PF1214 Rock Stone Impact Crusher With 3 Impacts Cavities For
Limestone Plant Introduction:
PF series impact crusher are designed for crushing ores and rocks
with particle sizes less than 350mm and compression strength no
more than 350MPa. It has a feature of big crushing ratio,
high-efficiency crushing, cubic shape, selectable crushing and etc.
It is suitable for crushing different compression strength of rocks
in mining, cement and concrete industries. And it is widely used to
produce fine stones for constructions of highway, airport,
building, etc.

Limestone Plant Working Principle:
PF series impact crusher machine crushes materials with impact
force. When the materials enter the blow bar area, they are crushed
due to the high speed impact of the blow bar and are thrown to the
impact plates on the rotor for secondary crush. Then the materials
will be shot back to the blow bar again for the third crush. This
process repeats until the materials are crushed to the required
size and discharged from the lower part of the machine.
The size and shape of the finished powder can be changed by
adjusting the gap between the impact rack and rotor support. The
machine employs self weigh security device in its back frame.
When other objects enter the impact cavity, they will be forced out
of the mace by the impact rack in the front and back of the
machine.
Stone Rock Breaker Impact Crusher with Blow Bar Main Structures:
The impact crusher includes a single rotor impact crusher and a
double rotor impact crusher. The structure of the single-rotor
impact crusher is relatively simple, and the material block is fed
from the feed port. In order to prevent the material block from
flying out during the crushing, a chain curtain is arranged in the
feeding direction of the feed port. The feed block falls on the top
of the stringer, and the small block falls through the quilting to
the lower part of the casing, and the bulk material slides along
the screen surface onto the rotor. A plate hammer having a certain
height is fixedly mounted on the circumference of the rotor, and
the rotor is rotated by the motor through the V-belt belt at a high
speed. The block falling on the rotor is impacted by a high-speed
rotating plate hammer. After obtaining kinetic energy, it hits the
counter-attack plate at a high speed, and then bounces back from
the counter-attack plate, and collides with the material thrown by
the rotor in the crushing zone. The space formed by the strip
screen, the rotor, the counterattack plate and the chain curtain is
called the first impact zone; the space formed between the
counterattack plate and the rotor is the second impact zone. After
the material is crushed by mutual impact in the first impact zone,
it then enters the second impact zone and is subjected to impact
pulverization again. The broken material is discharged through the
discharge port at the lower part of the casing.
One end of the counterattack is suspended from the casing by a live
chain, and the other end is fixed by an adjusting bolt. When a
large piece of material or a difficult-to-break object is caught
between the rotor and the counter-attack plate, the counter-attack
plate is subjected to a large pressure to cause a counterattack to
move backward.
