Dead loads correspond to the self-weight of the apron feeder and any other hardware such as skirts, hoppers and chutes that may tie into the feeder frame. Live loads link to the dynamic loads caused by the material shear and torque being transmitted from the drive system (while operating and at the start up).
As stated above in the first segment, bulk density of the ore/rock is one of the basic criteria requirements that should be included for proper apron feeder sizing. Density is the weight of material in a given volume, and usually bulk density is measured as tons/cubic meter (t/m³) or …

Apron feeders are volumetric-type feeders, which means bulk density is used to determine the speed and power needed to extract a certain tonnage per hour of the material. The minimum bulk density is used to determine the speed, and the maximum bulk density establishes the power (torque) needed for the feeder.
Roller Chain Conveyors or Apron Chain Conveyors are used to transfer heavy bulk materials from one point to another. This manual for practical application indicates the …
