Choosing the right crusher starts with your material and process—not with a machine name or a headline capacity. Before requesting a quotation, define the feed material, maximum feed size, required product sizes, throughput, and operating conditions. Then compare crusher types and manufacturers against those requirements, including configuration, wear parts, service support, and the scope of supply. At DAHONGLI, we recommend sharing these details early so we can assess whether a proposed mining machinery solution fits your project.

This guide is for mine operators, mineral processors, EPC contractors, equipment distributors, and procurement teams evaluating a crusher machine manufacturer. It is useful when planning a new plant, replacing an existing machine, or reviewing options for a change in feed material or product specification. It can also help buyers prepare a clearer request for quotation (RFQ). A well-defined RFQ makes it easier to compare proposals on a like-for-like basis.
A crusher reduces the size of rock or other mineral material so it can be handled by downstream equipment or meet a specified product range. Crushing may be arranged in stages, with each stage selected for its feed and product requirements. A complete selection depends on more than the crusher itself: feed arrangement, discharge handling, screening, and process control can all affect the result. We therefore encourage buyers to consider the machine as part of the wider circuit.
Jaw crushers use compression between a fixed and a moving jaw. They are commonly considered for primary crushing of larger feed, including hard and abrasive rock, but the correct choice depends on the material and required duty. Ask the manufacturer to review the maximum feed size, feed characteristics, and the required discharge range before selecting a model.
Cone crushers reduce material through compression between the mantle and concave. They are often evaluated for secondary or tertiary duties where a controlled product size is required. Suitability depends on factors such as feed gradation, material hardness, circuit arrangement, and the desired output. Confirm the operating conditions and configuration with the supplier rather than assuming that a particular crusher type will meet a target by itself.
Impact crushers use impact forces to break material and may be considered where the feed and product requirements suit that method. Material abrasiveness and desired product characteristics are important selection factors because they influence wear and operating considerations. Request information about expected wear parts and maintenance requirements for your specific application. A manufacturer should evaluate your material rather than relying on a general description such as “stone” or “ore.”
Start by describing what enters the machine and what must leave it. Include material type, moisture or clay concerns where relevant, feed size distribution, and whether the material is blasted, screened, or mixed. State the required product sizes and whether they are final products or feed for another process. These details help the manufacturer assess the crusher’s role in the circuit instead of recommending equipment in isolation.
Capacity should be discussed as a process requirement, not treated as a universal machine rating. Actual throughput can depend on feed properties, feed consistency, settings, circuit layout, and operating conditions. For an illustrative RFQ—not a DAHONGLI machine specification—you might state a maximum feed size of 600 mm, a target throughput of 150 t/h, and a product range of 0–25 mm. Replace these example figures with your verified project requirements and ask suppliers to state the conditions attached to any quoted capacity.
Identify whether the crusher will perform primary, secondary, or tertiary reduction and describe the equipment before and after it. Clarify whether the plant operates continuously or intermittently and how material is delivered to the feed point. If the machine is replacing existing equipment, provide the current model, operating issues, and available installation space where possible. This context can reveal constraints that a material description alone will not show.
Share representative information about feed size, gradation, hardness, abrasiveness, moisture, and any contaminants that could affect operation. Define the required product range and explain how it will be measured or used downstream. If you have test results, sample descriptions, or historical operating records, include them with the RFQ. Where information is incomplete, label assumptions clearly and ask the manufacturer what further data is needed.

Review the proposed crusher model, chamber or rotor configuration where applicable, adjustment method, drive arrangement, and included auxiliaries. Check whether the quotation covers items such as motors, control equipment, lubrication systems, installation guidance, and commissioning support, or whether these are separate. Compare wear parts by material, expected replacement approach, availability, and cost basis rather than purchase price alone. Request a clear statement of exclusions and site requirements.
Ask how routine inspection and wear-part replacement are performed, what access and lifting provisions are needed, and which consumables should be stocked. Confirm the machine footprint, connections, foundations, and interfaces against the plant layout. Discuss operator training, spare-parts identification, and the process for obtaining technical assistance. These questions help buyers assess ownership requirements before equipment is ordered.
Crusher pricing depends on the selected model, configuration, materials, accessories, and the commercial scope of supply. Freight, installation, commissioning, and spare parts may be quoted separately, so ask for an itemized proposal with clearly stated delivery terms. Minimum order requirements, if any, should be confirmed directly with the manufacturer because they can vary by product and order scope. Lead time should also be confirmed in writing for the specific configuration and delivery destination.
When comparing offers, check that each supplier is pricing equipment for the same feed conditions, duty, and included scope. A lower initial price may not represent an equivalent proposal if key components or services are excluded. Request clarification where performance assumptions, wear parts, warranty terms, or delivery responsibilities are not stated. This creates a more dependable basis for technical and commercial review.
Ask for evidence that is relevant to your decision, such as technical drawings, product documentation, or a written explanation of the proposed configuration. Do not treat broad claims as a substitute for application-specific details. If the project requires special materials, controls, or plant interfaces, ask the manufacturer to confirm feasibility and scope in the proposal. Keep technical and commercial clarifications together so they can be reviewed consistently.
A frequent mistake is selecting equipment based only on maximum feed size or a quoted throughput figure. Those numbers need context, including material characteristics, product target, and operating conditions. Another risk is specifying a machine before confirming how it will connect to screens, conveyors, or other process equipment. Buyers should also avoid comparing proposals with different scopes or treating an illustrative capacity as a guaranteed result.
Incomplete information can lead to unsuitable recommendations or repeated quotation revisions. If laboratory or site data is unavailable, explain what is known, what is estimated, and what still needs confirmation. Ask the supplier to list assumptions and identify any information needed before final selection. This is more useful than presenting uncertain inputs as fixed facts.
As a crusher machine manufacturer and mining machinery supplier, DAHONGLI can review your application details and discuss suitable crusher options and project requirements. Our assessment depends on the information provided, including material characteristics, feed and product sizes, target capacity, and plant conditions. We can clarify the proposed configuration and the scope of supply for your inquiry. Specific equipment suitability, commercial terms, and delivery schedules should be confirmed for each project.
To begin a technical discussion, prepare your material description, process flow or duty, target product specification, and site constraints. Include drawings, photographs, or operating data if available, and note which figures are confirmed versus estimated. We can then review the request, identify unanswered technical questions, and provide a proposal for your evaluation. This gives your team a practical basis for comparing equipment and planning next steps.
The right crusher is the one selected for the actual material, feed conditions, product requirements, and plant duty—not simply the one with the most attractive headline specification. Define the process, compare complete configurations, and evaluate maintenance, supplier support, and commercial scope alongside the equipment price. When you contact a manufacturer, provide usable project data and ask for assumptions to be stated clearly. Share your application requirements with DAHONGLI to discuss an appropriate crusher solution and request a project-specific quotation.
