Cone crushers are created to granulate hard i medium hard materials as, for example, basalt, granite, metal ores, diabase, quartz, limestone, sandstone, cement clinker. Those materials cannot contain more than 5% silty clay loam pollution and cannot contain humidity higher than 10%. These crushers are used to produce materials for road constructions, railway embankments and also for primary materials granulating which will be processed at another machines, for example at mills. Cone crushers have hydraulic support of internal crushing cone. Exhaust port is hydraulically regulated and controlled at the control desk. Hydraulic protection system before overload which causes automatic withdrawal of internal cone and his return to primary position after overload relief.
