Choosing a mobile crushing plant starts with the material you need to process and the products you plan to sell. Feed size, rock characteristics, required output and site conditions all affect the equipment configuration.
For quarries, aggregate producers and new crushing projects, defining these requirements before comparing models helps make proposals easier to assess. For an existing plant upgrade, the same information helps identify which parts of the current process need attention.
The following five inputs provide a practical starting point.
| Project input | What to confirm | What it influences |
|---|---|---|
| Material and feed | Rock type, maximum and typical feed sizes, moisture and clay | Crusher selection, feeding and material preparation |
| Finished products | Required fractions, application, grading and particle shape | Crushing stages, screening and shaping |
| Required output | Feed throughput, total finished output and output by fraction | Capacity balance across the process |
| Site and power | Working space, loading access, stockpiles and power supply | Layout, conveyors and drive arrangement |
| Relocation and service | Move frequency, transport conditions and maintenance access | Chassis choice, setup and service planning |
1. Understand the Material and Feed Conditions
A rock name is a useful starting point. Equipment selection also needs information about how that material behaves during processing.
Confirm the material’s hardness and abrasiveness where known. These characteristics influence the crushing method and expected wear. Jaw crushers are commonly considered for primary crushing of abrasive rock, while impact crushing may suit less abrasive materials. The final choice requires the feed and product requirements to be reviewed together.
Record both the largest pieces and the typical feed size distribution. A feed containing occasional oversized lumps needs a different review from consistently sized material.
Moisture and clay content also matter. Sticky material can affect feeding and processing, so describe the conditions you actually observe. Material photos, measured moisture and available test results are more useful than an assumption based on the season.
Prepare: rock identification, material photos with a size reference, maximum feed size, typical grading and any available material test results.
2. Define the Finished Products
List the products you need to produce, their intended uses and their quality requirements.
For example, a project might require 0–5 mm, 5–10 mm and 10–20 mm fractions. These are illustrative size ranges; the actual specifications should follow your customers’ requirements.
Also confirm whether buyers specify grading, particle shape or limits on fines. A maximum particle size alone does not describe every aspect of product quality.
These requirements help determine the reduction needed, the screening arrangement and whether a shaping stage should be considered. Scalping and final classification perform different duties, so the screening equipment should match its position in the process.
If the product is intended for mortar or another application with particular sand requirements, provide the relevant grading and quality specifications early.
Prepare: a product list, required size ranges, end uses and any customer specifications or sieve analysis.
3. State the Required Output Clearly
When discussing capacity, explain what the number represents:
- Fresh feed entering the plant.
- Total finished material leaving the process.
- The output of a particular product fraction.
For a plant producing several fractions, the required quantity of each product helps define the production objective.
As an illustrative planning example, a customer might request 100 tonnes per hour of finished material, comprising 60 tonnes of one fraction, 30 tonnes of another and 10 tonnes of a third. This is a statement of demand, not a predicted equipment result. Whether a proposed process can achieve that distribution needs technical assessment.
Review the feeder, crusher, screen and conveyors as a connected system. In a closed circuit, oversize material returned for further crushing also contributes to the load on the equipment.
Ask suppliers to state the material, feed grading, product requirements and operating assumptions behind a capacity estimate.
Prepare: the capacity definition, total output target, required product split and planned operating hours.
4. Review the Working Layout and Power Supply
The layout needs to show how equipment, people and material will move around the site.
Include room for:
- Excavator or loader access to the hopper.
- Equipment and conveyors in their operating positions.
- Separate stockpiles and finished material removal.
- Inspection, maintenance and replacement of wear parts.
- Connections to existing equipment when upgrading a line.
A photograph of a mobile unit may not show its full operating footprint. Request operating dimensions and review the proposed arrangement against a site sketch or drawing.
Confirm the available power supply and proposed drive arrangement. Mobile and portable equipment may use different combinations of diesel, electric or hydraulic drives. Grid connection and generator operation depend on the selected equipment.
Prepare: site dimensions, photographs, loading method, proposed stockpile positions and available power information.
5. Consider Relocation and Maintenance
Describe what mobility means for your operation: repositioning within a quarry, moving between nearby work areas or transporting equipment to another project.
Track-mounted equipment can provide on-site movement, while wheel-mounted and truck-mounted arrangements offer other relocation options. Compare the actual transport requirements, setup procedure and working arrangement for the proposed units.
Review transport dimensions and weight, conveyor folding, support arrangements and the equipment needed for loading or relocation. An integrated unit and a combination of separate units may create different transport and setup requirements.
Service planning should cover access to wear parts, routine maintenance tasks and how replacement parts will be supplied.
For an upgrade, share the current equipment list, layout and the production problem you want to improve. Increasing crusher capacity may also require changes to downstream screening or conveying.
Prepare: expected move frequency, relocation route information, current equipment details and maintenance expectations.
What to Send Before Requesting a Proposal
A useful project enquiry includes:
- Project location and whether it is a new plant or an upgrade.
- Material type, photographs and available test data.
- Maximum feed size and typical feed grading.
- Required product sizes and quality specifications.
- Total output target and required output by fraction.
- Site dimensions, loading method and power supply.
- Relocation requirements.
- Existing equipment details, where applicable.
If some information is unavailable, identify what still needs checking. An initial discussion can help establish the next measurements or tests needed.
