N.Mac® Inline Twin Shaft Grinder
Full service in place for grinding impurities in pipeline installations
Protect your system from impurities: The N.Mac® inline twin shaft grinder crushes fragmenting large and solid particles in liquid product and includes the FSIP® concept (Full Service-in-Place). It is ideal for various applications, from wastewater treatment and substrates to food and fruit residues for biogas plants.
The inline housing design allows installation in pipeline systems to protect the downstream equipment, such as your pumps. Despite the pipeline installation, this grinder offers you the proven FSIP® concept due to its innovative design. You can carry out complete maintenance without removing it from the pipeline, saving you time and the associated costs. Depending on the desired crushing degree, you can choose from numerous tooth combinations. The different blade designs with three to eleven teeth can be easily replaced. You can determine the degree of shredding yourself. In addition, there are different blade blocks with unique geometries for optimal fragmentation of solids. If a blockage should occur, an optional control system with reversal of the direction of rotation offers you a remedy. This allows you to easily remove blockages in the cutting devices without having to dismantle the grinder.

Depending on the desired crushing degree, you can choose from numerous tooth combinations. The different blade designs with three to eleven teeth can be easily replaced. This means you can determine the degree of shredding yourself. In addition, there are different blade blocks with unique geometry for optimal comminution of solids. If a blockage should nevertheless occur, an optional control system with reversal of the direction of rotation offers you a remedy. This allows you to easily remove blockages in the cutting devices without having to dismantle the shredder.

FAQ grinding systems
Grinding systems are used to shred coarse solids, impurities or fibrous components before or within pump systems. They reliably protect pumps and plant technology from blockages, damage, and unplanned downtime.
Grinding systems can process a wide range of solids, including fibrous materials, plastics, textiles, organic components, wood, hygiene articles and lumps in sludge and wastewater. The exact suitability depends on the system’s design.
Grinders can be installed upstream of the pump, in the suction line, or directly in the pipes. The optimal positioning depends on the process conditions, the media composition, and the pump type.
Grinding systems are robust and designed for reliable continuous operation. Maintenance requirements are low and primarily consist of regular visual inspections and replacement of wear parts, depending on the medium and operating conditions.
All relevant original spare parts for grinding systems from NETZSCH Pumps & Systems are available, including cutting tools, cutter rings, knives, seals, and other wear-related components. The spare parts are precisely matched to the system design and ensure reliable, safe operation.
NETZSCH Pumps & Systems supports you from consultation and design to the integration of the proper grinding system. Based on your process data, we develop a solution that is optimally tailored to your application.
