T-Grains

T-Grains is an automated system designed to produce gold and silver grains of the highest quality, eliminating the risks and slowness of manual work. A key element of the system is the layout of the plant, which prevents the metal from cooling as it passes through the granulation tank. This is made possible by the presence of a heated casting die, equipped with a dedicated inductor. This ensures that the temperature of the molten metal remains constant, preventing production defects. Another advantage is the minimisation of the exposure time of the molten metal to oxygen in the air, a crucial factor in achieving a perfect quality shot. In addition, the temperature of the water in the granulating tank, which is decisive for the final quality of the grains, is controlled by a cooling system connected to a recirculation pump. This system maintains a constant water temperature in each granulation batch, ensuring uniformity in the process.
