Works with the sealing system to exclude dust from the gear and plain bearing lubrication areas.
Dust collar (Dust Collar)— Gyratory Crusher Wear part, position 25.
| Installation Position | At the bottom shell dust exclusion interface; position 24 in the FLS section diagram annotated on this website. |
| Main Function | Works with the sealing system to exclude dust from the gear and plain bearing lubrication areas. |
| Replacement Frequency | Moderate wear exposure; consider replacement for excessive clearance, wear grooves, deformation, rubbing or dust ingress. |
| Item | Details |
|---|---|
| Material Options | OEM-specified cast steel, ductile iron, copper alloy or wear-resistant composite |
| Typical Properties and Acceptance Criteria | Material selection depends on whether the design uses a contact seal, labyrinth or air seal; the part name alone is insufficient. Control roundness, concentricity, sealing clearance, surface roughness, wear resistance and dimensional stability. Inspect the collar together with the dust seal, bottom shell and eccentric assembly. |
| Principal Failure Mechanism | Abrasion, fatigue, corrosion or assembly damage; use photographs of failed parts from the site to identify the dominant mechanism |
