M-900 Crusher Bucket – On-Site Construction Waste Processing

Project Background
On a building demolition site, large amounts of construction waste accumulated rapidly — concrete slabs, bricks, reinforced concrete blocks, and mixed rubble. Traditional disposal required:
- Hiring trucks to haul waste off-site
- Paying landfill or disposal fees
- Purchasing new aggregate for backfill and road base
These steps significantly increased project costs and extended the construction timeline.
The contractor needed a solution to process the waste **on-site**, eliminate transport costs, and turn demolition debris into usable material.
The Solution: JM-900 Crusher Bucket
The JM-900 crusher bucket was mounted on a Sumitomo SH200 excavator (20-ton class), transforming the machine into a mobile crushing station.
JM-900 Key Specifications:
| Parameter | Specification |
|---|---|
| Compatible Excavator | 20–30 tons |
| Bucket Capacity | 0.9 m³ |
| Open Width | 920 mm |
| Open Height | 520 mm |
| Output Size Range | 15–150 mm (adjustable) |
| Weight | 4,200 kg |
| Operating Pressure | 150–320 bar |
| Flow Rate | 150–220 L/min |

JM-900 Core Advantages
- Adjustable output (15–150 mm) – quickly switch between fine aggregate and coarse base material
- High durability – Hardox wear-resistant steel frame + Mn20Cr2 alloy jaw plates
- Reversible jaw plates – upper/lower interchangeable, single plate can be turned forward/backward – triple service life
- Replaceable side wear plates – easy maintenance, lower operating costs
- High inertia flywheel – ensures stable and efficient crushing performance
- German Rexroth hydraulic motor – reliable power and precise control
- Quick installation – mounts directly without excavator modification
Workflow
Step 1: Material Collection
The excavator gathered concrete blocks, brick rubble, and mixed construction waste from the demolition site.
Step 2: On-Site Crushing with JM-900
The JM-900 processed the construction waste directly on-site. Concrete, brick, and mixed debris were crushed efficiently. The crushing action also helped separate rebar from concrete material.
Step 3: Adjust Output Size
The output size was set to 30–50 mm, producing aggregate suitable for road base and backfill applications. Adjustment is quick and requires no special tools.
Step 4: Reuse On-Site
The crushed material was immediately used for:
- Site backfill and foundation leveling
- Temporary road base construction
- Recycled aggregate for new building foundations
Results and Benefits
| Item | Traditional Method | With JM-900 |
|---|---|---|
| Waste Hauling | Required (multiple truck trips) | Not required |
| Landfill Fees | High | Zero |
| Purchased Aggregate | Required | Not required |
| Project Timeline | Extended by transport delays | Significantly shorter |
| Equipment | Excavator + trucks + loader | Excavator + JM-900 only |

What the Contractor Saved:
- Transportation costs – no trucking fees for waste removal
- Landfill disposal fees – zero waste sent to landfill
- Material purchase costs – recycled aggregate replaced purchased stone
- Labor costs – reduced handling, loading, and waiting time
