An ore crushing plant reduces run-of-mine material into sizes suitable for grinding, separation, or other downstream processing. A typical circuit combines feeding, primary crushing, secondary or tertiary crushing, screening, and material transfer, but the right arrangement depends on the ore, required product size, and planned throughput. To evaluate a line, define the feed characteristics and final product requirements first, then match equipment and circuit layout to those conditions. This guide explains the process, key equipment, selection factors, and information to prepare before requesting a supplier proposal.

This guide is intended for mine owners, project teams, EPC contractors, and purchasing professionals comparing ore crushing plant options. It is useful when planning a new operation, expanding an existing circuit, or replacing equipment that does not meet current production requirements. Because ore properties and site conditions differ, the information here is a decision framework rather than a guaranteed plant design. Final equipment selection should be based on project data and technical review.
Run-of-mine ore is first delivered to a receiving area, where a feeder regulates material flow into the primary crusher. The primary stage handles the largest feed pieces and produces a smaller, more manageable material. Secondary and, where required, tertiary crushers reduce the material further, while screens separate particles by size and return oversize material for additional crushing. Conveyors connect stages and transfer material to stockpiles or the next processing step.
Not every plant needs the same number of crushing stages. A competent ore that can be reduced efficiently may use a simpler circuit, while hard, abrasive, or size-variable feed may require additional crushing or screening stages. The objective is not simply to install more machines, but to produce the required feed for downstream processing with a circuit suited to the ore and operating plan. The process flow should be reviewed as a whole, including material handling and access for maintenance.
Crusher selection should not be made from machine type alone. Ore hardness, abrasiveness, moisture, feed gradation, and the required product shape can all influence which equipment and circuit arrangement are appropriate. A supplier should review these factors alongside the requested throughput and site constraints. Where information is incomplete, treat early equipment recommendations as preliminary.
Ore properties influence crushing performance and the maintenance demands of the plant. Hard or abrasive ores may increase wear on crushing surfaces and other material-contact components, while wet or clay-bearing feed can create handling and screening challenges. The plant designer needs to understand both the material’s behavior and the downstream process requirements. A laboratory assessment or representative sample can help clarify material characteristics when project data is uncertain.
| Project condition | Selection consideration |
|---|---|
| Hard or abrasive ore | Review crusher suitability, wear-part requirements, and maintenance access. |
| Variable feed size | Confirm the feed opening and consider whether scalping or additional screening is needed. |
| Wet or sticky material | Assess feeding, chute design, screening conditions, and material-flow risks. |
| Defined downstream size requirement | Develop the circuit around the target product and confirm how oversize is handled. |
Start with the maximum feed size, feed-size distribution, ore type, moisture conditions, and any known hardness or abrasiveness information. Then state the target product size and whether the requirement is a single size range or multiple screened products. Include the expected operating schedule and design throughput so the supplier can assess the circuit rather than quote an isolated crusher. These values should reflect the project’s operating plan, not a generic plant assumption.
For example, a preliminary inquiry might list a maximum feed size of 500 mm, a target product size of 25 mm, and a design throughput of 100 t/h. These figures are illustrative only and are not a recommendation or a DAHONGLI performance guarantee. Your actual specifications should come from mine planning, process requirements, and material data. State whether figures are firm requirements, estimates, or still under review.

Compare proposed equipment by its role in the process, not only by model name or headline capacity. Check how the primary crusher, secondary stages, screens, feeders, and conveyors are sized and coordinated for your feed and product targets. Ask how the design manages oversize, variable feed, and expected wear. Request clarification on any assumptions that affect the proposed configuration.
Site conditions can change what is practical, including available footprint, elevation changes, power supply, climate, access roads, and the handling method for incoming ore. Confirm whether the proposal covers only major crushing equipment or also includes feeders, screens, conveyors, electrical controls, structural items, and installation guidance. Clear scope boundaries help prevent gaps between equipment supply and site responsibilities. Include dust, noise, and safety requirements in the project specification where applicable.
The investment for an ore crushing plant depends on its capacity, process stages, equipment selection, material of construction, automation scope, and project-specific engineering. Site preparation, civil works, installation, freight, taxes, and commissioning may be priced separately, so compare quotations on a like-for-like scope basis. There is no reliable universal price or minimum order quantity for every plant configuration. Request a scope breakdown and confirm which items are included before comparing offers.
Lead time also depends on the final design, equipment availability, manufacturing schedule, inspection requirements, and delivery arrangements. Ask the supplier to identify key schedule assumptions and the information needed to move from preliminary proposal to confirmed order. A complete technical specification can reduce avoidable clarification during quotation and engineering. Confirm any dates contractually rather than relying on general estimates.
DAHONGLI works with buyers to assess ore crushing plant requirements and discuss suitable equipment and process configurations within the project scope. When evaluating any supplier, request a proposal tied to your material data and operating objectives rather than relying on broad claims. A useful supplier conversation should make design assumptions visible and identify unresolved technical questions. Confirm that the offered services and equipment match your procurement and site requirements.
An ore crushing plant is a coordinated process system, not just a crusher purchase. The most important selection inputs are ore characteristics, feed size, target product size, throughput, site conditions, and downstream process needs. Equipment configuration, project scope, and supplier support should then be reviewed together. If any input is uncertain, identify it clearly so it can be assessed during technical discussions.
To request a preliminary review from DAHONGLI, prepare your available ore description, feed and product size requirements, target throughput, site location, and project schedule. Include process-flow information or drawings if available, and mark estimated values as preliminary. This gives the supplier a practical basis to discuss equipment options, scope, and next steps. A well-defined inquiry is the first step toward selecting an ore crushing plant that fits the project rather than a generic specification.
