Information and illustrations of cone crushers, links to other resources including used cone crushers and plant design considerations

The following illustrations show side views of the internal workings of Symons and Telsmith cone crushers. The drawings also show a side view of the inside of both shorthead (Telsmith uses the term "finehead") and standard cone crushers.
Additional illustrations of the inside of a cone crusher can be viewed here, and here. For much more information on cone crushers, including of the Symons, Telsmith, Kue Ken, and Allis Chalmers cone crushers, please go to our CONE CRUSHER INFORMATION page.

standard type
allows a larger feed rock and the pinch point length is shorter than on the shorthead type. This allows a more evenly distributed discharge gradation.

The shorthead type has a more limited feed opening and the pinch point length is much longer resulting in a higher percentage of fines being produced.

The Symons shorthead cone crushers include the 3SH, 4SH, 4 1/4SH, 5 1/2SH, and 7SH. The Symons standard cone crushers include the 3S, 4S, 4 1/4S, 5 1/2S, and 7S.

Other manufacturers such as Telsmith call their shorthead type a "fine cone", or FC for short. The Telsmith fine cone crushers include the 36FC, 48FC, and 66FC. The Telsmith standard cone crushers include the 36S, 48S, and 66S. Telsmith also makes a 389S and 489S which are standard cone crushers that allow a larger size of feed rock.

The Allis Chalmers Hydrocone series of crushers used different styles of manganese liners to change from standard to shorthead or fine crushing. This allows the plant operator to keep the same basic cone and adapt it to his individual needs.

The Allis Chalmers cone crusher was the first to use hydraulic adjustment and relief. To see a side view of the inside of a Allis Chalmers cone crusher please go here. Allis Chalmers became Allis Minerals, then purchased by Svedala, and now is owned and supported by Metso Minerals.
