screenings materials in mineral processing

Screening plays a significant role in a lot of industries. It separates the valuable minerals and materials from the waste rock, debris, and other excessive elements that are not needed for further processing. This process mostly occurs in a huge variety of industries like mining, mineral processing, agriculture, pharmaceutical, food, plastics, and recycling.

The percentage of material at each size will determine the capacity of a given machine. Key factors include the percentage passing the chosen sizing point; the more material required to pass through a screen, the larger the required screen area for the duty. The top-size of the material will also have a direct impact on the material's screening.

If there is little fine material the screening capacity falls. This is due to the fact that there are a lot of particles of limit/critical size. The throughput of particles of limit size (0.5 – 1.0 x hole) is very poor. Effect of material weight on screening. Screening capacity depends on material volume. Effect of particle shape on screening
