Automated
Industrial
Salt
Washing
and
Refining
Production
Line
This
fully
automated
production
line
processes
both
sea
salt
and
rock
salt
through
complete
refining
stages
including
crushing,
washing,
centrifuge
dewatering,
and
drying.
Designed
for
both
edible
and
industrial
salt
production
applications.
Overview
The
production
line
follows
Hanpu's
proven
process
route:
raw
salt
crushing,
multi-stage
washing,
two-stage
pusher
centrifuge
dewatering,
and
hot-air
or
fluidized-bed
drying.
Downstream
processes
include
screening
and
packing.
The
system
is
engineered
for
energy
efficiency,
product
purity,
and
stable
operation.

Process
Flow
-
Pre-treatment
&
Crushing:
Reduce
raw
salt
to
suitable
particle
size,
easing
washing
and
grading.
-
Multi-stage
Washing:
Use
screw/agitator
washers
with
counter-current
rinsing
to
remove
mud,
sand
and
soluble
impurities,
improving
purity.
-
Continuous
Centrifuge
Dewatering:
Two-stage
pusher
centrifuge
lowers
moisture
and
saves
drying
energy.
-
Drying
&
Screening:
Hot-air
or
fluidized-bed
drying
to
target
moisture,
then
screening
to
grain
size
before
packing.
