Screening Equipment
Vibrating Screen for Mining and Aggregate Screening
Vanore Mining supplies YA vibrating screen equipment for size classification in quarry, aggregate and mineral processing plants. Circular vibration and inclined screen decks separate prepared feed into retained and passing fractions, with multi-deck models for several product sizes in one machine.
YA Circular Vibrating Screens for Size Classification
A vibrating screen separates particles by size as feed travels across an apertured surface. Particles that pass through a deck enter its undersize stream; retained material continues to the discharge. This sizing stage prepares distinct material fractions for stockpiling or further treatment.
Vanore YA models combine a vibrating screen box, deck supports, excitation system and spring supports. In a fixed crushing circuit, the machine can produce graded streams or send oversize back for further crushing. Deck dimensions, aperture arrangement and feed conditions define its role within the plant.

Screen Deck Arrangements
Two-deck models
Two screening surfaces provide successive size separations within the screen box. Discharge chutes keep the retained fractions and final passing stream separate.
Three-deck models
An additional deck provides another separation stage in the same machine. Deck area, aperture arrangement and feed conditions determine the capacity at each separation.
Apertures and media
Opening size, open area and media construction affect particle passage and wear. The aperture arrangement must suit the required product fractions and the physical feed.
Fixed or mobile installation
The YA screen is a screening machine within a fixed plant arrangement. A mobile screening plant adds its own supporting chassis, feed and conveying layout.
Screen Box, Excitation and Material Distribution
Circular-motion excitation
The excitation system produces motion that moves and stratifies material on the inclined decks, bringing smaller particles toward the screening surface.
Supported screening decks
Deck supports carry the screening media and material load. Media fastening and support condition are part of maintaining the intended screening surface.
Spring-supported assembly
The spring-supported screen box operates separately from the stationary supporting structure. Support layout and clearance must accommodate the designed movement.
Separate product outlets
Each deck has its own retained discharge route. Chute and conveyor arrangements keep product fractions separate or return the designated oversize stream to a crusher.
Vibrating Screen Applications
Quarry aggregate grading
The screen divides crushed stone into fractions for stockpiling or further processing. Feed from primary crushing and secondary crushing must be distributed across the usable deck width. Screening area, opening size and feed grading guide the screen selection so its duty fits the crusher discharge and required products.
Closed-circuit crushing
In a closed circuit, the designated oversize stream returns to the crusher while correctly sized fractions leave the loop. The returning load forms part of the screen feed as well as the fresh material. This arrangement links crusher discharge characteristics with screening duty and the capacity of the connecting conveyors.
Mineral and sand preparation
Size classification can precede mineral treatment or separate fractions within a manufactured-sand circuit. Where washing is part of the line, water handling and the screening configuration need coordinated connections. Fine-screening and dewatering duties require equipment designed for those separations.
Stone, Sand and Prepared Mineral Feed
Suitable duties include prepared crushed rock, aggregates, sand and mineral feed within the selected model limits. Moisture, clay, near-aperture particles and particle shape influence passage through the media. Screen openings can become obstructed by lodged particles or by a buildup of moist fines; media arrangement and feed conditions therefore matter alongside the nominal opening size.

Opening range describes the apertures through which particles pass. Double amplitude describes the full peak-to-peak movement. Capacity varies with aperture arrangement, feed grading, material condition and the required separation; the duty at each deck is evaluated for its particular separation.
Vibrating Screen Assembly
The screen box carries the decks, media and excitation components. Springs connect the moving assembly to its supports, while the drive supplies the excitation system. The feedbox and discharge chutes connect this moving machine to stationary plant equipment without blocking its designed movement.
Screening Within the Crushing Circuit
| Route | Equipment connection | Plant function |
|---|---|---|
| Prepared feed | Feeder, conveyor and feedbox | Distribute incoming material over the screening width |
| Retained fractions | Deck discharge chutes and conveyors | Keep graded material streams separate |
| Return oversize | Return conveyor and secondary or tertiary crusher | Reduce material that exceeds the selected product size |
| Passing fraction | Product conveyor or washing section | Transfer the fraction passing through the lowest deck |
Controlled feeding helps define the incoming stream. Sand washing equipment can follow suitable sizing stages where cleaning is required. The screen, return circuit and product conveyors are coordinated as one material-flow arrangement.
Vibrating Screen FAQ
What does a YA vibrating screen separate?
A YA screen sorts prepared material by particle size through apertured decks. The resulting streams move to stockpiles, further crushing or mineral treatment.
What is the difference between opening size and deck size?
Opening size describes the holes through which particles may pass. Deck size describes the width and length of the screening surface. These are separate specifications with different roles.
What does an additional screen deck provide?
An additional deck provides another size separation and product route. Capacity at each cut depends on usable area, apertures, feed grading, moisture and material distribution.
What does double amplitude mean in the table?
Double amplitude is the full peak-to-peak screen movement. The operating setting follows the requirements of the selected screen assembly.
