A stacked sieve tool has been made to sort natural sands, which will ultimately be used to produce functional materials such as zircon, zirconia, LFP, and polymer-based composite fillers. This stacked sand sieve was intended to replace conventional sieves that had several disadvantages, including unstable speed, inefficient time in processing large amounts of sand, and relatively higher costs incurred. This stacked sieve exhibited the following characters: 1) composed of two sieves, 2) can be assembled easily to change the size of the sieve, 3) had 3 variations of the sieve slope, and 4) used a gasoline motor to produce a sift speed of 25.2 cm/s and 36.4 cm/s. The sieve slopes were manually adjusted by positioning the sieves according to the available slots on the device. The sizes of the filter on the sieves made were 1, 3, and 5 mm. The effectiveness of the stacked sieve was tested using a 50 kg ordinary natural sand. The test results showed that the sieved product increased if it used a speed of 25.2 cm/s. Furthermore, the maximum sieve yield was obtained if the upper and lower sieves were at the same slopes, which was 38˚, and their sizes were 5 and 1 mm respectively, which was 0.82 kg/s. |
