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.

http://www.construction.sandvik.com The QS441 features the world-leading CS440 gyratory cone crusher from Sandvik. The "S" type can accept a feed size up to 90% larger than current standard cones allowing maximum productivity of your primary, or even run the "S" cone as a primary crusher on gravel applications. With a choice of three concaves and four bush settings to control the closed side settings and material gradation the QS441 offers ultimate flexibility. Capable of producing large reduction ratios with minimal fines production it is ideally suited for crusher run, ballast / drainage stone or material for a tertiary crushing plant.

The essential difference is that the shorter spindle Crushers. Cross-section of heavy-duty Symons cone crusher of the cone crusher is not suspended, as in the gyratory, but is supported in a curved, universal beating below the gyratory head or cone. Power is transmitted from the source to the countershaft through a V-belt or direct drive. The countershaft has a bevel pinion pressed and keyed to it, and drives the gear on the eccentric assembly. The eccentric has a tapered, offset bore and provides the means whereby the head and main shaft follow an eccentric path during each cycle of rotation. Since a large gape is not requi...

Mantle swap operation. Displaying the problem of todays technique to lift off the mantle from the shaft. It is done by welding two metal plates with holes in them on to the big and thick mantle and then using chains and a forklift to lift it of. The weld of the plates on to the mantle can be hard to do properly because of the big difference in thickness of the two parts. So many workers around the world have been injured or killed when the weld has yielded and the workers gets crushed underneath. The small plates can be seen at 16:16 in the video, but are already put on the shaft.
