Product Overview

The YKQ Series Circular Vibrating Screen is a multi-deck classification machine designed for aggregate, quarrying and mineral-processing applications. Its exciter generates a circular or near-circular screen-box motion that stratifies the material bed and moves the material along the inclined screen decks.

The current YKQ range includes two-, three- and four-deck configurations with reference capacities of 100–500 t/h and maximum feed sizes of up to 300 mm. The number of decks and screen apertures can be selected according to the required finished-product fractions.

Screen media can be selected according to the material and operating conditions. Available configurations may include woven wire mesh, polyurethane panels or rubber panels, subject to the fixing system of the selected model.

Actual screening performance depends on feed-size distribution, bulk density, moisture, clay content, percentage of near-size particles, screen opening and deck loading. Final model selection should be based on project-specific material and process data.

Key Advantages

Circular Motion for Aggregate Classification

The exciter generates circular or near-circular motion in the inclined screen box. This motion promotes material stratification and forward movement, making the YKQ series suitable for aggregate and mineral size classification.

Multi-Deck Size Separation

Two-, three- and four-deck configurations allow one feed stream to be separated into several product sizes. The required deck arrangement should be selected according to the number of finished fractions and target capacity.

Screen Media Options

Woven wire mesh, polyurethane panels and rubber screen media can be considered according to aperture size, abrasiveness, impact load, moisture and blinding risk. Available media and fixing methods must be confirmed for the selected model.

Reinforced Screen Box

The screen box uses reinforced side plates and cross members designed to withstand repeated dynamic loading. The exact connection and reinforcement arrangement depends on the selected YKQ model.

Spring Isolation Support

Spring supports isolate part of the screen-box vibration from the supporting structure and help maintain stable operation. Spring condition and installation height should be checked regularly to identify fatigue, damage or uneven compression.

Dry and Wet Screening Options

The YKQ series can be configured for dry screening or equipped with spray bars for selected wet-screening applications. Wet-screening suitability depends on material properties, water availability, screen media and downstream slurry-handling requirements.

Working Principle

The electric motor drives the exciter through the specified transmission system. Rotation of the eccentric assembly generates circular or near-circular motion in the inclined screen box. Feed material enters the upper deck through the feed chute and should be distributed across the usable screen width. The screen motion causes the material bed to stratify: smaller particles move toward the screen surface and pass through the apertures, while larger particles remain above the screen and travel toward the discharge end. In a multi-deck configuration, material passing through the upper deck is classified again on the lower decks. A two-deck screen can produce up to three size fractions, a three-deck screen up to four fractions, and a four-deck screen up to five fractions when the corresponding discharge chutes are installed. Screening performance depends on feed uniformity, bed depth, material moisture, screen aperture, vibration settings and the percentage of near-size particles. Overloading one side of the screen or feeding material at a single concentrated point can reduce usable screening area and classification efficiency.

Frequently Asked Questions

A circular vibrating screen uses circular or near-circular screen-box motion and is commonly installed on an inclined deck. A linear vibrating screen uses directional linear motion to convey and classify material. Selection depends on feed size, capacity, material characteristics and process position.

Capacity depends on screen size, mesh opening, and material characteristics. Single-deck models typically handle 100–500 t/h, while larger models with wider decks reach up to 1,000 t/h. Circular vibrating screens are available in single-deck, double-deck, and triple-deck configurations, allowing simultaneous separation into 2, 3, or 4 size fractions in a single pass — reducing equipment footprint and investment cost.

We supply a full range of screen media, including woven wire mesh (square or rectangular openings), polyurethane panels, and rubber screen panels. Mesh openings range from 0.5mm to 150mm depending on the application. Polyurethane and rubber panels are recommended for wet, abrasive, or high-impact applications as they offer 3–5 times longer service life than woven wire mesh under the same conditions.

Screen blinding (where particles clog the mesh openings) and pegging (where near-size particles wedge into openings) are common challenges with fine or moist materials. Effective solutions include: using rubber or polyurethane screen panels that flex under vibration to self-clean, selecting a larger mesh aperture relative to feed particle size, adding spray bars for wet screening to flush particles through, or switching to high-frequency electromagnetic screening for very fine or difficult materials.
