Ultraplex UPZ

Versatile size-reduction system:

  • Exchangeable grinding elements: beater disc, pin discs, swing beaters and plate beaters, sieves and grinding tracks
  • End-product fineness in the range 50 µm to approx. 5 mm in accordance with the grinding equipment installed
  • Size reduction of soft materials up to 3.5 on the Mohs' scale
  • Generously dimensioned mill door for easy cleaning and exchange of grinding elements

Principle of operation

Alpine Ultraplex UPZ fine impact mills offer versatility in use combined with simplicity in operation. Because of the wide variety of feed materials, where every comminution task demands its own tailor-made solution, the UPZ mills can be equipped with a variety of easily interchangeable milling elements. Tough-fibrous roots and spices, for example, require completely different milling elements to granulated sugar in order to optimally fulfil the individual requirements, both in technical and economic terms.

UPZ mills can be equipped as a pin mill without sieve with one rotating and one stationary pin disc. Or as a beater mill with beater disc, swing or plate beater unit for operation with grinding tracks or sieves.

The overall result is a host of practice-oriented and perfectly coordinated equipment combinations. In short, the UPZ mill can be tailored to match every customer's individual requirements.


UPZ fine impact mills can be equipped with a host of different milling elements, thus fulfilling a great variety of demands on the end product, for example:

  • High fineness with sharp top cut
  • Production of end products that are low in fines with good flow properties
  • Production of powders with a high bulk density
  • Production of powders with a high mass fraction within a defined particle size range

The interchangeability of the milling elements is becoming increasingly important for the user.

The UPZ offers the right milling element for every job:

UPZ beater disc unit

  • Beater cams made of wearproof cast steel
