Multi-Frequency Vibrating Screen-X
-
X Diagonal Exciter Layout, Multi-layer High-throughput Dry Classification: Symmetric X layout of exciters optimizes material throwing angle. 2–4 decks conduct simultaneous classification to output 3–5 finished aggregates in one unit, throughput increased by 15% vs same-size circular screens, suitable for precise dry grading of 3–80mm materials
-
Static Non-vibrating Cabinet, Greatly Reduced Foundation Load: Only inner screen cores vibrate with much lower total vibrating mass, cutting dynamic-static load by 50%. Lower overall height & adjustable deck angle remove foundation reinforcement demand to save civil engineering investment.
-
Independent Frequency & Amplitude Regulation by Sections for Higher Screening Efficiency: Separate adjustable vibration parameters for each section match feeding dispersion and end fine screening. Screening efficiency rises by over 5% compared with standard circular screens under identical material conditions with improved fine grain recovery.
1. Product Overview
Multi-Frequency X Screen is a general multi-layer dry multi-frequency screening machine developed for aggregate, metallurgy, coking and thermal power desulfurization industries. Its exciters are arranged in X diagonal layout, adopting split structure with static fixed cabinet and multi-section independent vibrating screen cores. Each section is equipped with separate frequency conversion exciters to freely switch dual modes: low frequency & large amplitude for material stratification, high frequency & small amplitude for precise classification, breaking the uniform frequency & amplitude limitation of conventional circular vibrating screens. It supports 2–4 deck multi-layer screening for 0–150mm medium & lump dry materials. Full static rigid cabinet sealing with negative pressure dust removal completely eliminates dust leakage and short-life flexible sealing defects of traditional circular screens. Lightweight split modular design delivers low foundation load and low civil cost, serving as economical ideal replacement for large & medium imported circular vibrating screens.
2. Detailed Description
The machine consists of fixed base, static cabinet, multi-section independent vibrating cores, X-arranged exciters and damping springs. The cabinet stays static all the time; only inner segmented cores generate self-synchronous linear vibration with adjustable vibration angle.
The feeding section adopts low frequency & large amplitude to create strong throwing force for fast thick-layer dispersion and material conveying; middle & discharge sections switch to high frequency & small amplitude to boost medium-fine particle penetration, while height difference between sections realizes secondary tumbling & stratification. Equipped with PLC touch screen frequency conversion system, it supports remote independent adjustment of frequency, amplitude and start-stop sequence for each section, with switchable linear/compound elliptical vibration tracks. Rivet-reinforced screen cores plus transverse damping springs restrain lateral swing for stable operation and low resonance amplitude. Dust extraction ports are reserved on cabinet for full negative-pressure enclosed screening without dust leakage.
3. Materials
Dry aggregate, manufactured sand, raw coal, metallurgical sinter ore, coke, limestone, steel slag, desulfurization limestone powder, non-ferrous lump ore, dry tailings, construction crushed stone and other dry lump materials with moisture ≤10%, particle size range 0–150mm.

-
Static frame with segmented independent multi-frequency vibratory core, stationary screen box, multi-section adjustable frequency & amplitude for dry material classification: Stationary outer frame without vibration, independent vibratory cores for each deck with separate frequency & amplitude control. Low-frequency large amplitude breaks thick material bed at feeding end, high-frequency small amplitude boosts fine screening. Material loosening coefficient rises by 1.3 times, 5%-10% higher efficiency than circular screens, ideal for dry grading of aggregate, raw coal and metallurgical sinter feed.
-
Fully enclosed static negative pressure sealing, low dust & noise, compliant with green mine emission standards: Rigid gap-free sealing for all feeding & discharging ports eliminates dust leakage caused by moving frame. Dedicated dust extraction outlet maintains negative pressure inside the screen, double sound insulation cuts noise by 8-10dB. Dust air volume demand reduced by 40% to lower supporting fan power for eco-friendly mines, coking plants and power plant desulfurization lines.
-
Light low vibrating-mass structure, drastically reduced power consumption for lower operation cost: Only screen core and decks vibrate with far lower vibrating mass than integrated circular screens. Over 30% power cut under same throughput, saving over 100,000 kWh annually for 3075 model. Multi-point distributed damping weakens ground impact, no heavy reinforced foundation required to cut civil investment.
-
Multi-layer modular screen core, interchangeable multi-material panels, produce 2-5 finished sizes with single unit: Standard 2/3-layer modular cores with independent discharge chutes to avoid multiple screening machines. Optional manganese woven mesh, perforated steel plate and PU panels for coarse lumps, fine aggregate and dry coal. Adjustable deck angle and vibration direction angle adapt to crushing, coal pre-grading and metallurgical raw material sorting.
