What Is the Ideal CSS for Gold Ore Cone Crusher 100 tph
For gold mining operations in Ghana and South Africa, setting the correct closed side setting (CSS) on a cone crusher is a key factor in balancing crushing efficiency, liner wear, and downstream grinding costs. The question what is the ideal CSS for gold ore cone crusher 100 tph depends on ore hardness, feed size, and the desired product for ball mill feed or heap leaching. While there is no single number that fits every gold ore, a well‑proven range helps operators achieve consistent results. Below we discuss typical CSS values and how OCP Mechanical Company supports African gold mines with reliable Type C cone crushers.
Typical CSS Range for a 100 tph Gold Ore Cone Crusher
When asking what is the ideal CSS for gold ore cone crusher 100 tph, the answer varies with the crushing stage. For secondary crushing (after a jaw crusher), a CSS of 12‑18 mm is widely used. This produces a product with a P80 of 20‑30 mm, suitable for feeding a ball mill or a tertiary crusher. For tertiary or fine crushing (e.g., preparing feed for a ball mill or a heap leach pad), a tighter CSS of 6‑12 mm is common, yielding a P80 of 8‑16 mm.
OCP’s Type C cone crusher (short head cavity) is designed for such applications. Note: Product data are constantly updated; for the latest specifications, please contact our online customer service.
Many gold mines in Ghana’s Ashanti Belt and South Africa’s Witwatersrand region operate their 100 tph cone crushers at a CSS of 10‑14 mm, achieving a good balance between liner life and downstream mill throughput.
Factors That Influence the Ideal CSS
Determining what is the ideal CSS for gold ore cone crusher 100 tph for your specific ore requires considering three main factors:
Ore hardness (Bond work index) – Harder ore (e.g., 18‑22 kWh/t) benefits from a wider CSS (14‑18 mm) to avoid overloading the crusher. Softer ore (10‑15 kWh/t) allows a tighter setting (8‑12 mm) for finer product.
Feed size distribution – If the feed contains many fines below the CSS, a tighter setting may cause packing. Pre‑screening fines before the cone crusher allows you to run a smaller CSS without issues.
Downstream equipment – For a ball mill, a finer product (smaller CSS) reduces grinding energy but increases crusher wear. The optimal CSS is often where the combined crushing + grinding cost is minimized. Many operators find this balance at a CSS of 10‑14 mm.
OCP’s technical team can perform a simple cost analysis to help you find what is the ideal CSS for gold ore cone crusher 100 tph for your circuit. We recommend starting with a CSS of 12 mm, then adjusting based on power draw and liner wear.

How to Maintain the Optimal CSS
Once you determine what is the ideal CSS for gold ore cone crusher 100 tph, maintaining it is essential. As liners wear, the effective CSS increases. For every 100 hours of operation, a cone crusher’s CSS may open by 1‑2 mm. Re‑adjust the setting every 200‑300 hours to keep product size consistent. OCP’s Type C cone crusher features a hydraulic threaded bowl assembly, making CSS adjustments safe and quick.
To keep your operating costs low, we recommend:
Measuring CSS weekly using lead balls or a laser tool.
Keeping a log of CSS, crusher power draw, and product size.
Adjusting CSS in 2‑3 mm increments and observing changes in recirculating load.
Many mines in Ghana and South Africa have reduced product size variation by 50% after implementing weekly CSS checks.
