Roll Crusher
So what does a roll crusher do here? Specifically, it targets oversized pebbles (25mm to 150mm) that pile up in SAG and ball mill circuits. These pebbles are partially processed ore—but traditional mills can’t break them down efficiently. If left untreated, they waste energy and cut throughput.
The roller crusher uses high-pressure, low-speed compression to crush hard, abrasive pebbles. In turn, it produces a consistent, controlled product size. Unlike high-impact crushers (which make too many fines), it preserves ore value by keeping particle distribution optimal for later grinding. Additionally, operators can adjust the roller gap to meet exact feed size needs, so the recrushed material fits smoothly back into the milling circuit.
In real-world use, the roller crusher boosts circuit capacity by 10–15% in typical mineral plants. It also cuts energy use by 8–12% per unit and stabilizes workflows, thus reducing downtime from material buildup. For processors aiming to maximize ore recovery and efficiency, the roller crusher isn’t just a tool—it’s a strategic investment that drives long-term profits.
