Low maintenance by design. The Heavy-duty Roll Breaker is designed to operate at lower speed that does not have the same wear impact as a Hammer crusher. The crushing segments has a wear lifetime of at least 3 years and have been known to last more than 5 years, thereby a low maintenance.

Crushers are machines designed to reduce large materials, typically rocks, concrete or asphalt, into smaller materials for purposes of sizing, recycling, reduction, and more. These crushers are typically found in quarries, mines, recycling facilities, and other locations where raw material or demolition materials are found.

The action of a roll crusher, compared to the other crushers, is amenable to a level of analysis. Consider a spherical particle of radius r, ... The heavy duty crusher diameters range between 900 and 1000 mm with face length between 300 and 610 mm. In general, the spring pressures of the heavy duty rolls range between 7 and 60 kg/m. ...
