At a share of approx. 12 %, quartz
ranks second behind feldspar as
the most common mineral
of the lithosphere, either in the form of solid rock or
eroded sand.
After being processed to quartz sand < 600 µm,
the quartz is used
 |
in the manufacture of glass |
|
for special paints (road building) |
|
in foundries as moulding sand |
|
in adhesives for the ceramics
industry |
|
in sand blasting equipment |
|
for sanding sports stadiums,
etc. |

Alpine's Super Orion ball mill |
Quartz that has been comminuted and
classified even finer in the < 80 µm
range with a steep particle size distribution is found
in ceramic base compounds, and at a fineness of < 20 µm
in glazes.
The combination of Alpine's Super Orion ball mill with
an Alpine ultrafine classifier has proved itself as the
ideal solution for such superfine processing jobs. |
The system schematic shows an Alpine quartz powder system with
which three different end products for different applications
can be produced simultaneously.Thanks to the installation of
two ultrafine classifiers from the Turboplex and Stratoplex
product lines, the following end products are generated simultaneously:
99.8 % < 80 µm with 50 % = 15 -18 µm for ceramic
base compounds
99.8 % < 20 µm with 50 % < 3 - 4 µm for glazes.
As an option, the coarse material from the first classifying
stage – i.e. 97 % < 150 µm or 97 %
< 100 µm – can be filtered out of the
process for use as the starting material for sodium silicate
and many other products.
The ball mill is lined with silex to ensure non-ferrous production.
If, as an alternative, aluminium oxide were to be used as the
wear protective lining, the subsequent increase to the machine
availability would constitute an added advantage. Flintstones
or aluminium oxide of a fixed grading is used for the grinding
media. Product-contact components in the classifiers, filter
bins, etc. are made of aluminium oxide or are coated or lined
with PUR. The entire system is controlled from a central control
cabinet.
