An electrical sieve shaker is a mechanical device used in laboratories and industrial settings to perform particle size analysis of granular materials through sieving. This equipment automates and standardizes the sieving process, ensuring efficient and consistent results compared to manual sieving methods.
 
Key Components and Features:
1. Base Unit:
   - The main body of the sieve shaker houses the motor, controls, and mechanisms for shaking the sieves.
   - Typically made from sturdy materials like metal or robust plastics to withstand frequent use and vibration.
2. Motor and Shaking Mechanism:
   - Powered by an electric motor that drives the shaking action.
   - The shaking motion is controlled and can be adjusted for intensity and duration depending on the material being sieved and the required particle size analysis.
3. Platform or Tray:
   - A platform or tray on which the sieves are securely placed during operation.
   - Designed to accommodate multiple sieves stacked one above the other, usually up to six or eight sieves depending on the model.
4. Clamping System:
   - Mechanism to secure the sieves firmly in place on the platform during operation.
   - Ensures that the sieves remain stable and do not move or displace during shaking.
5. Controls and Settings:
   - User-friendly control panel with buttons or knobs to start, stop, and adjust the shaking process.
   - Some models feature digital displays for setting parameters such as shaking time and intensity.
6. Shaking Patterns:
   - Offers various shaking patterns such as orbital, circular, or tapping motions.
   - These patterns are designed to effectively move and agitate the particles through the sieve mesh for accurate particle size separation.
7. Safety Features:
   - Built-in safety features such as automatic shut-off to prevent overheating or damage in case of prolonged use.
   - May include protective covers or guards to shield users from moving parts.
8. Compatibility with Sieves:
   - Designed to work with standard sieves made from materials like stainless steel or brass.
   - Accommodates sieves of different diameters (typically 200 mm or 300 mm) and mesh sizes as per the testing requirements.
