Stainless Steel Powder Vibrating Screen

This stainless steel powder vibrating screen is an anti-clogging, high-precision industrial sieve for fine powder separation. It features SS304/316L construction, adjustable mesh from 20 to 500 mesh, and 1-5 layer configurations for multi-grade classification.

Static buildup and particle agglomeration cause screen blinding, reduced throughput, and inconsistent quality — especially with ultra-fine metal powders, pharmaceuticals, and food-grade materials. This stainless steel powder vibrating screen addresses these with anti-static grounding, optional ultrasonic systems (20-40 kHz), and explosion-proof configurations.

Whether processing 3D printing metal powders, pharmaceutical excipients, or food ingredients, this stainless steel powder vibrating screen delivers consistent results with minimal downtime. Its stainless steel construction resists corrosion, maintains purity, and meets GMP/FDA standards.

Key Features & Benefits

Anti-Static & Anti-Clogging – Anti-static grounding devices dissipate charge before accumulation. Optional ultrasonic system (20-40 kHz) breaks surface tension, preventing adhesion for powders below 50μm.

Hygienic Construction – SS304/316L contact parts with mirror-polished interior (Ra ≤ 0.4μm), no dead corners. Meets GMP/FDA standards.

Explosion-Proof Option – ATEX-certified motors and controls for combustible metal powders (titanium, aluminum, magnesium) in Zone 21/22 environments.

High-Precision Screening – Separates down to 20μm (635 mesh) with up to 95% efficiency for 20-200μm powders.

Multi-Layer Design – 1-5 decks enable up to 6 grade separations in a single pass.

Quick Mesh Change – Quick-release frame system allows mesh changes in 3-5 minutes.

Optional Ultrasonic System – Dedicated add-on for ultra-fine powders. Increases throughput by up to 300% and extends mesh life.

Technical Specifications

Selection Guide: DH-400/600 for under 500 kg/h; DH-800 for 500-2,000 kg/h; DH-1000/1200 for over 2,000 kg/h. Custom configurations available.

Working Principle

The stainless steel powder vibrating screen uses a vertical vibratory motor to generate excitation force, creating three-dimensional elliptical motion. Material moves from the center to the periphery in a spiral path. Fine particles pass through the mesh; oversize particles discharge at the outlet. Multi-layer configurations enable simultaneous multi-grade separation.

The optional ultrasonic system (20-40 kHz) transmits high-frequency vibrations to the screen mesh, breaking surface tension and preventing fine powder adhesion — critical for materials below 50μm.

Applications

Metal Powder Metallurgy – Purity and particle size distribution directly affect final component density and strength. Explosion-proof option is essential for reactive powders like titanium and aluminum.

3D Printing – Classifies virgin metal powders pre-print and reclaims unused powders post-print. Anti-static features prevent agglomeration; ultrasonic system ensures consistent screening down to 20μm.

Food Processing – Removes oversize particles and foreign matter while maintaining purity. Sanitary design with mirror-polished surfaces meets HACCP and FSSC 22000 standards.

Pharmaceutical – Crevice-free construction prevents product retention and cross-contamination. Ideal for API classification, excipient screening, and herbal powder processing.

Chemical & New Materials – Handles abrasive, corrosive, or static-prone materials including LFP and NCM cathode powders. Explosion-proof configuration available.

Powder Coatings – Removes oversize particles and agglomerates that cause surface defects. Anti-clogging features ensure uninterrupted production.

FAQ

SS304 vs SS316L?

SS304 is standard food-grade stainless steel. SS316L contains molybdenum for enhanced chloride corrosion resistance — preferred for pharmaceutical and high-salinity applications.

How does ultrasonic prevent blinding?

High-frequency vibrations (20-40 kHz) transmitted to the mesh break surface tension between powder particles and mesh wires, preventing adhesion and keeping openings clear.

Can it handle high temperatures?

Standard units handle up to 80°C. Custom heat-resistant configurations available for higher temperatures.

How long to change mesh?

3-5 minutes with the quick-release frame system.

Minimum order quantity?

Single machine orders accepted. Laboratory-scale models also available.
