1. Basic specifications

specifications and models:

2YA:

Double-layer screen (three layers if it is 3YA )

Y:circular vibrating screen (the motion trajectory is circular)

A: Improved design

2160: screen width 2100mm × length 6000mm

Screening area: single layer about 12.6 ㎡ (effective screening area about 11.5 ㎡)

Maximum feed particle size: 300mm (≤200mm is recommended to increase the life of the screen) Processing capacity: 150-600 tons/hour (depending on the material type, humidity and screen hole size)

2. Vibration parameters

Vibration motor:

Model: YZO-30-6 (2 units, symmetrically arranged) Power: 2×15kW (380V, 50Hz)

Exciting force:2×100kN (adjustable eccentric block to adjust the amplitude)

Vibration frequency: 800-1000 times/minute

Amplitude:48mm (double amplitude)

Screen surface inclination: 15°-25° (adjustable, usually set to 20°)

3. Screen configuration

Screen layers: 2 layers (upper coarse screen, lower fine screen)

Screen hole

size: Upper layer: 50-100mm (such as separating large pieces of waste rock)

Lower layer: 5-30mm (such as grading aggregate)

Screen material:

High manganese steel woven mesh (wear-resistant, life 6-12 months)

Polyurethane (PU) screen plate (anti-blocking,suitable for wet and sticky materials)

4.Structural design

Screen box material: Q345B steel plate (main beam thickness ≥14mm, side plate ≥10mm)

Support method:

Spring vibration reduction: rubber composite spring or steel spring (reduce foundation load) Foundation dynamic load: ≤50kN (pre-buried anchor bolts are required)

Sealing and dustproof: fully enclosed structure (optional dust removal interface)

5.Applicable materials and industries

Sand and gravel aggregate: crushing and classification of granite and basalt (0-5mm, 5-10mm, 10-20mm, etc.) Mineral processing: pre-screening or tailings dehydration of iron ore and copper ore Coal industry: raw coal classification (≤80mm)

6. Equipment size and weight

Overall dimensions (length × width× height): ≈6500mm×2800mm×3200mm (including motor frame)

Machine weight: about 8-12 tons (depending on material and configuration)

7.Optional configuration

Intelligent control:

Frequency conversion speed regulation(adjust vibration frequency to adapt to different materials)

Blockage alarm system (interlocked shutdown with production line)

Wear-resistant upgrade: Tungsten carbide coating is added to the screen (life is extended by 2 times)

Water spray dust suppression device (for high dust materials)

Key points

1.Selection points:

For high- humidity materials (water content > 8%), it is recommended to choose polyurethane screen plates or increase the inclination angle of the screen surface. Viscous materials (such as clay) need to be equipped with a bouncing ball anti-blocking device.

2. Installation requirements:

The foundation level deviation is ≤2mm/m, and the thickness of the embedded steel plate is ＞30mm. A 500mm buffer space is reserved between the screen machine and the feeding/discharging equipment.

3. Maintenance cycle:

Check the tension and damage of the screen every 300 hours.

Replace the damping spring every 6 months (the rubber needs to be replaced in time)

Typical application process

Sand and gravel production line: Crusher discharge 2YA2160 (upper layer screening removes return material > 30mm, lower layer screening 5-30mm aggregate)  belt conveyor Iron ore concentrator: Ball mill discharge  Vibrating screen (classification + 0.15mm fine particle dehydration)

Magnetic separator If  need a more detailed screening efficiency curve or processing capacity correction factor

for different materials, please provide specific material characteristics (such as bulk density, mud content, particle shape, etc.).
