Small Scale Crushing Projects
#1
Introduction
Small‑scale crushing has become an increasingly practical solution for landowners, contractors, and small operators who need to process concrete, rock, or demolition debris on their own sites. Rising transportation costs, limited availability of fill material, and the growing emphasis on recycling have pushed many people to consider compact crushing equipment as a viable investment. In many regions, the cost of hauling debris to disposal sites has increased by more than 40% over the past decade, while the availability of free fill has sharply declined. These pressures have made on‑site crushing not only convenient but economically strategic.
A common scenario involves a landowner who has accumulated hundreds of loads of broken concrete while reshaping a property—such as reducing the size of a pond or leveling uneven terrain. Instead of paying for additional fill or waiting for free material that may never arrive, crushing existing concrete into usable aggregate can turn a liability into a resource.

Why Small Scale Crushing Makes Sense
Economic Efficiency
Crushing concrete on site eliminates hauling fees, which often range from 10 to 25 dollars per ton depending on region. For a project involving 200 truckloads of concrete—typically 2,000 to 3,000 tons—the savings can exceed 20,000 dollars. Additionally, the resulting crushed material can replace purchased fill, which may cost 8 to 15 dollars per ton.
Material Control
Producing your own aggregate allows you to control:
  • Gradation
  • Compaction quality
  • Moisture content
  • Volume availability
This is especially valuable when filling ponds, building access roads, or preparing building pads.
Environmental Benefits
On‑site crushing reduces:
  • Fuel consumption
  • Dust from long‑distance hauling
  • Landfill usage
  • Carbon emissions
A study from several U.S. states found that mobile crushing reduces CO₂ output by up to 65% compared to hauling debris to a remote facility.

Types of Small Scale Crushing Equipment
Modern compact crushers are far more capable than their predecessors. Manufacturers have focused on portability, fuel efficiency, and ease of maintenance. Several categories dominate the small‑scale market.

Micro Jaw Crushers
Terminology Note 
Jaw Crusher: A machine that uses two plates—one fixed, one moving—to compress and break material.
Micro jaw crushers are the most common machines used for small projects. They are compact, towable, and capable of processing concrete with rebar. These units rely on a simple mechanical principle: the moving jaw pushes material against the fixed jaw, breaking it into smaller pieces.
Development History
Jaw crushers date back to the mid‑19th century, originally developed for mining. Over time, manufacturers miniaturized the design to serve construction and demolition contractors. By the early 2000s, portable micro crushers emerged as a new category, driven by demand for on‑site recycling.
Modern Features
  • Output: 10–80 tons per hour
  • Feed size: 6–12 inches
  • Power: Diesel or electric
  • Weight: 2–8 tons
Market Adoption
Micro crushers have seen rapid growth. Some manufacturers report year‑over‑year sales increases of 20–30% as small contractors adopt on‑site recycling equipment.

Compact Impact Crushers
Impact crushers use high‑speed rotors to shatter material. They produce more uniform, cubical aggregate but consume more fuel. They are ideal for asphalt, brittle concrete, and softer rock.
Advantages
  • High reduction ratio
  • Excellent shaping
  • Fast throughput
Limitations
  • Higher wear costs
  • Not ideal for heavily reinforced concrete

Mobile Crushing Systems
Mobile crushing systems combine feeders, screens, and crushers into a single platform. They are used when a project requires multiple material sizes or continuous production. These systems are increasingly popular for contractors who want to avoid hauling debris off‑site.

Choosing the Right Equipment for a Small Project
Selecting the correct machine depends on several factors.

Key Considerations
  • Volume of material 
    For 200 loads of concrete, a micro jaw crusher is typically sufficient.
  • Material hardness 
    Reinforced concrete requires a jaw crusher; asphalt may be better suited for an impact crusher.
  • Desired output size 
    Fill material often requires 2–4 inch aggregate.
  • Mobility needs 
    Tow‑behind units are ideal for rural or uneven terrain.
  • Budget 
    Rental rates range from 500 to 1,500 dollars per day depending on size and region.

Practical Example
A landowner attempting to shrink a pond may have 200 loads of demolition concrete available. If each load averages 10 tons, that is roughly 2,000 tons of material. Crushing this on site could yield enough fill to complete the project without purchasing additional dirt. In some cases, crushed concrete can even be traded for clean fill, creating a mutually beneficial exchange with local contractors.

Operational Tips and Solutions
1. Pre‑Sorting Material 
Remove large steel pieces before feeding the crusher. Most micro crushers can handle light rebar, but tangled steel slows production.
2. Moisture Control 
Wet concrete reduces dust but may clog screens. Light misting is ideal.
3. Consistent Feeding 
A steady flow improves efficiency. Using a small excavator or skid steer with a grapple bucket is recommended.
4. Maintenance Routine
  • Check jaw plates daily
  • Grease bearings
  • Inspect belts
  • Monitor engine temperature
5. Safety Practices
  • Maintain a clear perimeter
  • Use hearing and eye protection
  • Keep bystanders away from discharge areas

Stories from the Field
The Farmer Who Built a Road from Demolition Debris
In rural Pennsylvania, a farmer inherited a pile of broken concrete from a demolished barn. Instead of paying for disposal, he rented a micro crusher for a week. The machine processed 300 tons of concrete, which he used to build a half‑mile access road to his fields. The project saved him nearly 12,000 dollars compared to purchasing gravel.
A Contractor’s Unexpected Revenue Stream
A small contractor in Michigan began crushing leftover concrete from residential demolition jobs. Within a year, he was selling recycled aggregate to landscapers and utility companies. What started as a cost‑saving measure turned into a profitable side business, generating more than 40,000 dollars annually.

Industry Trends and Future Outlook
Demand for small‑scale crushing equipment continues to grow due to:
  • Urban redevelopment
  • Infrastructure expansion
  • Environmental regulations
  • Rising material costs
Manufacturers are responding with:
  • Electric‑powered crushers
  • Hybrid systems
  • Noise‑reduction technology
  • Improved dust suppression
Some companies are even developing AI‑assisted control systems that adjust jaw pressure and feed rate automatically based on material density.

Conclusion
Small‑scale crushing projects offer a practical, economical, and environmentally responsible solution for handling concrete and demolition debris. Whether filling a pond, building a road, or preparing a construction site, compact crushers transform waste into valuable material. With modern equipment becoming more efficient and accessible, on‑site crushing is no longer reserved for large contractors—it is now a realistic option for landowners, farmers, and small businesses alike.
