Jaw-action bucket crushers

Italian-based manufacturer MB S.p.a. offers four basic models of jaw-action bucket crushers, suitable for excavators from 8-ton to over 28-ton classes. Crushed material can be recycled directly on site, and all that is needed is a standard excavator in order to work efficiently. These tools are ideal in demolition and various other applications in construction, as well as for land reclamation, quarrying and mining.

The bucket crusher is a hydraulic tool, designed from traditional jaw crusher technology. Unlike a conventional crusher however, these units are operated by the hydraulic power provided by the carrier. Units allow operators to pick up rock and various types of materials to be crushed, and then pile it onto trucks or use it for back-filling on site. The four models (BF 60.1, BF 70.2, BF 90.3 and BF 120.4) weigh from 1.5 to 4.9 tonnes; crusher jaw openings range from 60 x 45 cm to 120 x 45 cm; and bucket capacities are from 0.5 m³ to 1 m³.

Output material piece size is adjustable from between 20 and 120 mm, depending on the model, while average hourly production is between 9.1 and 50 m³ (depending on the model and required product size).

Additionally, a new iron separator system provides an efficient way to handle the separation of ferrous metals from crushed inert materials. Available for all MB bucket crusher models, this device is composed of a 250 kg magnet, magnet support and installation kit.
