3 Layer 4 Layer Vibrating Screening Equipment High Capacity For Sand Gravel Coal
The 3-layer group contains 3YZ1845, 3YZ2160, 3YZ2460, 3YZ1860 with screen area ranging 24–43.2 m² and throughput between 50 t/h and 700 t/h, paired with motor ratings of 22 KW, 30 KW and 37 KW. The 4-layer lineup consists of 4YZ2160, 4YZ2460, 4YZ2470 whose screen surface expands from 50.4 m² to 67.2 m², delivering throughput spanning 100–750 t/h and motor power of 30 KW, 37 KW, 45 KW accordingly. Extra stacked screen decks can separate incoming crushed stones into three or four standardized particle sizes simultaneously, removing repeated secondary screening procedures from production layouts. Reinforced cross beams are fitted on multi-layer screen frames to bear extra structural weight brought by stacked decks. Separated chute outlets are arranged at different elevations to discharge sorted materials neatly.

Powerful vibration motors produce stable circular excitation to shake the multi-layer screen assembly. Raw aggregate cascades sequentially through stacked screens with descending aperture sizes. Every deck intercepts one specific particle size band, and separated bottom outlets collect corresponding finished fractions. Reinforced transverse stiffeners prevent frame bending caused by the extra dead load of three or four mesh decks. Tuned spring banks at four corners of the base absorb intensified vibration loads of heavier multi-tier screen housings.
- 3-layer layouts produce three aggregate grades and 4-layer layouts yield four grades within one screening cycle, simplifying whole plant layouts greatly
- Rich screen-area selection (24 m² to 67.2 m²) covers low-output quarry branches and mainstream medium-large aggregate factories
- Gradually upgraded motor power from 22 KW up to 45 KW matches rising structural mass and screening workload of higher-layer variants
- Reinforced internal beam reinforcement raises frame rigidity and extends service life of stacked multi-deck screen boxes
- Height-distributed independent outlets avoid finished-product mixing and simplify downstream conveyor layout planning
