Choosing a cone crusher comes down to five factors: the crushing stage and
cavity type, the feed size and required closed-side setting, the machine
type (single-cylinder or multi-cylinder), the throughput and power match to
your primary crusher, and the level of automation and protection you need.
Get these five right and the model selects itself. This guide walks through
each, with the data our engineers ask for first.
A cone crusher is a secondary or tertiary machine. Which cavity you need
depends on where it sits in the flowsheet:
Standard / coarse cavity Secondary crushing after a primary jaw
Accepts the largest feed, produces coarser output
Medium cavity Secondary or tertiary
Balances capacity and product size
Short-head / fine cavity Tertiary crushing
Produces the finest output and the best shape
One machine is not “better” than another here — the cavity is a choice
driven by feed size and product target. Selecting too coarse a cavity for a
fine product forces the plant to recycle more material; selecting too fine a
cavity for a coarse feed chokes the chamber.
This is the single most common source of a wrong cone crusher. Two numbers
must be respected:
Maximum feed size A cone crusher cannot accept the lumps a primary jaw
produces without a screening stage in between. The
feed must be sized to the cavity.
CSS range The closed-side setting decides the product size and
the capacity. Every model has a working range.
Our published CSS ranges, for reference:

Read the table by asking two questions: what is the largest lump that will
reach this crusher, and what product size must it produce. Those two
answers narrow the model immediately.
Both are hydraulic cone crushers, both use lamination to shape the product,
and both are built for secondary and tertiary duty. The difference is in the
mechanism and the behaviour:
Multi-cylinder (HP series)
– Hydraulic cylinders around the frame provide protection and
adjustment
– Excellent for hard, abrasive rock such as granite and basalt
– Wide range of cavity options for fine tuning
– Very stable under heavy duty
Single-cylinder (CH series)
– One hydraulic cylinder beneath the main shaft handles adjustment,
protection and clearing
– Compact, simpler hydraulic system, fewer components
– Strong on medium-hard material and on high-fines requirements
– High automation level with multiple operating modes
In practice: multi-cylinder for hard, abrasive aggregate duty and the
toughest applications; single-cylinder for medium-hard material, good
economy, and simpler maintenance. Both are in our range and we recommend
the one that fits the duty, not the one that is more profitable for us.
A cone crusher cannot fix a bottleneck it did not cause. Two checks
before selecting:
The secondary must be able to accept the primary’s output. If a
PE750×1060 produces up to 320 t/h, a secondary rated at 200 t/h will
simply be the plant’s limit.
The power draw should be consistent across stages, so no single
machine is chronically overloaded.
A common design rule is to keep the secondary capacity 10 to 20 percent
above the required finished output, so the circuit has room to run closed
and still make its numbers.
Modern cone crushers are controlled, not just operated. The factors that
matter:
Automatic overload protection that releases when tramp iron enters
Cavity clearing without manual intervention
Automatic setting control to hold product size as liners wear
A control system that reports load, power and setting
Ready availability of mantle and bowl liner wear parts
Ask, in writing, how long wear parts take to reach your country. A cone
crusher’s liner is a consumable, and a plant waiting on a liner is a plant
producing nothing.
With more than 300 EPC turnkey projects delivered, we have sized cone
crushers for hard rock quarries, manufactured sand plants and metal mines
across Southeast Asia, the Middle East, South America, Africa and Australia.
The five factors above are exactly what our engineers work through, in this
order, when we design a flowsheet.
For a real example, our Indonesia project pairs a PEV jaw crusher with
an HP300 cone crusher to produce 0-5, 5-10, 10-20 and 20-31.5 mm aggregate
from basalt at 300 t/h — a standard jaw-plus-cone flow applied to hard,
abrasive rock.
Q: How do I choose between single-cylinder and multi-cylinder?
A: Multi-cylinder for hard, abrasive rock and the toughest duty;
single-cylinder for medium-hard material, economy and simpler
maintenance. Both are hydraulic cone crushers and both are in our range.
Q: What is the maximum feed size for a cone crusher?
A: It depends on the cavity. The feed must be sized to the cavity — a cone
crusher is not a primary machine and cannot accept blasted rock directly.
Q: Can a cone crusher replace a jaw crusher?
A: Only when the feed is already small and screened. In hard rock quarries
the standard practice remains jaw first, cone second.
Q: Which cone crusher for manufactured sand?
A: Often a cone crusher followed by a VSI sand maker. The cone does the
volume reduction and the VSI improves particle shape for sand.
Q: How do I get the right model recommended?
A: Send your material and hardness, maximum feed size, required product
sizes, target capacity and destination. We will return a flowsheet with
a sizing recommendation.
Send us your material, feed size, product spec and capacity. Our engineers
will come back with a recommended model, cavity and flowsheet — usually
within 24 hours.
