Screening for coarse materials involves the use of a vibrating screen to separate larger particles from smaller ones. Typically, the vibrating screen is made up of a metal mesh with different sized openings that allow larger particles to pass through while retaining smaller ones.

The screening process is important for a number of reasons, including the removal of oversized materials that could potentially damage downstream equipment, as well as the removal of unwanted materials that may reduce the quality of the final product.

In addition to vibratory screens, other types of coarse material screening equipment include trommel screens, grizzly screens, and scalping screens. Each of these devices has its own unique set of advantages and disadvantages and can be used in different applications depending on the specific requirements of the process.
