  • Tumbler is a treatment applied to dry pieces.
  • The goal is to give the pieces an aged look.
  • By means of a rotating cylinder, the pieces are struck against each other obtaining a more natural and aged appearance.
  • Tumbler is a post-drying treatment of the pieces.
  • Rotate and hit the pieces in order to obtain a more natural (aged) look.
  • The quality of the pieces will depend to a great extent on the proportion and the mixing of the aggregates.
  • If we combine the pieces with the Color-mix, the result will be even closer to natural stone.
TUMBLER process in steps
  1. The dry pieces enter the tube (tumbler).
  2. They travel their entire length as they rotate.
  3. Hitting each other breaks the tips and sides slightly.
  4. The goal is to get a more natural and aged look.
  5. If we combine Color-mix with the pieces, the final result will be like that of a natural stone.
  6. The quality of the pieces will depend to a great extent on the proportion and the mixing of the aggregates.
