The Button That Replaces the Crowbar
A spring cone crusher stalls. The operator shuts down the motor. Waits 30 minutes for the machine to cool. Opens the inspection door. Climbs in with a crowbar and starts prying jammed rock out of the crushing chamber piece by piece. The job takes an hour or more. During that hour the conveyor is stopped. The screens are stopped. The secondary crusher behind it is stopped. The entire circuit is idle.
The HP crusher stalls. The operator presses the hydraulic cavity-clearing button on the control panel. The hydraulic cylinders push the bowl assembly upward. The discharge opening at the bottom of the chamber widens to several times its normal setting. The jammed material falls through under its own weight. The cylinders retract. The bowl returns to its set position. The operator restarts the motor. Elapsed time: a few minutes.
The same button-press logic applies to tramp iron. A loader tooth enters the crushing chamber. The pressure inside the hydraulic cylinders spikes. The relief valve opens in milliseconds. The cylinders release. The bowl lifts. The obstruction passes. The hydraulic system re-pressurizes the cylinders. The bowl returns to its exact previous position. The CSS has not changed. The operator may not even notice it happened.
The same logic applies to CSS adjustment. A spring crusher requires stopping the machine, loosening the adjustment ring lock, rotating the ring manually to raise or lower the bowl, measuring the gap, re-locking and restarting-half an hour of downtime. The HP crusher adjusts the CSS from the control panel. Press and hold the adjustment button until the digital readout shows the target setting. Done. No stopping. No climbing. No measuring with feeler gauges.
The control system monitors oil temperature, oil pressure, motor current, eccentric speed and liner wear. All values display on a screen in the control room. Alarms trigger at preset thresholds. Trend data logs for maintenance planning. The operator knows the condition of every crusher in the circuit without leaving the control room.
Five Cavities: Two More Than a Spring Cone Crusher
A spring cone crusher offers three cavity types-standard, medium and short head. The HP series offers five-extra coarse, coarse, medium, fine and extra fine. The extra coarse cavity has the widest feed opening of any cone crusher cavity type. On the HP800, the extra coarse cavity accepts feed up to 350 millimeters-approaching jaw crusher feed capability. This allows the HP to serve as a secondary crusher receiving directly from a primary jaw without an intermediate crushing stage.
The extra fine cavity has the narrowest feed opening and the longest parallel zone. On the HP100, the extra fine cavity delivers a minimum closed-side setting of 6 millimeters-approaching sand-maker territory. Material entering the extra fine cavity undergoes extended grinding in the choke zone and exits at a fineness that substantially reduces the load on the downstream sand-making or ball-milling stage.
Between extra coarse and extra fine, the coarse, medium and fine cavities provide the same coverage as the three spring cone crusher cavities. The five-cavity system means the HP series covers applications from near-primary to near-tertiary in a single machine platform. A quarry that switches between aggregate production and manufactured sand production changes cavity types on the same HP crusher rather than adding a separate tertiary crusher.

FAQ
Q: HP hydraulic or spring cone crusher-which one?
HP if your operation runs continuously and downtime costs more than the price difference. The hydraulic CSS, tramp release and cavity clearing save hours of downtime per incident. Spring if the budget is the primary constraint, the mine runs a single shift and tramp iron is rare. The crushing principle is identical. The difference is automation and downtime cost.
Q: What is the price difference between HP and a spring cone crusher of the same size?
Roughly 40–70% more for HP. The premium buys hydraulic automation and intelligent monitoring. If tramp iron events and cavity stalls happen regularly, the saved downtime recovers the premium within six to twelve months. If they are rare, the spring crusher is the more economical choice.
Q: Which cavity type for my application?
Extra coarse: largest feed, near-primary duty. Coarse: standard secondary crushing. Medium: intermediate. Fine: fine secondary or tertiary. Extra fine: smallest feed size, near-sand-making fineness. Send us your feed size and product target.
