CSIRO has been working on a dry granulation process, integrated with heat recovery, since 2002. It involves a rotary disc that atomizes molten slag to produce liquid droplets, which are rapidly quenched to become solid granules. The hot granules are fed to a counter-current moving packed bed heat exchanger, where they are further cooled …

Slag Granulation System "RASA SYSTEM" If molten slag, a byproduct produced when steel is manufactured in a blast furnace, is rapidly cooled with jet water, granulated slag is produced. Granulated slag is recycled as raw materials for cement, etc. PARA-ECO-Recycling System.

Horizontal screw conveyors are available in a wide range of sizes, lengths, configurations and materials of construction. Inclined screw conveyor: Inclined screw conveyors typically operate from slightly above the horizontal position to 45o from the horizontal position. As the degree of incline increases, conveying efficiency is reduced and ...

The aim of the pilot-plant is a long term slag granulation test at first time with slag flows close to industrial plant sizes. In following figure a simplified flow sheet with the principle function of the STEP1 pilot plant is shown: Figure 3: Process scheme of Phase 2 STEP1 pilot-plant installation at voestalpine Stahl Linz

For example, belt conveyors for cohesive materials, screw conveyors for slightly abrasive materials or aero-mechanical conveyors for efficiency and environmental and cost savings. The suitability of a pneumatic conveyor largely depends on the specific material characteristics, environmental conditions, and the operational requirements of the plant.

Introduction of Slag Screw Conveyor. The slag screw conveyor is used in the blast furnace slag micro-powder project. It is mainly a feeding device for the slag vertical mill. The equipment has good wear resistance and strong air lock function, which can indirectly reduce the excessive energy consumption of the vertical mill due to air leakage, thereby …

A screw conveyor type slag granulation plant is a specialized system used in industries such as steel manufacturing to efficiently process and dispose of waste materials known as slag. Slag is a byproduct of the steel-making process and needs proper treatment before it can be safely disposed of.

Dry Granulation Concept. Dry slag granulation is based on molten slag atomisation using a variable speed rotating cup or dish (see Figure 1). The slag is delivered on to the centre of the cup from a slag runner via a vertical refractory lined pipe. The rotation of the cup forces the slag outwards to the cup lip where it is atomised (see Figure 2).

The iron is drawn off to be further refined into steel, and the slag is tapped off to be granulated. Granulation occurs when the molten slag (2,650° F to 2,800° F) is …

Screw conveyors are also more economical alternatives to a belt, pneumatic, or aeromechanical conveying device. Using multiple inlets and discharge points, screw conveyors efficiently distribute bulk materials to different areas. Plus, screw conveyor systems are able to contain corrosive or hazardous materials. Keeping Business …

Metallurgical slags are produced at a massive rate of over 750 Mt/year, and carry a thermal energy equivalent to 40 Mt/year of coal. The potential mineral and thermal energy values of slags are in the order of $22 b and $3–6 b per year. Such attractive figures, together with tightening legislation on disposal of slag and the carbon footprint …

Screw Conveyors are ideal for moving bulk materials like grains and powders over short distances. The system uses a rotating helical screw blade within a tube or trough which moves materials along its length. This type of conveyor is commonly used in food processing plants, agricultural facilities, and chemical industries.

4. TYPES OF SLAG After granulation of slag based on that appearance it was majorly divided into four groups. a. Sand type slag: This type of slag having size 0.5 – 1 mm, easily separates from water because of its good settling tendency. b. Fine type slag: This slag having very lower size < 0.1mm. It is always dissolved in water;

Abstract. Slag dumping and water granulation are the most commonly used slag treatment methods in the metallurgical industries. In both processes, water is present (by desire for cooling and dispersion or as a result of rain accumulation) and thus equipment and operations are designed to minimize and mitigate the risk of steam …

The chart above illustrates the distance/length requirement for the level of incline on an inclined conveyor. In addition to a lower profile, the "L" and "S" configurations of the steep incline conveyor allow it to replace multiple pieces of handling equipment; one S-type steep incline conveyor can replace two belt conveyors and a bucket elevator, …
