How Does Mobile Crushing Work? A Complete Guide
Mobile crushing is revolutionizing how construction and demolition projects handle concrete waste. Instead of hauling thousands of tons of concrete to distant recycling facilities or landfills, mobile crushing brings the crusher to your site, processing material on-site and creating immediate reuse opportunities.
What is Mobile Crushing?
Mobile crushing uses self-contained, track-mounted crushing equipment that can be transported to your job site, set up quickly, and process concrete, asphalt, and masonry materials into reusable aggregate—all without leaving your property.
At Inland Concrete Recycling, we use a Rubble Master RM 80 mobile impact crusher, one of the most advanced and efficient mobile crushers available for demolition and recycling applications.
The Rubble Master RM 80: Our Equipment
Key Specifications
- Capacity: 150-200 tons per hour processing rate (depending on material type)
- Power: Self-contained diesel engine (no external power required)
- Mobility: Rubber tracks for on-site movement and positioning
- Output size: Adjustable from 3/4" up to 4"
- Features:
- Overhead magnetic separator for automatic rebar removal
- Can process concrete with rebar (extra charges apply)
- Integrated dust suppression system
- Remote control operation for safety and precision
- Compact footprint suitable for confined job sites
Why the RM 80?
The Rubble Master RM 80 is specifically designed for concrete recycling:
- Impact crushing technology: Produces better-shaped aggregate compared to jaw crushers
- High reduction ratio: Processes large concrete pieces (up to 24" feed size) into fine aggregate
- Fuel efficiency: Diesel-electric hybrid system reduces operating costs
- Low noise: Suitable for urban job sites with noise restrictions
- Minimal dust: Integrated water spray system for dust suppression
The Mobile Crushing Process: Step-by-Step
1. Project Assessment and Planning
Before the crusher arrives, we:
- Evaluate your site: Access routes, working area, proximity to neighbors
- Estimate volume: Calculate tonnage to determine project timeline
- Identify material types: Concrete, asphalt, brick, mixed demolition waste
- Plan logistics: Equipment positioning, material stockpile locations, product reuse strategy
Minimum project size: 200 tons (approximately 6-8 tri-axle truck loads)
2. Equipment Mobilization
The RM 80 crusher is transported to your site on a lowboy trailer:
- Transport weight: ~26 tons
- Setup time: 2-4 hours depending on site conditions
- Working area required: Minimum 100' x 50' clear zone
- Access requirements: Can navigate most construction site access roads
3. Site Setup
Once on-site, we:
- Position the crusher: Optimal placement for material feed and product stockpiling
- Configure output settings: Adjust crusher gap for desired aggregate size
- Set up dust suppression: Connect water source or fill on-board tank
- Establish safety zone: Barrier tape and signage around crushing area
- Conduct safety briefing: Review procedures with on-site personnel
4. Material Feeding
Concrete is fed into the crusher using:
- Excavators: Most common method—excavator loads material into hopper
- Wheel loaders: For larger projects with pre-staged material piles
- Skid steers: Suitable for smaller, confined projects
Feed size: Material up to 24 inches can be processed, but breaking larger pieces with a hydraulic breaker speeds up crushing
5. The Crushing Process
Inside the RM 80, material undergoes several stages:
- Pre-screening: Smaller material bypasses the crusher, improving efficiency
- Impact crushing: High-speed rotor impacts concrete against wear plates, shattering it into aggregate
- Magnetic separation: Overhead electromagnet continuously removes rebar and wire mesh
- Sizing screen: Adjustable screen ensures consistent output size
- Discharge: Finished aggregate is conveyed onto stockpile or directly into trucks
Processing rate: 150-200 tons per hour depending on material hardness and moisture content
6. Quality Control
Throughout crushing, we monitor:
- Output size: Ensuring aggregate meets specification (typically 3/4" road base or 3" minus)
