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 200
Utilization in accordance with the intended purpose
The BB 200 is suitable for reducing medium-hard to very-hard
substances as well as for brittle and tough materials.
The ultimate fineness can be as little as 2 mm and, depending on
the material being processed, may be even less.
The following is a list of some of the materials which can be
ground using the BB 200:
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 30 mm using a threaded spindle
Throughput rate and ultimate fineness
The performance data, through-put rate and attainable ultimate
fineness are dependent on the fracturing properties and the
hardness of the product being ground. These values can only be
determined empirically.
Receiver drawer volume
approx. 5 dm3
Noise emissions
Noise level at a distance of 1m:
approx. 63 dB (A) when idling
The noise level can rise depending on the product being
processed.
Electrical protection class
IP54
Rated power
1500 Watt

Noise emissions
!
Damage to hearing
The level of noise can be high depending on the type of
material the duration of the grinding process.
- Noise that is excessive in terms of level and duration
can cause impaired or permanently damaged hearing.
• Ensure suitable sound-proofing measures or
wear hearing protection.
Height: 1160 mm
Width: 450 mm
Depth: 900 mm
Weight: 300 kg net
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 L
= 84 dB(A)
pAeq
Operating conditions:
Sample material: marble, grain size 40 - 80 mm
Adjusted gap width: < 1 mm
Final grain size: < 5 mm
Filling ratio of grinding chamber: approx. 65 %
or
Sound power level LWA = 101 db(A)
Workplace-related emission value L
= 92 dB(A)

Shipping and installation
Please retain the packaging for the duration of the
guarantee since, in case of a claim, returning in unsuitable
packaging can jeopardize your guarantee entitlements.
The BB 200 shall not be subjected to impact or vibration
during transportation; it shall not be thrown. The
electronic and mechanical components could otherwise be
damaged.
Abb.1
In order to be able to transport the BB 200 with a crane
(capable of lifting at least 500 kg), it should be fixed with
ties as in figure 1.
Intermediate storage
Please pay attention to the fact that the BB 200 must also
be kept dry when in intermediate storage.
In case of wide temperature fluctuations (during shipment
by air, for instance) the BB 200 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.
Packing
The type of packaging used has been selected in accordance with
the shipping mode. It complies with generally accepted
packaging guidelines.
Shipping
Temperature fluctuations
Intermediate storage
Also ensure that the BB 200 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
