For high-capacity foundries, instead of using waste sands in different sectors, it is the most logical way to set up this system and turn these waste sands into a value.
The reason for this is that when these sands are qualified as waste, they come out of the foundry free of charge and even by paying costs (transportation, landfill expenses, etc.).
If the foundry installs this system on its own, new sand inputs will decrease at high levels and it will become a completely value-added process.
Foundries place the product core into the green sand mold during the molding process.
This core sand mixes with the other sand in the demoulding system.
The more core sand enters the foundry sand system, the more sand it must expel from the system.
If the green sand recycling system is located in the factory, this sand will not be thrown and more suitable sand will be obtained than the new sand characteristic.
The sands obtained in the green sand recovery process become to be used in the core.
