The operating procedure of a sieve shaker is as follows:
1. Switch on the electric power supply to the sieve shaker.
2. Arrange the sieves in ascending order, with the sieve with the largest aperture on the top and the sieve with the smallest aperture on the bottom.
3. Clamp the sieves to the equipment and tighten them with the screw provided on the top.
4. Switch on the sieve shaker equipment.
5. Adjust the vibration power of the sieve shaker so that a vibration of 1-2 mm amplitude is maintained.
6. The sieve shaker machine uses a vertical vibration motor as the vibration source. The motor drives the upper vibrating plate to vibrate, transmitting the vibration through the vibrating plate to the screen frame on the upper part of the vibrating plate.
7. The material particles smaller than the aperture of the screen are sieved to the lower screen frame, while larger particles remain on the upper screen frames. This achieves the separation of different particle sizes and determines the particle size composition of the material.
8. The sieve shaker is used to filter, grade, and screen materials effectively based on their particle size composition.
9. For particles smaller than 50 microns, additional techniques such as ultrasonic agitation or vacuum-assisted sieving may be required to effectively separate these small particles.
10. The purpose of the sieve shaker is to expedite the passing of particles smaller than the openings in the sieves by exposing the sample to all the sieve openings.
11. The selection of the appropriate sieve shaker depends on the size and characteristics of the sample to be separated.
12. A sieve shaker is an instrument used in particle analysis to shake a stack of test sieves in order to sift materials through according to particle sizes.
13. Sieve shakers can replace manual hand sieving and offer advantages such as sample size reduction, material separation, and improved efficiency.
14. Test sieve shakers can utilize a maximum of 10 test sieves in one experiment, while manual hand sieving is more restricted due to the weight of samples and test sieves.
15. Using a sieve shaker reduces or eliminates single-operator differences and improves efficiency by agitating multiple sieves simultaneously and consistently.
16. Selecting a sieve shaker compatible with the sample material's characteristics enhances accuracy, repeatability, and efficiency.
17. There are accessories available to streamline the process of collecting, weighing, and calculating sieve fractions during particle analysis.
