1 General/Introduction

1.1 Notes about the operating instructions

• Study the operating instructions carefully.

• The cross beater mill “pulverisette 16” is referred to below as the cross

beater mill.

• All operators must be familiar with the contents of the operating instruc­tions.

• Please follow the notes for your safety.

• The cross beater mill was designed from a perspective of user safety;

however, some residual dangers could not be eliminated. Follow the ad­vice in these instructions to avoid risks to users.

• The symbols in the right hand margin highlight the risks described in the
text.

• Symbols on the device warn about possible dangers or refer to these op­erating instructions. The symbol in the right page margin (triangle with an
exclamation point) indicates general dangers and refers to the operating
instructions.

• These operating instructions do not constitute a complete technical de­scription. They describe only the details required for safe operation and
maintenance for usage under normal conditions.

• The copyright to these technical documents is the property of Fritsch
GmbH, Laborgerätebau.

• These operating instructions are not to be reprinted or copied without the
express approval of Fritsch GmbH, Laborgerätebau.

1.4 Brief description of the device

1.4.1 Fields of application

The cross beater mill serves primarily for preliminary and fine comminution of
medium-hard, brittle materials up to Mohs hardness of 6. Thanks to a large
selection of accessories, the cross beater mill is a device with wide-ranging
fields of application primarily in the areas of chemicals and ceramics, in min­ing and metallurgy as well as in the preparation of soil samples, etc. in the
laboratory and in industry.

The achievable final fineness depends on the hole width of the bottom sieve
and the grinding properties of the material to be ground. Under good condi­tions, fineness levels < 100 µm can be achieved.

Typical applications for soft materials:
Needles, leaves, grain, resins, cellulose, chemicals, dried fruits, peat, seeds,

dried plants
Typical applications for medium-hard materials:
Animal feed, salts, pellets, coal, porcelain clay, spices, gypsum, drugs, pot-

ash, tablets, slag, minerals, ash, stone and earth (bauxite, limestone, dried
clay, etc.), synthetic resins, pyrite, cement clinker, coke, ores, refractory ma­terials.

1.4.2 Method of operation

The comminution in the cross beater mill takes place through impact­ing, colliding and shearing effects. After introduction into the filling
funnel, the material enters the grinding chamber, where the com­minution process occurs between the cross beater, grinding insert
and bottom sieve.

As soon as the material has reached the corresponding final fine­ness, it passes through the bottom sieve into the collecting vessel.

A back draft of the air flow generated by the rotating cross beater is
prevented and an acceleration of the material throughput is partially
achieved with the use of a textile filter hose between

mill

and the collecting vessel.

This ensures a gentle grinding process.
