Minerals crushers reduce run-of-mine rock and other mineral materials to sizes suitable for transport, screening, grinding, or further processing. The right crusher depends on the material’s hardness, abrasiveness, moisture, feed size, required product size, and target throughput. In many plants, crushing is a staged process: a primary machine handles large feed, while secondary or tertiary crushers refine the product. This guide explains the main crusher types, where they are used, and how to assess equipment and suppliers before requesting a quotation.
This guide is intended for mine owners, mineral processors, plant engineers, project contractors, and equipment purchasing teams. It can help buyers preparing a new crushing line as well as teams reviewing an existing circuit. It is also useful when comparing proposals from manufacturers or narrowing down a shortlist before a technical discussion. Because each deposit and plant layout is different, use the guidance as a framework rather than as a substitute for project-specific engineering.
A crusher applies mechanical force to break mineral-bearing rock into smaller pieces. Depending on the circuit, crushing may prepare material for screening, conveying, grinding, or separation processes. A crusher does not by itself determine the final performance of a processing plant: the result also depends on feed consistency, downstream equipment, operating conditions, and maintenance practices.
Plant designers typically divide crushing into primary, secondary, and sometimes tertiary stages. Primary crushing accepts larger material, while later stages progressively reduce it to meet a specified product size. Screening may separate material that is already small enough, helping control what returns for further crushing. The number of stages and equipment arrangement should be determined from the ore and the plant’s production requirements.
Jaw crushers use a fixed jaw and a moving jaw to compress material. They are widely considered for primary crushing where feed may include large, irregular rock. Buyers should assess feed opening, discharge setting, expected capacity, and the nature of the material. Jaw crushers are not a universal choice: very abrasive or unusually shaped feed, site constraints, and required product specifications can affect suitability.
Gyratory crushers are used in some large-scale primary applications, while cone crushers are commonly considered for secondary or tertiary reduction. Both use compression, but their designs and typical duties differ. Selection should account for the feed size, desired product distribution, operating conditions, and whether the machine will work in a circuit with screening and recirculation. Ask suppliers how the proposed model will be configured for your particular duty.
Impact crushers reduce material through impact against internal surfaces or other particles. Hammer crushers use rotating hammers to strike feed material. These machines may be considered where the material and product requirements suit impact-based reduction, but wear, feed characteristics, and the desired particle shape require careful evaluation. For abrasive ores, buyers should specifically discuss wear-part consumption and maintenance access rather than assuming an impact machine will be economical.
Roll crushers draw material between rotating rolls and reduce it through compression or a combination of compression and shear. They may be suitable for particular materials and controlled size-reduction duties. Their suitability depends on feed size, hardness, moisture, and the product specification. Confirm with the supplier whether the proposed roll arrangement can handle the feed without creating unacceptable fines or operating limitations.
Start with representative information about the material, not a machine name. Useful inputs include mineral composition, hardness, abrasiveness, moisture, clay content, and the range of feed sizes. Variations in these properties can change how a crusher performs and how frequently its wear parts need attention. If available, provide test information or a representative sample for technical review.

Next, describe the process duty. A primary crusher in a mine may need to accept coarse, variable feed, while a downstream crusher may be selected to meet a narrower product-size requirement. A plant feeding grinding equipment may have different priorities from one producing aggregate or a saleable crushed product. Share the required capacity and product specification, and explain whether the machine will operate continuously or under variable feed conditions.
The following figures show how a buyer might describe an early-stage requirement; they are examples only, not a recommended machine specification or a DAHONGLI performance claim. A preliminary brief could state a maximum feed size of 500 mm, a target product size of 25 mm, and a required throughput of 100 t/h. Actual equipment selection requires review of the material, operating conditions, circuit design, and the meaning of the target size specification.
Choosing a crusher from capacity alone can lead to a poor match if the feed size, material characteristics, or product target are not also considered. Another common issue is treating a stated capacity as guaranteed without checking the conditions behind it, such as feed distribution and discharge setting. Buyers should also avoid overlooking the surrounding circuit: a crusher may be correctly sized but constrained by feeding, screening, conveying, power, or site layout.
Do not compare quotations only by initial purchase price. Differences in included components, controls, installation scope, wear parts, shipping terms, and after-sales support can make offers difficult to compare. Ask each supplier to identify what is included and what must be provided by the buyer. Where a proposal depends on assumptions, have those assumptions recorded in writing before placing an order.
The price of a mineral crusher depends on factors such as machine type and size, configuration, materials of construction, drive arrangement, included accessories, and project scope. Installation, commissioning, shipping, and spare parts may be quoted separately or included depending on the offer. Request an itemized quotation so you can compare equipment and service scope on a consistent basis.
Minimum order requirements and lead times are supplier- and configuration-specific, so buyers should confirm them directly rather than rely on general estimates. Lead time can be affected by design approval, production scheduling, component availability, inspection, and shipping arrangements. For a more useful quotation, provide the destination, intended application, technical requirements, and target delivery schedule.
As a mining machinery supplier, DAHONGLI can discuss crusher selection and configuration in relation to a buyer’s stated material, capacity, and process requirements. A productive inquiry includes the feed size, target product size, required t/h, material characteristics, site conditions, and any drawings or circuit information available. This allows the discussion to focus on a suitable solution instead of an equipment category in isolation.
The best minerals crusher is the machine that fits the material, process stage, product requirement, and operating conditions—not simply the machine with the most appealing headline capacity. Start by documenting feed properties, size requirements, throughput, and circuit constraints. Then compare crusher types and supplier proposals using consistent assumptions, including wear-part and service considerations.
For a practical next step, prepare a short technical brief with your feed size in mm, target product size in mm, and required capacity in t/h. Include material information, site constraints, and delivery expectations, then send it to DAHONGLI for a project-specific discussion and quotation. Where key data is not yet available, identify it as an estimate so that the supplier can clarify what needs to be confirmed before equipment is finalized.
