The test sieve shaker utilizes a new vibration motor as its excitation source, converting the motor's rotational motion into horizontal, vertical, and inclined three-dimensional motion. This vibration is transmitted to the standard analysis sieve and the material on the sieve surface, enabling precise particle size classification.The working principle of the test sieve is based on the principle of vibration screening. The test sieve is usually composed of a screen frame, a screen, a vibration mechanism and a supporting structure. When the test sieve is started, the vibration force generated by the vibration mechanism is transmitted to the screen frame, causing the screen frame and the screen to vibrate. After the particles are put into the screen frame, they are affected by the vibration force and jump on the screen. Small particles fall into the container below through the screen holes, while large particles remain on the surface of the screen. Through screens of different specifications, particles of different particle sizes can be separated and classified. Particles are separated during vibration, and the screening effect is affected by parameters such as amplitude and frequency. After screening, particle size analysis can be performed based on particle distribution to provide data support for production process optimization and product quality control.
