Vibrating screen is widely used in the coal screening process because of its simple structure and high screening performance. 87% of the global energy consumption comes from fossil energy (Michal, Dominik, & Katarzyna, 2017) and vibrating screen accounts for 25%–33% of the total equipment number in a modern coal preparation plant (Peng et al., 2019).

The dependence of the screening efficiency on the screen's length is shown in Fig. 4. The adopted parameters were the following: the vibrations amplitude is Y = 4 mm, the screen's inclination angle is α = 25° and the aperture size a = 1.5 d. Fig. 4: Influence of the screen's length on the screening efficiency.

The screening efficiency of linear vibrating screen. The result shows that the linear vibrating screen has the maximum screening efficiency of 65.92% for first 10 minutes of screening and reduced up to 59.34% for 60 minutes of screening. The reduction in screening efficiency with respect to screening time is due to the screen blinding.

Importance of Vibrating Screen Capacity. Knowing the vibrating screen capacity helps in designing and optimizing the screen layout for a processing plant. It ensures that the screen can handle the expected load, improving efficiency and preventing operational issues such as overloading or underutilization. Frequently Asked Questions
