YK Vibrating Screen

Introduction
METRO YK Vibrating Screen is a circular motion screening machine widely used in mining, aggregate production, and construction. It consists of a screen box with multiple decks (typically 2–4 layers), a vibrating exciter (eccentric shaft or block), and a heavy-duty frame. The exciter generates a circular vibration trajectory, which causes material to stratify and move across the screen surface, allowing fine particles to pass through the mesh openings while oversize material is conveyed forward and discharged.

Applications

• Mining-Screening iron ore, copper ore, gold ore, coal, limestone, and other minerals
• Aggregate production-Classifying crushed stone, gravel, sand, and recycled aggregates into graded fractions
• Construction & Road building-Producing aggregates for concrete, asphalt, and road base materials
• Quarrying-Screening materials after primary/secondary crushing (jaw, cone, or impact crushers)
• Metallurgy-Separating ores and sintered products
• Chemical & Industrial-Screening gypsum, phosphate, barite, and other bulk materials
• Recycling-Separating construction and demolition waste into reusable fractions

Features & Advantages

• Circular vibration trajectory-Provides efficient stratification and prevents plugging-ideal for wet and sticky materials.
• Multi-deck design (2–4 layers):Produces 3–5 different product sizes in one machine-saves space and cost.
• Adjustable amplitude & frequency-Optimizes screening performance for different materials and moisture contents.
• Heavy-duty screen mesh-Available in woven wire, punched plate, or polyurethane-long service life and easy replacement.
• Easy mesh replacement-Quick-release tensioning system reduces downtime to minutes.
• Simple structure-Few moving parts; reliable operation with low maintenance requirements.
• Grease-lubricated bearings-Sealed for life-no oil circulation system needed; reduces maintenance complexity.
• High screening efficiency-Up to 85-95% for properly sized materials-ensures accurate separation.
• Wide model range-From small lab units to large industrial screens (1–10+ decks, 0.5–5+ m width).
• Durable frame-Heavy-duty welded steel construction with bolted or riveted joints.

Key Benefits

• Accurate classification-Produces consistent, high-quality aggregates meeting construction standards.
• High capacity-Handles large volumes in a compact footprint.
• Versatile-Works with dry, wet, and sticky materials.
• Low operating cost-Energy-efficient motors and long-lasting screen media.
• Protects downstream equipment-Removes fines and oversize before they enter crushers or conveyors.

Main Components

• Screen box-Main body holding all decks and mesh; made of welded steel.
• Vibrating exciter-Eccentric shaft or unbalanced blocks that generate circular motion.
• Screen deck (layers)-Horizontal or slightly inclined layers of screen mesh (2–4 typically).
• Screen mesh-Woven wire, punched plate, or polyurethane panels with specified openings.
• Tensioning system-Springs or bolts that secure mesh and allow quick replacement.
• Vibration dampers-Rubber or coil springs that isolate vibration from the supporting structure.
• Motor-Electric motor (typically 5.5–45 kW) driving the exciter via V-belts.
• Feed box-Distributes material evenly across the top deck.
• Discharge chutes-Directs each product fraction to separate conveyors or stockpiles.
