Secondary and Tertiary Crushing for Hard Rock
LIPU multi-cylinder hydraulic cone crushers are designed for secondary and tertiary crushing of hard and medium-hard rock in mining, quarrying, and aggregate production.
The HP series combines hydraulic adjustment, overload protection, multiple crushing cavity options, and laminated crushing to support stable continuous operation and controlled product sizing.
Different models and cavity configurations can be selected according to feed size, required capacity, final product size, material hardness, and the complete crushing circuit.
A multi-cylinder hydraulic cone crusher is a compression crusher mainly used for secondary and tertiary crushing.
Material enters the crushing chamber between the mantle and concave. As the eccentric assembly rotates, the moving cone continuously approaches and moves away from the fixed crushing surface.
The material is repeatedly compressed and crushed until it becomes small enough to pass through the discharge opening.
Compared with traditional spring cone crushers, multi-cylinder hydraulic cone crushers use hydraulic systems for functions such as discharge adjustment, overload protection, and cavity clearing.
They are commonly selected for hard-rock applications requiring high capacity, stable operation, and multiple final aggregate sizes.
LIPU HP series multi-cylinder hydraulic cone crushers are available with different crushing cavities to match different feed sizes and discharge requirements.
Coarse cavity configurations such as C1, C2, and C3 are mainly used when larger feed sizes and coarser discharge products are required.
Typical applications include:
The exact cavity should be selected according to the upstream crusher discharge and required downstream product size.
Fine cavity configurations such as F1, F2, and F3 are designed for smaller feed sizes and finer discharge requirements.
Typical applications include:
A finer cavity does not automatically mean higher output. Capacity depends on feed size, discharge setting, material characteristics, and operating conditions.
Multi-cylinder hydraulic cone crushers are suitable for hard and medium-hard ores and rocks.
Typical materials include:
Typical applications include:
For hard-rock crushing, the multi-cylinder hydraulic cone crusher is commonly installed after a Jaw Crusher.
For projects requiring another cone crusher structure, LIPU also provides single-cylinder and Simmons cone crusher options for different operating requirements.
The motor drives the transmission shaft through the belt and pulley system.
The transmission shaft then drives the eccentric assembly through the gear system, causing the moving cone to perform an eccentric crushing motion around the main shaft.
Material entering the crushing chamber is repeatedly compressed between the mantle and concave.
During continuous operation:
The final product size is mainly affected by:
Stable and reasonably continuous feeding is important for achieving consistent cone crusher performance.
A typical multi-cylinder hydraulic cone crusher includes:
The mantle and concave are the main wear parts in direct contact with the material.
The hydraulic system assists with discharge adjustment, overload protection, and cavity clearing.
A multi-cylinder hydraulic cone crusher is commonly selected when the project requires hard-rock secondary or tertiary crushing with controlled product sizing.
It is particularly suitable when:
For medium-hard materials where impact crushing and product shaping are more important, an Impact Crusher may be another option.
The final crusher selection should consider both crushing performance and long-term wear cost.
A multi-cylinder hydraulic cone crusher normally works as part of a complete crushing and screening plant.
A typical hard-rock process can be arranged as:
Vibrating Feeder → Jaw Crusher → Multi-Cylinder Hydraulic Cone Crusher → Vibrating Screen → Finished Aggregate
For higher reduction or finer products:
Jaw Crusher → Secondary Cone Crusher → Fine Cone Crusher → Vibrating Screen
In a closed circuit:
Cone Crusher → Vibrating Screen → Oversized Material Return → Cone Crusher
A Belt Conveyor is normally used to transfer material between the crushing and screening stages.
The final plant configuration depends on:

Actual processing capacity may vary according to material hardness, feed gradation, moisture, cavity type, closed-side setting, and operating conditions.
The technical parameters should therefore be used for preliminary model and cavity selection.
Crusher selection should consider the complete crushing circuit rather than only the nominal capacity.
For preliminary selection, please provide:
Important selection factors include:
Feed Size
The maximum feed size should match both the selected model and cavity.
Crushing Stage
Coarse cavities are generally more suitable for secondary crushing, while fine cavities are more commonly used for tertiary or fine crushing.
Final Product Size
The required product size affects cavity selection and discharge setting.
Required Capacity
Capacity should be considered together with feed gradation, cavity filling, and discharge setting.
Material Abrasiveness
Highly abrasive materials increase mantle and concave wear and should be considered when evaluating operating cost.
Closed-Circuit Load
Returned oversized material from the vibrating screen increases the actual crusher load and should be included in plant design.
LIPU Heavy Industry provides crushing, screening, grinding, classification, and mineral processing equipment for mining and aggregate projects.
For multi-cylinder hydraulic cone crusher applications, LIPU can assist with:
For complete crushing projects, the cone crusher can be selected as part of the full plant rather than as an isolated machine.
