Diamond Bruting Machines - Centering System Model:MDBM-200

 

This is a planning cum centering machine for fancy shaped Diamond bruiting.

The rough makeable Diamond with tentative table will be glued to the die pot, which will fix in a special three-piece Diamond pot assembly. This pot assembly will be mounted on the machine spindle.

The centering machine will first perform the planning process on the rough Diamond and suggest the various possible shape and size of the finished Diamond from the rough. It will also indicate the possible selling price of each of the finished Diamond based on the international price data. The operator can decide for one of the alternative suggested by the centering machine.

Then the centering machine goes into centering mode where the centre of shape generating curve will be defined. The operator will set the three-piece pot assembly as suggested by the machine. This pot assembly will now be removed and fixed to the fancy brute spindle.

This centering machine will help in optimization of finished Diamond size and maximization of value recovery. And also make it possible to reduce production cost, by making use of low cost fancy bruter for semi bruiting as per the plan. Shapes: Marquise, Pear, Oval, etc. Three piece pot system. Instant display of possible selling price of finished stone. Minimizes production cost of Bruiting fancies. Optimization of finished size.

DIAMOND PROCESSING AND SORTING

diamonds classified forshipment After diamond ore is mined it is transported to a processing plant where it is first fed into huge crushing machines. In the old days diamonds were recovered on vibrating greased tables. After the diamond ore was crushed it was mixed with water and slid down the table. Because of their surface properties, rough diamonds adhere tenaciously to the grease while other materials vibrate on through.
