Multi-Frequency Vibrating Screen-XC
-
Ultra-high Vibration Intensity Relaxation Self-cleaning, Zero Blockage for Sticky Wet Materials: Vibration acceleration is 7 times higher than ordinary screens. High-frequency relaxation deformation of polyurethane panels avoids mesh clogging during long-term continuous operation of 10%-15% moisture sticky lump ore and weathered aggregate, drastically cutting downtime for manual cleaning.
-
Separate Frequency & Amplitude Regulation by Sections, Dual Effect of Stratification & Penetration: Vibration parameters of each section are independently adjustable: feeding section disperses & stratifies, rear sections realize fine screening. Screening efficiency increases by over 12% compared with standard linear screens under identical working conditions, greatly lifting fine powder recovery rate.
-
Static Non-vibrating Cabinet, Greatly Reduced Foundation Load: Only screen decks vibrate, total vibrating mass is much lower than traditional screens with dynamic-static load cut by over 50%. The machine weighs 30% lighter with equal throughput, no foundation reinforcement required and civil construction cost reduced by half.
1. Product Overview
Multi-Frequency XC Screen is a segmented independent relaxation composite screening machine customized for high-moisture & high-viscosity lump ore and aggregate soil removal working conditions. It adopts split structure with multi-layer & multi-section independent relaxation screen decks. The whole screen frame stays static without vibration, and each section is equipped with separate frequency-conversion excitation units to independently set dual modes: low frequency & large amplitude for material stratification, high frequency & small amplitude for fine particle penetration. Its vibration inertial force reaches 22.85 times of gravity, far exceeding conventional screening machines, thoroughly solving blocking, caking and stratification difficulties of sticky wet materials. Equipped with high-elastic polyurethane relaxation panels that realize powerful self-cleaning via continuous reciprocating deformation; fully enclosed static sealed cabinet with optional thermal insulation rock wool to adapt to high & low temperature materials. Featuring lightweight split modular design with ultra-low foundation load and low civil engineering cost, it is heavy-duty high-efficiency screening equipment specially for iron & steel lump ore, wet aggregate, sticky raw coal and metallurgical sinter materials.
2. Detailed Description
The machine consists of multi-layer and multi-section independent relaxation screening units. The base cabinet remains completely static, only polyurethane panels perform high-intensity reciprocating relaxation vibration. The feeding section adopts low frequency & large amplitude to generate strong throwing force for rapid dispersion of bonded ore lumps and thick layer stratification; middle and discharge sections switch to high frequency & small amplitude to boost fines penetration. Continuous stretch-shrink deformation of screen panels peels off adhered silt constantly to eliminate mesh clogging. Height difference between sections realizes secondary material spreading and stratification for fast separation of lumps and fines. The frequency conversion system freely switches linear / compound elliptical vibration tracks, suitable for lump ore and aggregate with moisture content ≤20% and varying viscosity. Full cabinet negative-pressure sealing ensures zero dust leakage during screening.
3. Materials
10%-20% moisture sticky iron lump ore, sinter ore, high-silt aggregate, weathered ore, raw coal, wet coal slime, coke, steel slag, limestone, clay, dense medium coarse materials; lump & granular muddy raw materials with particle size ≥1.5mm.
