Product Showcase: BF90.3 S4 Crusher Bucket

Quick answer

The MB BF90.3 S4 is a crusher bucket that is designed to fit onto an excavator and crush concrete, rubble and rock on site into reusable aggregate using a powerful crushing jaw.

On-site crushing provides a fast return, because reusing crushed material allows you to cut the transport, landfill and aggregate costs on every demolition or earthworks job.

A crusher bucket is a versatile attachment, because it offers mobile crushing wherever the excavator works, so matching one involves checking your carrier weight and hydraulic flow.

This showcase describes the MB BF90.3 S4 crusher bucket and helps a South African contractor see how on-site crushing reduces cost and waste.

A crusher bucket is an attachment that is designed to turn demolition waste into usable product on site, and this provides a contractor with aggregate for backfill or sub-base without paying to truck rubble away and buy new stone.

Matching the BF90.3 to an excavator involves checking the carrier weight and the hydraulic flow, because the bucket is designed to run on a correctly sized machine that provides the pressure the crushing jaw needs.

Frequently Asked Questions

What size excavator do I need to run the BF90.3 crusher bucket?
The BF90.3 must be matched to a correctly sized carrier — both the machine’s operating weight and its hydraulic flow and pressure matter, so it suits larger excavators rather than minis. MCM checks your machine’s weight and hydraulics before recommending the right crusher bucket so the jaw gets the power it needs.
What materials can the BF90.3 crush?
It crushes concrete, demolition rubble, natural rock, asphalt and other inert material directly on site, turning waste into reusable aggregate for backfill or sub-base.
How does on-site crushing actually save money?
Instead of trucking rubble to landfill and buying in new stone, you crush and reuse the material where the excavator is working. That cuts transport, tipping and aggregate costs on every demolition or earthworks job — often paying the attachment back quickly on a busy site.
How much maintenance does the crusher bucket need?
The BF90.3 has an integrated centralized greasing system that reduces routine service time. Beyond regular greasing and checking the jaw wear parts, upkeep is straightforward, and MCM Group supplies genuine parts as the MB Crusher distributor in South Africa.
Is the BF90.3 suitable for recycling concrete in South Africa?
Yes. It is a proven, popular choice for demolition and civil contractors who want mobile crushing wherever the machine goes — ideal for recycling concrete and rubble on South African sites rather than hauling it away.
