Furthermore, due to factors such as welding, casting, heat treatment process will impact crusher.
So, we should improve the design and manufacturing process level and the use of hydraulic adjustment of the discharge opening and hydraulic insurance gradually so that domestic jaw crusher can achieve the world-class level.
Currently, we mainly aim at promoting,
developing and improving the wear-resistance of crushers by modern
technology to achieve the aim of energy saving, high efficiency, and
long service life.
There are more new types of crushers in the field of
fine crushing.
All in all, jaw crusher is used most widely among jaw
crusher, cone crusher, impact crusher and roller crusher.
The moving jaw is a much larger part of crushers with complex structure, and the structural design of jaw should depend on the force of moving jaws.
Under the conditions of meeting the strength and
hardness, the lighter of its weight, the better.
The moving force
analysis of the jaw shows that the maximum crushing force moving jaw
bearing on the side, the force is getting smaller and smaller.
In order
to be in line with the conditions of the force, but also to meet the
requirements of light weight, variable thickness can be used to
strengthen the tendons.
That relies on the ribs thickness of the upper
(head). The more down, the greater thickness.
That is, change the
original rectangular reinforcement rib to trapezoidal ribs, as this
would reduce the weight of the movable jaw and to ensure that there is
sufficient strength.
The moving jaw between the two bearing parts of the
wall thickness can be moderated to be thinner, in order to reduce
weight.
In addition, the research on the rack and the moving jaw Finite
Element Method should be strengthened to optimize the design of the
moving jaw and the rack to achieve a high degree of reliability and
light weight of the rack and moving jaw.
