Supra Granulated Cork

Supra Granulated Cork

Supra granulated cork is an intermediate product between raw material and manufactured product.
After technical and chemical operations and top quality control, we obtain from these proceeds the most sophisticated products.

CHARACTERISTIC

Supra recycle and transform the cork wastes that proceeds of natural cork stoppers manufacturing into granulated cork.
Through a sequence of operations that requires permanent control raw material is transformed into granulated cork.
In this process, the key factors are granulometry, specific weight, humidity and purity.
the first step is to change raw materials, obtaining various sizes or dimensions, passing through a heated tunnel for total humidity extraction.
The next step is a strict selection of different granules obtained, taking into consideration the caliber (processed through screens with different mesh) and also purity and quality (through adjusted vibration and pneumatic suction). The lightest granules (without adding impurities) are easily sucked in by pneumatic action due to their specific weight and the uniformity of calibers.
