If these conditions continue to occur, a time-delayed shutdown of the crusher may occur. {{image3-a:l-w:250}}The cone crusher may be equipped with either an air/oil cooler or a water cooler to help dissipate heat from the lube oil. The air/oil cooler will require periodic cleaning of the cooling fins to remove debris or build-up of dust and dirt.

A cone crusher can crush a variety of rocks, from medium to hard. The way a cone crusher operates is similar to how a gyratory crusher does, but in a cone crusher the slope in the breaking space is not as steep. Although it is known for its ability to crush hard and abrasive ores and rocks, the cone crusher is better suited for secondary crushing.
