azerbaijan Crushing force is one of the main parameters of primary jaw
crusher, and analyzing crushing force has an important guiding meaning to
improving the crushing effect of stone jaw crusher. Determining the
crushing force of a jaw crusher needs to analyze the influencing factors
which will be explained here in detail.

azerbaijan1. The mode of action on materials
used jaw stone crusher for sale sand and gravel jaw crushers in
azerbaijan The crushing of ores and rocks generally adopts mechanical
crushing method, and the modes of action of crushing machines include
crushing, splitting, bending, grinding and impacting. As for hard ores,
it is suitable to use bending and impacting for crushing; as for crisp
ores, bending and splitting will be good; as for tensile and sticky
materials, it is better to adopt grinding method for crushing. Jaw
crushing machine mainly crushes materials with crushing and bending, and
the difference of mode of action on materials determines the crushing
force.

azerbaijan2. The motion of movable jaw
used jaw stone crusher for sale sand and gravel jaw crushers in
azerbaijan The trajectory distribution of the points on movable jaw is
relatively reasonable and its horizontal throw gradually decrease along
the jaw plate of movable jaw, which can just satisfy the requirement for
increasing the amount of compression when crushing large materials, and
the lower end of movable jaw will move downward in the discharging
process. The staff of TigerCrusher Machinery introduces that the movable
jaw of jaw crusher China does complicated planar motion and the upper
movement locus is oval similar to round.
3. The property of materials
used jaw stone crusher for sale sand and gravel jaw crushers in
azerbaijan The properties of materials include stickiness, hardness and
compression strength. Different materials have different compression
strength, and the crushing force produced is also different, for this
reason, the computational formula of crushing force of PE jaw crusher
should contain the parameters of mechanical property of materials. In
addition, the particle shape of materials will also influence the
crushing force of Mini jaw crusher.
4. The movement of tooth plate
When the movable tooth plate moves, the stress on the tooth plate is
free-running on the upper and lower part, and they are opposite in some
working areas. The crushing process will produce crushing force, but the
discharging process will not produce crushing force, for this reason, the
crushing force in different working areas is different.
Analyzing the influencing factors of crushing force of jaw crushing
machine is conducive to setting up the computational formula of its
crushing force, as it is the foundation of the strength and stiffness of
the spare parts of this crushing equipment and has great significance to
ensuring normal operation of the crusher and extending its service life.
