In the process of air granulation, there was a lot of power consumption for air blast. The complexity of structure and the great
Dry granulation is an attractive alternative to water quenching because of saving energy and reducing water consumption. In many dry granulation technologies, the hightemperature molten slag is atomized to slag particles, and the thermal energy from hightemperature slag particles is recovered by physical and chemical methods.
granulation tank for gold processing. Gold Alloy Granulation Mineral Processing Metallurgy. The gold to be parted must be approximately free from base metals, particularly from those which are not soluble in nitric acid, such as tin, arsenic, antimony. If these were present they would form insoluble oxides, which would remain with the gold ...
As a valuable byproduct of the ironmaking process, blast furnace slag with temperature up to 1450–1650 ° C contains a tremendous amount of sensible heat. Dry granulation and waste heat recovery via a moving bed is an attractive alternative to the conventional water quenching method due to energysavings and the reduction in water consumption.
