Impact Crushers
General
Features
Mode of Operation
Hammers & Crushing Ledges
TRF Impact Crushers are ideal processing machines for
primary and secondary crushing of raw materials for the steel
and iron industry, hard coal and lignite, limestone, gypsum or
minerals. These are also extensively used for the tertiary
crus hing of limestone, dolomite, dunite for the Bedding and
Blending Plant for sinter preparation and coal for Coking
Plant. Its sturdy and proven design offers the following
advantages :
= increased throughout capacity
= maximum possible operating reliability
= mainly unaffected by foreign bodies
= low maintenance cost
1. Crushing ratio can be set at an extremely large value :
normally at 20 and maximum up to 80.
2. A high crushing efficiency reduces the power
consumption.
3. Selective crushing can be made with ease.
4. The shape of crushed material will increasingly
become cubic.
5. Mechanism and operation are simple.
6. Safety running is assured.
7. Lighter in machine weight as against capacity,
saving installation cost.
TRF manufactures various types of Impact Crushers and
hence is in a position to offer the most suitable Crusher
required for the specific duty condition.
Impact Crusher (Type TA with two Part
Hammer Arrangement)
The feed material is crushed by means of rotating beaters with
renewable heads by impact against the grinding ledges. Due
to the reversible rotor with crushing ledges arranged on both
sides the wearing face of the hammer heads can be used to
the maximum possible extent without reversing the hammers.
The machine is provided with central inlet and open discharge
which eliminates the chances of clogging of grate opening.
The rotor of the crusher consists of a forged heavy duty rotor
shaft and machined rotor discs keyed to the shaft. The rotor
is provided with two part hammer arrangement consisting
of Hammer arms and hammer heads which are arranged
around the circumference of the rotor in a staggered
manner. The quantity of hammers per row is decided
depending on the duty requirement. The locating holes for
the hammer arms are drilled on special device with high
precision pitch thus eliminating the vibration when the
machine is running.
The hammer heads on the hammer arms are reversible
and can be worn down to 70% of their original size.
The impact walls are arranged around the rotor and are
equipped with renewable grinding ledges of wear resistant
cast material. The final product of the crusher can be
altered by adjusting the distance between the rotating
hammer heads and the impact walls. At the same time the
adjustment serves for the compensation of wear.
In the standard design, the adjustment of the impact walls
can be earned out while the machine is running by
regulating the screws on the upper part of the housing
while the lower adjustment is effected by means of a
ratchet and worm gear.
The housing of the Impact Crusher is divided into parts and
can be opened hydraulically (or mechanically) on the left
and right side of the rotor. Thus, all wearing parts become
accessible and can be easily replaced. The housing is also
provided with large inspection doors allowing quick
inspection of the inside condition of the machine.
Impact Crushers (type TE With Single
Piece Hammer Arrangement)
Material driven against breaker blocks rebounds and is
again struck by the hammers, shattering under this high
velocity impact. Small, finished particles cease to react
freely to additional hammer blows and are swept from the
active reduction zone.
By this maximum crushing power is applied to large
fragments while little energy is expended on finished
particles. The impactor is ideally suited to the closed circuit
crushing system to obtain maximum crushing efficiency.

The hammer heads on the hammer arms are reversible
and can be worn down to 70% of their original size.
The impact walls are arranged around the rotor and are
equipped with renewable grinding ledges of wear resistant
cast material. The final product of the crusher can be
altered by adjusting the distance between the rotating
hammer heads and the impact walls. At the same time the
adjustment serves for the compensation of wear.
In the standard design, the adjustment of the impact walls
can be earned out while the machine is running by
regulating the screws on the upper part of the housing
while the lower adjustment is effected by means of a
ratchet and worm gear.
The housing of the Impact Crusher is divided into parts and
can be opened hydraulically (or mechanically) on the left
and right side of the rotor. Thus, all wearing parts become
accessible and can be easily replaced. The housing is also
provided with large inspection doors allowing quick
inspection of the inside condition of the machine.
Impact Crushers (type TE With Single
Piece Hammer Arrangement)
Material driven against breaker blocks rebounds and is
again struck by the hammers, shattering under this high
velocity impact. Small, finished particles cease to react
freely to additional hammer blows and are swept from the
active reduction zone.
By this maximum crushing power is applied to large
fragments while little energy is expended on finished
particles. The impactor is ideally suited to the closed circuit
crushing system to obtain maximum crushing efficiency.

