Spring Cone Crusher for Secondary and Tertiary Crushing
LIPU Simmons cone crushers are designed for secondary and tertiary crushing of medium-hard and hard rocks and ores in mining, quarrying, and aggregate production.
The CS series uses a mature spring cone crusher structure with compression crushing, mechanical transmission, spring overload protection, and adjustable crushing cavities. Coarse, medium-coarse, and fine cavity configurations can be selected according to feed size, required product size, capacity, and the overall crushing circuit.
A Simmons cone crusher is a compression-type cone crusher commonly used for medium and fine crushing after primary crushing.
Material enters the annular crushing chamber between the mantle and concave. The eccentric mechanism causes the moving cone to continuously approach and move away from the fixed crushing surface.
During this movement, material is repeatedly compressed, bent, and crushed until it becomes small enough to pass through the discharge opening.
Compared with newer hydraulic cone crusher designs, the Simmons cone crusher uses a traditional spring protection system and a mechanically mature crushing structure.
It is widely used in:
LIPU CS series Simmons cone crushers are available with different cavity configurations to match different feed sizes and final product requirements.
The current series includes:
The coarse cavity is designed for larger feed sizes and is generally used for secondary crushing.
It is suitable for:
For example, the CS1400C-D accepts feed sizes up to 235 mm.
The medium-coarse cavity provides a balance between feed size and final product size.
It is suitable for:
CS1400Z-D and CS1400Z-X are medium-coarse cavity configurations with different stroke and discharge ranges.
The fine cavity is used where smaller product sizes are required.
It is suitable for:
Fine cavity models include CS1400S-X and CS1200S-X.
The correct cavity should be selected according to feed size, discharge size, required capacity, material characteristics, and circulating load.
Simmons cone crushers are suitable for medium-hard and hard rocks and ores.
Typical materials include:
Typical applications include:
In a typical hard-rock plant, the Simmons cone crusher is installed after a Jaw Crusher for further size reduction.
The motor transfers power through the drive system to the transmission shaft.
The transmission shaft drives the eccentric sleeve through the bevel gear system.
As the eccentric sleeve rotates, the moving cone performs a gyratory crushing motion.
During operation:
The crushing process is continuous as long as material is supplied steadily.
Crushing performance is affected by:
A typical Simmons cone crusher includes:
The mantle and concave are the main wear parts in direct contact with the crushed material.
Wear-part selection should therefore consider material hardness, abrasiveness, feed gradation, and operating conditions.
The spring protection system is one of the main structural features of the Simmons cone crusher.
During normal crushing, the support sleeve is held in position by spring pressure.
If uncrushable material such as metal enters the crushing chamber, the spring system can compress and temporarily enlarge the discharge opening.
This allows the foreign material to pass through and helps protect the crusher from mechanical damage.
After the foreign material is discharged, the spring system returns the crusher to its normal operating position.
The discharge opening can be adjusted according to the required product size.
The crusher also uses a cavity clearing system to assist when material becomes trapped inside the crushing chamber.
A Simmons cone crusher normally operates as part of a complete crushing and screening plant.
A typical hard-rock process is:
Vibrating Feeder → Jaw Crusher → Simmons Cone Crusher → Vibrating Screen → Finished Aggregate
For projects requiring two cone crushing stages:
Jaw Crusher → Secondary Cone Crusher → Fine Cone Crusher → Vibrating Screen
In a closed circuit:
Cone Crusher → Vibrating Screen → Oversized Material Return → Cone Crusher
The vibrating screen separates qualified material from oversized particles.
Oversized material can be returned to the crusher for additional crushing.
A Belt Conveyor is normally used to transfer material between the different crushing and screening stages.
LIPU CS series Simmons cone crushers are available in coarse, medium-coarse, and fine cavity configurations.
| Model | Cavity Type | Stroke (mm) | Max. Feeding Size (mm) | Discharge Opening (mm) | Capacity (t/h) | Motor Power (kW) | Weight (t) |
|---|---|---|---|---|---|---|---|
| CS1400C-D | Coarse | 30 | 235 | 30–60 | 210–530 | 220 | 25 |
| CS1400Z-D | Medium Coarse | 30 | 215 | 25–50 | 200–500 | 220 | 25 |
| CS1400Z-X | Medium Coarse | 25 | 180 | 22–45 | 180–475 | 220 | 25 |

Actual capacity may vary according to material hardness, feed gradation, abrasiveness, moisture, cavity configuration, discharge setting, and operating conditions.
Technical parameters should therefore be used for preliminary model selection.
Simmons cone crusher selection should be based on the complete crushing circuit rather than only nominal capacity.
For preliminary model selection, provide:
Important selection factors include:
Feed Size
The cavity must accept the maximum particle size discharged from the upstream crusher.
Required Product Size
Coarse cavities are generally used for larger feed and secondary crushing, while fine cavities are more suitable for tertiary crushing.
Required Capacity
Capacity varies according to model, cavity type, stroke, discharge setting, and feed conditions.
Material Abrasiveness
Highly abrasive materials increase mantle and concave wear and should be considered when estimating operating cost.
Closed-Circuit Load
Returned oversized material from the vibrating screen increases the actual crusher throughput requirement.
For projects requiring newer hydraulic adjustment and protection systems, a Single-Cylinder Cone Crusher or Multi-Cylinder Hydraulic Cone Crusher can also be evaluated according to the actual crushing duty.
LIPU Heavy Industry provides crushing, screening, grinding, and mineral processing equipment for mining, quarrying, and aggregate projects.
For Simmons cone crusher applications, LIPU can assist with:
For complete crushing plants, the cone crusher can be selected together with feeding, primary crushing, screening, and conveying equipment according to actual project conditions.
What is a Simmons cone crusher used for?
A Simmons cone crusher is mainly used for secondary and tertiary crushing of medium-hard and hard rocks and ores in mining, quarrying, and aggregate production.
What is the difference between coarse and fine cavities?
Coarse cavities accept larger feed sizes and are mainly used for secondary crushing. Fine cavities accept smaller feed and are used when a finer final product is required.
What materials can a Simmons cone crusher process?
Typical materials include granite, basalt, quartzite, gabbro, river pebble, iron ore, gold ore, copper ore, and other medium-hard to hard materials.
How does the spring protection system work?
When uncrushable material enters the chamber, the spring system can compress and temporarily enlarge the discharge opening, allowing the foreign material to pass through.
Can LIPU provide a complete crushing plant?
Yes. LIPU can configure feeding, jaw crushing, cone crushing, screening, conveying, and closed-circuit return systems according to project requirements.
We provide a variety of mining and processing equipment, including feeders, rock crushers, grinders, classifying and screening machines, washing machines, gravity separators, flotation machines, magnetic separators, electric separators, dewatering equipment and laboratory mineral processing equipment.
