Construction Features
The sand classifier consists of a large conical hopper that utilizes the Coanda effect to promote settling, sedimentation, and washing of the sands. It also includes an auger for transporting and dehydrating the collected material.
The unique conical shape of the hopper with the Coanda effect and the special counter-washing system at its base, along with the slow-rotating internal agitator, enable the machine to wash the sands and separate them from organic substances. The machine is completely sealed with gaskets and covers to prevent the release of odors and contaminants.
Advantages
Advantages include reduced installation, operating, and maintenance costs:
Additionally:
- No mechanical parts in contact with the product.
- Absence of intermediate and end supports.
Options
Constructed in AISI 304 or 316 stainless steel with the possibility of sand washing before discharge.
Accessories
- On top of the hopper, there is a flanged loading spout through which the material to be treated is introduced into the machine.
- The unique conical shape of the hopper and the movement system using a slow-rotating agitator create a vortex that facilitates washing and sedimentation of the sands.
- Heavier sand particles settle at the bottom of the hopper, where a counter-current system allows for washing. Subsequently, the washed material reaches the auger connection spout, and on the side of the hopper, a dedicated discharge spout allows for the evacuation of lighter organic matter.
- The auger at the bottom of the machine is capable of extracting, dehydrating, and lifting the collected material toward the discharge mouth to convey it into a container.
