The SSM-GVR100 is the flagship heavy-duty model in SanSong Melt’s industrial vacuum granulation system lineup, built with industry-proven German granulation technology and top-grade imported core components. Equipped with a 60KW high-power induction heating system and a 100kg standard gold processing capacity, it delivers ultra-high-efficiency large-batch granulation under full vacuum inert gas protection, completing a full melting and granulation cycle within 3–5 minutes per batch.
This model produces uniform, oxide-free spherical granules in 1.8–4mm size with ±1℃ high-precision temperature control, and comes with a built-in matched vacuum pump as standard. It is purpose-built for large-scale precious metal refineries, mega jewelry manufacturing groups, bulk electroplating material suppliers and industrial precious metal processing enterprises with high-volume continuous production demands. Our full product series covers 3kg to 100kg chamber capacities, with custom specifications, automated production line solutions and OEM branding services fully supported.
2. Working Principle
Load bulk precious metal raw materials into the hermetically sealed melting chamber. The system evacuates ambient air and fills high-purity inert gas to fully isolate oxygen, eliminating high-temperature oxidation and metal volatilization loss even for 100kg large-batch feeds.
The 60KW high-frequency induction heating system raises the material temperature evenly to a maximum of 1500℃, with ±1℃ temperature accuracy to ensure complete melting and homogeneous alloy composition across the full batch.
Fully molten metal flows through precision drip nozzles at the bottom of the crucible, forms evenly sized droplets under gravity, and drops into the closed circulating cooling water tank.
Droplets solidify rapidly into high-sphericity metal granules. The fully enclosed production process generates no dust, and cooling water operates in a closed loop to achieve near-zero wastewater discharge, complying with global green industrial production standards.
Finished granules are discharged directly via the bottom valve, ready for direct use in downstream large-scale industrial production and standardized delivery.
3. Core Features
Flagship Large-Batch Production Capacity: 60KW heavy-duty induction heating paired with 100kg gold capacity, finishes one full batch in 3–5 minutes, perfectly matching high-volume continuous industrial production and significantly improving daily output.
Stable Precision Temperature Control: Maximum working temperature of 1500℃ with ±1℃ control accuracy, ensures consistent melting performance for gold, silver, copper and various precious metal alloys under long-time full-load operation.
Premium Uniform Granule Quality: Standard granule size of 1.8–4mm with over 95% sphericity, smooth bright surface, zero oxidation and low porosity, requiring no secondary treatment and suitable for high-precision industrial batching.
Vacuum Protection for Maximized Yield: Integrated professional vacuum pump as standard configuration. For large-batch production, it effectively reduces precious metal volatilization and oxidation loss, bringing considerable material cost savings for enterprises.
Automated Reliable Operation: Intuitive integrated control panel with real-time temperature, vacuum and timing monitoring. Simple automated operation allows workers to master procedures quickly, supporting long-time uninterrupted mass production.
Full Customization Support: Full range of standard chamber capacities available; supports custom nozzle sizes, parameter adjustment, automated production line upgrading, OEM private branding and custom logo printing.
