What is a Jaw Crusher?
Jaw crushers comprise one fixed and one moving
jaw. The material is crushed between the movable jaw and the fixed jaw through
the application of compressive force produced by the elliptical motion of the
movable jaw. The movable jaw, which is supported from the top by an eccentric shaft,
is connected to the tension arm and an angled built-in support plate that
absorbs the cyclic loads in the lat section.
Jaw crushers are used as the primary crushers
in the first stage of a crushing process for the breaking of large-sized rocks,
while jaw crushers with smaller mouth openings are used to break smaller ores
into finer sizes.
Two basic jaw crushers types are produced,
being single or double-supported, depending on the movement system of the jaw.
Single headed jaw crushers are the most common type.
For what processes/applications are jaw
crushers used?
Jaw crushers are used as the primary crushers
in the first stage of the crushing process. Jaw crushers are preferred for when
breaking large rocks is the priority rather than achieving high capacity.
Jaw crushers can be used as first-stage
crushers in small- and medium-sized plants, as well as for secondary crushing
when necessary.
The oscillation distance of the jaw generally
varies between 20 and 40 mm, and the number of oscillations varies between 200
and 350 rpm. That said, the dimensions of the outlet are as important as the
inlet of the jaw crusher. Crushers can be adjusted within certain limits.
In jaw crushers, the outlet opening and jaw
movement are adjusted to suit the ore being crushed and the desired product
size. Chunks of ore crushed between the jaws descend under the force of
gravity. The greater the number of
oscillations of the jaw, the more fine product is produced. In high oscillating
crushers, the jaws open and close more often and ore does not have the
opportunity to get much distance downstream between the jaws with its own
weight and the ore is faced with more crushing force along the jaw.
What materials can jaw crushers process?
Jaw crushers are used to break up hard rocks
and moist ores of all kinds, but are not suitable for muddy applications.
In eccentric jaw crushers, the jaw facilitates
the downward movement of the ore, though these kinds of crushers are not
recommended for crushing ores with high abrasive properties, as in addition to
the compression force, the shear force provided by the horizontal movement of
the jaw is also effective.
In the jaw crushers in which compression force
is applied, the internal stresses that occur in the rock to be broken during
the crushing process are also observed in the crushed rock. For this reason,
the crushed rock produced by the jaw crusher is unsuitable as an aggregate in
concrete, especially in the construction sector. If the rocks produced by a jaw
crusher are to be used in the construction sector, the internal stresses in the
rocks should be released by breaking them up with impact or hammer crushers.
What criteria and advantages are important
in the selection of a jaw crusher?
·
These
can be used as a primary or secondary crushers, depending on the size.
·
The
use of jaw crushers in underground applications is convenient and common, as
they can be produced with few parts, and are easy to carry, assemble and
maintain.
·
There
are no capacity problems, as the desired capacity can be achieved by using more
than one crusher side by side when necessary.
·
They
are easy to maintain and affordable.
·
The
replacement of worn jaws is not time-consuming.
Useful tips for the maintenance and
operation of jaw crushers.
·
These
crushers operate with a belt pulley system. As long as the electric motor is
maintained on time and protected from dust, the probability of failure is very
low. Worn belts should be replaced with new ones at the recommended frequencies
before breaking.
·
The
recommended maintenance of moving parts at the stated intervals and the
periodic lubrication of moving parts will minimize the risk of failure of the
crusher.
·
Although
the crushers operate with a protection system, the entry of hard iron into the
crusher mouth should be avoided.
·
The
size of the material to be fed into the jaw crusher should not be larger than
80% to 85% of the crusher mouth opening. Feeders that feed material to the
crusher should be suitable both for the material size and the width of the
crusher feed opening.
·
Large
capacity jaw crushers are driven by double electric motors. To ensure
continuity in the back and forth movement of the crusher jaw and to keep the
applied force size equal, the pulleys that provide the movement are made of
large diameter, heavy, and a flywheel is attached to the opposite side of the
pulley in single-pulley crushers.
·
Jaw
crushers have a material production capacity of up to 1,000 t/h depending on
the outlet, and the reduction ratio is generally accepted as 1:5.
·
The
maximum product size is 300 mm, depending on the breaker closed part adjustment
opening.
·
Grate
or pallet feeding systems should be included in the initial investment costs of
jaw crushers.
·
Since
the vibration and load distribution are not uniform during the operation of the
jaw crushers, the concrete foundations required for assembly must be robust.
