Rock Crusher

Rock crusher is a machine designed to reduce large rocks into smaller rocks, gravel, or rock dust. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.

Rock Crusher

Rock crushing is the process of transferring a force amplified by mechanical advantage through a material made of molecules that bond together more strongly, and resist deformation more, than those in the material being crushed do.

Crushing devices hold material between two parallel or tangent solid surfaces, and apply sufficient force to bring the surfaces together to generate enough energy within the material being crushed so that its molecules separate from (fracturing), or change alignment in relation to (deformation), each other.

The earliest crushers were hand-held stones, where the weight of the stone provided a boost to muscle power, used against a stone anvil. Querns and mortars are types of these crushing devices.

Cone Crushers

Cone crushers perform well in crushing various kinds of ores and rocks of medium or above medium hardness. Cone crushers can process natural rock and reclaimed materials like concrete to produce gravel, rock dust, or rock fill.

The cone crusher is suitable for producing medium size, fine and ultrafine powders. Cone crushers are very easy to operate and the cone crusher can be easily integrated to automation systems,which can increase the machine’s overall efficiency dramatically.

Jaw Crushers

Jaw crushers are an ideal choice for primary crushing. Jaw crushers feature a high ratio of crushing, homogeneous final grain size, a simple mecahnical structure, are reliable and to easy maintain and feature a low operating cost. Jaw crushers are widely used in mining, metallurgy, construction, road building, railway, water conservancy and chemical industries.

The construction and road building industries find jaw crushers as an invaluable tool for their business.

Rock Crushers

The basic design of most rock crushers is to hold the raw material in a hopper at the top before feeding this to the crushing mechanism with a belt drive or by use of gravity. Once the material is crushed it can be discharged through the bottom opening and it can be processed further if need be. Newer generations of rock crushers offer portability and on-site stone crushing; improving production by less time lost to transporting material to fixed plants for crushing.

Some of the newer models can combine the actions of jaw crushers, cone crushers and roller crushers in to one machine as they have a wide range of compression strengths. With technological advances, industry leaders can expect higher efficiency which translates into greater cost savings.
