Cone Crusher Mantle and Bowl Liner High Manganese Steel Cast Wear Parts

Cone Crusher Mantle and Bowl Liner High Manganese Steel Cast Wear Parts

Short Description

Cone crusher mantle also known as moving cone liner and bowl liner also known as fixed concave liner are core wear resistant castings for cone crushing equipment. Made of premium high manganese steel with multiple material grades these two parts work together to form the crushing chamber. Every casting goes through strict non destructive testing to remove internal and surface defects. Custom production based on drawings samples and size requirements is available. These liners serve mining quarry aggregate processing and stone crushing operations for handling various hard rock and ores.

Product Overview

Mantle and bowl liner are a matched set of consumable components inside cone crushing equipment. The mantle is mounted on the moving cone head and moves with eccentric gyratory motion during operation. The bowl liner is fixed on the inner wall of crusher frame. Material is squeezed impacted and ground repeatedly in the gap between these two liners to finish particle size reduction.

The matching condition of mantle and bowl liner directly influences crushing efficiency finished stone shape and service life of wear parts. A well matched liner set keeps stable crushing gap and reduces frequent shutdown for replacement. We can supply single mantle single bowl liner or complete liner set according to customer actual site needs.

Material Grade Introduction

We provide multiple material options to fit different raw material hardness and abrasion conditions Mn13Cr2 This grade has good toughness and moderate wear resistance. It suits light and medium impact working conditions and medium abrasive materials including limestone and soft rock. Mn18Cr2 This is the widely used standard grade with balanced impact resistance and wear performance. It works well for granite basalt river stone and construction aggregates in most quarry and mine production lines. Mn22Cr2 This enhanced high manganese steel contains higher alloy content. It is designed for heavy load and high abrasive working conditions such as iron ore copper ore and high silica quartz stone to resist strong impact and abrasive wear. Carbide Reinforced Version Optional local carbide strengthening on high wear areas can greatly improve local wear resistance for long term heavy mining production.

Production and Processing Technology

All liners adopt precision resin sand casting technology to get compact internal structure and clean casting surface without sand holes or loose structure. After high temperature casting all workpieces carry out complete water toughening heat treatment.

Heat treatment optimizes the internal metallographic structure of high manganese steel and forms stable austenite matrix. The material has special self hardening property. Continuous impact force during crushing gradually hardens the working surface while the inner matrix remains high toughness. This feature effectively prevents cracking peeling and block dropping under cyclic heavy load.

All finished castings go through manual finishing shape correction and full dimension inspection to guarantee assembly accuracy and good matching performance.

Product Performance Advantages

• Self hardening property brings stable working performance under continuous impact crushing environment
• High toughness base material reduces crack risk under heavy impact load
• Uniform wall thickness design supports even wear and keeps stable finished particle size
• Strict non destructive testing removes hidden defects including internal porosity shrinkage cavity and surface micro cracks
• Precise dimension control so no extra cutting or modification is required during on site installation
• Multiple chamber types including coarse medium and fine to meet different feeding size and output requirements
• Optimized liner curve design improves material flow inside crushing chamber and reduces material blocking
• Reduce unplanned plant shutdown and cut overall operation cost for crushing sites

Application Range

Suitable for medium and fine crushing of various hard stones and ores. Widely used in mining quarry aggregate plant road construction material yard metallurgy and cement industry. The liner set can be used on stationary crushing production line and mobile crushing station.

Quality Inspection Standard

We carry out full process quality control from raw material incoming check to finished product delivery Raw material chemical composition analysis Hardness and impact test for mechanical performance verification Ultrasonic inspection for internal structural defects Magnetic particle inspection for surface micro crack detection Full size dimension measurement and record keeping

Complete inspection records and quality reports can be provided for customer review.

Packing and Delivery

Mantles and bowl liners are packed in solid fumigated wooden cases. Anti collision cushion materials are placed inside packages to avoid damage during long distance sea transportation. We support flexible trade terms such as FCA FOB and CIF to match different customer logistics plans.
