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.
Purpose of a Crusher
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.
Cone Crusher Functioning
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.
Cone Crusher Safety Mechanism
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.
