Mining Chain and Attachments

Round-link mining chain, conveyor flight chain, and the attachment hardware (pushers, scrapers, side-plates) used in underground haulage, surface bucket conveyors, and mineral processing.

Mining Chain and Attachments — page 1 of the Dibblee Industries catalog (W.J. Keating, 1940–)
Page 176 — original catalog

Mining chain is engineered for impact and abrasion service inherent to bulk-material handling. Round-link sections are heat-treated for toughness; conveyor flight chain is supplied with matched cross-flights, side-plates, and attachment hardware for retrofit on existing flight conveyors. Service environments include coal, potash, salt, gold, and aggregate operations.

Product types

  • Heat-treated round-link mining chain
  • Conveyor flight chain with matched cross-flights
  • Side-plates, pushers, scrapers
  • Replacement attachment hardware

Typical applications

  • Underground haulage
  • Surface conveyor systems
  • Mineral processing plants
  • Bulk-material handling

Double inboard strand assemblies can be made up at the factory, or in the
field. Other assemblies may be engineered to suit individual situations.
However, since careful and precise matching is required, factory
assembly and repair is recommended.
Example: 12 sections of twin inboard assemblies 26 x 92mm, assembly
length 22. 5m. Grade C quality. Flight bar spacing at 1104mm.
