Granules are divided into two general categories, each of them has a different use
1. Corn granules: which are used as media for vibrating dryer machines. These granules are prepared and produced in different sizes, which are selected depending on the needs of customer and their parts. Corn granule, with its water absorbent ability, in addition to absorbing the moisture of the parts, cleans all the surfaces of the parts and prepares them for the next process.
2. Walnut granules: These granules are used as a polishing media for parts (especially ornaments and precious metals). This granule is produced in different sizes depending on the needs of the customers, just like the corn granules.
