Both pieces of mining equipment are a vital part of recovering minerals, but function in different roles. Scrubbers are designed to break up clay, alluvial gravels, and sand by mixing them with water in a tumblerlike setup. This allows the minerals to be freed from materials with a high clay content. Trommels are designed for finer separation.
