How to Select Vibrating Screen for Gold Ore 100 tph
For gold ore processing in Ghana and South Africa, a vibrating screen is not just a sizing device – it directly impacts crusher efficiency and downstream recovery. Knowing how to select vibrating screen for gold ore 100 tph helps you avoid blinding, reduce recirculating loads, and improve mill feed consistency. Gold ore can vary from dry, free‑milling quartz to wet, clay‑bearing material. Below we explain the key selection criteria and how OCP Mechanical Company supplies Type S vibrating screens tailored to West and Southern African gold conditions.
1. Determine the Required Cut Size and Number of Decks
The first step in how to select vibrating screen for gold ore 100 tph is defining the product size. For a typical 100 tph gold plant after a jaw crusher, the screen usually separates at 10‑20 mm – oversize returns to the cone crusher, and undersize feeds the ball mill or heap leach pad. A single‑deck screen is sufficient if only one separation is needed. A double‑deck screen allows you to produce two fractions (e.g., 0‑5 mm tailings and 5‑15 mm mill feed) or to scalp out fine dust before secondary crushing. For most 100 tph gold operations, a single‑deck screen of 1,500 x 4,500 mm or 1,800 x 5,000 mm is a practical choice.

Many gold mines in Ghana’s Ashanti belt use a 10 mm cut size to balance ball mill feed quality and crusher recirculation.
2. Choose Screen Media for Gold Ore Conditions
Screen media selection is a critical part of how to select vibrating screen for gold ore 100 tph. For dry, abrasive quartz ore, woven wire (spring steel or stainless) is economical and provides sharp separation. However, if the ore is sticky due to clay or moisture (>5‑6%), polyurethane panels with tapered openings resist blinding and last 3‑5 times longer. For gold ore with moderate moisture, rubber media can also work well. All price and life data are for reference only; contact our team for current recommendations.
Producers in South Africa’s Witwatersrand region often use polyurethane panels on fine decks (0‑10 mm) and woven wire on coarse decks to balance cost and performance.
3. Consider Screen Size, Stroke, and Slope
To optimize how to select vibrating screen for gold ore 100 tph, match the screen size to the crusher’s output. For a 100 tph cone crusher (closed circuit), the screen should be sized to handle 150‑200 tph (including recirculating load). A screen of 1,800 x 5,000 mm with a stroke of 6‑10 mm and a slope of 18‑22° is a proven combination for gold ore. A finer stroke (6‑8 mm) reduces wear on screen panels when screening abrasive quartz; a coarser stroke (10‑12 mm) helps break sticky material. Use a variable frequency drive (VFD) to adjust screen speed on the fly.
OCP’s Type S screen offers adjustable stroke and slope, allowing you to fine‑tune for specific gold ore characteristics.
4. Plan for Durability and Maintenance
Gold ore can be abrasive, especially when it contains quartz. When selecting a screen, look for:
Heavy‑duty exciter with oversized bearings.
Modular screen panels for quick replacement.
Dust covers to protect moving parts.
Easy access to screen media for cleaning and replacement.
Proper screen selection can reduce recirculating load by 15‑25% and increase overall plant throughput without adding a new crusher.
