FAQ

What capacity is considered a small sand making machine?
There is no universal definition. For this guide, approximately 20–50 t/h is treated as small, while 50–150 t/h is considered small to medium. Final classification depends on the material and process.
Which XINGAONAI model is most suitable for small production?
The PCK0808 and PCK1010 single-rotor models have nominal capacities of 20–40 t/h and 40–50 t/h respectively. They are intended for suitable medium-soft, brittle materials.
Can a small sand making machine process granite?
Not every small machine can. Granite is hard and often abrasive. It normally requires staged crushing and a suitable VSI sand-making or shaping stage rather than a small hammer-type machine.
Can a small machine produce concrete sand?
It can contribute to producing manufactured sand, but the final product must meet the project’s requirements for gradation, cleanliness, fines and particle shape. Screening and possibly classification or washing are also required.

Small Sand Making Machine: Benefits, Limitations and Selection

Release time:2026-03-18 Views:66

A small sand making machine can be a practical choice for a quarry, construction-material producer or recycling operation that does not require the capacity of a large industrial sand plant. However, “small” should refer to the production requirement and equipment configuration—not simply the physical dimensions of the machine.

Selecting a smaller machine can reduce the initial project scale, installed power and space requirement. It does not automatically guarantee low operating costs, portability or compliant manufactured sand. Material characteristics, feed preparation, screening and wear costs remain important regardless of machine size.

This guide explains the real advantages of small sand making machines, their limitations and the information required to select an appropriate model.

What Is Considered a Small Sand Making Machine?

There is no universal capacity standard separating small, medium and large sand making machines. The definition varies between manufacturers, materials and production processes.

For practical project planning, the following ranges can be used as a preliminary reference:

Project levelApproximate sand-making capacityTypical application
Small20–50 t/hLocal aggregate supply, small quarry, recycling or workshop production
Small to medium50–150 t/hCommercial sand production and regional construction projects
Medium150–300 t/hContinuous quarry and batching-plant supply
LargeAbove 300 t/hLarge aggregate plants and infrastructure projects

These ranges describe the sand-making stage rather than guaranteed finished-sand output. Actual production depends on the feed material, required product size, circulating load and operating conditions.

Within XINGAONAI’s current range, the smaller models of the Single Rotor Sand Making Machine provide nominal capacities of 20–40 t/h and 40–50 t/h. These models are more closely aligned with the search intent behind “small sand making machine” than the larger VSI or double-rotor models.

Main Advantages of a Small Sand Making Machine

1. Better capacity matching for small projects

A machine should be selected according to realistic demand rather than the highest possible capacity.

Installing an oversized machine in a low-demand operation may result in:

  • Long periods of underloaded operation

  • Unnecessary installed power

  • Higher initial investment

  • Oversized feeders, screens and conveyors

  • More expensive foundations and electrical infrastructure

A properly selected small machine can operate closer to its intended loading range while meeting the actual production target.

2. Lower initial project scale

A small sand-making unit normally requires less capital than a large-capacity model of the same machine type. The surrounding infrastructure may also be smaller, including:

  • Feed hopper

  • Supporting steel structure

  • Conveyor system

  • Electrical control equipment

  • Foundation

  • Product storage area

This can make small-scale manufactured-sand production more accessible to local quarries, construction-material businesses and operators testing a new market.

However, the complete project cost must still include feeding, screening, dust control, installation, electrical work and spare parts. The crusher purchase price alone does not represent the total investment.

3. Smaller equipment footprint

Small machines generally occupy less installation space than larger industrial models.

This can be useful when:

  • The existing workshop has limited floor space

  • The machine must be added to an existing crushing line

  • The project has restricted foundation space

  • Several product stockpiles must share a compact site

  • The operation is being expanded in stages

The entire production system still requires safe maintenance access and sufficient space for feeders, conveyors and screens.

4. Suitable for phased investment

A smaller production unit allows an operator to begin with a limited capacity and evaluate:

  • Local demand for manufactured sand

  • Actual wear-part consumption

  • Material response during crushing

  • Finished-product acceptance

  • Production and maintenance costs

  • Seasonal changes in demand

If demand increases, the operator can evaluate adding another production unit or upgrading the wider plant.

Expansion should be planned in advance. The existing screen, conveyors and power supply must have sufficient capacity if another machine is added later.

5. Simpler maintenance on suitable machine types

Some small single-rotor and roller machines have relatively straightforward mechanical structures. This may simplify routine inspection and replacement of wear parts.

