The Best Quality Crusher Wear Parts
Crusher wear parts, which also called rock crusher replacement parts or crusher spare parts.Those parts need change and repair Cyclically. A rock crusher such as a cone crusher incorporates hardened tapered inserts in the manganese or other wear liner of at least one of its crushing elements. The inserts extend outwardly from the crushing surface of the crushing element towards the facing crushing surface so as, in use, to act as pick axes that shatter rock primarily by impact rather than pulverizing the rock by compression. The inserts are fixed in a heat treated manganese wear liner either by bonding or by press-fitting.
Crusher wear parts have many types, the mainly type included cone crusher wear parts,jaw crusher wear parts,impact crusher wear parts, gyratory crusher wear parts,hammer mill wear parts and roll wear parts.In order to keep the good wearable and hardness, most of crusher wear parts choose high manganese or chrome to cast.
Jaw crusher wear parts include fixed jaw plates,movable jaw plates, wedge plate, toggle plates and some side plates.Jaw plates are available in numerous configurations. This includes variations in tooth profiles, straight/curved jaws, and plates with filled-in ends.The crusher jaws produce better quality crushed rock more consistently than standard original equipment jaws, while reducing the need for re-screening and re-crushing.

The wear resistance of manganese steel with austenitic structure is attributable to the phenomenon of work hardening. The impact and pressure load results in a hardening of the austenitic structure on the surface. The initial hardness of manganese steel is approx. 200 HV (20 HRC, hardness test according to Rockwell). The impact strength is approx. 250 J/cm². After the work hardening, the initial hardness can thereby increase to an operational hardness of up to approx. 500 HV (50 HRC). The deeper-set, not yet hardened layers thereby provide for the great toughness of this steel. The depth and hardness of the work-hardened surfaces depend on the application and type of manganese steel. The hardened layer penetrates down to a depth of approx. 10 mm. Manganese steel has a long history. Today, this steel is used mostly for crusher jaws, crushing cones and crushing shells.
Martensite is a completely carbon-saturated type of iron that is made by quick cooling-off. It is only in the subsequent heat treatment that carbon is removed from the martensite, which improves the strength and wear properties. The hardness of this steel ranges between 44 to 57 HRC and the impact strength between 100 and 300 J/cm².Thus, with regard to hardness and toughness, martensitic steels lie between manganese and chrome steel. They are used if the impact load is too little to harden the manganese steel, and/or good wear resistance is required along with good impact stress resistance.
With chrome steel, the carbon is chemically bonded in the form of chromium carbide. The wear resistance of chrome steel is based on these hard carbides of the hard matrix, whereby the movement is hindered by offsets, which provides for a high degree of strength but at the same time less toughness. To prevent the material from becoming brittle, the blow bars must be heat-treated. It must thereby be observed that the temperature and annealing time parameters are exactly adhered to. Chrome steel typically has a hardness of 60 to 64 HRC and a very low impact strength of 10 J/cm². To prevent breakage of chrome steel blow bars, there may not be any unbreakable elements in the feed material.
Alloy steel also widly use in casting crusher wear parts. With this material, the crushed material can be dressed by magnetic separation. However, alloy steel crusher wear parts are easily break, so this material can not use to cast largest parts, only suit to cast some small parts, weight less than 500kg.
