SAND CLASSIFIER WITH LONGITUDINAL HOPPER
Our vast experience in the sector enables us to offer ideal solutions for sand and organic matter removal.
Thanks to our longitudinal hopper, we can provide a wide range of sand separation solutions for industrial and civil depuration plants.
All our products are designed to last over time and aim to facilitate the operator as much as possible. For this reason, our company has always paid special attention to detail to deliver the most robust products.

MOD. SET1
Longitudinal hoppers are designed to classify and separate grit by gravity. Thanks to the swirling motion generated by a blower, the sand separates from the organic matter. The specific weight of organic matter is greater than that of water and as such, organic matter sinks to the bottom where a screw conveyor moves it to a collection pit. Finally, an inclined extractor screw removes the solids from the machine. The water, rich in organic substances, overflows and exits the unit through an apposite discharge outlet.
OPERATING PRINCIPLE
Effluent is conveyed by a feeding hopper where solids and particles sedimentation occurs. The screw conveyor lifts the sandy material out from the hopper and moves it to the discharge outlet. Once the sand is separated from the water, it is washed with clean water by means of a spray nozzle; the unclean water is conveyed back to the tank while clean sand continues to be lifted by the screw.
During the initial phase, before the sand is discharged from the machine, it is necessary to wait for the solid material to stratify on the channel. Once a “sand bed” of adequate size has formed, the equipment proceeds to discharge the solids.
