A sieve shaker is a machine designed to separate particles based on their size by agitating a sample through a series of mesh filters.
This process is crucial for quality assurance and control in various industries.
The operation of sieve shakers can be mechanical or electromagnetic, each employing different mechanisms to achieve efficient particle separation.
4 Key Mechanisms of Sieve Shakers: Mechanical vs. Electromagnetic
Mechanical Sieve Shaker
Mechanical sieve shakers use a motorized system to create a series of motions that agitate the sieve stack.
These motions can be either a single oscillating motion or a combination of oscillating and tapping motions.
For example, the W.S. Tyler RO-TAP RX-812 uses a single oscillating motion, while the RO-TAP RX-29 employs both oscillating and tapping motions.
This mechanical agitation helps distribute the sample evenly across the sieving surface, ensuring that all particles have an equal chance of interacting with the sieve openings.
Electromagnetic Sieve Shaker
In contrast, electromagnetic sieve shakers utilize an electro-magnetic drive to move a spring-mass system, which transfers the resulting oscillation to the sieve stack.
This method allows for digital setting and continuous monitoring of parameters such as amplitude and sieving time by an integrated control unit.
This precision ensures reproducible and accurate sieving results, making it a common choice in laboratory settings.
The throw-action in these shakers involves a vertical throwing motion overlaid with a slight circular motion, which helps in distributing the sample over the entire sieving surface.
This motion increases the likelihood of particles passing through the sieve openings, as they may present different orientations to the mesh upon each return to the sieve surface.
Working Principle
The fundamental principle of a sieve shaker is to expose the sample to all openings in the sieve in a way that accelerates the passage of smaller particles through the mesh.
The machine uses a vibration motor, such as the YZU vertical vibration motor, to drive the upper vibrating plate, which in turn transmits the vibration to the screen frame.
This vibration causes particles smaller than the aperture of the screen to pass through to the lower screen frame, leaving only materials of the same particle size in each screen frame.
This process effectively separates different particle sizes and determines the particle size composition of the material, facilitating efficient filtering, grading, and screening.
Selection Criteria
The selection of the appropriate sieve shaker depends on the size and characteristics of the sample to be separated, ensuring optimal performance and accurate results in particle size analysis.
