Description
The Palmer PSL
Sand Lifter is a small, dilute phase pneumatic
transporter with capacities of 3 or 6 tons per
hour (rated on silica sand). It can be fed by
bulk bag, mobile transfer hopper, or fixed
position silos. The system is used primarily
for small sand feed operations (e.g.-feeding a
5 ton silo over a 200 #/minute mixer from bulk
sacs).
Simplicity and
low cost make this unit attractive as compared
to bucket elevators, screw augers, and the
like. The system runs in both automatic and
manual transport modes.
Specially
designed elbows divert the transported sand
from under the transporter to the vertical and
horizontal supply lines of the sand supply
hopper. The connecting pipe between the lower
elbow and the elbow that will be fitted to the
top of the main sand hopper to be supplied by
the customer.
Transporting is
automatic as long as the level of sand feeding
the transporter inlet is maintained. A low
material proximity switch located in the
transporter inlet will shut down operation of
the unit if there is insufficient sand to
blow. If there is no sand feeding the unit,
operation will cease until sand is supplied.
The sand level
of the hopper receiving material from the PSL
is maintained by a high level indicator system
(supplied with the PSL). The proximity type
indicator will operate on a “keep full”
basis. In other words, whenever the sensor is
clear of sand, the transporter will blow. This
ensures that the receiving bin is always full
and does not force the transporter to keep up
in a just in time situation.
All electrical
and pneumatic controls required to operate
this system are supplied. All items pictured
on the left are included in the standard
unit.
