Grinder product range extended to handle higher flowrates

| By Mary Page Bailey and Gerald Ondrey

The N.Mac twin-shaft grinder is now available in expanded sizes (photo) for flowrates up to 400 m³/h. The N.Mac is designed for breaking down a variety of different materials and is ideal for wastewater treatment, biogas and biomass plants, food processing and many other waste-handling and industrial applications. The N.Mac can be installed upstream of a pump (inline version) or above the feeding screw of a hopper pump (channel version) or in any effluent channel. The inline version of the N.Mac is available in three sizes and can handle a maximum flowrate of up to 350 m³/h. The channel version of this grinder is available in four sizes, designed for a maximum flowrate of up to 400 m³/h. For applications with even higher flowrates, several grinders can be run in parallel, additionally allowing parts of the system to be serviced during operation. Installation of several grinders in sequence allows a gradual reduction of the particle size. The N.Mac is equipped with flushed and lubricated mechanical seals for dry-running capability. — Netzsch Pumpen & Systeme GmbH, Waldkraiburg, Germany
