Vibrating screen spare parts mainly consist of four major parts: excitation system, load-bearing system, screening system, and support system. The specific configuration of different types of vibrating screens (linear, circular, high-frequency, etc.) varies slightly, but the basic framework is basically the same.

Vibrating Screen Spare Parts Components

Below is the functional introduction of key components:

Excitation System

Vibration motor (most common): generates centrifugal force by rotating eccentric blocks, driving the screen body to vibrate. It needs to match the equipment power to ensure uniform material dispersion.
Exciter: includes eccentric blocks, bearings, transmission shafts, etc., and can adjust the excitation force by adjusting the eccentric block angle.
Ultrasonic system (ultrasonic vibrating screen): composed of ultrasonic generator and transducer, superimposes high-frequency vibration (20-40KHz) to solve the problem of fine powder blocking the screen.

Screening main frame: Load-bearing system

Screen box: welded or bolted from steel plates, requiring high strength and rigidity to withstand vibration impact.
Screen frame: the structure that supports the screen mesh, made of pine wood (traditional) or metal material, and needs to keep the screen mesh flat and tight.
Crossbeam: connects the side plates of the screen box, enhances overall stability, and is mostly made of seamless steel pipe or section steel.

Screening System: Vibrating Screen Spare Parts

The screen mesh is the key component of vibrating screen spare parts that directly contacts the material. The most common materials are:

Metal: stainless steel, carbon steel (wear-resistant)
Non-metal: polyurethane, nylon (acid and alkali resistant)
Special: ultrasonic screen mesh (fine screening)
Screen plate: perforated plate, woven mesh, slotted screen, etc., selected according to material characteristics.

Vibration reduction and stability: Support system

Vibration damping spring: commonly used rubber springs or coil springs to reduce vibration transmission to the ground and reduce noise.
Support/base: supports the entire equipment, and must ensure level installation to avoid eccentric load.
Isolation device: high-end models adopt air springs or composite shock absorbers to further reduce dynamic load.

Auxiliary accessories

Cleaning device: bouncing balls, ultrasonic, brushes, etc., to prevent material blocking the screen.
Sealing structure: dust cover, rubber sealing strips, suitable for occasions with large dust or high hygiene requirements.
Lubrication system: automatic grease injection device to extend bearing life.

Key differences:

Linear vibrating screen: two motors rotate synchronously in opposite directions, and the trajectory is a straight line.
Circular vibrating screen: driven by a single motor, the trajectory is circular or elliptical.
Ultrasonic vibrating screen: vibration frequency is above 3000 times/min, suitable for fine materials.

Rotary Vibrating Screen

Ultrasonic Vibrating Screen

Maintenance focus:

Check the screen mesh tension daily to prevent material leakage.
Replace motor grease after a total running time of 2000 hours.
Regularly check whether the damping springs are cracked and whether the support bolts are loose.
Vibrating screens in different industries will optimize component materials and structures according to material characteristics (such as corrosiveness, viscosity, particle size).

For example, the food and pharmaceutical industries mostly use stainless steel materials, while the mining industry requires heavy-duty design.

FAQs

Q1: What are the main vibrating screen spare parts?

A1: Vibrating screen spare parts mainly include the excitation system load bearing system screening system and support system. The excitation system contains vibration motor exciter and ultrasonic system. The load bearing system includes screen box screen frame and crossbeam. The screening system includes screen mesh screen plate and cleaning device. The support system includes springs base and vibration isolation devices.

Q2: What is included in vibrating screen spare parts components?

A2: Vibrating screen spare parts components cover all parts that make the vibrating screen work normally. Common components are vibration motor eccentric block exciter bearings screen mesh polyurethane screen and rubber springs. These components are the core parts for industrial vibrating screen spare parts replacement and spare parts supply.

Q3: How often should vibrating screen spare parts be maintained?

A3: Maintenance of vibrating screen spare parts should include daily inspection of screen mesh tension and regular checking of springs and bolts. For example after running 2000 hours the vibration motor lubrication grease should be replaced. Regular maintenance helps prevent common failures such as spring cracking screen mesh leakage and motor overheating.

Q4: What are the differences between vibrating screen spare parts for different industries?

A4: Different industries require different vibrating screen spare parts materials and structures. Food and pharmaceutical vibrating screen spare parts usually use full stainless steel and strict sealing. Mining and quarry vibrating screen spare parts need a heavy-duty design thicker screen box and more wear resistant screen mesh. Choosing the right parts depends on material corrosiveness viscosity and particle size.

Q5: Where can I buy vibrating screen spare parts replacement in China?

A5: If you need vibrating screen spare parts replacement or custom spare parts supply you can contact Sanyuangtang Machinery. We have 30 years of vibrating screening manufacturing experience and can provide industrial vibrating screen spare parts solutions for different applications and regions.

Q6: What is the best way to avoid screen mesh blockage in vibrating screen spare parts?

A6: To avoid screen mesh blockage in vibrating screen spare parts the key is choosing the correct mesh type and adding cleaning devices. Common solutions include using polyurethane or nylon screen mesh adding bouncing balls or brushes and installing ultrasonic systems for fine powder. Regular maintenance and correct tensioning also help reduce blockage.
