Plastic recycling innovations also affect filtration after size reduction. EREMA announced the Laserfilter LF 812 in October 2025. For a plant, the news is useful when it relates to contamination, melt quality and maintenance.
Which blades and wear parts are involved in crushing, granulating, washing, drying, compacting and pelletizing plastic.
Functions and wear of rotor blades, stator, blade holder and hardware in single-shaft shredders for recycling.
Serrated packaging knives must repeatably cut material that can vary in thickness, structure and behavior.
Irregular chaff can indicate a problem in cutting, but also changes in feeding, cooling or state of the polymer. Before replacing pelletizer blades, it is advisable to record the defect and relate it to the production conditions.
Scrap shear blades must cut materials of varying geometry and thickness.
Industrial circular knives are used in longitudinal cutting operations of continuous materials.
Practical criteria for deciding whether a mill, crusher or guillotine blade can be resharpened or must be manufactured anew.
How to choose drilling diameter, thickness, material and geometry of screens for granulating and crushing mills.
Mill and crusher screens receive abrasion, impacts and assembly efforts. A correct replacement combines material, perforation, thickness and support geometry. Choosing solely by hole size can alter the operation of the equipment.
