selection guidelines Ž next generation conveyor lambda chain the following procedure is useful for economical and quick conveyor chain selection step 1 confirm the operating conditions of the conveyor step 2 tentatively select the chain size step 3 calculate the design chain tension step 4 verify the chain selection step 5 verify the allowable roller load step 3 calculate the chain tension next the chain tension should be calculated using the actual weight of the conveyor chain and material conveyed as shown below 1 chain rolling step 1 confirm the operating conditions of the conveyor the following information is needed to design a chain conveyor a type of conveyor slat conveyor bucket conveyor etc b method of chain travel horizontal inclined vertical c type weight and size of conveyed materials d weight of materials to be transported per foot of conveyor length e conveyor speed f conveyor length g considerations for special environments step 2 tentatively select chain size to tentatively select the chain size estimate the chain tension t by the following formula a chain with an allowable load equal to or greater than the above calculated chain tension may be tentatively selected selection guidelines conveyor lambdaŽ t lbs mt ˇ f ˇ k1 1 where mt total weight of material conveyed lbs f coefficient of friction sliding and/or rolling f1 and f2 of tables i and ii see page 23 k1 chain speed coefficient table iii see page 24 22
