· Granulation And Heat Recovery From Metallurgical Slags Dec 09, 2019 Metallurgical slags are produced at a massive rate of over 750 Mtyear, and carry a thermal energy equivalent to 40 Mtyear of coal. The potential mineral and thermal energy values of slags are in the order of 22 b and 36 b per year.

· Roller compaction (also referred to as ribbon blending) is a relatively simple, more efficient and inexpensive form of dry granulation. It is a process where formulation ingredients are continuously passed between two counterrotating rollers where it is densified and consolidated into a sheet of solid mass.
The flow chart is shown in Figure 1. The molten slag is transported in a slag pot from the steelmaking workshop to the slag treatment yard. A turnover unit pours the slag into a hopper in which there are several rotors to granulate the molten slag. This unit is the primary granulation. It acts as a buffering and first heat exchange system, in ...
The granulated slag samples were collected from the water granulation system at No. 6 blast furnace at East Japan Works (Chiba District), JFE Steel Corporation. Figure 1 shows the outline of this water granulation system. 12) The slag was recovered with sampling equipment set up between the conveyors at the outlet side of the dehydrator.
ten slag, rotating speed and surface roughness of disc is simulated. The influences of various factors on granulation process are analyzed and optimum parameters are obtained. The results show that the granu lation can be greatly improved by increasing the rotating speed of the disc and by reducing the molten slag viscosity properly.
Figure 1 shows a schematic diagram of a device. The basis of the device is a container 2 which is provided with an actuator of rotation about the axis of the pivot bearing 4. Hinge support 4 provides the possibility of rotation of the container relative .
The granulated BF slag were almost amorphous solids as amorphous solids sample. The component of the slag were w(CaO) %, w (SiO2) %, w (Al2O3) %, w (MgO) %, w(FeO) %, w(S) % and R＝ Methods (1) The 10g BF slag by water quenched with amorphous solids were put into the crucible as the thin layer.
Pyrometallurgical slag cleaning usually consists of heating the slag, reduction of oxides and settling of matte/metal droplets. Heating the slag decreases viscosity and accelerates reactions. Reduction of magnetite liberates inclusions and facilitates co reduction of dissolved metal oxides.

of the granulation phenomena during the experiment. Figure 1 shows a schematic diagram of the experimental apparatus. The molten slag was placed in an induction furnace. After melting, the temperature of the molten slag was maintained at 1700K. The molten slag was poured onto the spinning disk that was rotated by a motor at the base. The

matte is transported to and processed further at the Anglo Platinum Converting Process (ACP) within the Waterval Smelter Complex in Rustenburg. Furnace slag is granulated, and processed through a slag mill, or transported to a slag dump. INTRODUCTION Mortimer Smelter went into operation in 1973, with the commissioning of #1

Slags are essential in high temperature metallurgical processing to purify molten metal at competitive prices. Large volumes are produced annually, leading to important economical and ...
matte granulation process and the differences between the original and proposed upgraded process are discussed. The design, instrumentation and control systems work completed for the addition of new equipment and instrumentation for the matte granulation system upgrade of the Kalgoorlie Nickel Smelter (KNS) Expansion (KSE) project is addressed. The future work . ii .

In this process, molten BF slag flow rate is controlled by a slide gate to keep a constant slag level in the slag tundish so that the molten slag can be stably and continuously poured onto the rotating cup, and then partially granulated and dropped to the rolling crusher. There are two lines rollers in the process system.

The particle size of GPI is in the range of 5 mm to 25 mm. GPI has a high angle of repose, which allows for effective transport and storage. Process The granulation process has four principal steps: control of the flow of hot metal to the granulator granulation by formation of liquid iron droplets, followed by rapid quenching in water
The slag is then either run into large pits at the side of the furnace for aircooling into an aggregate product, or through a forced quenching system such as a slag pelletiser or a slag granulator. Click here to view Figure 1 Figure 1. Iron ore blending operation 4 LPS 111/2001 ISSN X
