Gyratory Crusher Wear Parts Foundry- Qiming Machinery®

When it comes to gyratory crusher wear parts, Qiming Machinery had manufactured jaw crusher wear parts over 30 years. The primary gyratory crusher wear parts have the most important role in rock size reduction in mine operations as the crushing process starts from a primary crusher. The highest possible wear life is combined with mechanical reliability through the component life cycle.

Our engineers are committed to understanding your specific needs and refining a solution to help you. To us, that means direct communication with you to get a full understanding of your wear part needs and on-site consultation if necessary. We have a wide range of gyratory crusher wear part designs in our database to choose from and customize.

Gyratory crusher wear parts include:

  • Gyratory crusher mantle
  • Gyratory crusher concave segments

Qiming Machinery proprietary alloys and innovative designs result in longer wear life compared to other OEM replacements.

Gyratory Crusher Mantles Designs

Qiming Machinery is one of the largest casting foundries in China. For gyratory crusher mantles, no matter one-piece, two pieces, or three pieces design; no matter smooth tooth or full tooth design; no matter 10 tons or 15 tons of mantles weight; Qiming Machinery’s engineers will help you to the right designs.

Except for manufacturing mantles based on customer drawings, our engineers also go to the gyratory crusher working place and help our customers to design or modify those mantles. For example, a mantle new designed with a toothed top and heavy-duty bottom can improve initial grip and put more metal in the high wear area of the crushing cavity.

 

Mantles Material Selection

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

Manganese Steel

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

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 better austenite structure…

This manganese alloy steel grades include:

  • Mn14Cr2
  • Mn18Cr2
  • Mn22Cr2
  • Mn18Cr2MoNi
  • Mn22Cr2MoNiV

TIC Insert Manganese Steel

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

 

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.

Gyratory Crusher Concaves Designs

Normally, gyratory crusher concaves are designed to 3 layers structure. The first layer and second layer are made by high chromium alloy steel, the third layer is manufactured by high manganese steel. Qiming Machinery is one of the largest gyratory crusher wear parts foundries in China. We have rich experience in casting gyratory crusher concaves with manganese and chromium steel, on the other hand, our engineers had improved the casting material. We use WS7 alloy steel to cast the first and second layers, this material Initial hardness more than 700 HBN, which is higher than chromium steel; Use WS5.5 alloy steel to cast the third layer, which impact and wear resistance better than manganese steel concave liners.

If you use popular brands gyratory crushers, send us the drawings or ask our engineers to help you to measure the drawings. All of our crusher concaves are designed to fit your plant.

 

Gyratory Crusher Concaves Structure

There are 3 layers of design in gyratory crusher:

Upper Intake Liners

  • Manganese alloys or WS5.5 alloy steel
  • Low-alloy steel, impact-resistant

Chamber Mid Liners

  • High manganese alloys or WS5.5 alloy steel
  • Low-alloy steel, abrasion and impact resistant

Chamber Bottom Liners

  • Low-alloy- steel, high abrasion, and impact resistant or WS7 alloy steel
  • High-chrome special, maximum abrasion resistance

 

Gyratory Crusher Concaves Material Selection For Different Stone

The standard concave alloy 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.
