Principles of Sieve Shaker
Sieve Shaker Operates based on the principle of size separation through sieving.
Particles are sorted by passing through a stack of sieves with progressively smaller openings, relying on gravity and mechanical motion to achieve separation.
Construction
Sieves: A stack of sieves with different mesh sizes.
Shaking Mechanism: A motor-driven device that imparts a shaking or vibratory motion to the sieves.
Holder: A framework to hold the sieve stack securely.
Base: A sturdy platform that supports the entire apparatus.
Working
The material to be separated is placed in the top sieve.
The shaker imparts a vibratory motion to the sieve stack.
Particles move through the sieves, separating based on size, with smaller particles passing through to the lower sieves.
Each sieve retains particles of a specific size range.
Uses
Used in laboratories and industries for particle size distribution analysis.
Common in quality control processes in pharmaceuticals, food, and construction industries.
Merits
Provides precise and accurate particle size distribution.
Simple to use and maintain.
Versatile, can handle a wide range of materials.
Demerits
Time-consuming for large samples.
Potential for mesh clogging with fine or sticky materials.
Limited to dry materials.
