This plant has been realized to treat 50 tph of 0 – 60 mm sand and gravel coming from several excavation sites.

The fist rinsing screen, equipped with flow diverter installed into the front chutes, is able to select the following three fractions:

• the slurry including the particles < 4 mm, that is sent to the sand compact plant equipped with pump and hydro – cyclones to remove the silt and clay
• 4 – 32 mm that can be sent to the second dry screen, or it can be stocked on pile together with the fraction 0 – 4 mm in order to create a mixed product 0 – 32 mm
• 32 – 60 mm that is stocked on pile

When the second dry screen is fed with the fraction 4 – 32 mm, the other three final products required from the batching plants are produced:

• 4 – 8 mm
• 8 – 16 mm
• 16 – 32 mm
