Technical specifications
Machine designation: BB 100
Utilization as per the intended purpose
This unit is not designed as a production machine, but as as
laboratory device intended for 8 hours single shift operation.
The BB 100 is suitable for reducing substances of medium to
extreme hardness and for brittle and tough materials.
The ultimate fineness can be as little as 1 mm and, depending
on the material being processed, may be even less.
Maximum recommended grain size for feedstock product is 50
mm.
The following is a list of some of the materials which can be
crushed using the BB 100:
Bakelite // bauxite // concrete // dolomite // ores // feldspar
// granite // graywacke // glass // limestone // gravel // coal
// coke // corundum // quartz // salts // refractory clay //
slag // silicates // silicon // sintered materials // cement
clinker, etc.
Do not make any modifications to the machine and use only RETSCH
approved spares and accessories.
Failure to comply will invalidate the CE declaration and
guarantee.
Gap width adjustment range
From 0 to about 20 mm using a threaded spindle
Throughput rate and ultimate fineness
The performance data, throughput rate and ultimate degree of
fineness are functions of the fracture properties and the
hardness of the product being crushed and the gap width
selected. These values can only be determined empirically.
Receiver drawer nominal volume
approx. 2000 ml
Noise emissions
Noise level at a distance of 1 m:
approx. 63 dB (A) when idling
approx. 93 dB (A) when crushing marble chips measuring
3030 mm at gap width of 10 mm.
Electrical protection classes
IP 54 for motor and overload switch
IP 65 for limit switch
Rated power
750 watts

26.10.1998  Retsch GmbH 7 Doc. No .E98.052.9999
Noise emissions
Noise measurements according to DIN 45635-31-01-KL3
Characteristic noise values are dependent on the fracturing properties of
the product beeing ground.
Examples:
Workplace-related emission value LpAeq = 84 dB(A)
Operating conditions:
Sample material: marble, grain size 40 - 50 mm
Adjusted gap width: < 1 mm
Final grain size: < 5 mm
Filling ratio of grinding chamber: approx. 65 %
or
Sound power level LWA = 104 db(A)
Workplace-related emission value LpAeq = 90 dB(A)
Operating conditions:
Sample material: marble, grain size 40 - 50 mm
Adjusted gap width: < 1 mm
Final grain size: < 5 mm
Filling ratio of grinding chamber: approx. 65 %
Equipment dimensions (approximate)
Height: approx. 960 mm Width: approx. 320 mm
Depth: approx. 800 mm Weight: approx. 137 kg net
Footprint
320 mm x 800 mm; no safety clearances required!

Shipping and installation
Target groups: Owner, freight forwarder, operators
Packing
The type of packaging used has been selected in accordance
with the shipping mode. It complies with generally accepted
packaging guidelines
Please retain the packaging for the duration of the
guarantee period since, in case of a claim, returning in
unsuitable packaging can jeopardize your guarantee
entitlements.
Shipping
In preparation for shipping the BB 100, attach lifting tackle only
at the eye bolts provided for this purpose.
Refer to the section on operating controls and operation.
The BB 100 shall not be subjected to impact or vibration
during transportation; it shall not be thrown. The
electronic and mechanical components could otherwise be
damaged.
Temperature fluctuations
In case of wide temperature fluctuations (during shipment
by air, for instance) the BB 100 will have to be protected
against condensation; the electronic components could
otherwise be damaged.
Intermediate storage
Also ensure that the BB 100 is stored in a dry place.
Standard equipment
 BB 100
 1 receiver drawer, 1 grease gun (in the receiver drawer)
 1 copy of the operating instructions
Check to ensure that the shipment is complete and includes any
accessories you have ordered separately.
Verify that the BB 100 operates correctly (see in this regard the
chapter on operation).
Notify the forwarder and Retsch GmbH immediately (with-
in 24 hours) if the shipment is incomplete or damaged.
Under certain circumstances compensation cannot be paid
for claims which are lodged later.

Requirements for the installation site
Ambient temperature:
5°C to 40°C
When the ambient temperature exceeds or falls below that
specified, the electronic and mechanical components may
be damaged, and performance data changed to an unknown
extent.
Humidity:
Maximum relative humidity 80% at temperatures up to 31°C;
linear decline down to 50% relative humidity at 40°C.
At higher humidity, the electronic and mechanical
components may be damaged, and performance data
changed to an unknown extent.
Installation site –altitude
max. 2000 m above mean sea level
Fig. 1
Installation
Set up the BB 100 only on a solid, level surface. The jaw crusher
should be anchored to provide sufficient protection against tipping;
use the holes in the feet of the BB 100 for this purpose; see Fig. 1.
The vibrations transmitted to the environment by the free mass
moments in the BB 100 will be only barely perceptible.
Electrical connection
 Refer to the data plate for information on the voltage and
frequency at which the BB 100 is to be operated.
 Ensure that the values shown there correspond to those for the
local power supply.
 Use the supplied power cord to connect the BB 100 to the
power supply.
 When connecting the power cord to the power source, be sure
that the supply circuit is fused in accordance with local codes.
!
The BB 100 will not exhibit the degree of protection against
tipping prescribed in EN 61010 unless it is anchored to the
floor.
Components could be damaged.
Hazard of crushing arms and feet.
Failure to observe the values on the data plate can cause
damage to the electrical or the mechanical components or
both.
