A CRUSHER THAT FITS WHERE THE WORK IS

At first glance, a crusher bucket might seem like an unlikely choice for a large-scale quarry.

After all, quarries are associated with massive equipment, high-capacity crushers, and fleets of haul trucks.

But the BF135.8 is not designed to replace every piece of a conventional crushing circuit. Its value is in adding another level of flexibility to the operation.

Designed for excavators weighing between 94,800 lbs and 176,370 lbs, the BF135.8 features a 2.35 cu yd load capacity and can achieve production of up to 115 cu yd, depending on material and operating conditions.

In other words, this is not a “small machine trying to do a big machine’s job.”

It is a large excavator attachment designed to put crushing directly at the point of excavation.

WHY MOVE THE MATERIAL TWICE?

For quarry operators, every additional movement of material can mean another machine, another operator, another fuel cost, and another handling step.

The BF135.8 offers a different proposition: process material where the excavator is already working.

That can be particularly interesting when material needs to be reduced before moving further through the site, when access is difficult, or when material generated during quarrying can be repurposed rather than treated simply as waste.

MB Crusher has highlighted applications where quarry material and mining waste can be processed directly on site and reused for haul roads, road bases, backfill, and other quarry requirements.

The result is a shift in thinking:

The excavator is no longer only digging and loading. It can become part of the crushing process.

BIGGER DOES NOT ALWAYS MEAN MORE EFFICIENT

One of the natural questions around a bucket crusher is volume.

Can a bucket really handle the demands of a quarry?

The answer depends on the job — and that is precisely where the business case becomes interesting.

A bucket crusher does not necessarily have to compete with the highest-capacity plant in a quarry. Instead, it can address the jobs where a full crushing plant is not the most efficient answer.

That could mean processing material in a specific area of the quarry, reducing oversize, managing excavated material, producing material for internal roads or backfill, or dealing with material in locations where moving it to a central plant adds unnecessary handling.

In these situations, the value is not simply how much material the bucket can process per hour. It is how many steps it can eliminate from the overall process.

TURNING QUARRY MATERIAL INTO A RESOURCE

Mining and quarrying inevitably generate material that needs to be managed.

But material that might previously have been considered waste can sometimes become a useful resource.

MB Crusher points to applications where crushed material can be reused directly within the quarry — including haul-road maintenance, subgrade construction, and backfilling — reducing the need to purchase, transport, or move additional aggregate.

For an operator, that creates a straightforward equation:

Less material movement + Fewer handling steps + Greater site material usage = Reduced operating costs and because the crusher bucket is attached to an excavator, the crushing capability moves with the machine.

MB Crusher’s approach is ultimately about changing the role of equipment already working on the jobsite.

The excavator remains an excavator — but with the right attachment, it can also become a mobile crushing solution.

So perhaps the question isn’t:
“Can a bucket crusher handle a quarry?”

Perhaps the better question is:
“How much of the quarry operation can be made more efficient when the crusher comes to the material instead of the material going to the crusher?”

That is the opportunity MB Crusher is putting to the test — one bucket, one excavator, and one quarry at a time
