General information

The environmentally-friendly dry-type polishing machine is designed to grind and polish products with high value, high-quality requirements, and flawless mirror-like surfaces.

It is a barrel tumbler mass finishing machine.

This dry-type smoothing machine is made of bamboo and wooden barrels. The abrasives used are wood particles, walnut shells, and olive shells. It has no pollution and no emissions which is why it’s safe for the environment.

Eight hangers can be placed in the barrel, and several products can be installed on each hanger (depending on the size of the product). There is a gap between each product. Because each product is fixed on the hanger, it will not collide when tumbling.
