1. The vacuum precious metal granulator is a high-end equipment that melts precious metals and makes them into granules in a vacuum environment. It combines vacuum technology and granulation technology, and is particularly suitable for the processing of high-purity precious metals (such as gold, silver, platinum, palladium, etc.).
2. The machine heating power supply adopts a power module imported from Germany. IGBT (insulated gate bipolar transistor) variable frequency heating is an efficient heating method based on power electronics technology. Its core principle is to convert industrial frequency AC into controllable medium frequency AC through the high-frequency switching characteristics of IGBT, and then use electromagnetic induction or dielectric loss effect to achieve heating
3. Equipment Overview
Definition: The vacuum precious metal granulator heats and melts precious metals in a vacuum environment and makes them into granules to ensure the high purity and quality of the metal.
Core features: The vacuum environment prevents oxidation, electromagnetic induction heating is efficient and energy-saving, and the granulation process is automated.
Application areas: Widely used in jewelry, electronics, semiconductors, chemicals and other industries for the recovery, refining and granulation preparation of high-purity precious metals.
4. Working principle of our equipment
Vacuum environment:
Melting and granulation are carried out under vacuum conditions to prevent metal oxidation and ensure high purity.
The vacuum environment can also effectively remove impurities and gases in the metal.
Heating method:
Electromagnetic induction heating technology is used to generate an alternating magnetic field through high-frequency alternating current, so that eddy currents are generated inside the metal, thereby quickly heating and melting.
Granulation process:
The molten metal is formed into small droplets through atomization or dripping technology, and is cooled and solidified into particles in a vacuum or inert gas environment.
The particle size can be adjusted by equipment parameters (such as atomization pressure, rotation speed, etc.).
5. Advantages of our equipment
High purity: The vacuum environment prevents oxidation and contamination, ensuring the high purity of metal particles.
Energy-saving and high efficiency: Electromagnetic induction heating directly acts on the metal, with high thermal efficiency and low energy consumption. Frequency conversion heating reduces energy transmission loss, and the thermal efficiency can reach more than 90%.
Precise temperature control: Siemens control system is used to achieve high-precision temperature control through frequency adjustment. The temperature control is accurate to ±0℃, ensuring uniform metal melting and avoiding overheating or underheating.
Automated operation: high degree of automation, reducing manual intervention and improving production efficiency.
Environmental protection and safety: no open flame, no smoke, in line with environmental protection requirements, safe operation.
Uniform particles: uniform granulation size, suitable for subsequent processing and application.
Cooling system: quickly cool and solidify the cut particles through water cooling or air cooling to ensure the stability of the shape and size of the particles.
6. Our equipment can be customized according to customer requirements.
Power: provide equipment with different powers according to customer needs (such as 10kW, 20kW, 50kW, etc.).
Heating frequency: high-frequency induction heating, rapid melting of metal.
Vacuum: the vacuum level that the equipment can achieve (such as 100Pa or higher).
Production capacity: the amount of metal processed per hour (such as 1kg/h, 5kg/h, 100kg/h, etc.).
Particle size: adjustable particle size range (such as 0.1mm-5mm).
Cooling method: vacuum or inert gas cooling.
