The applications of silica as an addivitve are many and varied, for example:

a) For heavy-duty rubber articles and adhesives.
b) As a moisture binder to make and keep products manufactured by the foodstuffs, pharmaceutical and chemical industries free-flowing, or to alter the viscosity of products (thixotropy).
c) As a cleaning additive in toothpaste.
d) In paints to prevent dripping and trickling and also as a delustering agent, etc.
e) As an anti-foaming agent (e.g. in emulsion paints)

To manufacture the customary fineness values, e.g. d50 = 10 µm or d50 = 5 µm (corresponds to 97% < 15 µm), we use the Alpine Fluidised Bed Opposed Jet Mill AFG. Higher fineness values are possible assuming suitable machine settings. To achieve maximum throughput rates with this product, we operate the machine with hot grinding air (approx. 150°C).
