Gyratory Crusher Mantles Material Selection

Different working conditions, different crush materials, different types, need different materials of crusher mantles to suit. Qiming Machinery supplies the following materials based on our special design or customer inquiry.

Three Kinds Materials For Gyratory Crusher Mantles

1. Manganese Steel

There are three kinds of manganese steel (Mn14, Mn18, and Mn22) use to cast gyratory crusher mantles.  It is a traditional material. However, this material is a little soft, can not get along working life in crushing hard stone

2. Manganese Alloy Steel

In order to get longer service life in crush hard stone, we add some elements in manganese steel. Such as we add the “Cr” element to increase the hardness, add the “Mo” element to get a better austenite structure…

This manganese alloy steel grades include:

• Mn14Cr2
• Mn18Cr2
• Mn22Cr2
• Mn18Cr2MoNi
• Mn22Cr2MoNiV

3. TIC Insert Manganese Steel

This material is our foundry patent product. We use titanium carbide bars inserts the gyratory mantles crushing surface area. Under this design, its span life can be 1.5-2 times that of normal manganese steel.

Standard material for gyratory crusher mantles

The first choice of material for standard mantles is the Mn14Cr2. To further maximize performance and wear life, special designs and high-alloy options are also available. Please check the following tab or contact our engineers to help you.
