Stainless Steel Analysis Sieve

​What is Stainless Steel Analysis Sieve?​

 The  Stainless Steel Analysis Sieve is a precision screening equipment designed for particle size analysis and classification of powdery, granular, and fibrous materials. It leverages high-grade stainless steel (such as 304 or 316L) for its corrosion resistance, durability, and hygienic properties, making it ideal for applications requiring high purity and resistance to chemical erosion. Unlike traditional sieves, it integrates mechanical vibration systems with modular stainless steel structures to achieve accurate particle size separation, widely used in laboratories, quality control, and industrial production for materials ranging from 10μm to 5mm.

How to choose the mesh type of stainless steel analysis screen?

The selection of mesh types (woven, perforated, round hole, square hole) depends on material properties and screening goals:

Woven Mesh: Made of interlaced stainless steel wires, it offers precise aperture control (10μm-1mm) for fine particles. Ideal for powdery materials like pharmaceutical APIs (≤50μm) and food additives, ensuring high accuracy in particle size analysis.

Perforated Mesh: Created by punching holes in stainless steel sheets, it suits coarse materials (>1mm) such as ores and granules. Its robust structure withstands abrasion, making it suitable for metallurgical or mineral analysis.

Round Holes: Smooth-edged round apertures minimize material adhesion, perfect for sticky substances (e.g., wet powders) or spherical particles. They reduce clogging and ensure consistent flow in chemical or cosmetic ingredient screening.

Square Holes: With straight edges and larger open areas, they enhance throughput for angular particles (e.g., fibrous materials or crushed minerals). Ideal for high-volume analysis in construction material testing.

What is the Working Principle of Stainless Steel Analysis Sieve?
 

​

The sieve integrates mechanical vibration with stainless steel structural advantages to achieve precise particle separation​.
 
Vibration-Driven Screening:The vibration motor induces horizontal and vertical oscillations, causing materials to move in a spiral pattern across the sieve surface. Smaller particles pass through the mesh, while larger ones are retained and discharged from the upper layers.​
 
Particle Size Classification Mechanism:Materials enter the top sieve and are distributed evenly by the vibration. Particles smaller than the mesh aperture fall through to the next layer, while oversize particles are transported to the outlet. This process repeats until final grading.​
 
Anti-Blinding & Self-Cleaning:For sticky materials, optional ultrasonic waves or rubber balls attached to the undersurface of the sieve prevent mesh clogging. The stainless steel’s smooth surface further reduces particle adhesion.​
 
Intelligent Control (Advanced Models):PLC-based controllers enable real-time monitoring of vibration parameters (frequency, amplitude) and screening time, generating particle size distribution reports with an error margin ≤1%.

What is the Structure of Stainless Steel Analysis Sieve?​

The structure combines stainless steel modularity ， vibration technology for reliable and precise screening.​

​Multi-Layer Stainless Steel Sieve Frames:1-10 stackable frames with graded mesh sizes (20-2000 mesh/850μm-7μm) support multi-level classification. Coarse layers (20-200 mesh) use 304 stainless steel for robust materials like ores, while fine layers (200-2000 mesh) employ 316L stainless steel for corrosive or food-grade applications. Precision-welded rims prevent leakage, and interchangeable mesh plates allow for quick specification changes.​
 
Vibration Drive System:An eccentric vibration motor generates 3D circular vibrations (100-300Hz frequency, 0.5-2mm amplitude) to ensure uniform screening and efficient material flow. For high-adhesion materials, optional ultrasonic transducers (30-40kHz) can be integrated to prevent mesh blinding.​
 
Hygienic & Corrosion-Resistant Design：The mirror-polished stainless steel surfaces (Ra≤0.8μm) meet GMP standards by minimizing particle adhesion and simplifying cleaning. Sealed rubber gaskets between frames prevent dust emissions, making the sieve suitable for handling hazardous or fine powders.​
 
Modular & Adjustable Features:Quick-clamp mechanisms enable rapid frame assembly and disassembly within 5 minutes. Adjustable vibration angles and speeds optimize screening efficiency for varying material viscosities, with the capacity to process 100g-5kg samples per batch.​
