Fine Machined Wear Resistant High Manganese Steel Grate Discharge Liner

High manganese steel crusher grate screen plate is manufactured with wear-resistant alloy material and serves as a durable replacement part for mining crushing equipment

Product Overview

Our crusher grate plate is a critical wear-resistant spare part engineered for hammer crushers and impact crushers, widely used in mining, quarrying, aggregate processing, cement plants, and material recycling industries.

Manufactured from high-manganese steel casting, this grate plate delivers exceptional toughness, strong impact resistance, and superior anti-abrasion performance. Under continuous heavy impact and material friction, it maintains a long service life, significantly reducing replacement frequency and lowering overall operating costs.

Key advantage: Under heavy impact, the surface layer rapidly work-hardens while the core remains tough, providing an ideal balance of wear resistance and fracture resistance – a unique property of high-manganese steel that extends service life by 20–30% compared to standard cast steel plates in high-impact applications.

Precision Manufacturing & Structural Design

Each piece is produced through a rigorous precision casting process with a scientifically optimized structure. The discharge slots are precisely machined to ensure accurate control of final output particle size. Reinforced mounting lugs and bolt holes guarantee stable installation and firm fixation inside the crushing chamber, effectively preventing deformation or fracture during high-intensity production.

Customization & Compatibility

We support OEM & ODM customization. Products can be manufactured strictly according to customer drawings, samples, or size requirements.

Our grate plates are designed to fit most mainstream crushing equipment on the market. To ensure precise compatibility, please provide your machine model and original part drawing or number – our engineering team will verify and match accordingly.
