Vacuum Granulator

Vacuum metal granulators are used to granulate various precious metals such as gold, silver, copper and alloys. It works by first heating the metal material to its melting point in a vacuum chamber, then passing through a multi-hollow crucible as a current breaker, and finally flowing into a circulating water groove to cool into regular metal particles without oxidation.

SuperbMelt vacuum metal granulator performs smelting work under the environment of full vacuum inert gas, and is equipped with an electromagnetic automatic stirring device, so that the finished product of the metal particles can not be oxidized and has uniform spherical shape and luster.

It is most commonly used in precious metal refinery and jewelry manufacturing plants with high quality requirements.

    How to Choose a Suitable Vacuum Metal Granulator?

    Material Type

    The type of metal you will be processing will impact the type of metal granulator you need. Some granulators may only be suitable for certain metals, such as aluminum or copper, while others can handle a wider range of materials.

    Capacity

    Consider the volume of material you will be processing and choose a metal granulator that can handle the required capacity. For example, 24K Gold: 5-20 kg and 925 Silver: 2.5-10 kg.

    Energy Efficiency

    Consider the energy consumption of the granulator, as well as the cost and availability of the power source.

    Maintenance Requirements

    Consider the ease of maintenance and replacement of wear parts, as well as the availability of spare parts. Our vacuum metal granulator is designed in one piece for easy maintenance.

    Price

    The cost of the granulator is an important factor, but it should not be the only consideration. The most expensive option may not be the best choice if it does not meet your specific needs.

    Comparison between Vacuum Metal Granulator and Non-vacuum Granulator

    vacuum metal granulator vs non-vacuum metal granulatorVacuum metal granulators and non-vacuum metal granulators are both used for the process of granulating metal scrap into smaller particles, but they have some differences in terms of their structure, operation, and applications.

    Structure

    Vacuum metal granulators typically have a more complex structure compared to ordinary granulators, as they are designed to operate under a vacuum. This helps to reduce minimize the oxidation of the metal being processed. Ordinary granulators, on the other hand, do not have a vacuum system and may be more straightforward in design.

    Operation

    The operation of vacuum metal granulators is more controlled and precise compared to ordinary granulators, as they are designed to minimize the oxidation of the metal being processed and prevent the formation of dust. Ordinary granulators, on the other hand, may produce oxidation during the granulation process.

    Energy Efficiency

    Vacuum metal granulators tend to be more energy-efficient than ordinary granulators, as they are designed to operate under a vacuum and thus require less energy to granulate the metal.

    Application

    Vacuum metal granulators are typically used in applications where a high degree of metal purity is required, such as in the recycling of electronic waste or precious metal scrap. Ordinary granulators may be more suitable for less demanding applications, such as granulating metal scrap for use in other manufacturing processes.

      FAQ Guide of Vacuum Metal Granulator

      Vacuum granulating machine is what you need to invest in when looking to make some fine gold, silver or other granules of precious and non-precious metals. Suppose you are looking for some of the most frequently asked questions about the vacuum granulating machine, then you have come to the right place.

      In this piece, we have tried to be as comprehensive as possible with our responses about the vacuum granulating machine. However, if you have a question that you feel we have not addressed in this piece, be sure to let us know in the comments. Our experts will make sure you get the most professional response possible.

      1. What does the term granulating means when working with gold?

      When granulating gold with vacuum granulating machine, you will be using our machine to turn your gold into grains that you can easily handle work. With the machine, you will get high quality and homogenous grains. Once you have the grains, you will pour them into a water tank with the help of a multi-hollowed crucible.

      There are so many things you can do with the grains. Remember, you will have to begin from the raw material that has been molten with the help of induction heating. If you ask any jeweler, they will tell you that the master grains must have certain level of quality to meet the industrial standard.

      However, the machine we have at Superbmelt is best for alloys and metals that have been easily oxidized. Note that you don’t have to be the best jeweler to know what clients or customers are looking for when producing the master grains and alloys.

      2. How do you do gold granulation?

      Granulation might be an old process, but the machines used to complete the process have undergone major transformation. With the help of technology, Superbmelt has formulated a powerful induction furnace that you can use to complete the granulation process. Provided you have the right materials, granulation should not take a lot of your time to complete.

      To begin the process, take your induction furnace and put the crucible in place. Remember, the crucible should be made of a material with a higher melting point compared to that of gold. Unless you do that, you the crucible will melt and the granulation process will not be successful one.

      Place a large piece of gold on the crucible and turn on your induction furnace to commence the heating process. Heat the gold to its melting point and right below the crucible, there will be some holes. Your liquid gold will go through the hold at the bottom of the crucible to drop inside water.

      Since the water is cold, it will force the liquid or molten gold to form granules. Note that our induction furnace will complete the process in a matter of minutes based on the amount of gold you are trying to melt.

      3. How to choose the right non-ferrous metal melting furnace?

      Would you like to have the best non-ferrous metal melting furnace? There are things you must have in mind before you begin looking. For instance, when you want the best, think about its power efficiency.

      It is vital to consider using our induction furnace or vacuum granulating machine since it comes with a wide range of features for the most pleasurable application process. It does not consume a lot of power and is also perfect for environment.

      Our induction furnace doesn’t require a lengthy learning curve to operate. If you choose our induction furnace, you will save a lot of money since it doesn’t consume a lot of power.

      4. What can you use as a crucible for non-ferrous metal melting?

      Graphite or silicon carbide are the best materials to use for crucible meant for heating non-ferrous metals. If you are not sure why that is the case, silver and gold have very high melting points.

      Silicon carbide and graphite have melting points of around 1600 degrees centigrade. If you heat up to that level, you shall have melted most of your gold. You don’t have to keep heating your non-ferrous metal to 1600 because they have way lower melting points.

      But if you must heat metals with melting temperatures higher than 1600 degrees centigrade, then you might have to reconsider the material used to make your crucible.

      5. Can you melt gold and silver off electronics?

      Yes, just like you can remove gold and silver from their natural ores, you can easily get them off electronics. The problem with this technique is that you will spoil the electronics, but it makes sense if you all you need is to get silver and gold from electronics.

      6. What Kind of Metal Granulation can the Machine Make?

       Gold, Silver, Copper, and their Alloys.

      7. What is the Melting Capacity of the Machine?

      24K Gold: 5-20 kg and 925 Silver: 2.5-10 kg.

      8. What Consumables Need to be Prepared for a Long Time?

      Graphite crucible, graphite mold and stopper.

      9. What Particle Size can be Achieved?

      Can make 2-5mm metal particles.

      10. How Long is the Lead Time of the Machine

      30 days.

      11. What is the Footprint of the Machine

      2x5m.

      12. What Type of Gas can be used?

      Argon and nitrogen.
