BLOW BAR
COMPONENTS
The clamping wedges affix the blow bars and thus ensure
the proper position on the contact areas of the rotor. The
modified clamping surface provides exact fit along the
entire length, with a reduced danger of breakage.

Manganese steel
The wear resistance of manganese steel with austenitic structure is attributable to the phenomenon of work hardening. The
impact and pressure load results in a hardening of the austenitic structure on the surface.
The initial hardness of manganese steel is approx. 200 HV
(20 HRC, hardness test according to Rockwell). The impact
strength is approx. 250 J/cm.
After the work hardening, the initial hardness can thereby
increase to an operational hardness of up to approx. 500 HV
(50 HRC). The deeper-set, not yet hardened layers thereby
provide for the great toughness of this steel. The depth and
hardness of the work-hardened surfaces depend on the application and type of manganese steel. The hardened layer
penetrates down to a depth of approx. 10 mm.
Manganese steel has a long history. Today, this steel is used
mostly for crusher jaws, crushing cones and crushing shells.
In the impact crusher, it is only recommended to use manganese blow bars when crushing less abrasive and very large
feed material (e.g. limestone).
Martensitic steel
Martensite is a completely carbon-saturated type of iron that
is made by quick cooling-off. It is only in the subsequent heat
treatment that carbon is removed from the martensite, which
improves the strength and wear properties. The hardness of
this steel ranges between 44 to 57 HRC and the impact
strength between 100 and 300 J/cm.

When assessing the service life of a blow bar, further influencing factors must be taken into account in addition to the blow
bar material. The figure shows examples of the main influencing factors and the respective blow bar wear.
Generally, the various influencing factors which are mutually
interactive can be divided up into various categories.

ADVANTAGES
FACTS
APPLICATION
Factor of pre-screening
fine-particle proportion in the crusher
Depending on the properties of the feed material, active
primary screening should be used to reduce the load on the
crusher and to reduce wear. Because of the screening of the
feed material, less sticky fine material and less soiled or cohesive material ends up in the crusher; this reduces wear.

ADVANTAGES
FACTS
APPLICATION
Please note: Changing the blow bars too late will result in
increased wear on the rotor and the blow bar mounting. This
results in expensive subsequent damage and prolonged
machine downtimes. In addition to the necessary renewal of
the rotor cladding (hard facing), the clamping wedges for
blow bar mounting are also often damaged.
