To choose an impact crusher, match its crushing design to your feed material, required product size, production target, and site conditions. A horizontal-shaft impact crusher (HSI) is commonly considered for primary or secondary crushing, while a vertical-shaft impact crusher (VSI) is often used for shaping and finer-size reduction. Neither type is right for every material or duty. In this guide, we explain the key differences, outline a practical selection process, and show what information to request when comparing suppliers.

This guide is for quarry operators, aggregate producers, mining companies, contractors, and equipment purchasing teams assessing an impact crusher for a new or existing plant. It is also useful for distributors and project engineers preparing a request for quotation. We focus on practical buying criteria rather than assuming that one crusher configuration fits every application.
An impact crusher reduces material by accelerating it into a rotor-mounted or other impact surface, then breaking it through impact and, depending on the design, further collisions with internal surfaces or other particles. Compared with compression-based crushing, impact crushing can produce a more cubical product in suitable applications. Actual particle shape and size distribution depend on the material, machine configuration, settings, feed conditions, and downstream circuit.
An HSI uses a horizontal rotor to throw material against impact plates or curtains. Depending on its configuration and the process flow, it may be used for primary, secondary, or tertiary reduction. Buyers should check the permitted feed size and material characteristics for the specific model rather than relying on the general label “primary” or “secondary.”
A VSI uses a vertical rotor to accelerate material against anvils, shelves, or other particles, depending on the design. It is often considered when particle shaping or finer reduction is important, including in some aggregate and manufactured-sand circuits. Its suitability depends on feed preparation, material abrasiveness, required grading, and the supplier’s application guidance.
Impact crushers are used in aggregate production, quarrying, mining, recycling, and other bulk-material processing operations. In aggregate plants, buyers may evaluate them for reducing suitable rock and improving particle shape. Recycling applications can include concrete or asphalt, but reinforcement, contaminants, feed consistency, and required separation equipment must be assessed as part of the whole process.
Material properties strongly influence performance and operating cost. Hard, abrasive feed can increase wear on impact surfaces and other wear parts, while wet or sticky feed may create handling or buildup problems depending on the equipment and plant layout. Before choosing a model, provide representative material information and discuss any variability in the feed with the supplier.
Document the material type, hardness or available test information, abrasiveness, moisture, contamination, and expected variation. Record the largest feed size and how consistently material reaches the crusher. If the feed includes multiple sources or seasonal changes, describe the range rather than giving only an average.
Describe the required output in terms of capacity, grading, and end use. Capacity should be discussed as a condition-dependent estimate, because feed characteristics, crusher settings, circuit layout, and operating practice can change actual production. Ask the supplier what assumptions its quoted capacity uses and whether the figure refers to the crusher or the complete plant.
For clarity, a hypothetical RFQ might request 200 tonnes per hour (t/h), a maximum feed size of 600 millimetres (mm), and a target product range of 0–20 mm. These are example buyer requirements, not a recommended specification or a performance claim for any machine. A supplier should confirm whether the proposed crusher and circuit can meet the requirements for the stated material and operating conditions.

Identify whether the crusher will be used at the primary, secondary, or tertiary stage and what equipment feeds it or receives its discharge. Check the required feed opening, rotor or chamber configuration, discharge controls, and compatibility with conveyors, screens, and any existing equipment. If product grading is critical, discuss the full crushing and screening circuit rather than evaluating the crusher in isolation.
Request details on motor power in kilowatts (kW), expected wear-part types, inspection points, adjustment procedures, and maintenance access. Ask how the proposed design handles tramp material or uncrushable objects, if they are relevant to your feed. Also review foundation, lifting, electrical, dust-control, and installation requirements against the actual site conditions.
Impact crusher pricing depends on the model, configuration, materials of construction, included components, control system, and scope of supply. Freight, packing, installation support, spare parts, and commissioning arrangements may also affect the total project cost. Request an itemized quotation that makes inclusions, exclusions, and any optional items clear.
Minimum order requirements and lead times vary by supplier, configuration, and current production schedule. We recommend confirming these details directly in the quotation rather than relying on a general estimate. For project planning, ask the supplier to state the quotation validity, delivery basis, production timeline, documentation, and the conditions that could change the schedule.
Requesting this information helps buyers compare proposals on more than purchase price. It also reveals whether a supplier understands the process surrounding the crusher, including feed preparation, screening, material handling, and maintenance planning. If two quotations use different assumptions, ask both suppliers to clarify them before making a direct comparison.
A frequent mistake is selecting by headline capacity without confirming the material and circuit conditions behind the estimate. Another is treating “impact crusher” as one interchangeable machine category, even though HSI and VSI designs may serve different process needs. Buyers can also overlook wear-part consumption, maintenance access, and downstream screening requirements when focusing only on initial equipment cost.
Avoid sending an incomplete RFQ that lists only a desired output rate. Provide material details, feed size, target grading, operating hours, site constraints, and available utilities where known. If information is not yet available, identify it as unconfirmed and ask the supplier what testing, sampling, or engineering review is needed before final selection.
At DAHONGLI, we support B2B buyers evaluating impact crusher options for mining and aggregate applications. Share your material description, required capacity, feed and product sizes, process position, and site requirements so we can review the application and discuss a suitable configuration. We can also clarify the proposed scope, quotation assumptions, and the information needed to move toward a technical offer.
The right impact crusher is the one that matches your material, process stage, product requirements, and operating conditions—not simply the model with the largest stated capacity. Begin by defining the feed and output, then compare HSI and VSI options, confirm the full circuit requirements, and evaluate maintenance, wear parts, supplier support, and total project scope. As a next step, prepare a complete RFQ and ask each supplier to document the assumptions behind its technical and commercial proposal. Contact DAHONGLI with your application details to discuss an impact crusher solution for your project.
