In industry, crushers are machines which use a metal surface to break or compress materials into small fractional chunks or denser masses. Throughout most of industrial history, the greater part of crushing and mining part of the process occurred under muscle power as the application of force concentrated in the tip of the miners pick or sledge hammer driven drill bit. Before explosives came into widespread use in bulk mining in the mid-nineteenth century, most initial ore crushing and sizing was by hand and hammers at the mine or by water powered trip hammers in the small charcoal fired smithies and iron works typical of the Renaissance through the early-to-middle industrial revolution.

Impact stone crusher is a new type of high-efficiency crushing equipment which developed by absorbing domestic and foreign advanced technology and combining with mining conditions of domestic industry. The operator feeds chunks of material into the machine's hopper and it crushes them, turning the pieces into small chunks of a more uniform size. They can be run through another crusher to make them even smaller, or used as-is, depending on the setting. Numerous companies manufacture impact crushers, including large stationary models, as well as portable equipment for job sites.

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.

Impact stone crusher in China are widely applied in metallurgy, building materials, chemical industries. They are ideal for crushing medium hard brittle materials of coarse, secondary and fine crushing stages, such as limestone, dolomite, sandstone, graphite, rock salt, granite and basalt. Fote series impact stone crusher have such advantages as high reduction ratio, unequaled output, uniform production size, compact process, simple construction, easy operation and maintenance.
