Product Overview
A circular-motion vibrating screen is a high-precision, multi-layer industrial screening machine designed for particle classification, impurity removal, and bulk material sieving. Adopting circular orbital vibration motion, this circular vibrating screen features stable vibration amplitude, large processing capacity, and non-blocking screening performance. Widely applied in mining, ore, chemical, metallurgy, construction materials, and grain industries, the circular vibrating screen effectively separates powders, granules, and granular mixtures according to different particle sizes. As reliable industrial screening equipment, it solves common production pain points such as uneven grading, low output, and screen clogging during material processing.
Core Features & Advantages
- High Screening Accuracy & Large Output: Stable circular vibration ensures full material dispersion and stratification, greatly improving screening precision and single-machine processing capacity, avoiding material mixing and incomplete separation.
- Reduced Screen‑clogging Tendency: The circular rolling motion helps reduce fine particles sticking to screen openings, easing screen hole blockage for most granular materials. (Not suitable for heavily sticky fine powder).
- Optional Dust‑proof Cover: Dust‑proof cover is available as option to minimize material dust overflow, meeting industrial environmental protection standards and improving workshop working environment.
- Stable Operation & Low Noise: Optimized vibration structure and balanced eccentric design ensure smooth operation, low running noise, and long continuous working time.
- Flexible Multi-layer Classification: Support customized 1–3 screen layers, flexible discharge ports design, meeting multi-grade particle screening and grading requirements.
- Durable & Low Maintenance: Thickened screen frame and high-strength screen mesh feature strong wear resistance and long service life; simple structure with few vulnerable parts reduces later maintenance costs.
Working Principle
The circular-motion vibrating screen relies on a vibration motor with eccentric blocks as the vibration source. After power-on, the eccentric blocks rotate at high speed to generate centrifugal excitation force, driving the screen box to produce regular circular orbital vibration. After materials evenly fall onto the screen surface from the feeding port, they continuously roll, jump and disperse under circular vibration force. Due to different particle sizes, fine particles pass through the screen mesh and fall to the lower layer, while large-particle materials stay on the screen surface and move toward the discharge port. Multi-layer screen meshes with different apertures realize automatic classification of materials of various particle sizes, finally completing precise screening and grading operations.

➤ Torsion-free screen frame
➤ Custom‑designed solution available: screen opening size can be adjusted as required, with optional screen media in PU or stainless steel.
➤ Reasonable vibration parameters avoid the natural frequencies of the sieve body and reduce the resonance effect
➤ The side panels and stiffeners are riveted with HUCK bolts, avoiding weaknesses or tensions in the metal that may be caused by welding, improving the strength and rigidity of the side panels and the reliability of the equipment
➤ Box beam construction is adopted on the girder of the exciter and the cross beam of the screen frame. The internal stiffeners enhance the rigidity and strength of the screen and lighten up the machine, so as to improve the efficiency and reduce the power consumption
➤ The girder of exciter and the cross beam are annealed to eliminate the stress after welding.
Machining between sections of girders and side panels
➤ Long life-time ( screen frame up to 5 years, drive up to more than 15,000 hours)
Application Industries & Materials
Circular‑motion vibrating screen (YK series) adopts single‑shaft block‑eccentric exciter. With excellent material tumbling performance and screen deck self‑cleaning effect, it is mainly designed for dry classification of medium‑coarse bulk materials.
It is widely used in aggregate & quarry plants, mineral processing plants, coal industry, building‑material & metallurgy, solid‑waste recycling, power and chemical industries. Typical processed materials include crushed stone, granite, basalt, river pebble, iron ore, copper ore, raw coal, clinker, steel slag and other bulk minerals.
Available in single‑deck, double‑deck and triple‑deck configurations. Customization is supported according to required capacity, screening area and screen opening size, to fit closed‑circuit crushing, pre‑screening and finished‑product grading processes.
F-A-Q
Q: What is the difference between a circular vibrating screen and a linear vibrating screen?A: Circular vibrating screens adopt circular orbital vibration with higher screening accuracy, suitable for fine powder and granular materials; linear vibrating screens use straight vibration with larger output, more suitable for coarse material grading and large-volume production.
Q: How to solve screen clogging of circular vibrating screen?
A: Equipped with bouncing ball anti-blocking device, combined with continuous circular rolling vibration, which effectively prevents material adhesion and screen hole blockage.
Q: Is the circular‑motion vibrating screen suitable for food‑grade material processing?
A: Yes for coarse pre‑treatment. VRV can customize it with full 304/316 stainless steel for material‑contact parts. It is applicable for washing & sizing of large‑size food granules. Not recommended for fine powder and high‑hygiene fine‑grade production.
Q: What particle size range can the circular‑motion vibrating screen sieve?
A: It is designed for medium‑coarse materials, working for particle sizes from 3 mm up to 100 mm. It delivers high‑capacity multi‑grade classification for granular and lump materials.
