How to Design a Stone Crushing Plant by Capacity: 100 TPH, 200 TPH and 300 TPH | HAMAC

How do you design a 100 TPH, 200 TPH or 300 TPH stone crushing plant? Capacity is the starting point, but it is not the complete design. A reliable crushing and screening plant must match the raw material, maximum feed size, required aggregate sizes, operating schedule, site layout and future expansion plan.

A complete stone crushing plant normally includes a hopper, vibrating feeder, primary crusher, secondary or tertiary crusher, vibrating screen, belt conveyors, return conveyor and finished-product stockpiles. Depending on the project, a sand making machine, sand washing machine, dust-control system and automatic control system may also be required.

HAMAC provides stationary crushers, modular crushing plants, tyre type mobile crushers, tracked crushing plants, jaw crushers, impact crushers, cone crushers, vibrating screens, vibrating feeders, belt conveyors and sand washing equipment for aggregate, quarry, mining and recycling projects.

1. What Material Will You Crush?

The first question is not “Which crusher should I buy?” It is “What material will I process?” Limestone, granite, basalt, river stone and recycled concrete do not require the same crushing route.

Material hardness, abrasiveness, moisture, clay content, fines content, maximum block size and contaminants all affect equipment selection, wear cost, crushing stages and final aggregate quality.

For many aggregate projects, limestone is commonly processed through a jaw crusher and impact crusher route, while granite and basalt commonly use a jaw crusher and cone crusher route. This is a planning direction only; final configuration must be confirmed by the actual material, feed size, finished product requirements and operating conditions.

2. What Is the Maximum Feed Size?

Maximum feed size determines the hopper, vibrating feeder, pre-screening section and primary crusher feed opening. A crusher can lose output or block when oversized rocks enter the chamber, especially when feed is uneven or slab-shaped.

As a general planning reference, maximum feed size is commonly kept within approximately 60% to 80% of the primary crusher feed opening. Final selection should also consider material shape, feed-size distribution, feeder design and operating practice.

Before choosing a jaw crusher, confirm the largest expected rock size in millimeters, not only the average rock size. If oversized rock occurs regularly, it may require secondary breaking, improved blasting control or a larger primary crusher feed opening.

The overall crushing process should also avoid unnecessary oversize entering the crusher. Industry process-planning guidance highlights that oversize boulders can affect feeder and crusher performance, increase handling difficulty and raise wear and maintenance requirements.

3. What Finished Aggregate Sizes Do You Need?

The required final products determine the number of screening decks, the screen openings, the return circuit, the number of product conveyors and the stockpile layout. A plant producing one road-base product is not designed in the same way as a plant producing several concrete aggregate sizes and manufactured sand.

The flowsheet should be designed around saleable products, not only total tonnage. More finished-product sizes usually require more screening capacity, more conveyors, more stockpile space and better product-separation planning.

For broader industry context, crushed stone is a major raw material for construction and related industries; its value depends heavily on consistent grading and suitability for the intended application. See USGS crushed stone statistics and information.

4. What Capacity and Operating Schedule Are Required?

When customers say “I need a 200 TPH crushing plant,” the next question should be whether this means rated machine capacity, average feed capacity or stable saleable output after screening. The most useful project target is stable output of qualified aggregate at the required sizes.

Required Hourly Capacity = Target Daily Saleable Output ÷ Planned Operating Hours

For example, a project targeting 1,600 tonnes of saleable aggregate per day over two 8-hour shifts needs an average saleable output target of 100 TPH. Actual equipment selection should still include reasonable planning allowance for feed variation, routine maintenance, screen efficiency and return material.

A capacity figure alone does not define the correct equipment. Plant throughput is affected by feed size, material hardness, moisture, clay, crusher settings, screen efficiency, recirculating load and operating discipline.

Detailed capacity guides can be developed as separate pages for 100 TPH stone crushing plants, 200 TPH stone crushing plants and 300 TPH stone crushing plants.

5. How Many Crushing Stages Are Needed?

The number of crushing stages depends on total reduction required from the largest feed material to the final products. Harder rock normally requires more controlled crushing stages than softer rock. More equipment does not automatically create a better plant; each stage should have a clear purpose.

Industry process-planning guidance notes that jaw crushers commonly provide a reduction ratio of approximately 3:1 to 5:1, horizontal-shaft impact crushers approximately 5:1 to 10:1, and secondary cone crushers approximately 3:1 to 4:1. These are general planning ranges, not performance guarantees, because actual results depend on material properties, crusher settings and feed conditions.

6. Which Supporting Equipment Controls Real Output?

The main crusher is important, but it is not the only factor that determines stable plant output. Many crushing plants lose capacity because the feeder, screen, return conveyor, product conveyor or stockpile arrangement is undersized or poorly matched.

Screening and return flow are especially important in multi-size aggregate production. If the screen is undersized or the return conveyor cannot manage oversize material, the crushing circuit may produce high recirculating load instead of stable saleable output.

7. Should the Plant Be Stationary, Modular or Mobile?

For projects with changing work locations, compare project duration, annual operating hours, material type, transport frequency and ownership cost before selecting rental or purchase. Read Mobile Crusher: Buy or Rent? A Practical Cost and Project Decision Guide.

8. How Should You Plan Layout, Dust Control and Future Expansion?

A crushing plant layout should include more than the main crushers. Plan space for raw-material unloading, hopper loading, maintenance access, lifting equipment, screens, conveyors, product stockpiles, truck loading, electrical room, dust-control systems and safe traffic routes.

For future growth, reserve space, power and material-handling interfaces for an additional crusher, vibrating screen, sand making machine, sand washing machine, return conveyor or product conveyor. This helps avoid major reconstruction when capacity or product requirements change.

Dust-control planning should begin during plant design. Crusher feed points, crusher discharge points, vibrating screens, conveyor transfer points and stockpile discharge areas are common dust-generation locations. Depending on the material and local requirements, water spray, enclosure, conveyor sealing, local extraction or dry dust collection may be considered.

NIOSH notes that silica content and exposure risk vary by material: sandstone and granite average about 70% to 90% silica, while limestone averages about 20% to 30%. For enclosed cabs and operator booths, NIOSH reports dust reductions of 65% to 95% after upgrades compared with outside levels; it also identifies positive cab pressure above 0.01 inches of water gauge and high-efficiency filtration as important factors. Project requirements and local regulations must always be verified before final design.
