Application of Foundry Waste Sand In Manufacture of Concrete
Metal foundries use large amounts of sand as part of the metal casting process. Foundries successfully recycle and reuse the sand many times in casting process. When the sand can no longer be reused in the foundry, it is removed from the foundry and is termed as "foundry waste sand." Like many waste products, foundry sand has beneficial …
The Aggregate Manufacturing Process | General Kinematics
Aggregate Processing. During processing, aggregates are distilled down to a level of their most common use. Some aggregates may be crushed to a powder while others may be screened to various diameter chunks. The proper processing of aggregates is important in maintaining their desirable qualities. For instance, between 60 and 75 …
