There are many different ways to sort rock after blasting. Some methods are much more labour-intensive, but all will eventually get the job done.

The least efficient way to screen all of that blast rock is to dump loader buckets full of material onto a stand-alone stationary grizzly. Not only is it hard work, but it takes a very long time to complete.
Traditional rip rap plants rely on grizzly bars and step-deck grizzly feeders to separate and sort rock by size. The third method is to use a heavy-duty rock trommel screen.

Trommel's use a large rotating drum with different size screen openings to sort material. The drums contain different sections fitted with different size openings to sort multiple rock sizes.

Trommels' ability to clean wet, stick material or clay-bound rock sets them apart from other riprap plants.
