The standard cone crusher mantle and concave ring material is manganese, but depending on the feed characteristics a variety of other alloys can be chosen to achieve the best cost per produced ton. The upper concave tiers must withstand high impact forces. The lower tiers require maximum abrasion resistance. There are some kinds of material selection:
1. High Manganese Steel
Manganese is essential to iron and steel production by virtue of its sulfur-fixing, deoxidizing, and alloying properties, as first recognized by the British metallurgist Robert Forester Mushet (1811–1891) who, in 1856, introduced the element, in the form of Spiegeleisen, into steel for the specific purpose of removing excess dissolved oxygen, sulfur, and phosphorus in order to improve its malleability. Steelmaking, including its ironmaking component, has accounted for most manganese demand, presently in the range of 85% to 90% of the total demand. Manganese is a key component of low-cost stainless steel. Often ferromanganese (usually about 80% manganese) is the intermediate in modern processes.
Small amounts of manganese improve the workability of steel at high temperatures by forming a high-melting sulfide and preventing the formation of a liquid iron sulfide at the grain boundaries. If the manganese content reaches 4%, the embrittlement of the steel becomes a dominant feature. The embrittlement decreases at higher manganese concentrations and reaches an acceptable level at 8%. Steel containing 8 to 15% of manganese has a high tensile strength of up to 863 MPa.Steel with 12% manganese was discovered in 1882 by Robert Hadfield and is still known as Hadfield steel (Mangalloy). It was used for British military steel helmets and later by the U.S. military.
The Type of High Manganese Steel For Concave and Mantle
2.TIC Insert Manganese Steel
Titanium Carbide (TiC) cone crusher wear parts are designed to increase the wear life of wear parts in abrasive environments. Titanium carbide columns are cast within proprietary alloys for added strength and durability.
Under this material, Concave and mantle working life can be 2-3 times than normal high manganese steel parts. Especially, when crushing hard stone, its span life can be more time.
3.High Mn Steel Matrix Ceramic Composite
High Mn Steel matrix ceramic composite concave and mantle had tested in many customers who use cone crusher to crush hard stone, its span life also better than normal manganese steel.
In fact, there are many kinds of material for cone crusher concave and mantle, which material is the best? Its based on the cost performance and real quality inquiry.
