Granulation

Granulation is the process of forming grains or granules from a powdery or solid substance, producing a granular material.It is applied in several technological processes in the chemical and pharmaceutical industries. Typically, granulation involves agglomeration of fine particles into larger granules, typically of size range between 0.2 and 4.0 mm depending on their subsequent use.

Granulation of molten slag for heat recovery

Jul 31, 2002· (3) Sulfide is emitted from the slag into an air by the water quenching. (4) A post process for drying slag is a must after the water quenching. (5) The thermal energy of high temperature slag is wasted without recovery. To solve these problems, we studied the dry granulation of the molten slag by rotary cup atomizer (RCA).

Dry Granulation of Blast Furnace Slag

Dry slag granulation process is essentially to atomize the liquid slag and then to cool the particles rapidly so as to produce a glassy slag. Heat is recovered from the slag in the following ways. As the spray of slag particles moves outwards from the atomizer, heat is lost by radiation to the vessel and by convection to the air moving through ...

The wet granulation process operates with a high water to slag ratio of about 8:1. The advantage of the wet process is that it is accepting wide fluctuations in the mass flow and physical/chemical properties of the slag. However, the wet process faces also significant disadvantages:

Effect of Water Granulation Conditions on Density and ...

Reducing the slag temperature to 1673 K or less is effective for adjusting the unit weight to 1.40 kg/l or more. Because the slag temperature is reduced to 1673 K or less in the new granulation system, the molten slag is granulated by blowing water after the slag is charged into the slag ladle.

Hatch Ironmaking Technologies | Dry Slag Granulation ...

Dry Slag Granulation. Water granulation is the most commonly used method to handle blast furnace slag and requires a granulation and a dewatering step to process the slag. In water granulation, the energy in the slag is lost from water evaporation and cooling and is difficult or impossible to recover.
