Deagglomerator for consistent particle size reduction
Struggling with inconsistent particle sizes or unwanted lumps in your production line? This versatile equipment ensures optimal size reduction and deagglomeration, delivering consistent granule quality across a wide range of solid and slurry products.

Reduces, Deagglomerates, and Calibrates Material Size
The Gericke Nibbler GNB 530 is an essential piece of equipment for efficient deagglomeration, size reduction, and size calibration across a broad range of industries, including food, pharmaceuticals, and chemicals. Utilizing a cutting action with low rotational speed, it minimizes heat generation and prevents fines while maintaining consistent particle size. Capable of handling materials from powders to slurries, it is suitable for applications from cornflakes to chemical catalysts. With processing capacities ranging from less than 10 kg/h up to 50,000 kg/h, the GNB 530 offers customizable screen sizes (1 mm to 25 mm) and a hygienic design conforming to EHEDG standards. The system facilitates easy maintenance with tool-free access and features options for ATEX compliance, ensuring safe operation in diverse environments. Moreover, its energy-efficient design contributes to lower operational costs, making it a smart investment for integrated production lines.
