Frequently Asked Questions About Bucket Crushers
What does a bucket crusher do?
A bucket crusher is an excavator or loader attachment that crushes concrete, brick, rock and demolition rubble directly on site, producing reusable aggregate for backfill, road base and construction fill. This eliminates the cost and time of trucking waste to a crusher plant.
Which machines can a bucket crusher attach to?
MB Crusher bucket crushers attach to excavators and wheel loaders. The range covers host machines from 2 to 70 tons. MCM Group can advise on the correct model for your excavator based on operating weight and hydraulic flow.
Are bucket crushers available with after-sales support in South Africa?
Yes. MCM Group is the official MB Crusher distributor in South Africa. We stock genuine jaw plates, bearings and wear parts, and provide technical support from our branches in Cape Town, George, Gauteng and Bloemfontein.
What materials can a bucket crusher process?
MB Crusher bucket crushers handle reinforced concrete, natural stone, brick, asphalt and demolition waste. The output size is adjustable via the jaw setting, typically producing aggregate from 30 mm to 100 mm depending on the model and setting.
On South African construction and demolition projects, bucket crushers generate significant savings by eliminating the trucking and tipping fees associated with demolition waste. When an operator crushes concrete rubble in the excavator bucket and immediately reuses the material as site fill or road base, the project avoids purchasing imported aggregate, avoids paying tipping fees at a waste facility, and reduces truck movements — cutting both cost and programme duration.
MB Crusher bucket crushers (the BF range) are available for excavators from 6 to 150 tonnes. The crusher is driven by the excavator's existing auxiliary hydraulic circuit — no separate power unit or generator is required. Material is fed into the bucket opening, crushed by the oscillating jaw against a fixed wear plate, and exits through the bottom of the bucket as aggregate of the size set by the jaw gap.
Jaw gap is adjustable to produce different aggregate sizes. A small jaw gap produces fine material (20—50 mm) suited to road base and pavement layers. A larger gap produces coarser aggregate (80—150 mm) for bulk fill and drainage applications. Adjusting the jaw gap takes approximately 10—15 minutes without specialised tools.
