REM Foundry is built on a 10.000 sqm surface and a further 7.000 sqm added in 2010. The Foundry was designed to manufacture castings made to customer specifications. Here were casted parts ranging from 1 tone up to 50+ tones, for industries like: wind mills, heavy machine tools, mining, energetic etc.
Foundries are one of the largest contributors to the manufacturing recycling movement, melting and recasting millions of tons of scrap metal every year to create new durable goods. Moreover, many foundries use sand in their molding process. These foundries often use, recondition, and reuse sand, which is another form of recycling.
Used foundry sand A review and study of foundry waste sand quality and composition was performed in Finland. Data were collected from literature and from own experiments [169, Orkas, 2001], In several studies, chemical analyses on used foundry sands from various sources were performed.
The attrition mill reduces sand lumps to grain size and removes tramp metal. Carrier's heavy duty attrition mills are designed for reliable use and low maintenance requirements, and utilize a unique pneumatic gate that discharges metallics without shutting down.

Attrition Mills. An Attrition Mill is used for reducing "no bake" bottom sand lumps to "grain size" of minus 20 mesh or green sand to small particles. Sand is dumped into the rear hopper section. The lumps rub on one another and produce "fine" grains which can convey up a steep incline.
What is foundry sand? Most metalcasting sand (FS) is high quality silica sand with uniform physical characteristics. It is a byproduct of the ferrous and nonferrous metal casting industry, where sand has been used for centuries as a molding material because of its unique engineering properties.
Used foundry sand (UFS) (Fig. 4.1) is a discarded material coming from ferrous (iron and steel) and nonferrous (copper, aluminium, and brass) metal-casting industry to create molds and cores. About 1 ton of foundry sand for each ton of iron or steel casting produced is used (Siddique and Noumowec, 2008).
Sand casting, also known as sand molded casting, is a metal casting process characterized by using sand as the mold material. The term "sand casting" can also refer to an object produced via the sand casting process. Sand castings are produced in specialized factories called foundries.Over 60% of all metal castings are produced via sand casting process.
Green sand is a compound mixture used for casting of metals in foundry applications as a mould. It is 'green' not by colour, but takes the moniker due to the fact that it is not 'set' when the metal is poured into it, rather it is still in the 'green' or uncured state.

In metallurgy, a ladle is a vessel used to transport and pour out molten metals. Ladles are often used in foundries and range in size from small hand carried vessels that resemble a kitchen ladle and hold 20 kilograms (44 lb) to large steelmill ladles that hold up to 300 tonnes (330 tons). Many non-ferrous foundries also use ceramic crucibles for transporting and pouring molten metal and will ...

07-05-2020· Foundry sand is clean, uniformly sized, high quality silica sand, used in foundry casting processes. The sand is bonded to form molds or patterns used for ferrous (iron and steel) and non-ferrous (copper, aluminum, brass) metal castings. Shake-out sand from completed metal casting are often reclaimed back into the foundry sand process.
