Rotor granulator AFI-05plus

for metalscompact

The devices are used in the production of gold and silver grain in the precious metals recycling industry and metallurgy laboratories. The smaller AFI-03plus model enjoys great popularity - in this model the ratio of generator power to the crucible capacity ensures instant melting of the full input in approximately 1-2 minutes. Granulating furnaces are devices based on the basic models AFI-03 and AFI-05. Additional equipment of the furnace allows pouring the metal through the hole in the bottom of the crucible. When using crucibles with a strainer in the bottom or one hole of large diameter, one can make grain or cast metal for vertical ingots. In the case of the production of pure metal grain, i.e. when it is not necessary to mix several alloy components, non-stop granulation is possible, with a constantly raised stopper opening the bottom of the crucible. An undoubted advantage of bottom drain casting is the difference in the densities of metals and impurities present in them. As soon as the metal passes into the liquid phase, the impurities flow to the surface. When pouring metal from the so-called "hand" these pollutants get into molds and are closed in the structure. By pouring the metal through the hole in the bottom of the crucible, the impurities remain in the crucible or pollute only the entrance of the die. Both granulators also have the functionality of induction furnaces AFI-03 and AFI-05, respectively.
