Crusher
|
A 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. 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.

And what mechanism catches the material in a crusher machine? Asked by Carla - Wed Jun 17 22:32:26 2009 - - 1 Answers - 0 Comments A. Generally this is accomplished by catching it between jaws or rollers that move or turn together with great force. Reduction in size is generally accomplished in several stages, as there are practical limitations on the ratio of size reduction through a single stage.

Generally speaking, the discharge size of impact crusher is 20-40mm, the output size will be 0-80mm, of course, lots of them will be small than 60mm. For comparing with the old impact crusher, I can t understand, so I can t answer you. As I know, the impact crusher don t have new one or old one, just different company have different model, with different specifications. You can check this point from different company. One of my friend had bought impact crusher from Shanghai Shibang company, may be you can check from them. Answered by Jerry - Wed May 6 23:26:47 2009 From Yahoo Answer Search: "crusher" |
