Grinders and Macerators From NETZSCH

Solutions for demanding applications to ensure the prevention of pipe clogging. 

Use NETZSCH grinding systems wherever it is essential that solid matter in fluids be broken down for reliable prevention of pipe clogging and damage to downstream equipment.

The technology of the grinders

Grinders can be divided into two categories based on the different technologies. The first is represented by the technology of the M-Ovas® universal cutting plate macerator and the other is based on the technology of the N.Mac® twin shaft grinder. In the cutting plate macerator, the shreddable parts are pressed against the perforated plate by the flow or are partly drawn into the holes. More significant amounts accumulate in front of the perforated plate and are ground by the cutter head until they are flushed through the openings. This effectively protects connected units from blockages. By replacing the perforated plate, you can change the hole size and consequently the degree of shredding. The twin shaft grinder technology is suitable for particularly coarse and solid contaminants. Here, the two knife blocks grind washed-up solids such as textiles or plastic waste in liquid products. Thanks to numerous different blade combinations, you can quickly determine the degree of shredding yourself. This prevents potential clogging in the pump chamber.
