GB/T 24186 NM Series Wear Plates: Core Applications & Industry-Specific Solutions

Product Details

1. Construction Machinery: Durability for Heavy-Duty Equipment

Construction equipment operates in abrasive environments (rock, soil, concrete), demanding materials that resist wear on high-stress components:

Key Applications: Excavator buckets, loader buckets, dump truck bodies, bulldozer blades, and grader moldboards.
Grade Selection:
- NM400/NM450: Light-to-medium duty (residential construction, road building) – dump truck bodies, small excavator buckets.
- NM500/NM550: Heavy-duty (mining, demolition) – large excavator bucket teeth, bulldozer blades.
- NM600: Ultra-heavy duty (quarry rock handling) – crusher attachments, high-impact bucket liners.
User Benefit: Extends equipment service life by 3–5x vs. standard steel; reduces maintenance frequency and replacement costs. For example, a mining company using NM500 for excavator buckets reported 60% less downtime vs. mild steel.

2. Thermal Power & Coal Yards: Abrasion Resistance for Energy Infrastructure

Thermal power plants and coal handling facilities face relentless wear from coal, ash, and slag – NM series plates are the industry standard for critical components:

Key Applications: Coal mill liners, coal chutes, ash conveyors, boiler hoppers, and coal storage silo liners.
Grade Selection:
- NM450/NM500: Coal chutes and conveyor liners (medium wear from coal particles).
- NM500/NM550: Coal mill liners (severe abrasion + impact from grinding media).
- NM550/NM600: Ash handling systems (abrasive fly ash + high temperature).
Case Study: A 600MW thermal power plant in China replaced mild steel coal mill liners with NM500, reducing liner replacement from every 3 months to 12 months – cutting maintenance costs by 70% annually.

3. Mining & Quarrying: Withstanding Extreme Abrasion

Mining operations (coal, iron ore, limestone) involve high-impact crushing, screening, and conveying, requiring wear plates that endure aggressive mineral abrasion:

Key Applications: Crusher jaws/liners, vibrating screen decks, ore chutes, and haul truck beds.
Grade Selection:
- NM500: General mining (ore conveying, secondary crushing).
- NM550: Hard rock mining (primary crusher liners, ore hoppers).
- NM600: Ultra-hard mineral processing (tungsten ore, granite crushing) – where wear rates are 2–3x higher than coal mining.
Advantage: NM series plates maintain integrity under cyclic impact; their ductility prevents cracking, even in freezing mining environments (impact energy ≥16J at 20°C ensures toughness).

4. Port & Logistics: Bulk Material Handling

Ports and bulk terminals handle millions of tons of ores, grains, and aggregates annually – wear plates protect equipment from abrasive bulk materials:

Key Applications: Ship unloader buckets, conveyor system liners, storage hoppers, and stacker-reclaimer components.
Grade Selection:
- NM400/NM450: Grain/fertilizer handling (low-abrasion bulk goods).
- NM500/NM550: Ore/aggregate handling (high-abrasion materials like iron ore, limestone).
Value Proposition: Reduces conveyor downtime; for example, a port in Shanghai using NM500 for iron ore conveyor liners extended service life from 6 months to 24 months, improving operational efficiency.
