Buy a sand screw washer for rutile 25 tph in Sierra Leone

For rutile (TiO₂) mining operations in Sierra Leone – particularly in the southern and southwestern regions including the Moyamba and Bonthe districts – a 25 tph sand screw washer is essential to upgrade heavy mineral concentrate by removing clay, silt, and light impurities. Rutile has a high specific gravity (4.2‑4.3) and is often recovered from alluvial deposits that contain fine sand, clay, and organic debris. A sand screw washer gently separates the heavy rutile particles from lighter waste using water and gravity, producing a cleaner, higher‑grade product for export to pigment and titanium metal industries. When you buy a sand screw washer for rutile 25 tph in Sierra Leone, you need a corrosion‑resistant, efficient machine that handles abrasive slurry with low maintenance. OCP Mechanical Company, a factory‑direct manufacturer with over 40 years of experience, supplies Type W‑25 sand screw washers with polyurethane wear parts and water recycling options, backed by 24/7 online support.

Why a sand screw washer is a practical choice for rutile

Rutile is often mined from heavy mineral sands that also contain ilmenite, zircon, and quartz. A sand screw washer uses a single‑shaft screw (800‑1,000 mm diameter, 5‑6 m trough) to gently agitate and lift the heavy mineral while allowing lighter clay, silt, and organic matter to overflow. Polyurethane wear shoes are standard – they resist abrasion from sharp rutile particles and prevent iron contamination. Many Sierra Leone rutile operations have successfully used Type W‑25 washers, reporting improved concentrate grades (typically 85‑92% TiO₂) and reduced slime losses. An adjustable weir allows precise control of the overflow cut size, ensuring you retain valuable fine rutile while discarding only ultrafine gangue.

Key features that lower your cost per ton of rutile

When you buy a sand screw washer for rutile 25 tph in Sierra Leone, focus on features that directly affect recovery and operating expenses:

• Polyurethane wear shoes – Last 3‑5 times longer than steel shoes in abrasive rutile sand and prevent metal contamination.

• Adjustable weir – Allows fine‑tuning of the overflow cut size (typically 0.075‑0.15 mm), balancing impurity removal against rutile recovery.

• Variable frequency drive (VFD) – Adjust screw speed from 15‑25 rpm; slower speed reduces turbulence and preserves coarse rutile grains.

• Heavy‑duty gearbox (15‑22 kW) – Sealed bearings prevent contamination from fine sand dust.

• Water recycling system (optional) – A settling pond or hydrocyclone can reuse 80‑90% of process water – a valuable advantage in areas with seasonal water scarcity.

• Stainless steel shaft (optional) – For highly corrosive slurry (e.g., seawater used in processing), stainless steel prevents rust.

Operational tips for rutile washing in Sierra Leone

Sierra Leone’s tropical climate means heavy rainfall during the wet season. To maintain efficiency, adjust the weir height to prevent overflow of clean rutile fines. For feed containing high clay, add a desliming screen (0.5‑1.0 mm) ahead of the screw washer. Inspect polyurethane shoes every 200 hours; replace when thickness is reduced by 50%. Clean the water injection nozzles weekly to prevent clogging with fines. Keep a spare set of polyurethane shoes and bearings on site. After washing, test the concentrate grade using a simple table or pan – aim for >90% TiO₂.
