3.1 Use of the Device for the Intended Purpose
Das
The Jaw Crusher BB 600 is suitable for grinding medium to medium-hard substances and brittle
and hard ductile materials.
The machine can be used to grind the following materials:
• Concrete
• Ores
• Rocks
• Glass
• Ceramics
• Coal
• Minerals
• Slag
• Cement clinker
NOTICE
N3.0007
Range of application of the device
Long-term operation
− This laboratory device is designed for eight-hour single-shift operation
with a duty cycle of 30 %.
• This device may not be used as a production machine nor is it
intended for continuous operation.
3.2 Principle of Operation
The Jaw Crusher BB 600 is tough and powerful.
The feed material passes through the splash-free hopper and into the grinding chamber.
Grinding takes place in the wedge-shaped shaft between the jaws. The feed material is
crushed and moved downwards by the elliptical motion.
The sample falls into a removable collecting receptacle as soon as it is finer than the smallest
discharge gap width.
The infinitely variable adjustment of the gap width ensures an optimum setting for the feed
material and for the desired final fineness level.
3.3 Dimensions and Weight
Height: ~1,575 mm
Width: ~1,073 mm
Depth: ~1,456 mm
Weight: ~1,300 kg net

3.4 Required Floor Space
Width of floorspace: 1,080 mm
Depth of floorspace: 1,500 mm
No safety distance is required!
A space of around 50 cm should be planned on the left-hand side of the machine for better
operability.

7.1 Switching On / Off
NOTICE The Jaw Crusher BB 600 may only be started up with an empty crushing chamber.
Grinding material placed in the crushing chamber or the feed hopper before starting the
machine will result in a blockage and possibly damage to mechanical components.
The control unit is located on the front of the Jaw Crusher BB 600, see “View of the control unit”.
Start the machine as follows:
• Turn the main switch (H) to the “ON” position and release the emergency stop button (G)
where applicable.
• Switch the machine on using the green button (F).
The motor is started up and the moving crusher arm is set in motion.
The grinding process can only be started if the drawer on the collecting receptacle (C) (see
“Front view”) has been completely pushed in. Please ensure that you close and lock the drawer
in order to prevent it slipping out due to vibrations.
When open, a limit switch prevents the machine starting (also see (C) in “Front view.
NOTICE Stop the Jaw Crusher BB 600 when there is no longer any grinding material in the
crushing chamber.
Mechanical components may be damaged by a possible blockage.
The control unit is on the front of the Jaw Crusher BB 600, see “View of the control unit”.
The machine is switched off as follows:
• Switch the machine off using the red knob (F).
• Turn the main switch (H) to the “OFF” position.
In an emergency: the machine is shut down immediately when the emergency stop button (G)
is pressed.
The motor is disconnected from the power supply and the moving crusher arm comes to a halt.

CAUTION
C9.0045
Damage to hearing
A high noise level may arise depending on the type of the material, the jaws
used and the duration of grinding
− Excessive noise in terms of level and duration can cause impairments or
lasting damage to hearing.
• Suitable sound insulation measures must be provided or hearing
protection worn.
NOTICE
N17.0003
Damage to mechanical components
Overfilling the feed hopper and the grinding chamber
− Feeding too much sample material can result in increased wear to the
jaws and wearing plates and to blockages.
• Do not use the feed hopper for storing sample material.
• Do not fill the grinding chamber to over 65% full.
• Do not exceed the specified maximum feed size for the sample
material.
• Fill larger and firmer sample material slowly and gradually into the
feed hopper.
• Pre-grind larger and firmer sample material with a larger gap where
necessary.
NOTICE Filling the crushing chamber to more than 2/3 full may damage the guide plates on the
feed hopper (A) and will result in sample material being conveyed by the activated crusher arm
into the crusher housing behind the crusher arm.
The fill volume also influences the fine share in the pre-ground sample. The fuller the crushing
chamber, the higher the fine share may be.
NOTICE With respect to the fill level, attention should also always be paid to the volume of the
collecting receptacle (D). The fill quantity must not exceed the volume of the collecting
receptacle (D).
NOTICE Only fill the feed hopper (A) and the crushing chamber when the machine is in operation.
The feed hopper (A) is not intended for storing sample material, rather its sole purpose is for
feeding the material into the crushing chamber. It furthermore prevents inadvertent access to the
crushing chamber and holds back any splashing sample material.

7.4 Removing sample material after grinding
CAUTION
C10.0005
Burns
Heating of the sample material during grinding
− Hot surfaces on the collecting receptacle or the grinding chamber can
cause burns.
− Hot sample material in the collecting receptacle can cause burns.
• Allow the hot sample material to cool down before removing the
collecting receptacle and opening the door.
• Wear protective gloves.
CAUTION
C11.0010
Heavy collecting receptacle
Depending on the density of the sample material or the filling level, the filled
collecting receptacle may be very heavy.
− Due to its weight, a filled collecting receptacle can cause personal injuries
when lifted out from the base frame.
• As a general rule, always use both hands to pull the collecting
receptacle out of the base frame.
• Two people should always remove a heavy collecting receptacle
from the base frame.
• Wear safety shoes.
NOTICE
N18.0004
Damage to mechanical components
Jaw blockage with the motor shutting down
− Due to the size and geometry of the grinding chamber, blockages may
occur when feeding a large quantity of big pieces of firmer sample
material. If the machine is not switched off in time in the event of
blockages, a motor protection switch turns the overloaded drive motor off.
• Switch the machine off immediately when there is a blockage and
remove the sample material causing the blockage.
• Reduce the feed of sample material to the feed hopper.
• Fill larger and firmer sample material slowly and gradually into the
feed hopper.
• If necessary, pre-grind larger and firmer sample material using a
larger gap width.

Serious personal injury
Contact between moving jaws in the grinding chamber
− Accidentally reaching into the grinding chamber and between moving jaws
can cause serious injuries to hands.
• Always operate the device with the feed hopper installed.
Fig. 12: Feed hopper
• Turn the Jaw Crusher BB 600 off by the main switch (H) (see “View of the control unit”).
• Disconnect the machine from the power supply and secure to prevent it restarting.
• Unscrew the four hex screws (S) around the feed hopper (A).
• Lift the feed hopper (A) up and off.
• Clean the feed hopper (A) using a damp cloth and household detergent.
• Clean the grinding chamber and jaws with a brush and vacuum the loosened material
residue with an industrial vacuum cleaner.
• The grinding chamber may alternatively be carefully cleaned with compressed air.
• After cleaning, replace the feed hopper above the grinding chamber.
• Secure the feed hopper (A) again using the four hex screws (S).
