Vibrating sieves are mechanical tools used to separate solids, liquids, and powders. They are used in various industries and work by vibrating in a circular motion to separate impurities. The mining industry is a major user of this technology, as are manufacturing, archeology, metallurgy, and construction.
A vibrating sieve is a large mechanical tool used to separate solids, liquids and powders. Industries as diverse as mining, chemical companies, and construction companies use these tools to help sort and clean items. Using gravity, motion, and mesh screens, these tools do the work of more people in a fraction of the time.
A vibrating screen separator is about the size of a metal wheelie bin. It is constructed, many times, of a solid metal such as steel and has two open sides so users can visually monitor the progress of the screen. Most vibrating screeners have four or more levels of screens stacked on top of each other. Screens are made from wire mesh and come in a variety of sizes to fit different jobs.
The vibrating screen works by arranging the items to be separated, such as marbles of different sizes, placed on the screen on the top layer. The entire machine vibrates in a gentle circular motion to work the material through the screens and separate any impurities. Then the different sized marbles would slowly make their way down the many layers of screens, usually with the largest openings in the top layer and getting smaller as the marbles made their way down. The result is a collection of marbles sorted by size, and dirt and excess material is removed. The amplitude of the vibrations can be adjusted to be gentle for delicate materials and more vigorous for harder items.
The mining industry is one of the largest users of vibrating screen technology. Mining ore and minerals from the ground produces a lot of impurities, so these organizations load the goods into a screen until the dirt and non-precious rocks are shaken out of materials such as coal, iron, and ore. Screens are also used in manufacturing, especially when metal objects, such as ionized bolts and screws that need to be soaked in a bath, need to be dried. Here, liquid-filled and metal containers can be poured through the screen and vibrated apart to ensure they dry completely. Industries as disparate as archeology, metallurgy, and construction also use vibrating screen technology to get their jobs done.
