Bucket Elevator
Elevator Intake
Several factors should be taken into account when planning the intake to feed material into the elevator:
1. The method and location of intake openings in the boot usually will have been determined when the
elevator was ordered. However, if the intake arrangements have or are being changed, several
factors must be considered.
a.
Inlet or Hopper Size:
The size of the inlet effects the capacity and the condition of the elevated
material. Too small an inlet means the material must be fed into the boot at excessive speed.
The excess velocity of incoming material cause damage, the buckets do not fill properly, and
material backs up in the boot, clogging the inlet.
