Jaw Crushers are used to reduce the size of many different types of materials in many applications. The Jaw Crusher was first introduced by Eli Whitney Blake in 1858 as a double-toggle Jaw Crusher. Introduced in 1906, McLanahan’s Universal Jaw Crusher was one of the first modern era overhead eccentric Jaw Crushers.
Jaw crusher is a heavy-duty machine that crushes hard materials. So its hence muse be robustly constructed. Crusher frame is made from steel or cast iron. The jaws are made of cast steel.
In order to enhance the service life of the jaw plate, upper and lower symmetrical shape jaw plate is designed into a small crusher, when the lower wear adjustable head; large jaw crusher crushing plate design pieces are symmetrical, so wear can be jaw plate changing. The jaw plate material can choose white cast iron.
White cast iron has high hardness, good wear resistance, easy source and low price, and has the disadvantages of brittleness, easy fracture and short service life. In order to improve the service life of broken plate, manganese steel containing more than 12% manganese is better, and ZGMn13. is commonly used.
In recent years, high-chromium cast iron is used for inlay casting or bonding on the high-manganese steel jaw plate to form a composite jaw plate, which has a relative wear resistance of more than 3 times, which significantly improves the service life of the Jaw Crusher Plates.
