For almost 110 years, Hosokawa Alpine has been a world leader in providing complete installations for the
processing of mineral raw material to fine powders. Hosokawa Alpine is globally renowned for its
manufactured ball mills and mineral grinding systems.
Today, the filler industry market is larger and has grown fiercely competitive. Minerals fillers, such as
limestone, dolomite, talcum, chalk or barite - amongst others - that were considered ultrafine a few years
ago are now standard products. Thus, the industry’s requirements have changed to fine fillers with a sharp
top cut at low costs or custom-made particle size distribution. Selecting an optimum system relies on the
consideration of the different product properties e.g. the laminar structure of talc, the micro-crystalline
structure of chalk…etc, in which Hosokawa Alpine proposes a wide expertise.
Hosokawa Alpine offers its customers complete processing systems or standalone machines; various
machines are available to fulfill the customer’s needs at any stage in the processing line such as crushing,
cooling, drying, dry/wet grinding, micronisation, air classification, wet classification, storage, packing,
control unit, coating, calcinating, granulation, or compaction.
These techniques include ultrafine grinding, air classification and stearic acid treatment of mineral powders.
For each of these techniques, Hosokawa Alpine offers various sizes and types of ball mills, table roller mills,
jet mills, classifier mills, impact mills, agitated ball mills and air classifiers for the production of a wide range
of particle fineness.
By using agitated ball mills and wet classifiers, this technology permits the production of finished goods
right down to the sub micron range.
Other areas of expertise:
Precipitated Calcium Carbonate (PCC)
This product is obtained by means of a chemical precipitation process. Hosokawa Alpine offers both the
systems and the complete know-how for turnkey plants for the production of different types of PCC.
Various mineral powders such as Quartz, Feldspar, silica flour and Zircon which are the main components
of the ceramic industry are produced sing a conventional ball mill and a classifier.
This mineral is very prone to containing a certain percentage of abrasive contaminants; Hosokawa Alpine
offers using a roller mill for the grinding stage.
Hosokawa Alpine’s systems are widely spread for the processing of these materials, based on rare earth
Other key grinding and classifying applications for the minerals industry are: Silica, Zircon sand, Kaolin,
Clay, Bentonite, Aluminum Oxide, and much more.
