Many raw materials tend to create lumps during transporation or storage. The product loses his ability to be processed easily. Pneumatic conveying systems may get disturbed, feeder deliver inaccurate recipes and mixers cannot distribute the ingredients to a homogene concentration in the mixing chamber. To reduce the size of the agglomerates, Gericke offers a size reductor (Nibbler) for the reliable and quick particle size reduction.
Gericke Nibblers treat the raw material gently and reduce blocs, lumps and agglomerates. Rotating paddles push the material through a screen. The rotation and angle of the paddles sweep the product against the serrated screen with the reduced particles passing through the holes. Size reduction is achieved by a cutting action (not grinding) and the breaking effect of brittle materials. The Nibbler works with a low peripheral tip speed avoiding the heating up of the products. Gericke Nibblers are available for the integration into different ATEX zones and are used after sac tipping stations, container or Big-Bag emptying stations. Another field of application are recycling loops or melting applications e.g. of chocolate blocs, large surface areas reduce the melting time and energy. Nibblers are manufactured in different sizes (inlet sections from 200x200 mm up to 300x800 mm). Gericke produces also versions for Pharmaceutical industries, this Nibblers are completely dismountable and apt for Autoclave sterilisation.
