The line that turns wet crystal into bagged product: centrifuge dewatering, drying, screening, conditioning and packing — engineered as one train downstream of your evaporative crystallizer, sized from 10 t/d pilots to 1,000 t/d plants.
Reference ranges from published salt-plant and dryer data on NaCl and inorganic salt systems.
One continuous train: dewater, dry, screen, condition, pack — with mother liquor and dust loops closed back into the system.
Crystallizer discharge → Pusher / peeler centrifuge (3–5% cake moisture) → Fluid bed / flash / rotary dryer → Multi-deck vibrating screen → Conditioning (iodine / anti-caking) → Silo → Bagging (1–50 kg / 1 t)
Mother liquor returns to the crystallizer; dryer exhaust passes a cyclone / dust collector; oversize recirculates through a crusher — nothing leaves the line except packed product and clean air.
A complete salt line runs 20–26 major equipment items; what is core and what is optional depends on feed and product grade.
Aggregated from published supplier data on salt, crystal and slurry drying equipment — indicative ranges for preliminary sizing, not a process guarantee.
Ranges aggregate published specifications from multiple equipment suppliers (salt line contractors, centrifuge and dryer manufacturers, ZLD system builders); figures are indicative for screening and must be verified against your feed, crystal size distribution and utility set.
The dryer is the energy center of the line — pick it by crystal size, heat sensitivity and tonnage, not by catalog.
Temperature and residence figures follow published dryer data for the listed duties; final selection needs your crystal breakage test and heat-sensitivity data.
Published salt-plant layouts scale the same process train across three installation-area classes.
Anonymized configurations reconstructed from published supplier project data.
Engineering guides on dryer and centrifuge selection, salt refining and ZLD-end drying.
This line starts where crystallization ends — see the trains that feed it.
This page aggregates published supplier specifications and project data (salt plant contractors, centrifuge and dryer manufacturers, ZLD system builders) into an engineering screening view. All names are withheld; configurations are described generically. Figures are indicative ranges for preliminary line sizing — final selection requires your feed analysis, crystal size distribution, moisture targets and site utilities.
Recurring questions from engineers specifying the downstream line.
On salt and crystal lines, almost always. Mechanical dewatering to 3–5% cake moisture (2–2.5% optimized) in a pusher or peeler centrifuge removes water at a fraction of the thermal cost of drying — skipping it substantially raises the dryer’s evaporation duty and fuel bill.
Washed inorganic salt at 3–30 t/h is standard vibrating-fluid-bed territory. Flash dryers suit heat-sensitive organic crystals (0.5–3 s residence, no discoloration); rotary and tube-bundle dryers carry high tonnage with indirect steam heat and low attrition — tube-bundle units reach 1,600 m² of heat area.
≤0.3–0.8% residual moisture is the published range for fluid-bed / rotary salt lines; refined washing plants report 0.3–0.5%. For ZLD mixed-salt residues, disc-film dryers reach ≤1% — handleable, landfill-free solids.
Yes — 304/316L polished contact surfaces with GMP executions, iodine / anti-caking dosing, metal detection and magnetic separation. Peeler centrifuges ship in cGMP wall-through execution with nitrogen blanketing and CIP.
Published lines bag from 150 g retail sachets through 1–50 kg industrial bags to 1-tonne bulk bags, fed from a common screening-and-silo section with PLC interlocks and remote diagnostics.
Washing runs with saturated brine in countercurrent so the brine dissolves no additional NaCl; published lines hold total NaCl loss under 10% across washing, centrifuging, drying and screening.
