High Wear Resistant Ball Mill Liner Cast Steel Mining Mill Lining Plate

Ball Mill Liner High Wear Resistant Cast Steel Mining Mill Lining Plate

Short Description

Ball mill liner is the core wear resistant protective component installed inside rotary grinding mills. It serves to protect the mill cylinder body adjust grinding medium movement trajectory and improve grinding efficiency. Our mill liners are manufactured with high manganese steel high chromium alloy and customized composite casting formulas. All products undergo professional heat treatment and full non destructive testing. Suitable for mineral processing cement production aggregate grinding and industrial fine grinding applications. Custom structural shapes thickness and material grades are available for different mill models and working conditions.

Product Technical Overview

Ball mill liners bear continuous high impact abrasive wear and material scouring during long term rotary grinding operation. Different from common static wear parts mill liners work under cyclic dynamic load repeated ball impact ore friction and high speed material sliding. Their structural design material toughness and surface hardness directly determine mill stability downtime frequency and overall operation cost.

Our factory adopts optimized casting structure and precise heat treatment technology to balance surface wear resistance and matrix toughness. The liners maintain stable mechanical performance under long continuous running avoid brittle cracking peeling deformation and excessive uniform wear effectively extending service life and reducing frequent replacement cycles.

Professional Material Grade Classification and Working Condition Matching

We provide multi dimensional material solutions to adapt to light medium and heavy grinding scenarios

High Manganese Steel Mn13Cr2 This grade features excellent work hardening performance and ultra high toughness. Under continuous impact of steel balls and ores the working surface gradually forms a high hardness hardened layer while the inner matrix remains strong toughness. It effectively resists impact cracking and fatigue damage suitable for medium hardness ore general mineral grinding and cement raw material grinding.

High Manganese Steel Mn18Cr2 Enhanced alloy manganese steel with higher chromium and carbon ratio. It improves overall wear resistance while retaining excellent impact resistance. Suitable for high output mining processing plant hard stone grinding and continuous high load mill operation.

High Chromium Alloy Steel High hardness microcrystalline alloy structure with excellent anti scouring and anti abrasive performance. It greatly reduces uniform wear speed ideal for fine grinding high purity material grinding and low impact high friction working conditions.

Composite Strengthened Liner Local carbide or high alloy strengthening on high wear areas combining high toughness matrix and super wear resistant surface. It solves the problem of partial rapid wear and greatly prolongs overall service life for heavy duty mining grinding.

Structural Design Characteristics

We supply multiple liner structural types including wave liner step liner rib liner flat liner and custom curved liner profiles. Different structures scientifically adjust the lifting height falling track and rolling state of grinding media.

Wave and step liners improve lifting capacity of steel balls enhance impact crushing effect for coarse materials and increase mill output. Flat and rib liners optimize material sliding performance improve fine grinding fineness and reduce over grinding phenomenon. Reasonable structural matching stabilizes particle size distribution improves grinding uniformity and reduces energy consumption per ton of material.

Advanced Manufacturing and Heat Treatment Technology

All mill liners adopt precision resin sand casting process with compact internal structure no sand holes no porosity and no loose grain defects. After high temperature integral casting all workpieces undergo strict water toughening heat treatment and controlled cooling process.

The heat treatment process refines internal metallographic structure eliminates casting internal stress and obtains uniform stable austenite structure. This technical process ensures the liner has strong impact fatigue resistance avoids early cracking and layer peeling under long term cyclic load and realizes continuous self hardening during grinding operation.

All finished products are processed by precise trimming surface finishing and full dimension calibration to ensure installation fitting gap and overall assembly consistency.
