1. The screening principle of linear vibration screen:
The two vibrating motors move synchronously and oppositely, and the material is thrown up by force and moves forward in a straight line.

2. Factors that affect the trajectory of the material on the screen:
1). The installation angle of the motor: the greater the angle, the greater the span of the parabolic trajectory of the material on the screen surface, so the greater the output, the lower the accuracy.
2). The excitation force of the motor: the magnitude of the excitation force directly affects the parabolic height value of the parabolic trajectory of the material on the screen surface. In addition, the excitation force of the two motors must be equal.
3). The height of the sieve machine: two options of positive and negative angles can be designed.

3. the installation of the screen:
1). Single-layer screen: suitable for materials with better screens, lighter materials and small screen meshes.
2). Parent-child net (support net plus screening net): suitable for relatively good sieves, materials with a heavier proportion of materials and materials that require a small number of screen meshes.
3). Single layer with bouncing balls: suitable for materials that are not well sieved and easily blocked and require pinball cleaning and lighter materials.
4). The parent-child net with bouncing balls (supporting mesh + screening mesh +bouncing ball): suitable for materials that are not well sieved and easy to block the net and need to clear the pinball and heavy materials.

4. Sieve frame material:
1). Wooden sieve frame: low manufacturing cost, easy to change the screen, low probability of damage to the screen, and relatively better sealing.
2). Steel sieve frame: When the material has special requirements, the specific gravity of the material is too high and the particles are larger.

5. Materials and meshes suitable for screening:
1). Quartz sand: 10 mesh, 20 mesh, 40 mesh, 80 mesh, 120 mesh.
2). Activated carbon: 6 mesh, 16 mesh, 24 mesh, 48 mesh.
3). Stone powder: 6 mesh, 16 mesh, 24 mesh, 48 mesh.
4). Refractory materials: 10mm, 8mm, 5mm, 1mm, 40 mesh, 120 mesh.
