Product Overview

The YKZ Series Linear Vibrating Screen is a heavy-duty screening machine designed for high-capacity classification in aggregate, mining and mineral-processing plants. Synchronized exciters generate a linear vibration trajectory that moves material forward across the screen surface while separating it into the required size fractions.

The listed YKZ models are available with one to four screen decks. Multi-deck configurations allow several product sizes to be produced from one feed stream, while the screen aperture and screen-media material can be selected according to the application.

Selected YKZ models accept feed sizes of up to 400 mm. Reference capacity begins at approximately 180 t/h, while the maximum available capacity must be confirmed according to the selected model and whether the ZXS configurations belong to the YKZ product range.

The actual performance of a linear vibrating screen depends on feed-size distribution, bulk density, moisture content, percentage of near-size particles, screen opening, number of decks and required screening efficiency. XINGAONAI engineers select the machine according to project-specific material and process data.

Key Advantages

Heavy-Duty Linear Screening

The synchronized excitation system produces a directional linear motion that conveys material across the screen decks while promoting particle stratification. This configuration is suitable for high-load classification duties in aggregate and mineral-processing circuits.

Adjustable Excitation Force

The excitation force can be adjusted through the exciter counterweights within the model-specific operating range. This allows the screen motion to be matched to the material load, feed conditions and required classification duty. Adjustments must be made symmetrically and according to the equipment manual.

Multi-Deck Classification

The current YKZ range includes one-, two-, three- and four-deck configurations. A multi-deck linear vibrating screen can separate one feed stream into several product-size fractions, reducing the need for multiple screening machines.

Reinforced Screen Box

The screen box uses reinforced side plates and cross members to withstand repeated dynamic loading. High-strength ring-groove rivet connections are used in critical areas to reduce welding-induced residual stress and improve fatigue resistance.

Rubber Composite Spring Support

Rubber composite springs support the screen box and isolate part of the dynamic load from the supporting structure. Their condition should be inspected regularly to identify uneven deformation, ageing or damage.

Replaceable Screen Media

Screen aperture and media can be selected according to material abrasiveness, moisture, impact load and target product size. Available woven wire mesh, polyurethane or rubber panels should be confirmed for each model and fixing system.

Working Principle

The YKZ Linear Vibrating Screen uses synchronized exciters fitted with eccentric masses. When the exciters operate in coordinated directions, force components perpendicular to the intended vibration direction offset each other, while the force components along the screening direction combine. This causes the screen box to move in a stable linear trajectory. Feed material enters the upper screen deck through the feed chute and is distributed across the usable screen width. The linear vibration throws the material forward and promotes stratification within the material bed. 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 multi-deck configurations, material passing through an upper deck is classified again on the lower decks. Each deck uses the selected aperture to produce the required product fractions. Screening performance depends on uniform feeding, suitable bed depth, material moisture, feed-size distribution, screen aperture, vibration settings and the percentage of near-size particles. Overloading one area of the screen can reduce efficiency even when the total feed rate remains within the listed capacity range.

Frequently Asked Questions

A linear vibrating screen is used to classify bulk materials into specified size fractions. The YKZ series is designed for heavy-duty screening in aggregate, mining, quarrying, coal and mineral-processing plants.

Synchronized exciters generate directional force that causes the screen box to move in a linear trajectory. The motion conveys material forward while smaller particles pass through the screen apertures and larger particles discharge from the end of the deck.

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

The current YKZ model range includes one-, two-, three- and four-deck configurations. More decks allow additional product fractions but may reduce throughput under the same feed conditions.

Please provide the material, maximum feed size, feed gradation, target product sizes, required capacity, moisture, number of fractions, power supply and project location.

Suitability for wet material depends on moisture content, clay content, screen aperture and screen-media design. Materials with high surface moisture or clay may require wet screening, anti-blinding screen media or additional feed preparation.
