Single-Cylinder vs Multi-Cylinder Cone Crusher: 6 Ways

Quick answer

Both are hydraulic cone crushers and both crush by lamination, but they put the hydraulics in different places. A single-cylinder cone crusher uses one cylinder beneath the main shaft to adjust and protect the machine; a multi-cylinder cone crusher uses several cylinders around the frame to clamp and release it, with the setting adjusted separately. That one structural difference drives six practical consequences — adjustment, protection, cavity choice, product shape, maintenance and cost. This guide works through each, and ends with which type suits which job.

What they have in common

Before the differences, the shared ground, because it is the foundation of the choice:

Both are secondary or tertiary machines, not primary crushers
Both use lamination crushing, squeezing rock against rock
Both produce a cubical product with low flake content
Both are hydraulically protected and hydraulically adjusted
Both are available across a wide capacity range
So the question is never “is one better”. It is “which mechanism suits my duty”. The two types have different strengths, and a good supplier will recommend the one that fits, not the one that is easier to sell.

Difference 1: Where the hydraulic system sits

This is the root difference, and everything else follows from it.

Single-cylinder (CH series) — one hydraulic cylinder sits beneath the main shaft and supports it vertically. The whole hydraulic function — adjustment, protection and clearing — is handled by that one cylinder. Fewer components, a simpler hydraulic circuit and a more compact machine.

Multi-cylinder (HP series) — several hydraulic cylinders are arranged around the frame. Their main job is to clamp the upper frame to the lower frame, and to release that clamp when protection is needed. Adjustment is done by a separate mechanism that rotates the bowl.

The consequence: a single-cylinder machine has a simpler hydraulic system, and a multi-cylinder machine has a structure built specifically for hard duty clamping under heavy load.

(The two photos below show the difference at a glance: the CH machine carries its cylinder under the shaft; the HP machine carries its cylinders around the frame.)

Difference 2: How the discharge setting is adjusted

Single-cylinder: the main shaft is raised or lowered by the cylinder, which changes the closed-side setting directly.

Multi-cylinder: the bowl is rotated by a hydraulic motor and gear, which raises or lowers the bowl and changes the setting.

Both allow adjustment while the machine is running, and both allow automation. In practice the single-cylinder arrangement gives a wide adjustment range with fewer moving parts; the multi-cylinder arrangement gives very precise control of the setting, which matters when the product size is tight.

Difference 3: Overload protection and tramp iron release

Both types protect the machine from uncrushable material, but by different means.

Single-cylinder: when an uncrushable enters the chamber, the cylinder releases and the main shaft drops, passing the object. The system then resets. Clearing is done by lowering the shaft, which is a simple, single action.

Multi-cylinder: when overload occurs, the cylinders release the clamping force, the upper frame lifts and the object passes. The frame then reseats. The release is fast and the machine returns to production quickly.

Both protect the machine. The multi-cylinder design’s lifting frame makes it particularly effective at passing large tramp metal under heavy load, which is one reason it dominates hard-rock secondary duty.

Difference 4: Cavity options and flexibility

The multi-cylinder design is known for its wide range of cavity configurations — coarse, medium, fine and short-head variants within the same frame size. That flexibility lets one machine be fitted to different duties by changing the cavity, which is valuable where the feed or the product requirement may change.

The single-cylinder design offers a more focused set of cavities, optimised around its intended duty. It is not less capable; it is less configurable, which in a stable application is no disadvantage at all.

Cavity options at a glance:

Single-cylinder (CH): a focused cavity set optimised for its duty — standard coarse / medium / fine
Multi-cylinder (HP): a wider cavity set within the same frame — coarse / medium / fine / short-head
Rule of thumb: if your feed and product mix may change over the plant’s life, the broader cavity range of the multi-cylinder machine is worth considering. If your duty is fixed and well understood, the single-cylinder machine is simpler and entirely sufficient.

Difference 5: Product shape and capacity behaviour

Because both crush by lamination, both produce good cubical shape. The differences are in the details:

The multi-cylinder machine is typically chosen for hard, abrasive rock at high reduction ratios, where its clamping structure and cavity range give it an edge.
The single-cylinder machine is typically strong on medium-hard material and on applications with a high fines requirement.
Our own published ranges, for reference:

HP series (multi-cylinder) — cavity diameter 900-1500 mm, capacity 60-480 t/h, power 90-400 kW (models HP100 to HP500).

CH series (single-cylinder) — cavity diameter 900-1750 mm, capacity 60-700 t/h, power 132-450 kW (models CH420 to CH870).

Read the tables together with your duty, not in isolation. A larger number is not automatically the better choice.

Difference 6: Maintenance, cost and automation

Maintenance — single-cylinder: fewer hydraulic components and a simpler circuit, so fewer points to service. The cylinder and its seals are the main items. Multi-cylinder: more hydraulic components, but each is accessible; the frame clamping system is robust and long-lived.

Cost — both are hydraulic cone crushers and both are priced on their size and build. Neither is inherently cheaper; the duty and the cavity determine the model, and the model determines the cost.

Automation — both are fully automatable. The single-cylinder design offers multiple operating modes — manual, automatic load control and automatic discharge control — with a high level of integration. The multi-cylinder design offers automatic setting control that holds the product size as the liners wear.

On either type, ask the supplier what the control system reports and how the setting is held as the liners wear. That question separates a modern machine from an old one.

Which one should you choose?

Choose multi-cylinder (HP series) when:

The rock is hard and abrasive (granite, basalt, river pebble)
You need a wide range of product settings
The duty is heavy and continuous, at high reduction ratios
Your feed or product mix may change over time
Choose single-cylinder (CH series) when:

The material is medium-hard
You need high fines output or a specific fine product
You value a simpler hydraulic system and simpler maintenance
The duty is fixed and well understood
In many plants both appear in the same flowsheet: a multi-cylinder machine for the hard secondary duty and a single-cylinder machine for fine tertiary work. The two are complementary, not rivals.

A real plant example

Our Indonesia 300 t/h basalt project pairs a PEV jaw crusher with an HP300 multi-cylinder cone crusher and a VSI900 sand maker, producing 0-5, 5-10, 10-20 and 20-31.5 mm cubic aggregate from basalt at Mohs 6-7. Hard, abrasive rock went to the multi-cylinder machine — the choice the material made, not the supplier.

Frequently asked questions

Q: Which produces better particle shape?
A: Both crush by lamination, so both produce good cubical shape. In hard, abrasive rock at high reduction, the multi-cylinder machine is the more common choice.

Q: Is single-cylinder simpler to maintain?
A: Yes, generally. It has fewer hydraulic components and a simpler circuit, which means fewer service points.

Q: Can a single-cylinder crusher handle hard rock?
A: It can, but for hard, abrasive rock at heavy duty, the multi-cylinder machine is the more common and often the more economical choice.

Q: Does the type affect the price much?
A: Price follows size and build. The right question is which type suits your material and duty — then the model, then the price.

Q: How do I know which one my project needs?
A: Send your material and hardness, maximum feed size, required product sizes and target capacity. We will recommend the type, the model and the cavity.
