You specify the equipment long before anyone buys it. We give you the data, the method and the calculations to specify a hydraulic cone crusher — and to defend the choice in a feasibility study.
In most mining projects the crushing circuit is fixed during the feasibility or pre-feasibility study — by the engineering firm, not the mine. Getting onto a design house vendor list means being specified years before a purchase order exists. That happens on technical merit, not on price. So this page is written for the engineer, not the buyer.
Single-cylinder hydraulic cone crusher selection based on the Whiten (1972) steady-state model and the Bond (1952) energy relationship. Every output carries assumptions, sources and open items — it is built to be checked, not trusted.
A 19-function open-source plugin covering selection, plant configuration, product-size simulation, circulating load, cost estimation and a 14-section proposal skeleton. Run it on your own duty and audit the numbers.
NH series (9 models) and NS high-speed series (4 models): cavity options, closed-side setting ranges, maximum feed size, installed power, weight and outline dimensions.
Multi-stage crushing plus screening with closed-circuit population-balance iteration: per-stage P80, circulating load and mass balance. Useful for trade-off studies.
Machine documentation for your technical specification. Tell us which standard and which project stage and we will supply what is required.
A direct technical contact for project-specific questions — not a general sales inbox.

| 1. Send the duty | Ore type, feed size distribution, target product and capacity. If you have a flowsheet in mind, send it. |
|---|---|
| 2. We return a documented selection | Stage count, cavity, CSS, unit count and power — with the assumptions and the simulated product curve. |
| 3. You audit it | Run the same duty through the public tool. The calculation is reproducible; that is the point. |
| 4. Vendor listing | If the equipment suits the project, we will complete your vendor pre-qualification documentation. |
Yes, and we encourage it. The simulation is based on published models — Whiten (1972) for the steady-state size distribution and Bond (1952) for specific energy — implemented independently with no proprietary third-party data. The plugin is open source under the MIT licence.
Yes. Cavity options, CSS ranges, maximum feed size, installed power, weight and outline dimensions for the NH series (9 models) and NS high-speed series (4 models). Tell us the project stage and required format.
We do not invent them. Unknown fields return null, and literature defaults are explicitly labelled as literature rather than measured. Conflicting sources are presented side by side. For a feasibility study you should calibrate against measured plant data — we provide the calibration workflow.
We are working to be. Send us your pre-qualification package requirements and we will complete them.
From several hundred tonnes per hour in aggregates up to 1,500 t/h and above in metal mines, across the NH and NS ranges.
