Part 1: Melting room

The function of the melting room of Taeantech High Vacuum granulator (HVGR) is to melt raw metal materials into molten metal. Different from the inferior molten metal obtained after melting metal without high vacuum protection in other merchants - molten metal has many bubbles, uneven melting and color segregation. Taeantech High vacuum granulator (HVGR) The strong combination of German high frequency heating technology + high vacuum protection + inert gas protection makes the molten metal without air impurity pollution, full melting uniform, no loss and no color segregation, is a high quality molten metal. High quality molten metal is the key to producing high quality finished metal granules.

High frequency heating: High frequency heating technology can rapidly heat up the inside of metal materials in a very short time, and the surface temperature is relatively low, and this special heating method from the inside out is twice faster than the ordinary heating method. This efficient heating method helps to improve production efficiency and shorten the working cycle. The German high frequency heating technology enables precise control of the heating process of precious metals by precisely controlling the frequency and intensity of the electromagnetic field. This precision allows the precious metal to melt evenly and completely, resulting in high-quality molten metal. High frequency heating process does not produce harmful substances, friendly to the environment. At the same time, due to the fast heating speed and high energy utilization rate, it is also in line with the environmental protection concept of energy saving and emission reduction.

Electromagnetic stirring: Electromagnetic stirring is based on the principle of electromagnetic induction. When an electric current passes through the coil, a magnetic field is generated, and the change in the magnetic field in turn generates an induced current in the metal melt. These induced currents are subjected to force under the action of a magnetic field, resulting in a stirring effect. In the process of high vacuum metal granulation, the metal melt will flow and mix violently under the action of electromagnetic stirring, and the fluidity and uniformity of the metal melt will be greatly improved. This helps to reduce the problem of composition segregation and uneven organization of precious metal granules, and improve the quality and performance of precious metal granules.

PID±1°C temperature control: PID intelligent temperature control system is used to precisely control the temperature in the melting furnace to ensure that the metal is melted within the best temperature range, while avoiding the loss of precious metals caused by exceeding the preset temperature shadow, and the metal melting is incomplete if the preset temperature is not reached. The PID temperature difference of Taeantech High Vacuum granulator (HVGR) configuration will not exceed ±1 ° C, far more than the temperature difference of ordinary temperature control system ±5 ° C -±20 ° C, so that the user of the machine in the process of precious metal granulation without any temperature concerns.

High vacuum protection: Taeantech High Vacuum granulator (HVGR) is equipped with German high vacuum technology - the original vacuum pump, which provides a safe and oxygen-free environment for the melting of precious metals and the casting of metal granules. In a high vacuum environment, the metal raw materials will not react with oxygen in the air during the melting process, thus avoiding the oxidation of the metal and improving the purity and quality of the product. The vacuum environment can effectively control the pressure and concentration in the atmosphere, which is very important to improve the granules quality and yield. In the granulation process, if the ambient gas is controlled at a lower pressure and concentration, the gas will escape more easily and the granules quality will be more uniform.

Inert gas protection: Inert gases (such as nitrogen, argon, etc.) can effectively isolate oxygen and prevent metal oxidation due to their non-reactive chemical properties. It can also precisely control the atmosphere in the melting room to avoid interference from other impurity gases. This control is essential to ensure the stability and repeatability of the metal melting and granulation process. Under the protection of inert gas, the pores generated during metal melting and granulation are greatly reduced.

Taeantech High Vacuum Granulator (HVGR) offers top of the line furnace vacuum protection and temperature control. Its efficient melting capacity and electromagnetic stirring function provide high-quality molten metal for the subsequent noble metal granulation process.

Part 2 Granulating room

The granulating room of the Taeantech High Vacuum granulator (HVGR) rapidly cools the precious molten metal to below room temperature by means of water cooling, allowing it to solidify quickly and maintain the desired shape and size. Rapid cooling and high vacuum protection technologies help eliminate thermal stress and crack generation inside precious metal granules.

High vacuum granulating room: When the precious metal is heated to the melting point in the melting furnace to reach the liquid state, the molten metal is uniform and without color segregation through electromagnetic stirring, and the molten metal flows into the casting barrel filled with cold water through the porous graphite mold, which is quickly cooled to form precious metal granules with high sphericity. The casting barrel is made of 304 stainless steel, with good sealing, corrosion resistance and stability. The good sealing of the casting barrel with high vacuum protection, but also can add inert gas protection, the final production of precious metal granules without bubbles, no pores, no cracks, smooth surface, bright color. Cooling water will not react with metal to produce harmful substances, in line with the environmental requirements of modern industry.

Direct connection of water pump: Taeantech High Vacuum granulator (HVGR) vacuum casting barrel is designed with a connection port for direct connection of water pump. When the metal melting is completed, the water pump is directly connected to the casting barrel, so that the casting barrel is quickly filled with cooling water for the cooling of the molten metal. The pump continuously circulates the upper water and the lower water to avoid the high temperature caused by water boiling and causing damage to the machine. This design saves manpower and improves work efficiency. Compared with other merchants' metal granulating machines, they can only pour a heavy bucket of water into the casting bucket manually, which is time-consuming and laborious.

Collection device: The metal granules collection device is located under the vacuum casting barrel. When the precious metal is cooled by water in a vacuum casting tank, the metal granules are temporarily slipped into the collection device.  Taeantech High Vacuum granulator (HVGR) has high granulation speed and large capacity, and can cast up to 100kg of precious metal granules at one time. The collection device can flexibly collect large mass metal granules in batches. Instead of waiting for 100kg of precious metal granules to be completed like the traditional collection method, it is difficult to carry heavy metal granules at one time.

Taeantech High Vacuum granulator (HVGR) granulating room fully considers the manufacture, cooling, protection, collection and other aspects of precious metal granules. It has the characteristics of high efficiency, environmental protection and easy operation. It is the core component of a high vacuum granulator capable of producing a smooth surface without any lines, high density, high quality precious metal granules.
