Drawing and Engineering Review
We review mating surfaces and interface dimensions and assess material, heat treatment and manufacturing feasibility.
Defines the discharge openings, retains oversize material and withstands further crushing loads.
Grate Bar (Grate Bar)— Hammer Crusher Wear part, position 12.
| Installation Position | Curved discharge zone below the rotor and anvil; position 12 in the layout and internal exploded view. |
| Main Function | Defines the discharge openings, retains oversize material and withstands further crushing loads. |
| Replacement Frequency | Very high replacement frequency; replace as a set if grate openings enlarge, bars bend or break, ends wear, or product size exceeds the specified limit. |
| Item | Details |
|---|---|
| Material Options | High-manganese steel, wear-resistant alloy cast steel, or a high-manganese substrate with alloy inserts or hardfacing |
| Typical Properties and Acceptance Criteria | Grate bars experience impact, compression, gouging and frictional wear. High-manganese steel suits duty with enough impact for work-hardening. Hardfacing and insert options require verification of bonding, orientation, thermal cracking and spalling risk. In addition to composition and hardness, control curvature, cross-section, end supports, spacing, thermal expansion and height variation across the set: grate openings directly govern the upper product size. |
| Principal Failure Mechanism | Impact, cutting and abrasive wear; enlarged openings, blockage, erosion and fatigue |
