Every enquiry we receive comes down to one question: what do you have to break? So the range is organised into two solutions — hard rock above roughly 150 MPa, and soft rock or construction waste below it. Each has its own flow, its own wear logic and its own reference projects running in China today.
Granite, basalt, diabase, river stone — 100–300 MPa, high silica, and the wear bill that comes with it.
A jaw takes the first hit, a cone does the reduction work and takes back the oversize, and a screen sizes the output into saleable fractions. On abrasive rock this costs less per ton than any impact-based line, however the machines are priced.
Limestone, dolomite, sandstone, coal gangue and demolition concrete — softer feed where one impactor replaces the primary and secondary crushing stages.
The impact chamber tolerates rebar, asphalt and wet sticky lumps that would stall a cone, and it gives a cubical product in a single pass — which is why most C&D yards and limestone quarries run an impactor rather than a cone.
Four material situations cover most enquiries. Find yours, read the flow and the reason — then open the solution page for the machines and the reference projects.
| Your material | Recommended flow | Why |
|---|---|---|
| Granite, basalt, diabase, river stone | Jaw → Cone → Screen Hard rock solution › |
High silica eats impact parts. A cone takes the reduction work at a fraction of the wear cost per ton, even though its price per machine is higher. |
| Limestone, sandstone, demolition concrete | Impact → Screen Soft rock solution › |
One impactor replaces two crushing stages and tolerates rebar and asphalt that would stall a cone — the shortest flow, the smallest yard. |
| Manufactured sand, cubical aggregate spec | Jaw → Cone → VSI VSI plants › |
When the contract specifies flakiness limits, a VSI re-shapes the fraction that cones leave needle-shaped — 0–5 mm included. |
| Topsoil, coal, sand, soil-rock separation | Heavy-duty screen only Screening plants › |
No crushing duty means a screening plant works standalone — and scalping off clay and fines first is what keeps the crusher downstream from blinding. |
Between two flows? Three facts settle it: rock, maximum lump and target tonnes per hour. We answer with a configuration, not a brochure. Talk to an engineer ›
Most of these cost buyers more in the first year than the price difference between the right and wrong machine. All of them come from enquiries we have quoted.
Rock type, maximum lump size, target output per hour and the destination port are enough for a first recommendation — including the cases where a single machine beats a three-stage line on total cost.
