Cone crushers reduce large
rocks into smaller sizes for further use in construction. Several types of
crushers are used for this purpose, and the cone crusher
is an important type that is efficient, stable, and safe.
A crusher is a mechanism that
is intended to cut big rocks into small sizes, or rock powder. Crushers are
also used to decrease the size and change the shape of waste substances for
easy disposal or recycling. Size may also be reduced for easy identification
and differentiating for further application. Crushing involves transfer of a
force that is amplified considerably by the mechanical advantage obtained
through materials whose molecules are bonded strongly. These molecules offer
greater resistance to deformation, compared to the materials that are being
crushed. Crushing tools hold the material to be crushed between two solid
surfaces that are parallel. Force is applied to bring these surfaces close to
each other. Sufficient energy is generated inside the material that is being
crushed, and consequently the molecules are separated. The initial crushers
were stones held by hands, and the stone weight amplified the human power.
The cone crusher
is a machine used in the construction industry for crushing different varieties
of rocks and ores of varying hardness. Cone crushers have a stable structure,
an efficient and simple adjustment, and are used extensively. The crusher
functions by pushing on substances held between the fixed cone and the movable
cone. The cone crusher splits the rocks by
clutching them between an eccentric rotating spindle that is enclosed by a
tough layer, and a concave hopper. As the rocks enter the crusher, they are
wedged between the layer and the concave hopper. Big pieces are broken, and
then these are dropped to another position, where the breaking process is
repeated. This procedure is continued until the rocks are small enough in size
to descend through the restricted opening at the crusher bottom.
The cone crusher
is fitted with a spring release safety system that performs as an overload
safety device. It permits extremely hard materials to move through the chamber
without damaging the crusher. The safety arrangement utilizes water and dry oil
to produce plaster powder for preventing the movement of hard objects.
Furthermore, to ensure reduction of the stresses on crusher parts, the loads
are distributed equally over a big enduring area. Springs are incorporated as
safety features to avoid damage during the cone crusher
operation. These springs exert pressure on the top frame. If some pieces that
cannot be crushed enter the system, the springs activate the liner to rise and
prevent damage.
