The jaw crusher has been specially developed for sample preparation in the
laboratory.
It is used for the fast and gentle grinding and pre-crushing of medium-hard, hard,
brittle and tough materials.
The final fineness that can be achieved can be up to 0.5 mm or below depending
on the feed material.
The maximum feed size is 40 mm.
Materials that can be ground in the BB 50 include the following:
Bakelite
Bauxite
Basalt
Concrete building

Dolomite
Ores
Feld spar
Granite
Rubblestone
Glass
Limestone
Ceramic

Properties of the grinding material
In principle every hard and brittle grinding material with hardness grade >3
according to the Mohs scale can be ground using this machine.
Damp, greasy grinding material and grinding material with a hardness grade <3
according to Mohs tends to compact or cake in the crushing chamber under the
applied pressure. Grinding these products by fracturing and applying pressure is
not possible.
Small sample quantities are ground gently and without loss. This machine is
available with a grinding chamber made from ceramic materials for heavy metal-
free grinding. The digital grinding gap display and the zero point alignment of the
machine enable reproducible grinding results.
