Bearing and Shaft in a Screen

There are the simplest of vibrating screens where they have a single shaft with an eccentric mass that rotates to induce vibration. The screen frame is supported on springs to allow it to move freely in a circular motion. The screens have to be inclined as these machines rely on gravity to convey oversized material along the screen.

The eccentric shaft is mounted on the counter-weight, i.e. the foundation. Variations: Small vibrating machines with slider-crank mechanisms are designed as guided one-mass systems. Larger vibrating machines have larger dynamic forces and are thus constructed as two-mass systems. These are predominantly designed as so-called resonance systems.

Mechanical screening - Wikipedia

Mechanical screening, often just called screening, is the practice of taking granulated ore material and separating it into multiple grades by particle size.. This practice occurs in a variety of industries such as mining and mineral processing, agriculture, pharmaceutical, food, plastics, and recycling.. A method of separating solid particles according to size alone is called screening.