- Contamination: Removing any non-conforming material (wood, plastic, excessive fines)
- Metal separation: Verifying magnetic separator is capturing all rebar
- Dust control: Adjusting water spray to minimize airborne dust
7. Product Stockpiling
Crushed aggregate is stockpiled in designated areas:
- Immediate reuse: Load directly into trucks for base course, fill, or drainage applications
- On-site storage: Stockpile for future use in landscaping, roads, or site development
- Off-site sale: Transport finished product to other projects (less common, as on-site reuse is more cost-effective)
Cost Savings with Mobile Crushing
Mobile crushing delivers dramatic cost savings compared to traditional haul-away disposal:
Traditional Disposal Costs (1,000-ton project example)
- Loading: $3,000 (excavator time)
- Hauling: $25,000-35,000 (30-40 truck loads @ $750-900/load)
- Tipping fees: $120,000-180,000 (1,000 tons @ $120-180/ton)
- Total: $148,000-218,000
Mobile Crushing Costs (same project)
- Crusher mobilization: $2,000-4,000
- Processing: $15,000-25,000 (1,000 tons @ $15-25/ton)
- Excavator time (if not already on-site): $3,000
- Total: $20,000-32,000
Net savings: $116,000-186,000 (80-85% reduction in costs)
Additional Benefits
Beyond direct cost savings:
- Eliminate hauling emissions: No truck traffic reduces project carbon footprint
- Reuse crushed material on-site: Replaces purchased aggregate ($20-40/ton value)
- Scrap metal value: Separated rebar has scrap value ($100-200/ton)
- Faster project completion: No waiting for haul trucks or coordinating dump runs
- Reduce neighborhood disruption: Far fewer trucks entering and leaving the site
Ideal Projects for Mobile Crushing
Mobile crushing is most cost-effective for:
Commercial Demolition
- Office building demolition
- Retail center redevelopment
- Industrial facility decommissioning
- Warehouse and manufacturing plant removal
Infrastructure Projects
- Parking structure demolition
- Bridge deck replacement
- Road reconstruction
- Runway and taxiway removal
Residential Development
- Subdivision development (crush existing pavement for new road base)
- Estate home construction (reuse demolished foundation as site fill)
- Multi-family construction (process demo waste on-site)
Municipal Projects
- School demolition and reconstruction
- Park and recreation facility upgrades
- Water/sewer infrastructure replacement
- Sidewalk and curb reconstruction
Minimum Project Size: Why 200 Tons?
Our 200-ton minimum exists for practical and economic reasons:
- Mobilization costs: Transporting the crusher requires specialized equipment and labor
- Setup time: 2-4 hours to position, configure, and test equipment
- Demobilization: 2-3 hours to clean, secure, and remove crusher
- Operator costs: Certified operator wages and benefits
For projects under 200 tons (roughly equivalent to a residential driveway or small patio), drop-off recycling at our Langley facility is more cost-effective. You save on mobilization while still benefiting from recycling economics.

Frequently Asked Questions
Q: How long does crushing take? A: At 150-200 tons per hour, a 200-ton project typically takes less than a day (including setup/teardown). Larger projects are scheduled over multiple days or weeks.
Q: Can you crush in winter? A: Yes, though extreme cold can reduce efficiency. Frozen material requires longer processing time.
Q: What about dust and noise? A: We use water suppression for dust. Noise levels are typically 85-95 dBA at the crusher, acceptable for industrial/commercial zones. Residential projects may require specific hours of operation.
Q: Do you provide the excavator? A: No, crushing pricing assumes you provide a loader/excavator to feed material. We can coordinate rental if needed.
Q: Can I be present during crushing? A: Yes, but you must remain outside the safety zone. Our operator will coordinate access for site managers or inspectors.
Conclusion
Mobile crushing transforms concrete demolition from a costly disposal problem into an economic and environmental opportunity. By processing material on-site, you save money, reduce environmental impact, and create immediate reuse potential—all while keeping your project on schedule.
