[How to make silver,gold grains?- metal granulator]

The metal granulator produced by CDOCAST is applied to produce various metal  grains, such as gold, silver, K gold, copper, etc. The metal granulator includes three parts: the furnace, the water tank and the loading frame.

The molten metal will flow through the pure graphite comes with multihole at the bottom , and The whole granulation process is protected by inert gas argon or nitrogen, which minimizes the oxidation of metal.

The gold granulating machine & silver granulating machine are the most commonly used models. CDOCAST metal granulator is equipped with an argon flow protection device. During the melting &granulation process, argon protection will be injected to prevent the oxidation of precious metals to the greatest extent. while if  the customer plan to cast K gold grains, then we will recommend using vacuum granulating machine  to prevent oxidation. click here to get more information about the vacuum metal granulator.

CDOCAST can customized different metal granulator  for customers according to different metals ,different capacities, and different production efficiency for each client, welcome to inquiry us now!

1: The granulator is used to produce high-quality precious metal particles and alloy particles with uniform color. The finished beads have no oxidation, high density and no pores, especially good spherical surface, uniform particles and stable color.

2: The metal granulator comes with Inert gas protection system, which minimize the oxidation in the process of metal melting and casting, especially suitable for precious metals and alloy metals that are easily oxidized. It also reduce the loss of smelted metal and increase the life of the crucible.

3: Applied with the Intermediate frequency induction heating technology, rapid  melting speed, it takes about 15 minutes to melt one batch, and the casting time is about 15 minutes, which means that you will get high-quality metal grains within half an hour.

4: The temperature can reach 1600°C, the granulation time is 20-30 minutes once, and the melting and granulation are completed in one. After the casting is completed, the pelletizing barrel is easy to take out.

5: Pure graphite crucible comes with quartz jacket as protect, the multihole design at the bottom can act as breaker to make the molten metal  cast into grains, what is more, It only takes 5 minutes to replace new crucible which is very convenient for the operator

6: Special cooling water to prevent adhesion of metal particles and make particles more evenly formed.

7: Metal granulator melting chamber and water tank can be designed separately or as an integrated unit, if there is not enough space for the user, we will  recommend the integrated unit, which takes up less space.

8: The detailed and complete self-diagnosis system and protection function ensure that the equipment failure rate is low.

9: After the melt is completed, the casting speed is fast, making the metal particles smooth and smooth without sand holes.

10: CDOCAST provide 2 years of after-sales service, which minimizes customers’ concerns about after-sales service.

Graphite crucible can be customized to suit different needs, the porous design of the bottom acts as a crusher to cast the molten metal into pellets