For example, the PCK single-rotor design uses:

  • One reversible rotor

  • Replaceable hammer components

  • Adjustable grate bars

  • An adjustable hammer-to-grate gap

  • Accessible liners and internal wear parts

A simpler machine does not mean maintenance can be ignored. Rotor balance, bearing lubrication, hammer wear, grate condition and fastener tightness must still be checked regularly.

6. Useful for local raw materials and quarry by-products

A small sand maker can process appropriately sized material that might otherwise have limited value, including:

  • Limestone quarry screenings

  • Selected shale or gangue

  • Dolomite or bluestone

  • Clean recycled concrete fractions

  • Oversized material returned from screening

Material suitability must be confirmed first. Excessive clay, metal, wood, plastic or highly abrasive minerals can reduce performance and increase wear.

For guidance on matching equipment to the source rock, see sand making machine selection by stone type.

7. Easier integration into an existing plant

A small sand-making unit can sometimes be installed as an additional fine-crushing stage in an existing aggregate plant.

Possible objectives include:

  • Processing surplus coarse screenings

  • Increasing the manufactured-sand fraction

  • Producing an additional 0–5 mm product

  • Reducing the amount of unsold quarry by-product

  • Testing a new sand specification

Before installation, the operator should verify whether the existing screen, dust-control system and conveyors can handle the additional material.

Important Limitations of Small Sand Making Machines

The advantages of smaller equipment should not be overstated. A small machine is not appropriate for every project.

Limited capacity

A 20–40 t/h machine cannot support a plant that requires 150 t/h of finished sand. Running a small machine continuously above its intended capacity can increase wear, cause blockages and make product quality unstable.

Not suitable for every stone

A small hammer-type machine may be suitable for limestone, shale or coal gangue but may be uneconomical for highly abrasive granite, basalt or quartzite.

Hard-rock sand production generally requires staged crushing and suitable final-stage equipment, even when the required hourly capacity is relatively low.

A complete line still needs auxiliary equipment

The sand maker normally does not replace:

  • Feeding equipment

  • Primary or secondary crushers

  • Vibrating screens

  • Belt conveyors

  • Dust collection

  • Washing or classification equipment

  • Electrical controls

The required configuration depends on the feed and finished product. See the stone crusher and sand making machine configuration guide for complete-line planning.

Small does not automatically mean portable

A fixed small machine can be easier to transport than a large machine, but it is not automatically a mobile plant.

Frequent relocation requires a properly designed:

  • Skid-mounted structure

  • Trailer or mobile chassis

  • Integrated feeder

  • Conveyor arrangement

  • Electrical connection system

  • Safety access platform

Do not describe a standard stationary machine as portable unless the supplied configuration genuinely supports relocation.

Product quality is not guaranteed by machine size

The finished product depends on:

  • Raw material quality

  • Feed-size consistency

  • Machine settings

  • Wear condition

  • Screening accuracy

  • Recirculating load

  • Fines classification

  • Washing requirements

A small machine can produce a suitable product only when the complete system is correctly configured and the sand is tested against the required specification.

Which Type of Small Sand Making Machine Should You Choose?

Single-rotor sand making machine

A single-rotor machine is the primary option for XINGAONAI’s small-capacity range.

Current product range:

  • Capacity: 20–150 t/h

  • Maximum stated feed size: up to 700 mm

  • Suitable direction: limestone, shale, coal gangue, gypsum, dolomite and similar medium-soft brittle materials

The smaller PCK models include:

ModelNominal capacity
PCK080820–40 t/h
PCK101040–50 t/h
PCK101360–80 t/h

The actual acceptable feed should be confirmed according to the selected model, material characteristics and required discharge size. The maximum published feed value should not automatically be treated as the preferred continuous feed size.

A single-rotor machine may be suitable when:

  • Capacity demand is below approximately 80 t/h

  • Material is brittle and not highly abrasive

  • A relatively simple structure is preferred

  • Adjustable grate control is appropriate

  • The project requires a lower-capacity fixed installation

Roller sand making machine

The Roller Sand Making Machine uses compression between counter-rotating rollers.

Current product range:

  • Capacity: 50–300 t/h

  • Maximum stated feed size: up to 40 mm

  • Suitable direction: medium-hard or softer prepared material

The smallest listed model has a nominal capacity of 50–80 t/h, placing it at the boundary between small and medium production.

It may be considered when:

  • Feed has already been reduced to a suitable size

  • The material is not highly abrasive

  • An adjustable roller gap is useful

  • The plant needs approximately 50–80 t/h

  • Compression crushing is preferred over hammer impact

It should not be selected for highly abrasive granite or quartzite without careful wear evaluation.

