Jaw Crusher Plate Material

The heavy duty machines use in the first mechanical stage of comminution are mainly jaw crushers. The distinctive feature of this class of crusher is the two plates which open and shut like animal Jaws (Grieco and Grieco, 1985), this jaw is called jaw crusher plate. The crusher jaws are set at an acute angle such that one jaw is pivoted and the other jaw is fixed. The pivoted jaw swings around the pivot and makes the impact on the fixed jaw, crushing the fed lumps in the jaw crusher. Jaw crusher plates are the main jaw crusher parts, which need to change frequently. So it is the most important thing that how to decrease the cost. In order to decrease the replacement cost, choose the right material for your jaw crusher is the first thing. There is some material for jaw crusher plate:

High Manganese Steel

This high manganese grade is an excellent work hardening, abrasion resistant steel. This steel is a non-magnetic austenitic type, supplied in full plates or as profiled pieces by plasma cutting. Suitable for wear applications where high impact/gouging abrasion leads to a work hardening effect. High manganese steel plate becomes increasingly hard when the surfaces of components are subject to repeated impact or abrasion. Its toughness, derived from high tensile strength and ductility, enables shock leads to be absorbed safely. Lack of lubrication or the intrusion of grit or sand particles does not seriously impair the wearing surfaces of components in contact. These characteristics combine to make high manganese steel plate ideal steel for use as wearing plates in those situations where abrasion, impact, or lubrication difficulties are encountered. The steel has the unique property in service of rapidly developing a work hardened surface whilst retaining its tough interior.

High manganese steel is a steel type with Mn content of 3~27%. For casting jaw crusher plate, we use different grade to manufacture jaw crusher parts:

Mn14Cr2
Mn18Cr2
Mn22Cr2

High Manganese Chemical composition Mechanical

	Mn (%)	C (%)	Cr (%)	P (%)	S (%)	Si (%)
Mn13Cr2	11-14	1.15-1.25	1.5-2.5	≤0.05	≤0.04	0.3-0.8
Mn18Cr2	17-19	1.15-1.3	1.5-2.5	≤0.05	≤0.04	0.3-0.8
Mn22Cr2	21-23	1.1-1.4	1.5-2.5	≤0.05	≤0.04	0.3-0.8

Titanium Carbide Insert Jaw Crusher Plate

In order to prolong jaw crusher plate working life, we use titanium carbide bars insert the working face of jaw crusher liner. The crushed stone impact on the titanium carbide bars for the first time, because of the higher hardness and wearable, the composite jaw crusher plate span life can increase to 2-4 times than normal manganese steel jaw plate.
