Metal Granulating Machine For Gold Silver Copper Graining Making
How To Make Gold Silver Copper Granules – CDOCAST Metal Granulating machine
What Is Metal Granulating Machine
Metal granulating machine is a machine used for producing various metal granules such as gold, silver, copper, etc. It is widely used in jewelry, scrap metal recycling, refining and other fields. The metal granulator combines metal melting with granulation to produce metal particles such as gold, silver, copper, etc. It can achieve the manufacturing of 5 kg to 300 kg of metal granules.
Metal materials are melted into a liquid state through melting, and then the liquid metal flows into a mold with holes and is cooled by water to form irregular metal granules. Different sizes of granules can be obtained by the size of the mold aperture.
The Advantages Of Metal Granulating Machine
- The metal granulator is used to produce high-quality precious metal particles and alloy particles with uniform colors. The surface of the finished particles has no oxidation, high density, and no pores, especially good sphericity, uniform particles, and stable color.
- Adopting the most advanced IGBT intermediate frequency induction heating technology, the melting speed is fast. PID technology can achieve precise temperature control and improve the quality of finished products.
- The maximum melting temperature can reach 1600℃, and PLC control system can be used. It can be operated through a touch screen, with simple buttons and more convenient use, and clear parameter settings.
- Equipped with an inert gas protection system, it minimizes metal melting and oxidation during the casting process, especially suitable for precious and alloy metals that are prone to oxidation. It also reduces the loss of metal smelting and extends the lifespan of the crucible.
- By adopting the separation arrangement of the material box and the water tank, the material can be easily collected and obtained when the granulation is completed.
- The mold is a porous design, installed at the bottom of the crucible to cast the molten metal into particles, and the granulation speed is faster.
- Use dedicated cooling water to prevent metal particles from adhering to each other, making particle formation more uniform.
- A detailed and complete self-diagnosis system and protection functions ensure a low equipment failure rate.
- It has the function of automatic frequency tracking, making the melting process more stable and safe. During work, there is no noise and the granulation time is shorter, greatly improving production efficiency.

The following are different models of CDOCAST metal granulators:
1. Small Metal Granulation tank
This is our simplest model, consisting of a melting furnace and a metal granulation tank. Melting and granulation are carried out on different equipment. If you have a melting furnace, you can buy only one granulation tank. It mainly consists of a stainless steel water tank, a water pump, and a gas spray gun. The operation is simple, just use a small melting furnace to melt the metal, and then pour the liquid metal into the graphite crucible on the granulation tank to make particles. Please note: We need to heat the crucible on the granulation tank to prevent metal from cooling and blocking the holes at the bottom of the crucible. Typically, this small granulation tank has a capacity of 1kg-5kg. The particle size produced by this metal granulation tank is usually irregular.
2. 1-4kg Small Metal Granules Casting machine
This Metal Granulating machine is an integrated type granules-making machine that has the function of melting and granulation. It’s suitable for making 1 – 4 kg of gold, silver, and copper grains. It mainly consists of the water tank, graphite crucible, thermocouple, operation panel, and power supply. After finish melting, the molten metal will flow down to make granules. This small granulator is very suitable for small refineries and Jewelers.
3. 4-12 KG Gold Silver Copper Granulating Machine
This Model Metal Granulating machine is designed for making 4-12 kg gold, silver, and copper grains. It looks similar to the last model, but with one very big difference: it’s equipped with a protective gas device, which proves uniform granules, stable color, and no bubbles. And it comes with a lid of the melting chamber to prevent liquid spillage. The integrated design can reduce the cable connection between too many power cabinets and granulation parts, and reduce many unnecessary safety hazards.

It has a graphite plug on the top of the melting chamber. When starting the melting, move the graphite plug to block the crucible hole. After finish melting, press the side switch, and lift the graphite plug, and the liquid metal will flow down and start granulation. Besides, it is equipped with a heightened stainless steel water tank and automatic loading tray. Install the loading tray and press the side switch, the loading tray will automatically lift, which is more convenient. Because of the large melting capacity of this granulator, there must be a large enough water tank （The water tank designed by us is at least 1m high）to avoid the water temperature rise and metal particles Sticking to each other caused by long-time grains making, With the increase of Grains making capacity, it is also necessary to consider whether the operation of workers is convenient. Therefore, we have designed an additional automatic loading tray lifting, thus, There is no need to manually lift the material Tray filled with metal particles, which provides great convenience for workers’ operation.
