As per foundry practice, the LOI of prepared sand should be in the range of 1%–3.5% and 3%–6% for core and mold production respectively. As expected, the LOI of mechanically reclaimed sand is nearly 3.6%, which is higher as compared to the thermally reclaimed sand.
In modern foundry practice, sand is typically recycled and reused through many production cycles. Industry estimates are that approximately 100 million tons of sand are used in production annually. Of that, four (4) to seven (7) million tons are discarded annually and are available to be recycled into other products and industries.

The reason for long lead times is that most Finnish foundries are engaged in series production with standard molding methods. Another important factor is a shortage of skilled foundry engineers, such that in many foundries the operators are so occupied with series production that they do not have the time to work on small- to medium-sized orders.

Introduction. The foundry industries are greatly involved in the worldwide automotive, agro-industrial, and military markets [1]. Moreover, the high demand for products derived from the casting of metallic materials results in a large volume of …
MinSand is a synthetic sand produced from Alumina. Because of its almost perfectly spherical particle shape, MinSand is widely used in the foundry industry as a mould and core sand. In core production, binder savings can be achieved when compared to other sands. This is attained without any loss in the core's strength.

Sand casting is a process that utilizes non-reusable sand molds to form metal castings. On one hand, casting is a deceptively simple manufacturing process: anyone who has formed castles at the beach knows sand can be used to make detailed shapes. However in a foundry, dealing with the heat of molten metal, many factors must be considered for ...

The Green Sand-Casting foundry is equipment with automated sand delivery and mold handing systems. Because efficient production time (costs), is a vital part of a successful business, Plymouth's equipment consistently regulates mold hardness to reduce core-flashing and parting lines, thus reducing secondary finishing time (costs).
Chrome Foundry Sand in the steel industry. In steel production, Chromite Sand is used as well filler for protection of the sliding gate in large steel holding ladles. Chrome Foundry Sand in the glass industry. When ground to a fine flour, Chromite Sand is used for the production of green glass beverage containers.
The metal casting industry generates spent foundry sands. Foundries purchase new, sand to make casting molds, and the sand is reused numerous times within the foundry. This reuse eventually renders the sand unsuitable for use in casting molds, and a portion of the sand is continuously removed and replaced with sand.
Other foundry production (Cores production Foundry B) produces two types of sand cores using the Hot Box and Cold Box methods which are used in the processes for producing aluminium castings and consumes a total of 1754.411 kg/t of input materials (Table 2), creating white waste sand and black waste sand. Black waste sand is a sand category ...
Of the 6 to 10 million tons of spent foundry sand generated annually, less than 15 percent is recycled. (6) Additional information on the production and use of spent foundry sand in construction materials applications can be obtained from: American Foundrymen's Society, Inc. 505 State Street.
Cleaner Production Manual for the Queensland Foundry Industry November 1999 Page 7 systems are used. Green (wet) sand systems, the most common sand system, use bentonite clay as the binder, which typically makes up between 4% and10% of the sand mixture. Water, which makes up around 2–4% of the sand mixture, activates the binder.

Foundries successfully recycle and reuse the sand many times in a foundry. When the sand can no longer be reused in the foundry, it is removed from the foundry and is termed "foundry sand." Foundry sand production is nearly 6 to 10 million tons annually. Like many waste products, foundry sand has beneficial applications to other industries.
As foundry sand is an integral part of the casting process, using sand that is too hot or too cold leads to reduced casting quality, with lasting negative affects along the entire production line. When the molten metal is poured into a mold with green sand that is too hot, it can result in higher scrap rates as well as more consumption of ...
