An ore crushing production line reduces run-of-mine material to a specified size for mineral processing, transport, or sale. A typical flow includes feeding, primary crushing, screening, and—when required—secondary or tertiary crushing with a return loop for oversize material. The right equipment depends on the ore’s properties, required capacity, feed and product sizes, and site conditions; there is no single configuration that suits every mine. In this guide, we explain how to map those requirements into a practical process flow and evaluate equipment and suppliers.

This guide is for mine owners, project managers, process engineers, and procurement teams planning a new crushing line or reviewing an existing one. It can also help buyers prepare a clear request for quotation before comparing equipment suppliers. We focus on the decisions that influence the flowsheet and equipment configuration, rather than treating a crusher as a standalone purchase.
Material is first delivered to a feed system, commonly involving a hopper and feeder. The feeder regulates the flow to the primary crusher, which reduces large pieces to a size that downstream equipment can handle. A screen then separates material by size: product that meets the specification can move onward, while oversize material may return for further crushing.
For a multi-stage plant, secondary and sometimes tertiary crushers further reduce the material. Screens between or after stages control the product size and help maintain the intended circuit. Conveyors, transfer points, dust-control measures, and electrical and control systems connect the process; their layout should be considered alongside the main machines.
These are equipment roles, not a universal equipment prescription. Crusher selection and circuit design require review of the ore, operating targets, and site constraints. For example, abrasive or hard material can influence the choice of crushing method and wear components, while sticky or wet feed may affect feeding and screening decisions.
Start with the material rather than a preferred machine model. Useful inputs include ore type, hardness, abrasiveness, moisture, clay content, maximum feed size, and any variability in the deposit. These characteristics affect how reliably material can be fed, reduced, screened, and conveyed.
Next, define what the crushed material must do. A plant feeding a downstream concentrator may need a specific size distribution, while a project supplying aggregate or another market may have different product requirements. Clarify whether the line needs one product size or several, and whether the crushing circuit must operate continuously or accommodate variable production schedules.
The figures below show the kind of information a buyer might include in an early project brief. They are illustrative planning inputs, not recommended design values or performance guarantees. A supplier should confirm the actual equipment configuration against the ore test information and operating requirements.
| Project input | Illustrative example | Why it matters |
|---|---|---|
| Maximum feed size | 300 mm | Helps assess feed handling and primary crusher requirements. |
| Nominal throughput target | 100 t/h | Informs equipment sizing and circuit capacity review. |
| Target product size | 20 mm | Helps determine the number of crushing and screening stages. |
Document the expected feed-size range, not just the largest piece, and describe the target product using the size specification relevant to the project. State whether the product must meet a maximum size, a grading range, or multiple size fractions. If the ore varies by location or season, share the known range rather than relying on a single sample description.

Clarify the required hourly and daily production basis, planned operating hours, and whether the stated throughput refers to feed or finished product. Also provide site details that can affect layout and equipment integration, such as available space, elevation changes, power supply, and environmental or dust-control requirements. A capacity figure without these conditions can lead to proposals that are difficult to compare.
Review the proposed sequence from feed to final product, including screen openings, oversize return paths, transfer points, and any bypass or stockpiling arrangements. Ask how the design responds if feed size or ore characteristics vary. A technically suitable crusher can still be part of an unsuitable line if upstream feeding, screening, or conveying is not coordinated.
Ask what wear parts are expected, how they are replaced, and what access is needed for inspection and maintenance. Confirm which components are included in the quotation and which are excluded, such as supporting steelwork, electrical equipment, installation, or commissioning. Clarifying the supply boundary early makes it easier to compare the true scope of different offers.
There is no reliable universal price for an ore crushing production line because the scope changes with capacity, ore properties, equipment configuration, automation, and site requirements. A quotation may cover a single machine or a broader package including feeders, screens, conveyors, and supporting systems. Request an itemized proposal that states the design assumptions, included equipment, exclusions, and any optional items.
For project equipment, minimum order requirements and production lead time depend on the supplier’s product scope, configuration, and current schedule. Buyers should ask for a written delivery estimate and confirm when the lead-time clock starts—for example, after technical approval or receipt of agreed project information. Installation, shipping, and commissioning schedules may be separate from equipment manufacturing time.
Evaluate a supplier by the clarity and completeness of its technical response, not only by the headline price. We recommend asking each shortlisted supplier to respond to the same project data and identify any assumptions or missing information. This helps your team compare proposals on a consistent basis.
Be cautious of proposals that promise a fixed output without stating the material and operating conditions behind it. Likewise, an equipment list alone is not enough to verify that the circuit can achieve the required product. Ask for clarification wherever a performance assumption, responsibility, or project interface is unclear.
A suitable ore crushing production line starts with a defined process goal and reliable information about the ore, feed size, capacity, and required product. The typical circuit combines feeding, primary crushing, screening, and additional crushing stages or oversize recirculation where the application requires them. Equipment should be assessed as an integrated system, with operating conditions, maintenance, layout, and supply scope included in the decision.
To move your project forward, prepare the available material data, target throughput, product-size requirements, site constraints, and preferred delivery scope. We at DAHONGLI can use these inputs to discuss a project-specific crushing-line configuration and clarify the equipment and support included in a proposal.
