Drawing and Engineering Review
We review mating surfaces and interface dimensions and assess material, heat treatment and manufacturing feasibility.
Supports the back of the blow bar, maintains its correct installed position and spreads impact loads into the rotor.
Blow Bar Support Strip (Blow Bar Backing Bar)— Impact Crusher Wear part, position 03.
| Installation Position | Between the back of the blow bar and the rotor seat, position 03 in common layout A/B. |
| Main Function | Supports the back of the blow bar, maintains its correct installed position and spreads impact loads into the rotor. |
| Replacement Frequency | Medium replacement frequency; inspect when replacing blow bars and replace for depressed support faces, cracks, excessive clearance or deformation. |
| Item | Details |
|---|---|
| Material Options | Quenched and tempered alloy steel, high-strength cast steel or OEM-specified support material |
| Typical Properties and Acceptance Criteria | Backing bars require adequate compressive strength, core toughness, fretting resistance and dimensional stability. Inspect blow bar seat contact area, flatness, wear grooves, cracks and permanent deformation. Match material hardness to the blow bar and rotor seat to avoid concentrating loads on narrow edges or around holes. |
| Principal Failure Mechanism | Impact, cutting and abrasive wear; sliding and three-body abrasion, local impact and cracking around fastener holes |
