Gericke, a long-established specialist in size reduction and particle processing, continues to refine its offering of milling and granulation equipment under the “nibbler” brand. Drawing on extensive industry experience, Gericke’s experts provide tailored advice on the optimal screen or shredder configuration based on specific product characteristics and processing goals.

The latest generation of Gericke nibblers, the GNB series, introduces new screen options designed to address a broader range of material types and production challenges. These machines are used to break down lumps, agglomerates, filter cakes, frozen materials, and rework into uniform, processable grain sizes.

Choosing the right screen is critical. For brittle materials, where minimising fines is essential, different screen inserts are required compared to those for tough, greasy or moist materials that risk clogging the mesh. For example, dried but hygroscopic products such as those from a belt dryer require screen designs that maintain product integrity and throughput while reducing fines.

Tougher materials like cocoa, which exert higher mechanical stress on the equipment, demand reinforced graters capable of withstanding these loads. In many deagglomeration scenarios, the selected screen may not match the final desired particle size, but instead prepares the product for further processing with consistent results.

Gericke offers both loan units and access to global test centres, allowing users to determine the optimal configuration for their application. This flexibility ensures customers can balance throughput, product quality and machine longevity with confidence.
