In this example, two issues
were immediately recognized. As material left the
rock box at the end of the first conveyor, a portion
of it missed the spoon and never made it onto the
belt. Additonally, the material on the belt was loaded
off-center.
A simple change to the design of the rock
box eliminated spillage and improved the off-center
loading.
This example demonstrates two belt conveyors
feeding into a transfer chute that combines the two
materials into one flow. Some spilling is occuring,
but for the most part, this design is working at this
flow rate.
The issue with this example speaks for itself.
While the issue might be obvious, the cause may not
be. Is the flow rate too high? Is the exit of the chute
too close to the receiving conveyor? Is the receiving
conveyor moving too slowly?
Using Bulk Flow Analyst™ these questions can be
answered without physically testing the system.
As material flows, the forces applied to the components
channelling the flow also change. In the example shown
below, the effect of friction and the shifting load
within the dump body could significantly alter weight
distribution on the vehicle.
Using BFA™ the forces (displayed as color spectra
on the dump body surfaces) can be extracted and plotted,
enabling the user to determine whether the truck's front
tires would leave the ground at any time while dumping.
In the following example, the smaller particles have
cohesive properties applied to them. Notice the tendency
to stick to each other and the walls of the chute. The
significance of these effects are nearly impossible
to predict using traditional methods.
The following example was created
to demonstrate the amount of scatter of particles
as they leave a spinning broadcaster. There are
two animations back-to-back. The first shows the
spinnerin the second one, the "road" has been
turned off and
velocity
vectors
are displayed. Striations in the pattern are clearly
visible.
In the following example, the data
being sought was the force necessary to push the
flight bar conveyor into the pile of material at
a given rate and burden depth.
