2 Safety Instructions and Proper Use

2.1 Requirements on the Operator

This operating manual is intended for persons who are assigned the operation and
supervision of Fritsch Jaw Crusher.
Persons under the influence of health impairments, medications, drugs, alcohol or
excessive fatigue may not operate the instrument.

The instrument may only be operated by authorised persons and may only be
maintained and repaired by trained experts. All commissioning, maintenance and
repair work may only be performed by qualified personnel!
The instructions of this manual must be heeded in order to avoid danger to the
user.

This operating manual is not a complete technical description. Only the details
required for operation and preserving the operability of the instrument are described
here.

Fritsch created and checked this operating manual with great care. However, no
guarantee can be provided with regard to completeness and the absence of errors.
Subject to technical changes.

2.2 Proper use

The „pulverisette 1“ is a laboratory jaw crusher for the pre-crushing of hard-brittle
substances especially for the following fields of application: mining and metallurgy,
geology and mineralogy, chemistry, glass and ceramics, earths and stones.
The initial feed size is of a maximum

• of 65 mm for the type P1/I

• of 100 mm for the type P1/II

The obtainable final size - depending on the gap setting - is from about 15 mm to 2
mm.

The jaw crusher described here is a tool for use in industrial environments.
The instrument may only be used for this purpose.

2.2.1 Method of Operation

The crushing of the materials is being done within a crushing chamber consisting of
two lateral support walls (13), one settable fixed crushing plate (18) and one
movable crushing plate (22). The movable crusher jaw (21) is put into an eccentric
movement by means of a fly-wheel and a sturdy cam.

Due to its special motion sequence, the materials to be crushed are drawn into the
crushing chamber and the blockage of crushed pieces is prevented.
The material drops from the crushing chamber through the adjustable discharge
gap into the collecting vessel (12).

2.5 Machine safety instructions

We recommend that a safety logbook should be kept in which all work (service,
repairs etc.) carried out on the machine should be entered.

Use only original accessories and original spare parts. The safety of the machine is
impaired if this instruction is not followed.
Operating personnel must always operate the machine with safety in mind.

Do not run the laboratory jaw crusher unsupervised.

DANGER

DANGER

DANGER

Danger of explosion!

The machine is not explosion protected and is not
designed to grind explosive materials.

Danger of explosion!

When grinding oxidable materials (e.g. metals or
coal), there is a risk of instantaneous combustion
(dust explosion) if the material exceeds a certain
fineness. The fine material can be absorbed through
a filter in the back of the machine and could ignite on
electric components. It is therefore necessary to take
special safety precautions when grinding such
material and the work must be supervised by a
specialised

Do not deactivate safety devices.

DANGER

CAUTION

Unauthorised changes to the machine void the attestation of conformity to
European directives by FRITSCH as well as the loss of the warranty.

All threshold limit values according to current safety
requirements must be followed; if necessary, a
ventilator must be provided or the machine must be
operated under an extractor outlet.

• Wear protective glasses!

• Wear ear protection! The noise level is above

93dB(A)

• Do not continue to use damaged accessories.

2.6 Safety equipment

Safety equipment must be used in accordance with

TIP

Inside the jaw crusher „pulverisette 1“ several elements independently acting
contribute to security:

1. Reaching into the funnel (1) is prevented by the zigzag-shaped material
passageway.

2. A safety switch (11) monitors during the operation the closing of the front cover
(10) and prevents the operation of the machine after the opening of the cover.

⇒ The switch is in accordance with the regulations for the protection of

operators.

the regulations and must not be rendered inoperative
or be removed.

All safety equipment must be checked regularly for
completeness and function.

⇒ The jaw crusher will not start if the front cover is open.
⇒ The jaw crusher will stop if the front cover is opened during operation..

2.7 Hazard points

• Crushing possibility during the closing of the front cover (10)!

2.8 Electrical safety

2.8.1 General

• The main switch (4) disconnects all-phase of the instrument from the mains.

• If the jaw crusher is not in use over a prolonged period of time, for example at

night, unplug the jaw crusher from the mains

• The machine has a motor protection switch (as per nameplate).matched to the
mains voltage
In the event of overload or a faulty motor or cable, a protection switch
automatically interrupts the flow of power. The jaw crusher can be turned back on
with the main switch (4) once the malfunction is eliminated.

• The jaw crusher is switched on and off with the main switch (4)

⇒ Turn the main switch (4) to the start position Æ : The jaw crusher starts.
⇒ By turning of the main switch (4) to the Stop position Æ, the jaw crusher:

comes to a halt after approx. 3 seconds.

⇒ The front cover (10) can now be opened.

2.8.2 Protection against warm restart

In case of Power failure, while the machine is in operation, the jaw crusher: comes
to a halt after approx. 3 seconds. Once power is restored the jaw crusher will not
start back up automatically.

⇒ The jaw crusher is protected against re-start.
⇒ Turning the main switch (4) on start position the jaw crusher will start

again.
