Working Principle of Circular Vibrating Screen

Circular vibrating screen is mainly due to the exciter unbalanced heavy wheel rotation, produce radial changes in the centrifugal inertia force (excitation force), drive the screen box, so that the sieve produces vibration of a kind of screening machinery. The trajectory of the sieve frame is elliptical. The material on the screen is thrown up by the force of the upward movement of the screen surface, and then falls back to the screen surface after advancing for a certain distance. This is repeated, and the screening is completed in the process of moving from the feeding end to the discharging end. The amplitude of the vibrating screen can be adjusted by changing the weight and position of the counterweight.

Advantageous features of Circular Vibrating Screen

• Advanced structure, reliable operation:Circular vibrating screen structure adopts cylinder type exciter and bias block adjustment device, advanced riveted connection assembly frame structure improves the service life of the equipment, spring vibration damping device small impact on the foundation, in normal use, the work of the failure rate is small.
• High screening efficiency:Due to the strong vibration of the screen box, it reduces the phenomenon of material blocking the screen holes, so that the screen has a high screening efficiency and productivity.
• Sturdy and durable parts:The side plate of the circular vibrating screen adopts the whole plate cold work, no welding, high strength and long service life; the connection between the crossbeam and the side plate adopts anti-torsion and shear high-strength bolts, no welding, crossbeam is easy to replace.
• Long service life of motor:The transmission part of the equipment increases the middle transition bearing seat, and the application of the middle transition bearing seat effectively protects the motor and prolongs the service life of the motor.

Circular Vibrating Screen FAQ

Q: What is a circular vibrating screen used for?
A: It is used to separate materials by particle size in industries like mining, quarrying, aggregate production, and recycling. It can screen sand, gravel, crushed stone, coal, ore, and many other bulk materials.

Q: How does a circular vibrating screen work?
A: An eccentric weight assembly mounted on the screen box creates a circular throwing motion. The material moves across the screen deck in a circular trajectory, with smaller particles falling through the openings while larger particles discharge at the end.

Q: What are the main advantages of a circular vibrating screen?
A: It offers high screening efficiency, low maintenance cost, simple structure, and reliable operation. The circular motion also helps prevent material clogging and works well for sticky or wet materials.

Q: What size material can a circular vibrating screen handle?
A: Feed sizes typically range from 0 to 400mm depending on the model. Screening mesh sizes can be as fine as 0.5mm or as coarse as 200mm based on your application.

Q: How many decks can a circular vibrating screen have?
A: It can have 1 to 4 decks. Each additional deck allows you to separate the feed material into more size fractions. For example, a 3-deck screen can produce 4 different sized products.

Q: What is the difference between a circular vibrating screen and a linear vibrating screen?
A: A circular screen uses circular motion and is better for wet or sticky materials. A linear screen uses straight-line motion and is typically used for dewatering or classifying dry, free-flowing materials at higher capacities.

Q: How do I choose the right circular vibrating screen size?
A: You need to consider your required processing capacity (tons per hour), feed material characteristics (density, moisture, particle shape), desired cut size, and available floor space. We can help you select the correct model based on these factors.

Q: What maintenance does a circular vibrating screen require?
A: Regular maintenance includes checking and replacing worn screen mesh, lubricating bearings, inspecting springs and rubber mounts, tightening loose bolts, and monitoring vibration motor or exciter condition. Most tasks can be done during scheduled downtime.

Q: Can a circular vibrating screen work with wet materials?
A: Yes, it handles wet and sticky materials very well. The circular motion creates a self-cleaning effect that reduces clogging. For very wet applications, you can also add spray pipes for washing.

Q: How long do screen meshes typically last?
A: Screen mesh life depends on material abrasiveness, feed size, and operating hours. For moderate applications, mesh may last 2-6 months. For highly abrasive materials like granite or basalt, you may need more frequent replacement or use wear-resistant polyurethane or rubber screens.

Q: Do you offer customized circular vibrating screens?
A: Yes. We can customize screen deck size, number of decks, mesh type (woven wire, polyurethane, or rubber), drive motor power, and even material of construction (mild steel or stainless steel) based on your specific application.

Q: What is the warranty on a circular vibrating screen?
A: We typically offer a 12-month warranty covering manufacturing defects and premature component failure. Technical support and spare parts availability continue for the lifetime of the machine.

Q: How long does delivery and installation take?
A: Standard models are typically delivered within 15-25 working days after order confirmation. Installation takes 1-3 days with our engineer on site, including commissioning and operator training.

Q: Do you provide spare parts for circular vibrating screens?
A: Yes, we stock and supply all spare parts including screen mesh, eccentric blocks, bearings, springs, rubber buffers, V-belts, and motors. We recommend keeping certain wear parts in stock to minimize downtime.

Q: Can I see a circular vibrating screen working before buying?
A: Yes. We can provide working videos of similar models or arrange a factory demonstration with your material sample. You are also welcome to visit our factory or existing customer sites.
