The upper part of the machine features a quick-release handle, integrating the entire unit into a cohesive whole. The top cover is fully sealed, effectively preventing dust dispersion caused by vibration during the sieving process. A vibration motor is installed at the lower part of the sieve body, ensuring a compact structure for the material. The lower part employs spring damping, allowing the machine to operate smoothly. The base below is adjustable, enabling the adjustment of the sieve surface's tilt angle during sieving to achieve optimal sieving results based on the material's characteristics.
