Foundry sand production for use in the manufacturing industry
Foundry sand (also known as Casting Sand) is a high-quality silica sand that is bonded to produce moulds for ferrous (iron and steel) and nonferrous (copper, aluminium, and brass) metal castings.
The sand cast procedure is the most widely used casting method in the foundry business. Green sand is used in almost all sand cast moulds for ferrous castings. High-quality silica sand, bentonite clay (as a binder), water, and coal make up green sand (a carbonaceous mould additive to improve casting finish).
Which additives and sand grades are utilised depends on the type of metal being cast. Foundry sand manufacturing necessitates specialised screening and classification methods, as well as a thorough examination of the feed material and sand grade standards.
We manufacture the full range of equipment required on a foundry sand processing plant and the modular nature of our equipment ensures:
- Maximum process efficiency : The retention of material and water inside the circuit is maximised by paying close attention to all material transfer points, resulting in optimal product production.
- Minimal footprint : The intelligent integration of many processing processes across our modular equipment range minimises total project costs by reducing related activities to create concrete pads upon which your plant will be erected.
- Rapid Deployment : The typical stick construction / static plant technique takes substantially longer to install than our modular equipment offering. This guarantees that you are up and running as soon as feasible.
- Minimal environmental impact : By adopting our water recycling and tailings management system, you may recycle up to 95% of the water from your wet processing plant while simultaneously reducing the amount of space needed for your silica sand business.
Where is foundry sand used?
The bulk of foundry sand used for castings comes from the ferrous (iron and steel) industries.
Foundry sand is also used extensively by the car sector and its suppliers. For every tonne of iron or steel casting produced, approximately 1 tonne of foundry sand is required.
Recycling foundry sand
Recycling non-hazardous waste foundry sand may conserve energy, reduce the requirement for fresh materials, and lower prices for both manufacturers and end users. Recycled foundry sand is commonly used in building, but it can also be used for the following purposes:
- Raw materials for the production of Portland cement
- In asphalt mixes, fine aggregate can be partially replaced.
- For building mortar, sand is necessary.
To establish the potential for foundry sand recycling and its appropriate uses, an individual examination of the wasted foundry sand in terms of physical and chemical qualities is necessary.
