Granulated Cork
Jul 23, 2017


Granulated cork is basically an intermediate product between raw material and final product, subsequently, from these proceeds are obtained the most sophisticated products, under various strict chemical operations and first class quality control, using the most modernized and up-to-date systems.


We has a modern and sophisticated up-to-date system for turning raw material (cork wastes), which is the proceeds of natural cork crafts  manufacturing, principally the cork floor tiles , cork wall tilesroll of cork, etc…,into granulated cork. In the making of granulated cork, a sequence of operations requires permanent control for which we’ve a special “research laboratory”, with its technical know-how and a perfect quality control procedure of the most important factors, such as: granulometry, specific weight, humidity, purity, etc.

Crushing through a complementary milling process, changing raw materials, becomes the first phase, obtaining various sizes or dimensions, passing through a heated tunnel for total humidity extraction, therefore, a very low content is obtained complying with international rules.

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, with uniformity of calibers.
