3YK1545 Circular Vibrating Screen - High-Efficiency Multi-Deck Aggregate Screening

In '3YK', the '3' indicates that the screen has three deck layers, and 'YK' is the pinyin abbreviation for 'Circular Vibrating Screen' (Yuan Zhen Dong Shai). The '1545' represents the effective screen width of 1500 mm and effective screen length of 4500 mm. Therefore, the 3YK1545 is a triple-deck circular vibrating screen with a screen surface measuring 1500×4500 mm, capable of separating a mixed feed into four sized fractions in a single pass.

A circular vibrating screen produces a near-circular or elliptical vibration trajectory, causing material to tumble and loosen on the screen surface — excellent for preventing blinding and ideal for high-tonnage coarse classification of moist, clay-bearing, or difficult-to-screen materials. A linear vibrating screen produces a straight-line reciprocating motion, suitable for fine material dewatering, desliming, and medium removal where precise sizing is critical. For closed-circuit screening in mining and aggregate production lines, circular vibrating screens are the dominant choice.

Aperture selection depends on your required final product specifications. For a typical granite aggregate line, a common three-deck configuration is: top deck 30 mm (intercepts >30 mm oversize for recrushing), middle deck 20 mm (produces 20-30 mm large stone), bottom deck 10 mm (produces 10-20 mm coarse aggregate), with undersize being 0-10 mm mixed sand and fines. We can provide customized aperture configurations based on your specific product gradation requirements.

Polyurethane panels offer superior wear resistance, corrosion resistance, and noise reduction, typically lasting 3-5 times longer than wire mesh, and are less prone to blinding — ideal for moist and clay-bearing materials. Their drawbacks are lower open area ratio and higher cost. Woven wire mesh has higher open area, better screening efficiency, and lower cost, suitable for dry, coarse, hard-rock materials, but wears faster. For most aggregate lines, we recommend a hybrid approach: wire mesh on the top coarse deck and polyurethane on the middle and bottom fine decks, balancing efficiency and service life.

Screen inclination directly affects material travel speed and retention time on the screen surface. A steeper angle increases material velocity and throughput but reduces screening precision; a shallower angle extends material retention time and improves accuracy but reduces capacity. The standard installation angle for the 3YK1545 is 15° to 25°, with 20° recommended as a starting point. If strict product sizing is required, reduce the angle to 15°-18°; if maximizing throughput is the priority with relaxed precision requirements, increase to 22°-25°.

Blinding is a common screening challenge. Address it from several angles: first, check material moisture and clay content — consider adding a wash or pre-desliming stage upstream if necessary; second, adjust the screen inclination — a steeper angle enhances material self-cleaning action; third, switch to anti-blinding polyurethane panels whose elastic deformation helps prevent pegging; fourth, verify that excitation force is adequate — increasing the eccentric block angle can boost throwing intensity. For extreme conditions, we offer customized solutions with ultrasonic cleaning systems or bouncing ball anti-blinding devices.
