The most popular of several similar devices, the Shaking Table was developed in the 1890s. It has been in use since and is a common device for concentrating particles in the intermediate range, such as 10-200 mesh (1.65 mm-74 pm) particles for ore and 3-100 mesh (6.7 mm-150 pm) for coal. It is an oblong, shaken deck, typically 1.8- to 4 ...Web

Shaking tables, also known as shaking concentrators or gravity separation tables, are equipment for mineral processing and ore separation based on density, particle size, and shape differences.
