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.
