Loading the Mill: The ball mill is loaded with the material to be ground and the grinding media (balls). The material can be fed into the mill either wet or dry. Rotating the Mill: Once loaded, the cylindrical shell starts rotating around its horizontal axis. Various mechanisms, such as gears, belts, or direct drives, can facilitate this rotation.
the dust produced by hand-fettling operations [5] [9]. Safe-operating procedures, if followed, can decrease the risk of these worker injuries. An evaluation of foundry accidents has shown that one of the major contributing factors in foundry injuries was lack of, or violation of, safe-operating procedures[10]

Fettling in the foundry industry refers to the process of removing excess material, such as flash, gates, risers, and burrs, from castings to achieve the desired final shape, size, and surface finish.
This cleaning up is known as fettling the casting. Since castings may be of quite complicated shapes, fettling is a time consuming operation. Robots in the foundry Because it is such a noxious environment, the foundry seems an obvious place for robots to find useful applications. So far the penetration of robots has been slow.
The FILL MACHINE ENGINEERING Grind Performer F automated work cell for high-tech fettling and grinding is operated by an industrial robot to simplify finishing of iron castings. Thanks to an automated tool-replacement system, it can carry out the various operations fully automatically, whether deburring small iron castings or massive ones.
The majority of foundries specialize in a particular metal and have furnaces dedicated to these metals. For example, an iron foundry (for cast iron) may use a cupola, induction furnace, or EAF, while a steel foundry will use an EAF or induction furnace. Bronze or brass foundries use crucible furnaces or induction furnaces.
Many serious foundry accidents occur during furnace charging, when foundry workers come in close proximity to the molten bath. Splashes caused by dropping large pieces of scrap and water/molten metal explosions caused by wet or damp scrap can be reduced through the use of drying and preheating systems and remotely controlled …

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.
