An ore crushing plant reduces run-of-mine material to sizes suitable for downstream processing, such as grinding, beneficiation, or direct use. A typical process moves through feeding, primary crushing, screening, and—when the product target requires it—secondary or tertiary crushing. The right equipment depends on the ore’s properties, feed size, required capacity, product specification, and site conditions. We recommend defining these inputs before comparing machines or requesting a plant quotation.

This guide is for mining project owners, plant managers, engineering teams, and procurement professionals assessing an ore crushing line. It is useful when planning a new plant, upgrading an existing circuit, or comparing proposals from equipment suppliers. It provides a selection framework rather than a universal equipment specification, because ore and site conditions vary from project to project.
Material is usually delivered to a receiving hopper or feed area, then moved by a feeder to the primary crusher. The primary stage reduces large rocks to a size that can be handled by the next equipment in the circuit. A screen may separate material that already meets a size requirement, while oversize material continues to a secondary crusher.
Where a finer or more controlled product is required, the line may include tertiary crushing and additional screening. Screen oversize can be returned to a crusher, creating a closed circuit that controls the final size distribution. Conveyors connect the stages, and dust-control, guarding, access, and electrical systems must be considered as part of the plant layout.
These are general roles, not a recommendation for every ore. For example, high moisture or clay content can affect feeding and screening, while abrasive material can influence wear-part selection and maintenance planning. A supplier should review representative material information before confirming a configuration.
Begin by describing the feed as it arrives at the plant, not only by naming the ore type. Useful inputs include the expected maximum lump size, size distribution, hardness or breakage characteristics if known, abrasiveness, moisture, and the presence of clay or fines. If material varies by mining zone or season, share that range with the equipment designer.
Next, define what the crushing line must deliver. Specify the downstream process, the required product-size distribution, the intended operating schedule, and the target throughput. A single “nominal size” may not describe the whole requirement; a screen cut point and acceptable oversize proportion can make the request clearer.
For illustration only, a project design brief might state a feed capacity of 150 t/h, a maximum feed size of 600 mm, and a target crushed product with a nominal top size of 20 mm. These figures describe a hypothetical enquiry, not a standard plant or a DAHONGLI performance guarantee. Actual equipment sizing and process flow require project-specific review.
State whether the required throughput is an average, peak, or design rate, and clarify the expected hours of operation. Consider whether the plant must handle feed surges or a variable supply from the mine. These factors influence feeder, crusher, screen, conveyor, and storage requirements across the line.
Choose the number of stages based on the gap between feed size and required product size, as well as the ore’s breakage behavior. A simple circuit can reduce equipment count, but it may not meet a tight product-size specification or provide the flexibility needed for variable feed. Ask the supplier to show where screening occurs and how oversize material is handled.

Review the complete line rather than evaluating each machine in isolation. Crusher discharge openings, screen areas, conveyor widths, transfer points, and access for wear-part replacement should be considered together. Confirm the planned foundations, power supply, control interfaces, dust management, and any site-specific environmental requirements.
Purchase price is only one part of the commercial evaluation. Request details on wear parts, routine maintenance access, recommended spares, installation scope, commissioning support, and the information required for future service. Where operating-cost estimates are provided, check the assumptions and distinguish estimates from measured results.
The cost of an ore crushing plant varies with capacity, equipment configuration, material characteristics, automation level, site conditions, and the boundary of supply. A quotation may cover individual machines only, or it may include feeders, screens, conveyors, electrical controls, and other components. Compare offers on the same scope before treating price differences as directly comparable.
Minimum order requirements and manufacturing lead times are supplier- and project-specific. They can also depend on customization, component availability, drawing approval, and delivery arrangements. Request a written quotation that identifies the equipment list, exclusions, delivery basis, proposed schedule, and any information still needed to finalize the design.
Share representative ore information where available, along with a site layout or space constraints and the required downstream feed specification. If laboratory or geological data are incomplete, identify what is known and what remains uncertain. A responsible proposal should make its assumptions visible instead of implying that one configuration suits every ore body.
As a mining machinery supplier, DAHONGLI can discuss the required process flow and equipment scope for an ore crushing project. To begin a technical enquiry, provide the material type, feed-size range, target capacity, desired product sizes, site conditions, and preferred project schedule. We can use those details to review potential equipment arrangements and clarify which additional information is needed before a proposal is prepared.
For a more useful comparison, request a process description and equipment list alongside the quotation. This helps your team assess whether the proposed plant covers the full path from feed handling to product discharge, and whether the stated assumptions match your operating plan. Final selection should be based on project data and confirmed scope, not on a generic machine specification alone.
An ore crushing plant typically combines controlled feeding, staged size reduction, screening, and material transfer to produce feed suitable for the next process. The best equipment configuration depends on ore characteristics, throughput, feed size, product requirements, and site conditions; there is no single flow that fits every project. Define these inputs first, compare complete process proposals, and verify scope, assumptions, and support before placing an order.
To start a discussion with DAHONGLI, prepare your material and product specifications, expected capacity, and site constraints. This gives the supplier a practical basis for reviewing the process flow and identifying appropriate equipment options for your project.
