Technical specifications
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.
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.
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
Electrical protection classes
IP 54 for motor and overload switch
IP 65 for limit switch
Rated power
750 watts

pAeq
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 L
= 90 dB(A)

Shipping and installation
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.
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.
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.
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.
At higher humidity, the electronic and mechanical
components may be damaged, and performance data
changed to an unknown extent.
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
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.
Temperature fluctuations
Intermediate storage
Also ensure that the BB 100 is stored in a dry place.
Requirements for the installation site
Ambient temperature:
5°C to 40°C
Humidity:
Maximum relative humidity 80% at temperatures up to 31°C;
linear decline down to 50% relative humidity at 40°C.
Installation site – altitude
max. 2000 m above mean sea level
