Mineral processing equipment separates valuable minerals from mined material through operations such as crushing, grinding, screening, classification, separation, and dewatering. The right equipment depends on the ore’s properties, the required product, the planned throughput, and the process route—not simply on the equipment category. This guide explains the main equipment types, how they fit into a processing circuit, and what to check before requesting a quotation. We recommend using representative ore data and a clearly defined process goal to compare options.

This guide is intended for mine owners, project engineers, plant managers, procurement teams, and contractors evaluating mineral processing equipment. It can support early-stage planning or help structure an equipment inquiry for an existing plant. It is not a substitute for ore testing, process design, or a project-specific engineering review. Final equipment selection should be checked against the material and operating conditions at the site.
Mineral processing equipment changes the size, distribution, or composition of mined material so that valuable minerals can be recovered or the product can meet a defined specification. A typical process may reduce run-of-mine rock, separate particles by size, liberate minerals through grinding, and concentrate them using a suitable separation method. Not every plant uses every equipment category. The flowsheet depends on mineralogy, liberation characteristics, the presence of unwanted material, and the required product.
Crushers reduce large pieces of rock into smaller feed for downstream equipment. Jaw crushers are commonly considered for primary size reduction, while cone or impact crushers may be evaluated for later stages depending on the rock and product requirements. Screens separate material by size, allowing correctly sized particles to move forward while oversize material can be returned for further crushing. When comparing options, check feed size, hardness, moisture, desired product size, and expected operating rate.
Grinding mills reduce particle size further, often to support mineral liberation. Ball mills and other mill designs are selected according to ore characteristics, circuit layout, product-size targets, and operating considerations. Classifiers, including hydrocyclones in suitable circuits, separate particles by size so that material can be returned for further grinding or sent to the next process stage. A target such as a product P80 of 75 μm may be used as a preliminary design example, but the correct target must be established through process testing and engineering.
Separation equipment exploits differences between valuable minerals and gangue, such as density, magnetic response, or surface properties. Depending on the ore, a flowsheet may include gravity concentrators, magnetic separators, or flotation equipment. Each method has specific feed and process requirements, so a machine should not be selected on its name alone. Ask how the proposed equipment matches the mineralogy, particle-size range, and recovery objectives identified for your project.
Dewatering equipment, such as thickeners and filters, helps separate water from process solids, while pumps, feeders, conveyors, and storage systems move material through the plant. These components affect the continuity of the full circuit, not just individual machine performance. Consider slurry characteristics, moisture requirements, water management, elevation changes, and available space. A dewatering choice should be evaluated alongside the destination and handling requirements of the resulting solids and water.
Equipment selection starts with the material and the duty it must perform. An abrasive, hard feed may place different demands on crushing and wear components than a softer or more friable ore. Fine particles, variable moisture, or a broad feed-size distribution may also influence screening and separation decisions. Where information is incomplete, treat any preliminary equipment recommendation as conditional and identify what testing or site data is still needed.
| Process stage | Typical equipment | Key information to confirm |
|---|---|---|
| Size reduction | Jaw, cone, or impact crusher | Feed size, ore hardness, abrasiveness, target product |
| Size separation | Vibrating screen or classifier | Required cut size, moisture, feed distribution |
| Fine grinding | Grinding mill and classification equipment | Target particle size, ore response, circuit arrangement |
| Concentration | Gravity, magnetic, or flotation equipment | Mineralogy, particle-size range, separation objective |
| Water and solids management | Thickener, filter, pump, or conveyor | Slurry properties, moisture target, site layout |
State what the equipment must accomplish: reduce feed size, achieve a specified separation, produce a concentrate, or manage process water. Then identify the required product quality and the downstream process that will receive the output. This makes it easier to compare proposals on equivalent duties. If the process objective is not defined, equipment specifications may appear comparable while describing different operating conditions.

Provide the supplier with the available information on feed size, mineral composition, hardness, moisture, and variability. Include planned throughput in metric tonnes per hour (t/h), and clarify whether that figure is an average, peak, or design rate. If laboratory data is not yet available, say so rather than treating assumptions as confirmed values. A representative sample is important for testing; the required sample mass depends on the test program, and a preliminary sample plan should be agreed with the testing facility.
Specify product-size targets, separation objectives, operating schedule, and relevant site constraints. For example, a screen aperture of 10 mm is a measurable specification, but its suitability depends on the feed and process duty. Also document available power, water, footprint, climate, and access for maintenance. These details can influence the equipment configuration and the supporting systems required.
Evaluate how each machine connects to the equipment before and after it. A crusher, screen, and conveyor must be considered as a connected material-handling system, while a mill and classifier should be reviewed as a grinding circuit. Confirm interfaces, controls, foundations, electrical requirements, and any items excluded from the supplier’s scope. This helps identify gaps before procurement or installation.
Mineral processing equipment prices vary with equipment type, capacity, configuration, materials of construction, accessories, and project scope. A quotation may cover a standalone machine or a broader package, so compare the included items and exclusions rather than headline price alone. Minimum order requirements also vary by supplier and product; confirm them directly if you are sourcing a single machine, spare parts, or a multi-equipment package. Lead time depends on final specifications, manufacturing schedule, inspection requirements, and shipping arrangements, so request a project-specific estimate.
Compare suppliers using the same process data and scope wherever possible. Ask for clarification when specifications use different assumptions, and request supporting technical information relevant to your application. Avoid relying on a single capacity figure without understanding the material and operating conditions behind it. For a new or variable ore, consider whether laboratory or pilot testing is needed before finalizing the flowsheet.
One frequent mistake is choosing a machine based only on nominal capacity while overlooking feed characteristics or product requirements. Another is treating a preliminary flowsheet as fixed before mineral testing confirms the separation approach. Buyers can also underestimate auxiliary equipment, such as feeders, pumps, conveyors, water systems, and wear parts, which may be essential to plant operation. Ask suppliers to make assumptions and exclusions visible so that you can assess the full project scope.
At DAHONGLI, we work with buyers evaluating mining machinery and mineral processing equipment for different project requirements. To help us understand your application, share the mineral or ore type, available feed data, required throughput, target product, process stage, and installation location. If you have a flowsheet, equipment list, drawings, or test results, include them with your inquiry. Our team can then discuss suitable equipment options, technical requirements, and the information needed for a project-specific proposal.
The best mineral processing equipment is the equipment that fits the ore, process objective, capacity, and site conditions as part of a workable circuit. Begin by defining the feed and product requirements, then compare equipment types, specifications, supplier scope, and support on an equivalent basis. Where critical ore data is missing, identify the uncertainty and arrange appropriate testing before committing to a final selection. Contact DAHONGLI with your project details to discuss equipment options and the next steps for a quotation.
