Overview and Functional Description
The screen body is typically made of stainless steel, which offers corrosion resistance and ease of cleaning, though carbon steel is also available to suit different operating conditions. It includes the screen frame and screen mesh. The screen frame provides structural support for screening and ensures stable vibration. The screen mesh is the core screening component, available in types such as metal wire woven mesh or perforated plates. The mesh aperture size can be selected based on material particle size requirements to achieve precise screening. The vibrating motor serves as the primary vibration source, typically symmetrically mounted on both sides of the screen body. By adjusting the angle and weight of the eccentric blocks, the magnitude and direction of the vibrating force can be modified to accommodate different material screening rhythms. The vibration damping system uses vibration damping springs to buffer vibration transmission, reduce the impact of equipment vibration on the foundation, ensure stable vibration of the screen body, and extend the service life of the equipment and surrounding facilities. The feed opening is typically located at the top of one end of the screen body to ensure uniform material entry. The discharge openings are distributed at the other end and sides of the screen body, with the number adjustable as needed to achieve discharge of materials with different particle sizes.
Application Areas and Suitable Materials
Application Scenarios
Food industry: Used for grain (such as wheat, rice) impurity removal and screening, removing stones, straw, and other impurities; in fruit and vegetable processing, for grading fruit and vegetable particles (such as screening different-sized fruit pieces for canned food production); also used for screening powdered materials like flour and starch, ensuring uniform product particle size.
Chemical Industry: Processing plastic pellets, resin powders, etc., to achieve coarse and fine grading, such as screening plastic pellets of different particle sizes after granulation to ensure product quality stability; in paint production, screening pigment and filler particles to remove lumps and impurities.

FAQs
- Can this linear screen be used for materials such as moist or easily clogging materials? Is the screening effect guaranteed?
The linear screen can handle most materials, but moist or highly adhesive materials are prone to clogging. If your material is special, we recommend providing material characteristics (humidity, particle size, adhesion, etc.), and we can customize a solution: opting for a screen cleaning device (such as bouncing balls or ultrasonic screen cleaning), or adjusting the screen angle and vibration parameters (increasing amplitude to prevent buildup) to ensure screening efficiency.
- Can the equipment’s production capacity match my production line? How do I choose the appropriate model?
Production capacity is determined by screen size, number of layers, and vibration parameters. You need to provide the hourly processing capacity and particle size requirements before and after screening, and we will recommend a suitable model to ensure it aligns with your production line rhythm.
- How much does the equipment cost? Is maintenance expensive? What are the wear parts?
Answer: The price is influenced by the model (screen surface size, number of layers), material (stainless steel/carbon steel), and configuration (standard motor/explosion-proof motor), ranging from several thousand to several ten thousand. The main wear parts are the screen mesh and vibration springs. The motor and frame are durable and only require regular maintenance. We provide a price list for wear parts and can also guide you in replacing them yourself to reduce costs.
- Is installation and commissioning complicated? Do you offer installation services? How are post-installation issues resolved?
Answer: Installation follows a standard process (securing the frame, connecting the vibration source, and leveling). We provide an installation manual and video guidance.
- What are the available shipping methods?
Common shipping methods include sea freight, air freight, and land freight. You should select the appropriate method based on the nature of the goods, quantity, and delivery date.
