Introduction to the Börger OrbitGrinder Macerator
In the ever-evolving landscape of biogas and wastewater treatment facilities, the efficient processing of solid materials remains a critical challenge for operators and engineers. The introduction of the Börger OrbitGrinder Macerator marks a significant technological advancement in addressing these challenges, offering an innovative solution that combines superior performance with operational reliability.
At its core, this cutting-edge macerator represents a fundamental rethinking of traditional solids reduction technology. While conventional macerators have long struggled with their wear patterns and consistency of particle size reduction, the OrbitGrinder's revolutionary star-shaped cutting system delivers unprecedented uniformity in processing performance. This innovation directly addresses the primary concerns of process engineers: equipment protection, operational efficiency, and maintenance optimization.
Press Release
Star-shape blade design ready to macerate solids at wastewater and biogas plants
Borger has launched a new cutting-basket macerator that helps protect wastewater/biogas pumps and downstream equipment by consistently mashing solids.
Designed with pivoted cutting blades that adjust automatically, the OrbitGrinder operates at an even cutting speed, with its cutting basket’s blades arranged in a special star shape to maximise shredding.
Not only is flow through the OrbitGrinder’s cutting basket homogenous, but the baffle plate also ensures that the suction force of the pump is evenly distributed.
Compared to standard, round perforated disks, the circumferential speed of the Orbitgrinder’s blades is the same in every cutting point, delivering uniform macerating results.
Macerators with round perforated disks also typically see excessive wear of the cutting plates’ outer edge, whereas the OrbitGrinder’s design and durability provides a significantly prolonged service life.
The OrbitGrinder’s simple inlet and outlet can be positioned at different angles to suit, and with the top and bottom parts connected by standard screws, this highly effective new macerator can be easily integrated into any existing system.
As with all proven Borger equipment, the Maintenance-In-Place design makes servicing much easier than laborious alternatives. The OrbitGrinder benefits from a gas strut assisted quick-release cover.
Impurities are sent into the debris collector.
