Crushers use force to reduce the size of objects, either by compacting or breaking them into smaller pieces. They are used in a variety of applications, from reducing the size of aluminum cans to scientific research and mining operations. Larger, automated crushers are used in industrial settings and can be expensive.
Crusher are devices designed to reduce the size of larger objects by using force to reduce objects into a smaller more compact volume. This is sometimes achieved by compacting the object’s mass. Other times, the crusher will use force to break the object into a series of smaller pieces.
The action of any type of crusher makes use of force as a means of accomplishing the task of crushing objects. In essence, crushing involves the transfer of force that is augmented by mechanical advantage and will therefore distribute the force along the body of the object. This usually involves placing the object between two solid surfaces. One of the surfaces acts as a platform and provides a location to place the object. The second surface is usually above the object and platform and slowly lowers to exert a force on the object. As the force crushes the object, the top surface continues to descend until an optimal degree of size reduction has occurred.
Crushing is useful in a variety of applications. In the home, a small hand crusher is often used to reduce the size of aluminum cans. This action allows crushed cans to be stored until enough is collected for transport to a recycling facility. Hand mills of this type are often very inexpensive and take up no more space than a standard countertop kitchen appliance.
A crusher can be used to break things like rocks. Crusher of this type are often used in scientific research, as they allow a larger sample of rock to be crushed into smaller pieces and then examine the rock contents in more detail. At the same time, an ore crusher is sometimes used in mining operations as a means of assessing the ore content extracted from a particular excavation site.
The larger crushers are automated and perform more complex jobs. Mechanical crushers are often employed in automotive junkyards. Once all serviceable components have been removed from the vehicle, the remaining carcass of the car or truck is loaded into a large crusher which will reduce the size of the vehicle to a fraction of its original size. The crushed vehicle can then be recycled into other useful products. A crusher of this type is intended for mass use in an industrial setting and is normally very expensive.
