Component Specifications

Definition
Crushing hammers/teeth are replaceable impact elements mounted on rotating rotors within crushers and pulverizers. They deliver kinetic energy to materials through direct impact, causing fracture and size reduction. These components are engineered for maximum impact resistance, wear life, and material-specific performance in various industrial crushing applications.
Working Principle
Operates on impact crushing principle where high-speed rotation of the rotor assembly causes hammers/teeth to strike incoming material. The kinetic energy transfer creates stress concentrations exceeding material strength, resulting in fracture and fragmentation. Impact velocity, hammer geometry, and material properties determine crushing efficiency and product size distribution.
Materials
High-chromium cast iron (HCCI), manganese steel (Hadfield steel), tungsten carbide inserts, alloy steel with surface hardening. Material selection depends on application: HCCI for abrasive materials, manganese steel for impact resistance, carbide for extreme wear applications.
Technical Parameters
  • Weight 5-50 kg
  • Hardness 500-700 HB
  • Service Life 200-2000 operating hours
  • Mounting Type Bolt-on, wedge lock, pin retention
  • Impact Toughness 15-40 J
Standards
ISO 13583, DIN 24450

Frequently Asked Questions

How often should crushing hammers be replaced?

Replacement intervals depend on material hardness, feed size, and operating conditions. Typically 200-800 hours for abrasive materials, monitored through regular wear measurement and performance evaluation.

Can hammers be reversed or rotated for extended life?

Yes, most designs allow rotation or reversal to utilize multiple wear surfaces. This practice can extend service life by 30-50% before replacement is required.

What factors affect hammer wear rate?

Primary factors include material abrasiveness, moisture content, feed size distribution, rotor speed, and hammer material composition. Proper maintenance and operating within design parameters minimize excessive wear.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
