Rock crusher is playing a very key role in railway, highway, construction, water conservancy, metallurgy and other industries. And crusher has the advantages of production stability, efficiency and environmental protection.
Ancient crushing machinery was created one after another after the gradual promotion and perfection of the steam engine and other motive power machines. In 1858, the American people Black invented jaw crusher which is capable of breaking rocks; In 1878, the United States developed spiral crusher with continuous crushing actions, and its production efficiency is higher than the jaw crusher with interval crushing actions.
American people Black designed and invented the first jaw crusher in the world. Its structural form has double bracket system, because the jaw crusher has the advantages of simple form, brief manufacturing, dependable operation, convenient keep, small volume and low height. And it is also widely utilized in crushing ore of different characteristics and various textures, such as all kinds of ores, solvents, slag, building stone and marble.
The working principle of jaw crusher is to with the aid of the pendulum motion of sewing jaw periodically near to or leave stationary lip, making the materials which enter into the crushing space proceed with extruding, splitting, bending and impact and then break. The materials after broken down depend on the downtown brought by self weight or the swing of jaw to discharge from the discharging gate. According to the trajectories of the jaw, structure form, the hanging of dynamic jaw and different support ways of bracket of dynamic jaw, jaw crusher is the crushing machinery that uses squeezing and bending function that two jaws have on materials, and coarse crushing as well as intermediate crushing materials of all kinds of types. Its broken organization composes of fixed jaw and movable jaw. When two jaws get close to the materials, they are broken. And when two jaws leave, material lump that is less than the discharge gate will discharge from the bottom part. Its crushing actions are interval.
To the 1980s, the feeding granularity of large jaw crusher that can break materials 800 tons per hour has got nearly 1800 mm. and jaw crusher that is commonly used has two kinds—double bracket and single bracket. The former is also called swing jaw crusher, while the latter does arc swing, and at the same time it also make top and bottom motion, so it is also called jaw crusher with complicated swing.
