Sand Screw Washer Price for Sea Sand Desalination

For sand producers in Indonesia and Vietnam, sea sand is abundant but must be desalinated to remove salt and chloride before use in concrete. A sand screw washer for sea sand desalination is an efficient solution to wash away salt and fine impurities. Understanding the sand screw washer price for sea sand desalination helps you invest in equipment that turns low‑value sea sand into a high‑quality, specification‑compliant construction material. OCP Mechanical Company supplies factory‑direct Type W screw washers with freshwater injection systems, designed for corrosive environments, with local support and 24/7 online assistance.

Why a Screw Washer Is a Practical Choice for Sea Sand Desalination

Sea sand contains salt crystals that must be reduced below 0.01‑0.05% for concrete use (e.g., SNI 03-1970-1990 in Indonesia, TCVN 7570 in Vietnam). A sand screw washer for sea sand desalination floods the sand with freshwater while the screw agitates, liberating salt and fine clay. Multiple passes or a freshwater rinse section can achieve the required chloride level. Polyurethane wear shoes resist corrosion from saltwater, and the gearbox is sealed to prevent salt ingress. The washer typically includes a freshwater manifold with adjustable spray bars. Many sea sand processors in West Java and the Mekong Delta have adopted this method, producing chloride‑free sand for local construction.

Price Range and Factors Affecting Cost

The sand screw washer price for sea sand desalination depends on capacity, number of freshwater rinse stages, and materials of construction. OCP’s factory‑direct pricing (ex‑works) for a 50‑80 tph single‑shaft screw washer (Type W‑80) with freshwater rinse kit ranges from $20,000to$35,000 USD.

Many sea sand processors in Vietnam have recovered their investment within 6‑12 months by selling desalinated sand at a premium over untreated sea sand.

How to Optimize Desalination Efficiency

To get the most value from your sand screw washer price for sea sand desalination, follow these practices:

• Use multiple rinse stages – A single screw washer with a long trough and multiple water injection points can achieve chloride levels <0.01%. For stricter requirements, two washers in series or a separate rinse section.

• Monitor freshwater flow – Maintain a water-to-sand ratio of 1.5‑2:1. Too little water leaves salt; too much wastes water. Install flow meters and pressure regulators.

• Inspect for corrosion – Salt accelerates corrosion of steel. Use polyurethane wear shoes and coated or stainless steel hardware in contact with saltwater.

• Test product regularly – Take sand samples every shift to measure chloride content. Adjust rinse water flow or retention time as needed.

OCP’s Type W screw washer can be supplied with a stainless steel shaft, polyurethane flights, and protective coatings for long service life in sea sand applications.
