Inclined Vibrating Screen

Inclined vibrating screens operate at a typical 20° angle with circular motion generated by an eccentric shaft drive, creating an optimal balance between material travel speed and screening efficiency. Unlike horizontal screens, the inclined design uses gravity to assist material flow, resulting in higher throughput capacity and better stratification. Compared to multi-slope (banana) screens, inclined screens feature simpler construction and lower installation height, making them ideal for applications with space constraints or where simplified maintenance is preferred. The circular motion pattern provides excellent screening performance for most mining and aggregate materials with particle sizes from 5-100mm.

The ZXYA Series excels in aggregate screening applications through several key advantages: The precise circular motion pattern provides thorough material stratification and separation for accurate sizing of construction aggregates like crushed stone, gravel, and sand. The multi-deck configuration allows producers to simultaneously create multiple product sizes in a single pass, increasing operational efficiency. The robust construction with reinforced side plates and premium bearings handles the abrasive nature of aggregate materials while maintaining consistent performance even under continuous heavy loading. Finally, the straightforward design offers simplified maintenance and lower operating costs compared to more complex screening systems, making it particularly suitable for small to medium aggregate producers.

The ZXYA Series supports multiple screen media options including woven wire mesh, punched plate, polyurethane panels, and rubber panels. Woven wire mesh offers high open area percentage (35-45%) for maximum throughput but with shorter wear life in abrasive applications. Punched plate provides excellent durability with moderate open area (25-35%), balancing capacity and service life. Polyurethane and rubber panels deliver superior wear resistance for highly abrasive materials, though with lower open area (20-30%). Our application engineers can recommend the optimal media type based on your specific material characteristics, target particle size, and moisture content to balance screening efficiency, capacity, and maintenance intervals in your operation.

The eccentric shaft drive system in the ZXYA Series creates consistent circular motion through mechanical precision rather than electrical adjustments, delivering several performance benefits: The uniform circular trajectory ensures even material distribution across the entire screen surface, eliminating dead zones and maximizing effective screening area. The mechanically generated motion maintains stable amplitude regardless of load variations, ensuring consistent screening performance even with fluctuating feed rates. The robust design handles higher G-forces (typically 4-5G) than comparable electrical systems, effectively preventing screen blinding and improving separation efficiency with challenging materials. Additionally, the mechanical simplicity of the system results in lower maintenance requirements and enhanced reliability in dusty and harsh operating environments typical in mining applications.

To maintain optimal ZXYA Series performance, operators should implement several key maintenance practices: Regular inspection of bearing lubrication systems (weekly checks and monthly greasing) to prevent premature bearing failure. Screen media tension checks every 100 operating hours to ensure proper tensioning and prevent material bypassing. Eccentric weight balancing confirmation quarterly or after any drive component replacement to maintain proper motion patterns. Rubber spring mount inspection every 500 hours for signs of deterioration or damage. Regular cleaning of dust seals and motor cooling fins to prevent overheating. Following these maintenance protocols typically results in 20-30% longer component life and significantly reduces unplanned downtime. Most operators report maintenance requirements of just 4-6 hours per month for routine servicing.

The ZXYA Series addresses high-moisture material challenges through several design elements: The circular motion generated by the eccentric shaft creates a constant agitation that helps prevent material adhesion to screen surfaces. The optimized 20° inclined angle improves material flow velocity, reducing residence time where blinding might occur. The higher G-force capabilities (adjustable up to 5G depending on model) provide aggressive material movement that helps dislodge sticky particles. For particularly challenging materials, the system can be configured with specialized anti-blinding screen media options including self-cleaning wire mesh, ball deck cleaning systems, or spray bars for material conditioning. These features collectively enable the YA Series to maintain screening efficiency with materials containing up to 15-20% moisture content, though performance will gradually decline as moisture levels increase beyond this range.

Key installation considerations for the ZXYA Series include: Robust foundation design to support dynamic loads (typically requiring 1.5-2 times the static weight capacity), with proper vibration isolation to prevent transmission to surrounding structures. Adequate feed distribution system to ensure even material presentation across the full screen width for maximum efficiency. Sufficient headroom clearance (minimum 1.5m above the screen) for maintenance access and screen media replacement. Proper chute design below each deck to efficiently collect and direct classified materials without buildup or blockage. Dust containment systems where required by operational or environmental considerations. Our engineering team provides comprehensive installation guidance including 3D models for integration planning, foundation load calculations, and connection details to ensure optimal performance in your specific processing circuit.

Operations upgrading to the ZXYA Series typically experience capacity improvements of 15-25% compared to older vibrating screen technologies, with several contributing factors: The optimized circular motion pattern improves material stratification, allowing more efficient separation and higher throughput without sacrificing product quality. The enhanced vibration intensity (adjustable to application requirements) helps overcome blinding issues that limit capacity in conventional screens. The robust drive system maintains consistent performance under varying load conditions, preventing the efficiency losses common in older designs during feed surges. The improved screen media tensioning system minimizes premature wear and blinding, maintaining optimal open area throughout operating cycles. These efficiency gains translate to higher throughput with the same footprint, making the YA Series an ideal upgrade path for operations seeking increased production without major infrastructure changes.

The ZXYA Series delivers optimal performance in the 5-100mm size classification range, with efficiency characteristics that vary by particle size: For coarse material separation (40-100mm), efficiency rates typically exceed 95% with throughput capacities at the higher end of the specification range. For medium-sized material (10-40mm), separation efficiencies of 90-95% are standard with balanced capacity and precision. For finer screening (5-10mm), efficiency remains strong at 85-90% though throughput capacity is reduced compared to coarser applications. While the YA Series can be configured for separations below 5mm, alternative technologies may offer better performance for ultra-fine applications. The multi-deck configuration enables simultaneous classification of various size fractions, making the YA Series particularly effective for producing multiple product grades in a single processing stage.
