Factory direct sand washing machine for salt 68 tph in Namibia

For salt processing in Namibia – with major solar salt operations at the coastal pans near Walvis Bay and Swakopmund – a 68 tph sand washing machine is essential for upgrading raw salt to high‑purity industrial or food‑grade product. Raw salt contains clay, silt, and insoluble residues that must be removed. A factory direct sand washing machine for salt 68 tph in Namibia offers a corrosion‑resistant, efficient solution that reduces costs and improves product quality. OCP Mechanical Company, a direct manufacturer with over 40 years of experience, supplies Type W‑68 sand washers with marine‑grade materials, backed by 24/7 online support.

Why a screw washer is a practical choice for salt

Salt is moderately abrasive and highly corrosive. A sand screw washer gently agitates salt crystals while allowing clay and insoluble fines to overflow. When you choose a factory direct sand washing machine for salt 68 tph in Namibia, the Type W-68 uses a single‑shaft screw (1,200‑1,500 mm diameter, 7‑8 m trough) with polyurethane wear shoes – they resist corrosion and prevent metal contamination. The adjustable weir controls the overflow cut size, balancing impurity removal against salt recovery. Many Namibian salt processors have successfully used screw washers to upgrade raw salt from 95‑97% NaCl to over 99% pure.

Corrosion‑resistant features for salt processing

Salt is highly corrosive to carbon steel. A factory direct sand washing machine for salt 68 tph in Namibia must include:

• Stainless steel shaft and screw flights – 316L stainless steel is widely recommended for salt applications.

• Polyurethane wear shoes – Resistant to saltwater and last 3‑5 times longer than steel shoes.

• Sealed gearbox – Prevents salt dust ingress. Use synthetic oil.

• Marine‑grade paint – Epoxy coating on all external carbon steel parts (trough, frame).

• Stainless steel water nozzles and fasteners – Prevents clogging and rust.

These features add 20‑30% to the cost compared to a standard sand washer, but they extend equipment life from 2‑3 years to 10‑15 years in saline environments.

A factory direct sand washing machine for salt 68 tph in Namibia with stainless steel shaft and polyurethane shoes ex‑works ranges from $25,000to$45,000 USD. Shipping to Walvis Bay port (CIF) adds $5,000‑$10,000. A starter set of polyurethane shoes, stainless steel nozzles, and seals adds $1,500‑$2,500. Total landed cost is approximately $32,000‑$58,000 USD.

How to optimize salt washing and reduce water use

Salt washing requires careful water management. Use fresh water (not seawater) for the final rinse to avoid re‑dissolving salt. Maintain a water‑to‑salt ratio of 1.5‑2:1. Install a water recycling system (settling pond or thickener) to reuse 80‑90% of process water – critical in arid Namibia. Adjust the weir so that only impurities overflow; salt crystals should settle and be lifted. Test product purity every shift using a simple conductivity meter. If purity drops, increase water flow or reduce feed rate. For food‑grade salt, a second freshwater rinse section is recommended.

Operational tips for salt washing in Namibia

Namibia’s coastal climate is humid, which can cause salt to absorb moisture and become sticky. Use a heated screen or air knife on the dewatering screen to keep product free‑flowing. Rinse the washer with fresh water at the end of each shift to prevent salt crystallization on the screw. Inspect stainless steel components monthly for pitting corrosion – early detection prevents failure. Keep a spare set of polyurethane shoes and stainless steel nozzles on site.
