Portable screening attachment is designed for earthmoving, construction, demolition, public works, recycling and mining industries. The Australian-made attachment is a two-part bucket similar in size and shape to an earthmoving bucket with no internal moving parts. Material is sieved out through a mesh screening chamber as the FlipScreen rotates. Larger particles are retained inside by the unit’s inward spiraling action. Counter rotating the bucket ejects all the remaining oversize. The FlipScreen is capable of screening 660 tons of material per day, and can be fitted to 20 to 27.5 ton excavators.