VSI sand making machine

A VSI Vertical Shaft Impact Crusher is more suitable for hard-rock sand making and aggregate shaping.

The current product range begins at approximately 70 t/h under center-feeding conditions, so it should not automatically be classified as a small sand maker.

A VSI may still be the correct choice when:

  • The feed is granite, basalt, diabase or river pebble

  • Particle shaping is important

  • Feed has already been reduced to the VSI limit

  • The required capacity justifies the machine

  • Wear costs have been evaluated

The project should not use a small hammer machine merely to obtain a lower purchase price when the material requires a VSI.

Double-rotor sand making machine

The current double-rotor range is approximately 150–300 t/h. It is therefore not a primary recommendation for a page targeting small sand making machines.

It may be considered only when the project’s capacity has grown beyond the small-equipment range.

Where Small Sand Making Machines Are Most Useful

Small limestone quarries

A small single-rotor machine can process suitable limestone feed into fine aggregate or manufactured-sand fractions. The quarry must still evaluate moisture, clay and abrasiveness.

Local construction-material suppliers

A lower-capacity plant can supply local concrete, mortar or paving-material producers when demand does not justify a large centralized plant.

Finished sand must be tested before it is sold for a specified construction application.

Existing aggregate plants

A small machine can process selected screening returns or surplus fine aggregate without replacing the main crushing line.

Construction-waste recycling

Clean, sorted concrete may be processed into recycled fine aggregate. Reinforcing steel, wood, soil and other contaminants must be removed before the material enters the machine.

Product and market testing

A smaller unit can help evaluate a new source material or regional sand market before a larger expansion. Representative production testing is still required.

How to Select the Correct Model

1. Confirm the material

Provide:

  • Rock or recycled-material type

  • Hardness

  • Abrasiveness

  • Moisture

  • Clay content

  • Bulk density

2. Confirm the feed

Specify:

  • Maximum feed size

  • Normal feed-size distribution

  • Hourly feed quantity

  • Percentage of fines

  • Presence of contaminants

3. Define the finished product

The supplier needs to know:

  • Required particle sizes

  • Required gradation

  • Intended application

  • Acceptable fines content

  • Particle-shape requirements

4. Calculate the real capacity requirement

Do not select a machine only from the expected daily sales volume.

Consider:

  • Operating hours per day

  • Planned maintenance time

  • Seasonal demand

  • Screen efficiency

  • Circulating material

  • Required finished-product yield

For example, a project requiring 200 tonnes of finished sand per day does not necessarily need a 25 t/h machine if it operates for only five effective hours.

5. Evaluate total operating cost

Compare:

  • Power consumption

  • Wear-part consumption

  • Lubrication

  • Labour

  • Maintenance time

  • Screen and conveyor requirements

  • Finished-product yield

  • Unplanned downtime

A smaller machine may have a lower total power rating but does not always have a lower cost per tonne.

6. Test representative material

A material test can help confirm:

  • Actual throughput

  • Discharge-size distribution

  • Fines production

  • Wear behaviour

  • Need for recirculation

  • Suitability for the intended sand product

Common Purchasing Mistakes

Choosing the smallest machine only to reduce price

If the selected machine cannot meet the required capacity, it may operate continuously under overload and create a production bottleneck.

Ignoring raw-material abrasiveness

A low-capacity project can still have severe wear if it processes granite, basalt or quartz-rich material.

Assuming the machine produces saleable sand by itself

Screening and classification are necessary to control finished-product size. Washing or dust separation may also be required.

The complete stone-to-sand process explains how the sand-making stage works with the rest of the plant.

Selecting from motor power alone

Motor power does not determine material suitability, finished-product quality or actual plant capacity.

Believing every small machine is mobile

Mobility must be designed into the supporting chassis, conveyors, feed system and electrical installation.

Expecting an immediate return on investment

Profitability depends on local sand prices, raw-material cost, utilisation rate, wear cost and market demand. A small purchase price does not guarantee a quick return.

Conclusion

The main advantage of a small sand making machine is not simply that it is cheaper or physically smaller. Its real value is the ability to match a limited production requirement without installing an unnecessarily large system.

For suitable limestone, shale, coal gangue and similar brittle materials, a small single-rotor machine can provide a practical 20–50 t/h starting point. A roller machine may suit prepared medium-soft feed at approximately 50–80 t/h, while hard and abrasive material may still require a VSI and staged crushing even when project capacity is relatively low.

The final selection should be based on material testing, feed size, finished-product requirements and total operating cost. Correctly sized equipment can reduce unnecessary investment, but only a properly configured production system can deliver stable manufactured-sand quality.
