20kg Precious Metal Granulating System 30KW 380V Induction Pellet Equipment support OEM

1. Product Overview

2. Working Principle

1. Melting & Constant Temperature Control
    
   Put gold, silver, copper or alloy raw materials into the crucible. The built-in high-frequency induction heating unit rapidly melts metals, while the ±1℃ closed-loop PID temperature controller stabilizes molten metal temperature.
2. Optional Argon Anti-Oxidation Treatment
    
   Turn on the optional argon protection system to fill the sealed heating chamber with inert gas, isolating air oxygen to avoid dark oxidation spots on metal pellets and reduce crucible wear.
3. Water Cooling Spherical Pellet Forming
    
   Homogenized liquid metal flows through precision nozzles and drips into the matched circulating water cooling tank. High-temperature metal droplets instantly cool and solidify into standard round precious metal pellets.
4. Finished Pellet Collection
    
   Once the granulation cycle finishes, you can directly collect the finished spherical pellets for subsequent lost-wax jewelry casting or alloy research tests.

3. Core Product Features

1. Complete Capacity Range for All Production Scenarios
    
   Full series covers 2kg–150kg gold equivalent models, from lab small-sample test machines to medium industrial granulation equipment, one series meets all your output needs.
2. ±1℃ Ultra-precise Constant Temperature Control
    
   Advanced PID temperature control module limits temperature fluctuation within ±1℃, ensures consistent fluidity of molten metal, uniform pellet dimension and low defective rate.
3. Optional Argon Inert Gas Protection Module
    
   Customizable argon shielding device cuts precious metal oxidation loss during melting, extends crucible service life and lowers long-term consumable replacement costs.
4. Full Water-cooled Heating Chamber & Cover
    
   Whole heating cavity and cover adopt circulating water cooling design, effectively dissipating heat during long-hour continuous operation without overheating shutdown.
5. Mature German Granulation Craft + Imported Core Parts
    
   Adopt proven German granulation technology; all key electrical, pneumatic and control components are imported top international brands, delivering stable operation and ultra-low failure rate.
6. Compact Integrated All-in-one Structure
    
   Machine host and cooling water tank are split matched design, occupy small workshop space; touch control panel with simple operation logic, easy daily cleaning and maintenance.
7. Wide Material Compatibility
    
   Perfectly process gold, silver, copper and all types of precious metal alloys, applicable for jewelry raw material production and metal alloy lab research.
