1.3 Brief description of the device
1.3.1 Fields of application
The cross beater mill serves primarily for preliminary and fine comminu-
tion 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,
potash, tablets, slag, minerals, ash, stone and earth (bauxite, limestone,
dried clay, etc.), synthetic resins, pyrite, cement clinker, coke, ores, re-
fractory materials.
1.3.2 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 the cross beater mill and the collecting vessel.
This ensures a gentle grinding process.

2 Operating safety
2.1 General safety instructions
•Study the operating instructions carefully.
•All operators must be familiar with the contents of the operat-
ing instructions.
For this purpose, always keep the operating instructions within
easy reach.
•Do not remove the instruction labels.
•Do not disable safety devices.
•Independent conversions of the device negate the conformity
with European directives declared by Fritsch and void the war-
ranty.
•The cross beater mill is intended exclusively for use as speci-
fied in the section 1.3.1 .
Any other use is considered improper; the manufacturer ac-
cepts no liability for damages resulting from improper use.
•In addition to the operating instructions, observe and instruct
adherence to all generally applicable statutory and otherwise
binding regulations on accident prevention and environmental
protection.
•If a noise level of 85 dB(A) is reached or exceeded, hearing
protection should also be worn to prevent hearing damage.
•Use original accessories and spare parts only. Failure to ad-
here to this may jeopardize the protection of the machine.
•Do not continue using damaged accessories.
•The occupational exposure limits of the valid safety instruc-
tions must be observed and if necessary, ventilation should be
provided or the machine should be operated under a hood.
•During comminution of oxidisable substances (e.g. metals or
coal), there exists a danger of self-ignition (dust explosion) if
the portion of fine material exceeds a specific percentage.
•The cross beater mill is not designed with explosion protection
and is not suitable for grinding of explosive materials.
•These operating instructions do not contain any repair instruc-
tions. Repairs may only be performed by Fritsch GmbH or
authorised service technicians.
2.2 Operators
•The cross beater mill may only be operated by authorised
persons and maintained and repaired by trained experts.
•People who are under the influence of health impairments,
medications, drugs, alcohol or excess fatigue may not oper-
ate the cross beater mill.

2.3 Protective devices
•Protective devices should be used for the intended purpose
and must not be made unserviceable or removed.
•All protective devices must be regularly inspected for com-
pleteness and proper function. See sections 6Maintenance
and 7Required inspections.
2.4 Danger points
Process Action Dangers
Safety Damages and injuries resulting from failure to
follow the safety instructions All forms of claims for damages are excluded
Packaging Please keep the packaging for the duration of
the warranty period A complaint and return in insufficient packag- ing can put your warranty claims at risk
Transport Do not jolt, shake or throw the “pulverisette 16”
during transport Electronic and mechanical components can be damaged
Temperature fluctuations In event of temperature fluctuations, protect
the “pulverisette 16” from condensation Electronic components can be damaged
Scope of delivery In event of incomplete delivery and/or transport
damages, you must immediately notify the
shipper and Fritsch GmbH (within 24h).
Complaints registered later than this can no
longer be accepted under some circum-
stances.
Ambient temperature Falling below 5 °C
Exceeding 40 °C Electronic and mechanical components can be damaged
Performance data changes to an unknown
extent.
Humidity Exceeding of 80 % at
temperatures up to 31 °C Electronic and mechanical components can be damaged
Performance data changes to an unknown
extent.
Electrical connection Power network does not match the values on
the type plate Electronic components can be damaged
Before starting up the device for the first time,
the rotation direction must be checked; see the
directional arrow on the motor.
With an incorrect rotation direction, the grind-
ing performance is insufficient and mechani-
cal components may be damaged.
Opening and closing of the mill
housing Only close the door when the contact surfaces
are absolutely free of grinding material and
other contaminants.
Mechanical components and the seal can be
damaged.
Do not open “pulverisette 16” while the motor
is running. In the grinding of toxic or otherwise harmful substances, there is a risk of inhalation of
dusts that are harmful to health.
Do not open the “pulverisette 16” and release
the motor brake at the same time. Risk of injury from the unbraked cross
beater.
Adding material for grinding Add material for grinding slowly and continu-
ously into the filling funnel. Adding too large an amount can bring the “pulverisette 16” to a stop and could damage
mechanical components.
During grinding, dust-sized grinding material
can escape from the filling funnel. Use a vac-
uum hood when working with toxic or otherwise
harmful materials.
Danger of inhalation of harmful dusts.
Some grinding materials form explosive mix-
tures in air.
Check the material properties of your grinding
material.
Risk of explosion.
Cleaning Pull the power plug before every cleaning. Life-threatening risk of electric shock
Do not clean with flowing water Life-threatening risk of electric shock
