YA Series Oil Lubricated Circular Vibrating Screen – Product Overview

The YA series oil-lubricated circular vibrating screen delivers high-capacity classification for heavy, medium, and fine screening in mining, aggregate, and recycling circuits.

Oil-Bath Exciter System: Features a precision-forged steel eccentric through-shaft with continuous oil lubrication, keeping bearing temperature rise below 40°C. A large oil reservoir extends maintenance intervals to 1,000–1,500 hours.
Weld-Free Bolted Side Plates: CNC laser-cut side plates connected via high-strength torsion shear bolts eliminate internal welding stress, preventing structural fatigue and plate cracking under heavy vibration.
Adjustable Excitation Force: An external eccentric block design generates powerful centrifugal force, allowing operators to easily tune amplitude using counterweights to optimize screening efficiency.
Heavy-Duty Rigid Frame: Designed with generous deck spacing for rapid screen mesh replacement, supported by heavy compression springs that disperse dynamic loads to extend machine service life.

What is the working principle of the YA Series Oil Lubricated Circular Vibrating Screen?

◎The YA series circular vibrating screen operates on circular motion vibration generated by an eccentric shaft exciter. The motor drives the exciter through V-belts, causing the eccentric shaft to rotate at high speed and create centrifugal force, which generates full-range circular vibrating motion of the screen box.

◎The exciter features a through-shaft design with external block eccentric structure. As the eccentric shaft rotates, counterweight blocks produce unbalanced centrifugal forces that drive the screen box in a circular trajectory. Amplitude can be easily adjusted by adding or removing counterweight blocks to suit different materials and screening requirements.

◎Vibration is transmitted evenly to the screen box through precisely machined exciter mounting holes. Material fed onto the screen deck moves along the surface in a circular path, allowing smaller particles to pass through openings while larger particles travel to the discharge end.

◎The oil lubrication system maintains bearing temperature rise below 40°C. Oil changes are required only every 1000-1500 hours, significantly lowering maintenance costs. Abrasion-resistant guards prevent oil chamber wear, extending service life.

◎The screen box uses high-strength torsion shear bolts for reliability under tough conditions. Fixed integral spring supports provide rigidity while dispersing stress. Wear-resistant liners protect feed and discharge chutes. Material is continuously fed, screened, and discharged, enabling efficient screening for aggregates, mining, coal, chemical, and recycling applications.

Common Problems

This section is designed to address the most pressing inquiries customers may have regarding the daily operation, maintenance, product advantages, and after-sales service of our machine. Our aim is to help you gain a comprehensive understanding of our overall capabilities and enable you to make informed decisions for your projects.

The YA series uses a maintenance-free oil lubrication system. The large-capacity oil tank keeps bearing temperatures low, requiring oil changes only every 1000-1500 hours, which significantly reduces maintenance costs.

The exciter features an external block eccentric design. Amplitude can be easily adjusted by adding or removing standard counterweight blocks, allowing operators to adapt to different material characteristics and screening requirements.

Side plates are CNC laser-cut with no weld points, eliminating welding stress. All structural connections use high-strength torsion shear bolts for superior reliability under tough conditions. Cross beam ends are machined as a whole to ensure shape tolerance.

Yes. The screen features large deck spacing that facilitates convenient screen replacement and maintenance. The modular design and accessible components allow quick parts replacement, minimizing downtime and production loss.

The YA series is suitable for heavy, medium, and fine screening applications, widely used in aggregates, metal mining, coal, chemical, and recycling industries.

The bearing temperature rise is kept below 40°C during operation. This is achieved through the large-capacity oil tank and efficient lubrication system, which effectively reduces bearing operating temperatures, extends bearing service life, and ensures reliable long-term operation.

The through-shaft exciter design eliminates intermediate transmission and protective structures, reducing the number of transmission components. This significantly improves the stability of the vibrating screen, reduces potential failure points, and ensures more reliable performance under continuous heavy-duty operation.

The exciter mounting holes on both side plates are machined using high-precision CNC boring and milling equipment. This ensures excellent coaxiality and parallelism between the mounting holes, guaranteeing proper exciter alignment, smooth vibration transmission, and reduced stress on the screen box for extended service life.
