Analytic Sieve
What is Analytic Sieve?
Analytic Sieve, named for its precise particle size analysis capability, is a laboratory screening device integrating multi-layer sieve frames and a controllable vibration system. Featuring a modular design, it uses electromagnetic drives or speed-controlled motors as power sources, paired with internationally certified sieves (e.g., ISO 3310), enabling high-precision grading from coarse particles to nano-level powders. Typical models like the AS-200 series support 1-8 layers of sieve frames, with screening areas ranging from 0.03 to 0.15 m², suitable for 5-200g samples to meet laboratory-grade particle size analysis needs in pharmaceuticals, materials, food, and other fields.
How does the Grading System of Analytic Sieve work?
Coarse grading (4-60 mesh): Suitable for primary screening of ores, grain impurity removal, etc.
Medium grading (60-325 mesh): Commonly used for particle size detection of building materials (e.g., cement, quartz sand).
Fine grading (325-2000 mesh): Specifically designed for nanomaterials, catalysts, etc.
What is the Working Principle of Analytic Sieve?
The device achieves material grading through high-frequency vibration of sieve meshes driven by a vibration source:Power transmission: Electromagnetic vibrators or speed-controlled motors drive eccentric blocks to rotate, generating 3D vibrations (vertical ejection + horizontal displacement) with a frequency of 50-300Hz and amplitude of 0.1-2mm.
Material screening: After samples are added to the top sieve frame, particles smaller than the sieve aperture pass through to the lower layer under the combined action of vibration and gravity, while larger particles remain until discharged from the outlet.
Data generation: After screening, the mass of residues on each layer is weighed, and particle size distribution curves (e.g., D10, D50, D90) are automatically generated based on sieve aperture parameters, with errors controlled within ±3%.
