Cone Crusher Mantle High Manganese Steel Casting Wear Parts for Cone Crushing Equipment

Cone Crusher Mantle High Manganese Steel Casting Wear Parts for Cone Crushing Equipment

Our cone crusher mantle also known as moving cone liner and bowl liner also known as fixed concave liner are made of high manganese steel casting. Available grades include Mn13Cr2 Mn18Cr2 and Mn22Cr2. These wear parts form the crushing chamber inside cone crushing equipment. All castings pass UT and MT non destructive testing. Custom drawing and sample order are supported. These liners are widely used in mining quarry and aggregate production for crushing granite basalt iron ore and copper ore.

The cone crusher mantle moving cone liner and bowl liner fixed concave liner are the core consumable wear parts of cone crushing equipment. The mantle is mounted on the moving cone head and moves with eccentric gyration. The bowl liner is fixed on the inner wall of the crusher bowl. The two liners work together to form the crushing chamber. Rock and ore materials are squeezed impacted and ground repeatedly in the gap between the two liners to complete particle size reduction.

The matching of mantle and bowl liner directly affects crushing efficiency finished particle shape and liner service life. Uniform wear profile can maintain stable closed side setting and reduce frequent shutdown for replacement. We provide single mantle single bowl liner or complete set of liners according to customer requirements.

Mn13Cr2 This grade has good toughness and moderate wear resistance. It is suitable for medium abrasive stone such as limestone and soft rock materials under light impact working conditions. Mn18Cr2 This is the standard widely adopted grade. It keeps balanced wear resistance and impact resistance. It works well for granite basalt river stone and most common mine aggregates. Mn22Cr2 This is ultra high manganese steel with higher alloy content. It is designed for heavy load and high abrasive ore such as iron ore quartz and high silica hard rock. Optional TIC carbide insert can be added on high wear zones to extend service life for heavy mining conditions.

We adopt precision sand casting process for all liners. After casting the work pieces go through complete water toughening heat treatment at high temperature. The heat treatment can form stable austenite structure inside the steel. This structure creates the unique work hardening feature. When the liner bears continuous impact during operation the surface hardness rises gradually while the inner matrix keeps high toughness to avoid cracking or spalling. Every casting is processed with controlled cooling and finishing to ensure uniform wall thickness and clean internal structure.

1 Work hardening high manganese steel material. The liner surface gains higher hardness under continuous crushing impact. The inner layer remains tough to resist cracking and chipping. This characteristic brings stable service life compared with ordinary casting parts.

2 Strict heat treatment control. Complete water toughening treatment avoids brittleness and premature peeling under heavy impact load.

3 Professional non destructive inspection. UT ultrasonic testing checks internal defects such as shrinkage cavity and porosity. MT magnetic particle testing detects surface and near surface cracks. Unqualified products will be eliminated before delivery. 

4 Precision dimension control. We guarantee stable dimension tolerance after casting and finishing. The liners have good fitting performance and easy installation. No extra modification is needed for matched equipment.

5 Multiple chamber profiles available. Coarse medium and fine chamber designs can be selected to match different feeding size and finished product requirements.

6 Custom production service. We can produce non standard liners according to customer drawings samples or equipment model information.

Mining quarry aggregate plant metallurgy and cement industry. Suitable for crushing iron ore copper ore granite basalt river stone quartz and limestone. These liners can serve both stationary crushing station and mobile crushing plant.

Customers can choose proper material grade and chamber profile based on raw material hardness abrasive level feeding size and required output particle size. For heavy abrasive ore we recommend Mn22Cr2 grade or liners with TIC carbide insert. For medium rock Mn18Cr2 is the cost effective choice. Please share your working condition information so we can give proper suggestion.

Chemical composition analysis to verify alloy content Hardness and impact test to check mechanical performance UT ultrasonic testing for internal defects MT magnetic particle testing for surface crack inspection Full dimension check before packing Inspection report can be supplied together with goods or sent by electronic file.

Finished liners are packed in sturdy fumigated wooden cases to avoid damage during ocean transportation. Solid support and cushion materials are placed inside wooden cases. Trade terms FCA FOB CIF are available. We can arrange shipment according to customer requirements.
