1. Must operate with choke‑fed feeding: The optimal working condition for a cone crusher is full material covering the feed distributor. Choke feeding delivers full laminar crushing performance. Insufficient feed results in poor product shape and accelerated liner wear.
2. Keep iron objects out of the crushing chamber: Though overload protection is fitted, frequent tramp‑iron entry will still damage main shafts and liners.
3. Lubrication is critical: Malfunction of the thin‑oil lubrication system can burn out the bowl‑shaped bearing directly and cause prolonged downtime.
4. Chamber‑profile selection: Coarse chambers accept large feed lumps for secondary crushing; fine chambers produce small‑sized output for fine crushing. The same machine can switch chamber profiles by replacing liners.
5. Do not set the discharge opening below the minimum permissible gap. Forcing an overly narrow gap leads to equipment overload and damage.
Brief Comparison with Other Crushers
1. Vs. jaw crusher: Jaw crushers perform primary coarse crushing. Cone crushers handle secondary and fine crushing, delivering far higher throughput for ores of equal hardness.
2. Vs. impact crusher: Impact crushers rely on impact force and produce good aggregate shape. However, their liners wear rapidly when processing extremely hard rock. Cone crushers suit hard rock yet produce slightly more flaky and elongated particles.
