Lvlon makes hydraulic cone crushing equipment in Henan, China. The CH single-cylinder series is the value-hydraulic option between the manual spring cone crushers and the fully automated multi-cylinder HP series. Eight models. Integrated spindle-and-mantle design-no bowl bearing, no spherical seat. Factory-direct pricing. OEM on motor power, voltage, cavity type and hydraulic configuration.
One Cylinder That Replaces a Ring of Them
A multi-cylinder hydraulic cone crusher clamps the bowl assembly with eight to sixteen hydraulic cylinders arranged around the upper frame. Tramp iron forces the bowl upward against the cylinders. The relief valves open. The bowl lifts. The obstruction passes. The cylinders re-clamp. The system works precisely. It also requires eight to sixteen cylinders, multiple accumulators, a manifold of hydraulic lines and a level of maintenance attention that a simpler system does not.
The CH uses one large cylinder at the bottom. The cylinder piston supports the entire main shaft and mantle assembly. During normal crushing, the cylinder holds the shaft at a set height-the CSS. To change the CSS, the operator adjusts the cylinder's extension. The shaft moves up or down. The gap between mantle and concave changes. The product size changes. To release tramp iron, the relief valve opens. The cylinder retracts. The shaft and mantle drop. The obstruction falls through the widened discharge. The cylinder re-extends. The shaft returns to its set position.
The hydraulic circuit is simpler than the multi-cylinder version-one cylinder, one accumulator, one relief valve, fewer hoses, fewer fittings, fewer leak points. The trade-off is that the crushing force is not distributed as evenly as with a ring of cylinders around the bowl. For moderate to hard rock at moderate throughput, the single cylinder provides enough force. For the hardest ores at the highest throughputs, the multi-cylinder HP applies more uniform crushing pressure.
The difference in maintenance complexity is real. A multi-cylinder system with a leaking hose on cylinder number seven out of twelve means tracing the leak through a network of lines. The single-cylinder system with a leaking hose has only one circuit to inspect. Simpler hydraulics means fewer failure modes and faster diagnosis.
The Spindle and Mantle Are One Piece
In a spring cone crusher and in a multi-cylinder HP crusher, the mantle is a separate component that mounts onto a tapered spindle. Between the mantle bore and the spindle sits a bowl bearing and a spherical seat. These are precise-machined interfaces that wear over time. When the bowl bearing wears, the mantle wobbles. The crushing gap becomes uneven. Product quality degrades. Bearing replacement is a major maintenance task.
The CH spindle is machined with an integral taper. The mantle liner slides directly onto the spindle taper-no intermediate bearing, no spherical seat, no alignment adjustment between two separate parts. The entire rotating assembly is roughly 30–40% fewer components than a separate spindle-and-mantle design. Fewer components means fewer wear surfaces and fewer assembly tolerances to manage.
Changing the mantle still requires lifting the entire shaft assembly out of the crusher. The assembly is heavier than lifting a mantle alone on a spring crusher-the shaft comes out with it. But the reassembly requires no bowl bearing alignment and no spherical seat gap adjustment. The total liner change time is comparable.
CH vs CHS: Standard Feed vs Primary Feed
The CH models cover standard secondary and tertiary cavity profiles-five to six cavity types per model, feed openings from 42 to 321 millimeters. The CHS models are the extra-coarse variants-two cavity types per model, feed openings from 223 to 622 millimeters.
A CHS660 accepting feed up to 622 millimeters encroaches on jaw crusher territory. A mine that blasts to a controlled top size of roughly 600 millimeters can feed directly into a CHS660-no jaw crusher. One machine replaces a jaw-plus-cone pair. The CHS is not a universal primary crusher-it still relies on the material feeding at a controlled maximum size. Oversize blast rock that exceeds the feed opening still needs a jaw or a grizzly to scalp it. But within its feed limits, the CHS eliminates a crushing stage.

FAQ
Q: Single-cylinder (CH) or multi-cylinder (HP)-which one?
CH: simpler hydraulics, fewer components, lower purchase price-roughly 1.2–1.4× spring crusher price vs HP's 1.4–1.7×. HP: more uniform crushing force, finer control, higher maximum throughput. Medium-scale operation on a budget that wants hydraulic automation: CH. Large-scale continuous operation where throughput capacity is the priority: HP.
Q: Can the CHS really replace a jaw crusher?
With blast rock controlled to a maximum size within the CHS feed limit and rock hardness at moderate levels-yes. If blast oversize exceeds 30% of the feed, a jaw crusher or grizzly is still needed ahead of the CHS.
Q: Is the integrated spindle harder to service?
Liner change time is comparable. The shaft assembly lifts out as one piece-heavier than a mantle-only lift, but reassembly requires no bowl bearing alignment. The total job time is similar.
