[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!

Feature

1：The metal granulator comes With argon protection system, which minimize the oxidation in the process of metal melting and casting

2: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.

3: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

4: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.

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