About Screens

Screens help mining operations and other worksites to break down larger rocks into smaller, more workable materials. Typically working in combination with a crusher, screeners separate rocks, ore, and other aggregate by size, shape, or other characteristics based on the particle. Screens, for example, often have multiple screenboxes with screens of varying sizes, allowing separation anywhere from ultrafine particles to coarse materials. After being separated, the screened aggregate will drop down and be transported to a storage system or another crusher for a second scraping.

Variants & Features

Depending on the operation, screeners might be large machines that work around the clock or portable screeners that move around the jobsite to handle short-term workloads. Mobile units typically feature tracks to more easily get around the rough terrain commonly found at mining sites. Larger screens might offer multiple decks and built-in routing systems to efficiently move various aggregate sizes to different drop-off sites.

The type of screen best for the job also varies, depending on the aggregate you’re working with and final material size. Many screen manufacturers offer inclined, horizontal, banana, and ultrafine options to best suit the processing requirements. Different types of circulation, such as high-frequency vibration, gyratory motion, and circle-throw vibration, can shift materials in ways that optimize the screening process.
