Hammer mill

Hammer mill refiner for wood and biomass processing

The GCM-REF hammer mill refiner is an electromechanical equipment, designed to reduce the dimension of the previously calibrated dried material (G20-G30), resulting in a very thin product, suitable for carrying out subsequent industrial operations or appropriate for other specific requirements. The shredding device is comprised of a directly attached rotor dynamically balanced, equipped with moving hammers, that undergo specific thermal treatment, designed to guarantee an adequate hardness and resistance to wear; if needed, hammers can also be provided with a wear-resistant welded overlay. The hammer mill can achieve an extremely high volumetric reduction of the material, controlled by an interchangeable calibrating grid, placed at the bottom of the shredding chamber. Grid characteristics may vary depending on request and intended use, according to different parameters: material, drilling, size and thickness. Our hammer mill can operate efficiently on tasks with various materials like wood, feed, fertilizer, paper, etc. GCM INDUSTRIE also provides high quality support customer, maintenance service and provision of spare parts subjected to normal wear or inevitable degradation such as grids, hammers, bearings etc., ensuring the adequacy of supply within global market requirements.
