8kg High-Efficiency Vacuum Granulator Precious Metal Granulation Equipment For Refining & Recovery Plants
Product Introduction
1. Product Overview
The SSM-GVR8 is a medium-to-large capacity vacuum granulating machine in SanSong Melt’s granulation system series, engineered with German granulation technology and imported core components. Equipped with 20KW high-power induction heating and a standard 8kg gold processing capacity, it delivers stable and efficient batch granulation under vacuum inert gas protection, completing one full melting & granulation cycle in only 3–5 minutes.
This model produces smooth, oxide-free spherical granules in 1.8–4mm size with ±1℃ precise temperature control, and includes a built-in vacuum pump as standard configuration. It is an ideal choice for medium-sized jewelry factories, precious metal refineries and electroplating material suppliers with medium-to-high volume production demands. Our full product series covers 3kg, 4kg, 5kg, 6kg, 8kg, 10kg, 20kg, 50kg and 100kg capacities, with custom specifications and OEM branding services available.
2. Working Principle
Load precious metal raw materials into the sealed melting chamber. The system evacuates air and fills high-purity inert gas to fully isolate oxygen and prevent high-temperature oxidation.
The 20KW high-frequency induction system heats the metal evenly up to 1500℃, with temperature accuracy controlled at ±1℃ to ensure complete melting and uniform alloy composition.
Fully molten metal flows through precision drip nozzles at the bottom of the crucible, forms evenly sized droplets under gravity and falls into the circulating cooling water tank.
Droplets rapidly solidify into high-sphericity metal granules. The fully enclosed structure generates no dust, and cooling water is recycled to achieve near-zero wastewater discharge.
Finished granules are discharged directly from the bottom valve, ready for downstream production and processing.
3. Core Features
High-Power Efficient Production: 20KW induction heating with 8kg gold capacity, completes one batch in 3–5 minutes, perfectly matching medium-to-high volume continuous production.
Precise Temperature Control: Max. 1500℃ working temperature with ±1℃ accuracy, ensures stable melting for gold, silver, copper and various alloys.
High-Quality Uniform Granules: Standard 1.8–4mm granule size with over 95% sphericity, smooth and bright surface, zero oxidation and low porosity, no secondary treatment required.
Vacuum Protection & Low Material Loss: Built-in matched vacuum pump as standard, effectively reduces precious metal volatilization and oxidation loss, maximizing raw material yield.
Automatic & Easy Operation: User-friendly control panel with integrated monitoring, plug-and-play design. Workers can master full operation after simple training.
Flexible Customization Options: Multiple standard capacities available; supports nozzle size customization, OEM private branding and custom logo printing on machine body.
Built-in vacuum pump, imported core parts, German granulation technology
Note: The above parameters are for reference only. Customized specifications are supported. Please contact our sales team for detailed technical solutions and quotations.
5. Application Fields
