type of crusher hammer

There are several types of crusher hammers used in hammer crushers, impact crushers, and other crushing equipment. The type of hammer selected depends on the material being crushed, wear resistance requirements, and the crushing mechanism. Here are the main types:

1. Common Hammer Types Based on Shape & Structure
– Forged Hammers – Made from high-carbon steel or alloy steel, forged for high strength and durability. Used in heavy-duty applications.
– Cast Hammers – Made from high-chromium cast iron (e.g., Cr20, Cr26) or manganese steel for wear resistance. Common in cement and mining industries.
– High Manganese Steel Hammers – Excellent toughness and work-hardening properties, ideal for hard materials like granite.
– High Chromium Alloy Hammers – Extremely wear-resistant but more brittle; used for abrasive materials like limestone.
– Bimetal Composite Hammers – Combine a tough core (for impact resistance) with a hard outer layer (for wear resistance).

2. Hammer Types Based on Fixation Method
– Swing Hammers (Hanging Type) – Freely suspended on a rotor, swinging outward when rotating (common in hammer mills).
– Fixed Hammers (Rigid Type) – Bolted or welded to the rotor, providing more direct impact force (used in impact crushers).

3. Specialized Hammer Designs
– Ring Hammers – Used in ring hammer crushers for coal and soft materials; shaped like rings for better crushing efficiency.
– Claw Hammers – Have claw-like protrusions for better grip on fibrous or wet materials.
– Toothed Hammers – Feature teeth or grooves to enhance material breaking efficiency.

4. Material-Specific Hammers
– Cement Industry Hammers – Made of high-chromium alloys to resist abrasion from clinker.
– Mining & Quarry Hammers – Often use manganese steel or bimetal designs for hard rocks.
– Recycling Crusher Hammers – Reinforced to handle metal scraps, concrete, and demolition waste.

Key Factors in Hammer Selection:
– Material hardness & abrasiveness
– Required impact vs. grinding action
– Maintenance frequency & replacement cost
