As the secondary crushing equipment on crushing ore materials, cone crusher with the features of high crushing ratio,large output, even granularity, simple structure, easy maintenance, low cost production. To maintain the efficient functioning of cone crusher is very important for the whole dressing plant stay in smooth and continuous running. As the cone crusher is always be 360 ° rotation cycle and bearing the impact workload, resulting in some failures are inevitable, as far as possible early detection and treatment, to avoid dragging into a serious malfunction.

1.  Mobile cone rotation speed more quickly than 10r/min. Reasons: Gap between principle axis and small copper sleeve is too small, friction increases; Running interrupt or oil clean is not clean; Small copper sleeve fragmented, bad lubrication condition. Solutions and suggestions: Enlarge the gap until reach appropriate value; Check oil quality or change; Inspect or replace broken.

2. Crushing capacity descend. Reasons: Feeding material has higher water content; Feeding material size is too large; Liner excessive wear, crushing ratio decreased; Feeding distribution is uneven; Feeding material contains too much to clay. Solutions and suggestions: Water content should be less than 5%; Reduce feeding material size. Replace liner; Adjust feeding condition and strengthen screening.

3. Fixed liner is loosened. Reasons: U-bolts are not tightened; Filler is broken; Liner is fractured; contact surface between adjustment ring and liner wear and tear. Solutions and suggestions: Tighten U-bolts; Replace lining board; Repair wear face to standard values.
