CHEMICAL BRIGHTENING (BOMBING)
The chemical brightening (bombing) plants provide a chemical brightening process for goldsmith manufactured pieces through a reaction between hydrogen peroxide (H2O2) and potassium cyanide (KCN).
The reaction takes place under a fume hood and in complete security.
The unit is designed and manufactured to meet the various production needs: the reactor is suitable for processing both small and big batches.
The plant is equipped with a storage tank with filtration system for the effluents that allow to gather the liquids for a later recovery of the precious metals dissolved in solution.
MAIN FEATURES:
- Versatile: for gold alloys 14 - 18 - 21 kt; for silver; for brass
- Safe working;
- Minimal precious metals removal;
- Precious metals recovery at a later step.
The new version of the machine is integrated with a PLC and touch screen display for setting the working parameters.
The system can be equipped with the "Industry 4.0 Module" which enables the user to check the working parameters and remotely control them.
Information that can be exchanged between the machine and the company IT system (4.0 integration) are:
- Number of cycles per day
- Infrmation on each single batch
- Trend of the operating parameters
