Chain Components

Chain conveyors are essential to many bulk handling systems that handle such materials as powders, grains, flakes and pellets. Quality components are obviously important to longevity and high-production levels.

All Rubber TMH offers 4Bs component selection for two types of chain conveyors using drop forged chains.

En-Masse Chain Conveyors

Mainly used in agricultural applications, the flight height can be as low as 12.5% of the material being transported. Material is fed into the conveyor from the top and falls through the moving chain to the bottom of the box. Because the particles interlock, the material moves as a single stream at the same speed as the chain. This highly efficient conveying process allows nearly the entire conveyor cross section to move as bulk.

Drag Chain Conveyors

Mainly used in industrial applications, the material height being transported is often less than or equal to the flight height (can be more, depending on the application). Drag conveying will literally “pull” the material along. Speeds are often much slower than en-masse conveying.

The components on offer fall into the following five categories:

  • Forged Chains

4B's drop forged chain is made of special heat treated high grade alloy steel, case hardened to Rockwell C57-62 with a ductile core hardness of Rockwell C40. A superior heat treatment technique provides the optimum forged chain link with a more resilient ductile core for shock resistance, and an extremely hard exterior surface for premium wear resistance.

4B forged chain links and pins are also available in all grades of stainless steel.

  • Bolt ‘n Go Chains

An assembly system for forged and round link chains using bolt-on flights rather than welded.

  • Sugar Industry Chains

4B’s sugar chain range satisfies all Sugar Mill chain requirements throughout the process. Engineered in a range of constructions, including welded steel chains, engineered steel chains, steel bush chains, forged fork link chains, bagasse chains and more:

    • Wash and Feed Table Chains
    • Main and Auxiliary Cane Carrier Chains
    • Shredded Cane Carrier Chains
    • Intermediate Carrier Chains
    • Cush Cush/Bagacilio Elevator Chains
    • Pressure Feeder Roller Drive Chains
    • Diffuser Chains
    • Bagasse Elevator, Conveyor & Reclaim Chains
    • Bagasse to Boiler Leveller Chains
    • Dry and Wet Sugar Elevator Chains
  • Sprockets and Trailers

4B sprockets and trailers are manufactured from high-grade heat-treated steel to a minimum hardness of 57 HRC. Each piece is machined to size with appropriate bore and keyway specific to client requirements.

  • Round Link and Miscellaneous Chains

There is a further assortment of options available. Please discuss with your All Rubber TMH specialist to ascertain you’re investing in the best choice of chain components for your system.
