A fine sand production line processes suitable feed material through screening, washing, fine-particle recovery, dewatering, and material handling to produce sand that meets a buyer’s target grading and cleanliness requirements. The right equipment depends on the feed’s particle-size distribution, clay content, moisture, desired product specification, and required throughput. We recommend confirming these inputs before selecting machines, because a flow sheet designed for clean crushed rock may not suit a clay-rich or highly variable feed. This guide explains the typical process and the key questions to discuss with a supplier such as DAHONGLI.
This guide is intended for mine owners, aggregate producers, project contractors, and procurement teams evaluating a new line or upgrading an existing sand plant. It can also help engineering teams prepare the information needed for a preliminary equipment proposal. Use it as a planning reference rather than a fixed design: final machine configuration should be based on the material, site conditions, and required product quality.
A fine sand line separates and conditions particles so that saleable sand can be recovered while unwanted oversize, clay, and excess water are managed. A common process begins with feed screening, followed by washing or classification, fine-sand recovery, dewatering, and product stockpiling. Depending on the feed and target product, a line may also include crushing, attrition scrubbing, or water-recycling equipment. Not every project needs every stage, so the process should be matched to actual material test results.
Some plants also collect, settle, or recycle process water. Water management is a design consideration, not an automatic feature of every line: the required tanks, pumps, and treatment equipment depend on water availability, site rules, and the chosen process. During early planning, ask the supplier to show where water enters, where solids leave, and how circulating water will be managed.
Fine sand can be produced from different feed sources, including crushed rock and sand-and-gravel deposits. These materials can vary in hardness, particle shape, gradation, and clay content, all of which affect equipment choice and process settings. The intended use also matters: construction, concrete, mortar, and other applications may require different grading and cleanliness criteria. Confirm the applicable customer or project specification before treating any particular size range as the product target.
For a preliminary discussion, buyers can describe the desired product using a grading range and the sieve or testing method required by their market. As an example only, a project team might request product mainly between 0.15 mm and 2.36 mm; this is a planning target, not a universal definition of fine sand. Feed top size is another useful design input: a buyer might state a maximum feed size of 5 mm for a washing-and-recovery discussion. Both figures must be checked against the material and the final specification.

Before choosing machines, gather representative information about the feed, including its particle-size distribution, moisture, clay content, and any oversize fraction. Provide the target product grading and the required operating capacity in tonnes per hour. For example, 50 t/h can be used as an illustrative nominal capacity in an initial project brief, but it is not a standard line rating or a promise of output. Confirm how the supplier defines capacity, what feed conditions it assumes, and whether the figure applies to the whole plant or a specific machine.
The cost of a fine sand production line depends on its capacity, equipment configuration, material characteristics, automation scope, and project location. Installation, structural work, conveyors, electrical systems, spare parts, and water-treatment equipment may be included or quoted separately, so compare offers using the same scope. Minimum order requirements and lead times are supplier- and project-specific; we recommend requesting a written quotation that identifies the equipment list, exclusions, delivery terms, and schedule assumptions. A complete project brief usually makes quotations easier to compare and reduces uncertainty during technical review.
Ask potential suppliers to explain the proposed process from feed entry to finished product, and to identify the assumptions behind their equipment selection. Request a clearly itemized equipment list, interface information, utility requirements, and a site layout suitable for technical review. Clarify what support is available for installation, commissioning, operator guidance, and after-sales service, and confirm which items are included in the offer. Where material behavior is uncertain, discuss whether representative sample testing or additional process review is appropriate before finalizing the design.
At DAHONGLI, we work with buyers to review project requirements and develop a suitable fine sand production line proposal within the agreed scope. Sharing feed data, target grading, required capacity, site constraints, and utility information helps our team assess equipment options and process interfaces. We can also clarify what information is still needed before a configuration or quotation can be confirmed. Final selection remains project-specific and should be based on verified technical inputs.
A fine sand production line typically combines feed preparation, screening, washing or classification, fine-particle recovery, dewatering, and product handling. The best equipment arrangement depends on the feed material, product specification, throughput requirement, water conditions, and site layout; no single flow sheet is suitable for every project. Treat example values such as a 5 mm feed top size, a 0.15–2.36 mm product range, or a 50 t/h nominal capacity as planning inputs only, not universal standards or guaranteed performance.
To move forward, prepare representative feed information, define the required product grading and capacity, and document site and utility constraints. Then ask suppliers to explain their process assumptions, equipment scope, water-management approach, and service responsibilities. Contact DAHONGLI with these details to begin a technical discussion and request a project-specific equipment proposal.
