Gold Granulation

• The PLC control system and observation window allows you to properly monitor the melting and gold granulation process.
• The vacuum gold granulation requires about 15kw to 25kw of power. This implies that there is no requirement for heavy power usage before the vacuum granulator can work.
• Melting and granulation is done under a protective environment with the use of protective gas such as argon.
• The maximum melting temperature of the vacuum gold granulation is 1600 degree celsius. Melting is complete within 5 to 6 minutes, therefore, the entire process of gold granulation is less than 10 minutes. This however contributes to a fast production process.
• The PID controller present in the vacuum gold granulation is responsible for automatic regulation of the melting temperature, speed of melting, pressure, flow, etc.
• Superbmelt vacuum gold granulation is capable of casting the following metals into granules: gold, K-gold, silver, copper, brass, bronze and their alloys.
• The casting system is done under vacuum, this means that all heat generated for melting is used only within the melting chamber, that is no escape of heat that can lead to energy wastage. The vacuum system also prevents contamination of the granules.
• All granules cast with the vacuum granulator are smooth, evenly shaped, good colour and no oxidation.
• The vacuum granulator equipment is equipped with a water tank that prevents the granules from sticking together during the granulation process, so that each granule can stand on its own.
• The induction system allows for homogenization of molten metal due to the stirring effect of the magnetic field which works while melting is on within the crucible.
• The water in the tank alongside the powerful chiller keeps the temperature and the granules under control in order to obtain quality granules.
