Factory direct sand washing machine for sea sand 85 tph in Indonesia

For sand producers in Indonesia’s coastal regions – from Java to Sumatra and Kalimantan – sea sand is an abundant resource, but it requires desalination and fines removal before use in concrete, block making, or plaster. A factory direct sand washing machine for sea sand 85 tph in Indonesia offers a cost‑effective, corrosion‑resistant solution to turn raw sea sand into specification‑grade construction material. OCP Mechanical Company, a direct manufacturer with over 40 years of experience, supplies Type W‑85 sand screw washers engineered for saltwater applications, backed by local support and 24/7 online assistance.

Why a sand screw washer is essential for sea sand desalination

Sea sand contains salt (sodium chloride) that must be reduced below 0.01‑0.05% for concrete use. Freshwater washing is the widely used method, and a screw washer floods the sand while agitating to liberate salt and clay. A factory direct sand washing machine for sea sand 85 tph in Indonesia uses a single‑shaft screw (1,200‑1,500 mm diameter, 8‑9 m trough) with a freshwater injection manifold. Polyurethane wear shoes resist saltwater corrosion and prevent iron contamination. Many Indonesian sand processors in the Riau Islands, Bangka Belitung, and North Sumatra have adopted this technology, producing chloride‑free sand that meets SNI standards.

Key features that lower your operating cost and ensure corrosion resistance

When you invest in a factory direct sand washing machine for sea sand 85 tph in Indonesia, focus on features that directly affect durability and cost per ton. The Type W-85 includes a stainless steel shaft and freshwater spray bars with corrosion‑resistant nozzles – essential for marine environments. Polyurethane wear shoes are standard; they resist saltwater attack and last 3‑5 times longer than steel shoes. A heavy‑duty gearbox (30‑45 kW) with sealed bearings prevents salt ingress. An adjustable weir allows precise control of overflow, balancing salt removal against sand recovery. For stricter chloride limits, a dual‑stage freshwater rinse section can be added.

Compared to other suppliers, OCP’s factory‑direct model saves 15‑20% on both the washer and genuine wear parts. A Type W-85 screw washer ex‑works typically ranges from $22,000to$38,000 USD. Shipping to Jakarta or Surabaya (CIF) adds $4,000‑$8,000.

How to maximize desalination efficiency and reduce water consumption

A factory direct sand washing machine for sea sand 85 tph in Indonesia can achieve chloride levels below 0.01% with proper operation. Maintain a water‑to‑sand ratio of 1.5‑2:1 – too little water leaves salt, too much wastes fresh water. Install a water recycling system (settling pond or thickener) to reuse 80‑90% of process water, a valuable advantage in areas with limited fresh water. Pre‑screen the feed to remove shells, coral fragments, and debris larger than 10 mm. This reduces wear on the screw and improves washing efficiency. Test the product chloride content every shift and adjust freshwater flow accordingly.

Many Indonesian sand plants have reduced fresh water consumption by 80% after adding a settling pond, saving both cost and environmental impact.

Maintenance tips for sea sand washing in tropical marine environments

Saltwater accelerates corrosion, so routine maintenance is essential. Rinse the machine with fresh water at the end of each shift, especially the shaft seals and spray nozzles. Inspect polyurethane wear shoes every 200 hours; replace when thickness is reduced by 50%. Check the gearbox oil for water contamination monthly – saltwater ingress degrades lubricant quickly. Use a marine‑grade grease for bearings. Keep a spare set of wear shoes, seals, and stainless steel nozzles on site to avoid downtime.
