Impact Crusher Wear Plate

Impact Crusher Wear Plate – Product Introduction

Overview

Impact crusher wear plates (also called impact liners, breaker plates, or apron liners) are critical wear-resistant components installed inside horizontal shaft impact (HSI) crushers. They are bolted to the crusher’s housing, side walls, and impact aprons, designed to absorb high-velocity material impacts, protect the mainframe from abrasion, and control product gradation. As the second-line crushing elements, they work with blow bars to ensure efficient, consistent reduction of rock, ore, and recycled materials.

Key Functions

• • Impact Absorption: Withstand repeated high-energy collisions from materials thrown by the rotor blow bars.
• • Body Protection: Shield the crusher’s mild-steel housing and frame from severe wear and structural damage.
• • Material Rebounding: Bounce crushed material back into the crushing chamber for secondary impact, improving crushing efficiency.
• • Gradation Control: Maintain precise gaps to ensure consistent product size and reduce oversize material.
• • Easy Replacement: Bolt-on design enables quick, safe changeouts to minimize downtime.

Material Options

We offer a range of high-performance alloys to match different feed materials and abrasion levels:

1. 1. High Manganese Steel (Mn18Cr2, Mn22Cr2)
   • • Features: Excellent impact toughness, work-hardening under load.
   • • Best for: Soft to medium, low-abrasion materials (limestone, concrete recycling).
2. 2. High Chromium Cast Iron (Cr26, Cr28)
   • • Features: Superior hardness (58–65 HRC), high abrasion resistance.
   • • Best for: Hard, abrasive rocks (granite, basalt, iron ore).
3. 3. Martensitic Steel (with or without ceramic inserts)
   • • Features: Balanced impact strength and wear resistance; ceramic-reinforced versions deliver 2–4× longer life than standard steel.
   • • Best for: Heavy-duty, high-volume crushing (quarries, cement plants).
4. 4. Custom Alloys: Tailored chemistries for specific applications (e.g., high-silica sand, corrosive ores).

Product Features & Advantages

• • Precision Casting & CNC Machining: Ensures accurate dimensions, perfect fit, and consistent performance.
• • Optimized Profile Design: Smooth or baffled surfaces available; adjustable configurations for precise nip-angle control.
• • Extended Service Life: Premium materials and heat treatment reduce replacement frequency and operating costs.
• • High Impact Strength: Resist cracking and deformation under heavy impact loads.
• • Universal Compatibility: Fit major crusher brands (including Hazemag, Sandvik, Metso, Kleemann, Terex) and custom models.
• • Cost-Effective: Competitive pricing with reliable quality; reduce maintenance time and downtime.

Applications

Widely used in:

• • Mining: Iron ore, copper ore, gold ore, quartz, and hard rock crushing.
• • Quarrying & Aggregates: Limestone, granite, basalt, sandstone, and gravel production.
• • Cement Industry: Clinker and raw material crushing.
• • Recycling: Concrete, asphalt, demolition waste, and glass recycling.
• • Construction & Road Building: Crushed stone for highways, railways, and concrete structures.

Installation & Maintenance Tips

• • Regular Inspection: Check for wear, cracks, or deformation every 200–500 operating hours.
• • Timely Replacement: Replace when wear reduces thickness by 30% or when cracks appear to avoid housing damage.
• • Torque Specification: Follow manufacturer torque values for mounting bolts to prevent loosening.
• • Compatibility Check: Verify plate model and dimensions match your crusher’s apron and housing before installation.
