What is the Shaking Table?
Shaking tables are rectangular-shaped tables with ribbed decks with a water film flowing on them. Water flowing along the long axis of the table slurries the fed sample. Low-density particles are transported in the fast-moving film, causing fine, high-density particles to fall into the beds behind rifles. With the rapid backward movement of the ...

Investigation of the effects of particle size on the performance of
The separation efficiency initially increased with increasing particle size, peaked, and eventually decreased with increasing particle size. The maximum separation efficiency attained was 90% for 141 µm particles in the shaking table and 54% for 245 µm particles in the Falcon concentrator, both of which were used to treat the artificial feed.
