In plants where silica flour is to be produced, drying is often necessary. Drying is done in rotary, oil or gas fired dryers. Dry grinding to minus 100 or minus 200 mesh is done in Mills with silica or ceramic lining and using flint pebbles or high density ceramic or porcelain balls. This avoids any iron contamination from the grinding media.
2. Food contact and kitchen items. Since silicone rubber is highly stable against chemical degradation, it is a suitable material for products that come into contact with food. The material is so safe that it is notably used for the nipples of baby bottles – a true testament to its being chemically inert and non-toxic.
Micro-fluidics chips, optical elements and Micro-TAS are widely used components made from fused silica which have micro structures with fine surface quality. In recent years, micro-milling has been widely applied to manufacturing these components due to its high machining efficiency, accurate removal amount and flexible machining ability.

Silica Sand. Silica Sand a specialized sand, that has many different uses. Silica Sand is a washed and dried material. It comes in various sizes ranging from a very fine material to an extremely course variety. Finer sizes of the material can be toxic to breath, and caution must be used during the installation of finer grades of Silica Sand.
The mill used silica, crushed and screened, as the grinding medium. The new mill was commissioned in late 2003 and met Anglo Platinum's performance expectations, including almost perfect scale-up. It had lower operating costs than the smaller M3000 unit installed in a similar duty at Lonmin's operation.
