Granulating Slag Crushing Plant

Crushing Plant Design and Layout Considerations Ken Boyd, Manager, Material Handling, AMEC Mining & Metals, Vancouver, BC ABSTRACT In mining operations, the layout of crushing plants and ancillary equipment and structures is a crucial factor in meeting production requirements while keeping capital and operational costs to a minimum.

mercial Slag Atomization Plants, two of which have been for the last decade successfully ... This air-driven slag granulation technology has been applied to the steel and non-ferrous sectors at full-scale, granulating up to 200,000 tonnes per year of slag per unit. Recently, we have demonstrated further scale-up of the technology to

After cooling to 93°C (200°F) or lower, the slag is transported to a plant for crushing and screening to a size appropriate for concrete use (Dobrowolski, 1998). Air-cooled blast furnace …

2.Crushing Process: The compost lump materials should be ground before the granulating process. But we can leave out crushing process when the compost material is fine enough. Vertical chain crusher and double-shaft horizontal crusher, two types of crushing machine can be used to crush lump compost fertilizer raw materials.

The US SLAG (VSI CRUSHER) was developed for crushing and particle shaping of slag from steelworks and waste incineration plants. The reliability of the US SLAG (VSI CRUSHER) is highly regarded, as it was developed from the basic design of the well-known Husler crusher, of which more than 1000 units have been supplied by Kemco.

A conventional quarry process may consist of at least three crushing stages, a minimum installation beginning with a primary (jaw) crusher to reduce all the material to less than 150-200mm. A secondary (cone) crusher is used to crush this down to around 40mm, and finally a tertiary (VSI) crusher can shape and grade the final product ready for ...

Table 1 lists the key parameters of slag waste heat recovery process, clearly, discharged slag particle temperature by mechanical crushing methods is high, but heat recovery rate is less than 65% and slag particle size is larger than 3 mm. Definitely, they are neglected right now for poor performance and economic efficiency.

1. Introduction. Molten blast furnace slag (BFS) is the main by-product of iron making process with the 1450–1550 °C discharge temperature [1], which contains large amounts of physical sensible heat and belongs to high-quality waste heat resource [2].Each ton of molten slag contains 1260–1880 kJ thermal energy which is equivalent to 60 kg standard coal [3], [4].

High-temperature waste heat from the iron and steel industry, as shown in Fig. 1, are mainly stored in products, molten slag and waste gas [2].Molten slag, as a kind of by-product during the steelmaking process, is exhausted in extremely high temperature and thus, it carries a great deal of high-grade heat accounting for 10% of waste energy in steel industry and 35% of …

At present, the water-quenching technique is widely adopted to treat BF slag in most iron and steel plants worldwide, where the molten BF slag is rapidly cooled by cool water …

After cooling to 93°C (200°F) or lower, the slag is transported to a plant for crushing and screening to a size appropriate for concrete use (Dobrowolski, 1998). Air-cooled blast furnace slag has been extensively used as a construction aggregate. 5.3.2 Granulating

Molten blast furnace (BF) slag is one of the main by-products in the iron-making process, and has a yield of 300 kg/t-pig iron [1].The heat contained in molten BF slag (1500 °C) reaches up to 1600 MJ/t.Globally, the production of pig iron was nearly 1153 million t in 2015 [2], and about 345.6 million t of BF slag were produced.The total energy carried by molten BF slag …

An object of the present invention is to provide a method for treating exhaust gas generated when crushing slag discharged into a nonferrous metal smelting furnace. It is a method of treating the exhaust gas containing a metal fume mainly by the water vapor generated when the slag discharged from a nonferrous metal smelting furnace is crushed, and including the process of …

The closest technical solution to the invention is a plant comprising a device for crushing a melt with water, a settling bunker, located in the last elevator with per-20 fortified buckets and conveyor 23. ...

Slags are byproducts of the metallurgical industry. It is of importance to recycle materials and recover heat from metallurgical slags to reduce the energy consumption and environmental impact of steel industry. China is the largest iron- and steelmaking slag producer in the world, and intensive efforts have been made during last decades for slag valorisation, …

Following different test series, where the slag quality and suitability for cement production was proven, Paul Wurth built a full scale dry slag granulation pilot plant at Rogesa's blast furnace No 4.

These products include granulated blast furnace slag, by-product of blast furnace production, which is produced by granulating slag in water. This also includes blast furnace slag crushed stone. It is produced by crushing at the Crushing and Screening Plant. Crystalline ammonium sulfate, granulated coal tar pitch and so on.

Primarily designed for the purpose of grinding, this plant is capable of processing a wide range of materials, including limestone, raw meal, slag, nickel slag, manganese slag, cement, ground granulated blast-furnace slag (GGBS) …

Molten slags of blast furnace is a second resources with great value of 1600~1 800 MJ sensible heat per ton. At present, water-quenching process plays a leading role in recovering waste heat of ...

The Crusher Department is concerned with equipment for production of suitable A conventional quarry process may consist of at least three crushing stages, PLANT FACILITIES Optimum for crushing/granulating slag from fusion furnace.

Slag is by-product from steel plant, which is obtained from blast furnace, during the separation of iron from iron ore. The process of granulating of the slag involves, cooling of molten slag through high-pressure water jets. This rapidly quenches the slag and forms granular particles. The resulting granular material comprises around 95%,

Experimental results on the dry slag granulator pilot plant have demonstrated that the process can effectively produce glassy slag granules from molten iron blast furnace slag, and...

The gas quenching granulation technique was first developed by Mitsu-bishi Heavy Industries and Nippon Kokan KK (now JFE) [12]. In the early works, airflow velocity was less than 100 m·s −1 [13], which brought about two problems: one was that impact kinetic energy was not enough, the obtained slag particle diameter was larger (the average diameter is about 2–4 …

Currently, molten slag water quenching process is adopted for slag resourceful disposal, neglecting waste heat recycling and environmental burdens such as sulfur dioxide or hydrogen sulfide formation [4].By contrast, dry granulation is an environment-friendly process reconciling molten slag waste heat recovery and slag resourceful disposal, in which the …