General
Features
Mode of Operation
Hammers & Crushing Ledges
TRF Impact Crushers are ideal processing machines for
primary and secondary crushing of raw materials for the steel
and iron industry, hard coal and lignite, limestone, gypsum or
minerals. These are also extensively used for the tertiary
crus hing of limestone, dolomite, dunite for the Bedding and
Blending Plant for sinter preparation and coal for Coking
Plant. Its sturdy and proven design offers the following
advantages :
= increased throughout capacity
= maximum possible operating reliability
= mainly unaffected by foreign bodies
= low maintenance cost
1. Crushing ratio can be set at an extremely large value :
normally at 20 and maximum up to 80.
2. A high crushing efficiency reduces the power
consumption.
3. Selective crushing can be made with ease.
4. The shape of crushed material will increasingly
become cubic.
5. Mechanism and operation are simple.
6. Safety running is assured.
7. Lighter in machine weight as against capacity,
saving installation cost.
TRF manufactures various types of Impact Crushers and
hence is in a position to offer the most suitable Crusher
required for the specific duty condition.
Impact Crusher (Type TA with two Part
Hammer Arrangement)
The feed material is crushed by means of rotating beaters with
renewable heads by impact against the grinding ledges. Due
to the reversible rotor with crushing ledges arranged on both
sides the wearing face of the hammer heads can be used to
the maximum possible extent without reversing the hammers.
The machine is provided with central inlet and open discharge
which eliminates the chances of clogging of grate opening.
The rotor of the crusher consists of a forged heavy duty rotor
shaft and machined rotor discs keyed to the shaft. The rotor
is provided with two part hammer arrangement consisting
of Hammer arms and hammer heads which are arranged
around the circumference of the rotor in a staggered
manner. The quantity of hammers per row is decided
depending on the duty requirement. The locating holes for
the hammer arms are drilled on special device with high
precision pitch thus eliminating the vibration when the
machine is running.
The hammer heads on the hammer arms are reversible
and can be worn down to 70% of their original size.
The impact walls are arranged around the rotor and are
equipped with renewable grinding ledges of wear resistant
cast material. The final product of the crusher can be
altered by adjusting the distance between the rotating
hammer heads and the impact walls. At the same time the
adjustment serves for the compensation of wear.
In the standard design, the adjustment of the impact walls
can be earned out while the machine is running by
regulating the screws on the upper part of the housing
while the lower adjustment is effected by means of a
ratchet and worm gear.
The housing of the Impact Crusher is divided into parts and
can be opened hydraulically (or mechanically) on the left
and right side of the rotor. Thus, all wearing parts become
accessible and can be easily replaced. The housing is also
provided with large inspection doors allowing quick
inspection of the inside condition of the machine.
Impact Crushers (type TE With Single
Piece Hammer Arrangement)
Material driven against breaker blocks rebounds and is
again struck by the hammers, shattering under this high
velocity impact. Small, finished particles cease to react
freely to additional hammer blows and are swept from the
active reduction zone.
By this maximum crushing power is applied to large
fragments while little energy is expended on finished
particles. The impactor is ideally suited to the closed circuit
crushing system to obtain maximum crushing efficiency.

Impact Crusher [ type HB With Hammer
Bar Arrangement
Rotor
Hammer Bars
TRF Hammer Bar type Impact Crushers are suitable for
crushing hard rocks such as limestone, dolomite, granite and
other similar materials under toughest operating conditions.
The rotor is made of high-carbon steel casting, and has
wedge-shape hammer holding grooves extending parallel to
the shaft. Its peripheral part is hardened by high frequency
induction heating for greater wear resistance. The shaft is
press fitted and the rotor shaft assembly is dynamically
balanced to assure vibration free operation.
The hammer bars extend over the full width of the rotor. The
bars are so designed that these can be reused by
repositioning after one face wears out. The hammer bars are
of Mn steel castings.
Two or three Breaker plates of Mn Steel casting are
positioned to form an arc of the circle centered to the point of
impact. The first plate is normally fixed in initial crushing
zone. The second and the last plates are suspended from
the frame through hinged connections. These are adjustable
by heavy duty coil spring.
The frame is fabricated with heavy steel plates and is stress
relieved. Inside surface of the frame is provided with cast Mn
steel liners.
