The BA200N sieve shaker is a highly versatile laboratory device designed to perform particle size analysis efficiently and accurately. Its operation is based on the combination of vibratory movements that allow for the separation of particles of different sizes by passing them through a series of stacked sieves.
General Procedure
-
Preparation of the Sieves:
- Selection: Choose the appropriate sieves according to the range of particle sizes you wish to analyze. Ensure they are clean and dry, sieve cleaning .
- Stacking: Place the sieves on the sieve shaker in decreasing order of aperture size, with the largest aperture sieve at the top.
-
Preparation of the Sample:
- Homogenization: Ensure the sample is well-mixed to guarantee an adequate representation of the size distribution.
- Quantity: The amount of sample will depend on the capacity of the sieve shaker and the size of the particles.
-
Loading the Sample:
- Placement: Pour the sample evenly onto the top sieve.
-
Closing the Sieve Shaker:
- Fastening: Ensure the lid of the sieve shaker is securely closed to avoid material loss during the process.
-
Programming:
- Time: Set the sieving time according to the characteristics of the sample and the sieves used.
- Amplitude: Adjust the vibration amplitude to optimize particle separation.
-
Starting the Process:
- Activation: Start the sieving process by pressing the corresponding button.
-
Completion and Collection:
- Stopping: Once the programmed time has elapsed, the sieve shaker will stop automatically.
- Collection: Remove the sieves and collect the particle fractions retained on each of them.
Important Considerations
- Calibration: It is essential to calibrate the sieve shaker periodically to guarantee the accuracy of the results.
- Cleaning: Clean the sieve shaker and the sieves after each use to prevent contamination of future samples.
- Safety: Follow laboratory safety regulations and use appropriate personal protective equipment.
Advantages of the BA200N
- Versatility: Allows for both dry and wet analysis.
- Accuracy: Offers highly precise and reproducible results.
