Linear screens screen granular materials through horizontal vibrating screens. The main advantages are high screening efficiency, easy maintenance and cleaning, and are suitable for handling large amounts of granular materials. However, the screening accuracy of linear screens is relatively low, making it difficult to finely classify particles.

The rotary vibrating screen sieves granular materials through the rotational vibration of the screen cylinder. Its screening accuracy is relatively high and it is suitable for fine classification of particles and removal of impurities. In addition, due to the use of rotary vibration, the rotary vibrating screen has a better screening effect on viscous materials.

Therefore, the choice to use a linear screen or a rotary vibrating screen depends on the specific screening requirements and the characteristics of the granular material.
