RYOHSHIN's Coarse Shredder series, including 2-shaft, 4-shaft, and FR models, are engineered for creating a sustainable circular society by efficiently processing diverse materials. The 2-shaft shredders feature robust direct-drive systems with patented ACLS™ cutter locking and SSP™ severe shock protection, providing high-torque shearing for materials like metal-contaminated waste, carpets, and tires, with capacities from 0.5-70 tons/hour. Technical details include labyrinth seals for bearing protection and cleaning fingers to prevent material wrapping. An optional SMARTFEED system for 2-shaft models enhances processing of difficult materials like ropes and fishing nets by automatically adjusting shaft speed based on load, optimizing efficiency and reducing energy consumption. The 4-shaft shredders are designed for producing fine, uniform output (typically 19-203mm) from various materials, incorporating a self-cleaning design, removable screens for precise size control, and reversible cutters. The FR series coarse shredders, equipped with innovative touch panel controls and hydraulic motors, handle general, bulky, and industrial waste with high capacity, featuring robust Hardox cutters, externally mounted bearings, and easy maintenance for a wide range of applications. All shredder series prioritize durability, energy efficiency, and low noise/dust operation.
