Juyi Precious Metal Granulator / Granulating Machine is a specialized equipment used to melt precious metals such as gold, silver, and copper, and then transform the molten metal into small, uniform granules. It plays a critical role in refining, alloy production, and jewelry manufacturing by converting scrap or bulk metal into manageable granulated form.

⚙️ Working Principle:
1. Metal Melting:
• The machine uses induction heating to melt the input metal inside a graphite crucible.
• The PID temperature controller for precise temperature control is optional.
2. Inert Gas Protection (Optional):
• Some machines include an argon or nitrogen gas chamber to create an oxygen-free environment, preventing oxidation and improving the color and quality of the granules.
3. Electromagnetic Stirring (Optional):
• Before pouring, electromagnetic stirring may be applied to make the metal composition more uniform, ensuring consistent granule quality.
4. Granulation Process:
• The molten metal is poured through a sieve or nozzle directly into a cooling tank filled with circulating water.
• As the metal drops hit the water, they rapidly solidify into spherical or near-spherical granules.
5. Cooling and Separation:
• The water cools the metal instantly, and the resulting granules settle at the bottom of the tank.
• The water is drained or filtered to collect the granules, which are then dried and stored for further use.
Key Features:
• Induction Heating Technology
Fast, efficient, and clean melting with stable temperature control, ensuring consistent quality in each batch.
• Stainless Steel Cooling Tank with Water Circulation
Molten metal is poured into a water-cooled granulation tank through a special nozzle, quickly solidifying into round granules.
• Electromagnetic Stirring (Optional)
Keeps the molten metal uniformly mixed to avoid segregation and improve granule consistency.
• User-Friendly Interface
Simple controls and easy operation allow both experienced operators and new users to work efficiently.
• Compact & Durable Design
Built with high-quality components, the machine offers long-lasting performance with minimal maintenance.
Typical Applications:
• Recycling scrap metal into reusable granules
• Preparing metal for alloy blending
• Jewelry casting and refining processes
• Precious metal storage in standardized granule form.
Precious Metal Granulator is a reliable and efficient system for transforming molten precious metals—such as gold, silver, copper, and their alloys—into uniform metal granules. Ideal for jewelry manufacturers, metal refiners, and casting workshops, this machine helps streamline the process of preparing metals for further melting, alloying, or refining.
