during normal operation of a vibrating screen. The geometry was modeled after a spring taking its dimensions directly from the fractured specimen. A FEM analysis was then performed using ANSYS Mechanical. In order to consider the weight of the components and the load of the vibrating screen, a static scenario was first evaluated to obtain the mean
1. The vibrating screen has larger force of vibration and friction which causes the wear of the machine parts. The higher friction of the conventional vibrating screen leads to higher power requirement for instance in industries the motor power requirement is around 7.5 kW to 15 kW. 2.
VIBRATING SCREEN – CAPACITY CALCULATIONS Throughput per square foot of screen area is the name of the screen game, and no design engineer wants to be considered short in the area of capacity and efficiency.

Vibratory Screens come in a variety of sizes. They can range from 4' to 12' wide and 6' to 32' long. The width of the screen determines the carrying capacity of the screen deck, while the length of the screen determines the overall efficiency of the screen. Typically, the length of the screen is 2.5 to 3 times the size of the width.
