Abstract

A sieve shaker or a sieving apparatus translates the mechanical action of separating coarser, solid particles into finer grains in sectors such as pharmaceuticals and materials engineering. Segregating particles according to their desired sizes enables a more comprehensive and precise analysis. The process of sifting is conducted by utilizing specific mesh types and sizes. The movement of the filtering process is determined by the vibrations generated by the sieve shaker. The sieve shaker requires calibration to ensure the measurement accuracy of the sieving process. Accurate measurements provide the fundamental basis for ensuring the quality and safety of the product. The ISO 16063 part 21 is a standard for secondary vibration calibration. However, the back-to-back method mentioned in the standard is challenging to apply directly to calibrate the sieve shaker due to the unique shape of its body component. Therefore, in this study, we adopt a point-symmetrical position applied in primary vibration calibration in order to perform vibration measurements produced by the sieve shaker. The standard accelerometer B&K 8035 is used as a reference transducer to measure the amplitude of the sieve shaker. The measurement was conducted for the displacement range of 0.2 up to 3.00 mm p-p with the highest measurement uncertainty of 2%.
