Properties of mixtures of Portland cements and "waste steel foundry dust (WSFD)" from Czech steel works were examined. It was found that WSFDs are formed by microporous clusters of spherical particles of iron oxides, ranging in size from 10 to 100 nm.The content of ZnO in WSFD affects markedly the hydration of cement+WSFD …

Clay sand casting generates a large amount of foundry dust (FD), and the presence of coal powder in the FD makes it difficult to recycle and utilize. The landfill of the FD creates a serious environmental pollution and wastes a valuable resource. To improve the above situation, the FD was analyzed and characterized by X-ray fluorescence …

In a recent report, Imerys High Temperature Solutions, Foundry Div. director of Sales & Business Development Tim McMillin estimated the recovery value of those materials at $45 million. "'The …

Watts Water Technology installed a Camfil Gold Series high efficiency dust collector on a core knockout system at their foundry to handle the large volume of sand from metal …

The most large-scale foundry waste is burnt molding earth, which is formed at the stage of knocking out castings from foundry molds. The properties of burnt molding earth (humidity, loss on ignition, elemental, phase, and grain composition) were studied and the possibility of its regeneration was confirmed. It is shown that during mechanical …

The spent foundry sand is either recycled in non-foundry applications or landfilled. In 2007, the American Foundry Society estimated (PDF) (5 pp, 1.94 , …

With a growing awareness of environmental protection, the dust pollution caused by automobile foundry work has become a serious and urgent problem. This study aimed to explore contamination levels and health effects of automobile foundry dust. A total of 276 dust samples from six types of work in an automobile foundry factory were …

The composting method can be considered as an effective cleaning method. The degradation of the harmful substances during the composting tests of organic dust compost and organic waste sand compost and the cleaning efficiency rates. In summer 2020 composting test was carried out with inorganic binder system foundry waste sand.

Waste foundry sand (WFS) is the by-product of the foundry industry, which is produced about 0.6 tons per 1 ton of foundry industry production. While it cannot be recycled or reused, it will be disposed of in landfills. Today, with increasing attention to environmental issues, the reuse and recycle of materials because of limited resources …

Non-metallic foundry waste is generally composed of spent green sand, core sand, and dust collect- ed in the ventilation bag-house systems of the foundry facility. Currently, practices exist for ...

Sand reclamation involves physical, chemical, or thermal treatment of sand for reuse in molding and coremaking. There are two major types of systems, mechanical and thermal. A mechanical system physically breaks down lumps of spent casting sand, into clean sand. A thermal reclamation system takes sand that has been broken down to …

With respect to recycling options, we determined that the shakeout stream can be reused in both concrete mix and cement manufacturing. However, special precautions should be taken regarding the clay content of sands originating from greensand foundries. Due to its finer grain size, dust streams can only be recycled in cement …

Making one aluminum can from scratch uses as much energy as making 20 from recycled aluminum [11]. The turnaround time for a recycled aluminum can to be turned into a new aluminum can is just 60 days [12]. The typical aluminum can contains 68 percent recycled aluminum, and this reduces the total energy needed to produce new cans by 50 …

This fine, powdered coal has been used to improve the surface finish of iron and copper castings since the 1870s. Used in greensand and dry sand moulding, coal dust protects the mould surface against the action ...

A typical EAF dust recycling process looks like this: The kiln feed material, comprised of zinc 'waste,' fluxes, and reductant (coke), is typically pelletized before addition to the kiln. First, however, EAF dust is pre-conditioned via blending with water. This helps to reduce dust during processing and also prepares the material for pellet ...

All of that means foundries need to take steps to control the amount of dust in the air and contain the many ignition sources present in any foundry. The truth is, as an industry, we do an excellent job controlling combustible dust. Otherwise, you would be reading about explosions on a weekly basis, and that doesn't happen.

The massive amount of coal dust in foundry dust is a potential impediment to the recycling of foundry dust, and the efficient separation of coal dust is crucial to solving the above problems. In this paper, the flotation separation of coal dust from foundry dust enhanced by pre-soaking assisted mechanical stirring was reported. The influence of ...

Clay sand casting generates a large amount of foundry dust (FD), and the presence of coal powder in the FD makes it difficult to recycle and utilize. The landfill of the FD creates a serious environmental pollution and wastes a valuable resource. To improve the above situation, the FD was analyzed a …

22.02.2021. Did you know that sand is the second most-consumed natural resource in the world after water? Finn Recycling developed a technology that makes it possible to purify, regenerate and recycle industrial waste …

The spent foundry sand, that is, the sand that is removed, is either recycled in a non-foundry application or landfilled. Estimates are that less than 15 percent of the 6-10 million tons of spent foundry sands generated annually is recycled. The Agency believes a greater percentage of spent foundry sand can be safely and economically recycled.

Industrial dust and fume collectors are designed to remove particulates from the air and recycle the clean air back into the factor. If you are operating a foundry, then this matters because keeping your factory air clean of fumes and dust is important. With cleaner air in your foundry, your staff is less likely to suffer health problems.
