The AMKCO "Auxiliary Systems" vibratory separator provides the opportunity to increase the screen surface of an existing machine or to install a vibratory separator that requires relatively small floor space compared to the available screen area.

In an AMKCO AS machine, a screen with a smaller diameter is placed above the usual screen. This not only increases the surface area of the sieve greatly, but because the first (smaller) screen can also be put to maximum use, the largest part of the total capacity is sieved on this screen.
