※KA and AA Series are stronger (double the tensile strength) versions of KG, AG, and AM Series.
Features of each series
-
・Intake/feed conveyor KG/KA Series
Intake/feed conveyors is a first line for collected waste conveyance. Often subject to heavy loads, depending on the waste.
Heavy conveyed loads and impacts cause an apron to buckle, which promotes heavy wear between rollers and bushes, while dust and so on attaches to a chain and causes poor roller rotation.
KG/KA Series focus on providing good bush - roller wear resistance and resistance against poor roller rotation.
-
・Bottom ash conveyor (Dry) AG/AA Series
Conveys ash cooled by water after incineration. As this equipment conveys ash that has had some of its water content removed, the ash may stick to the chain itself depending on conveyance conditions.
As this ash sticks to the chain, it causes articulation and roller rotation problems.
AG/AA Series focuses on providing good chain articulation and resistance against poor roller rotation.
-
・Bottom ash conveyor (Wet) AM/AP Series
Directly conveys incinerator ash as it falls into water to be cooled, so majority of a conveyor is underwater.
AM/AP Series focuses on added corrosion resistance to AG/AA Series.
-
・Fly ash conveyor (Normal) FG Series
Conveys fly ash from a incinerator or boiler.
Fly ash may stick to a chain itself, causing articulation and roller rotation problems.
FG Series focuses on resistance against articulation and roller rotation problems.
-
・Fly ash conveyor (Corrosive) FP Series
Slaked lime is often added to fly ash conveyors before a bag filter to cool down, which may create a corrosive environment for a chain.
FP Series focuses on added corrosion resistance for (general) fly ash conveyors.
-
・Slag conveyor YP Series
Used on conveyors carrying slag from a melting furnace. Water granulated slag turns sand-like and gets into chain clearances, causing severe bush and roller wear.
Part of a chain also passes through water.
Slag turns water highly alkaline or acidic, which can severely corrode the chain as well.
YP Series focuses on providing wear and corrosion resistance.

※Maximum allowable load is a value calculated based on Tsubaki in-house standards and is calculated strength. As long as there are no other constraints, maximum allowable load is used in selecting large size conveyor chain.
This value will differ by manufacturer and is not a guaranteed value.
※Contact a Tsubaki representative regarding average tensile strength.
