Jaw crusher appeared in 1858. Although it is a kind of ancient crushing equipment, but because has the advantages of simple structure, reliable work,easy to manufacture, has the advantages of convenient repair, so pew jaw crusher still in theDepartment of metallurgy, building materials, chemical industry and railway and other widely used. In metal mines, it probably used to hard or hard ore crushingand grinding. Jaw crusher is usually in accordance with the movable jaw motion characteristics to classify, the most widely used in industry there are two main types of:
1) moves double toggle mechanism is simple swing (the so-called simplependulum jaw crusher).
2) single toggle jaw swing mechanism complex (the so-called compound pendulum jaw crusher). Hydraulic technology has been used in crushing device,a hydraulic jaw crusher.
Jaw crusher process begins in the top crushing chamber and discharging port is arranged into a minimum, can make the broken than larger, designed lining steep dip that larger in the crushing cavity at the bottom of the stroke, greater ability.Precise balance design and discharge port adjusting jaw crusher features to ensure the best shortcut, economical and low running cost of crushing operation,and wide options to further improve the crushing performance. According to the user's specific requirements, options include: the pulley, the flywheel safety cover, remote control hydraulic adjustment system.
The jaw crusher is also an important sand making machine with high crushing ratio, high pass rate, and adapt to a variety of feeding conditions. The broken high speed,dynamic design perfect (large stroke, small pressure angle), and the materials can be repeatedly broken, thus improving the crushing performance. Instead of designing the blocking fixed plate greatly improves the ability of jaw crusher.
