Engineered for the robust SDMIX KT30 series concrete mixers, these high-chomium alloy blades are manufactured to deliver exceptional performance under extreme abrasion conditions. Products using our advanced lost-foam casting and vertical flaskless molding production lines, each blade achieves a material density exceeding 99.7%, which eliminates micro-porosity and ensures outstanding structural intergrity. This precision manufacturing process, certified under ISO9001 quality management systems, guarantees consistent performance and an extended survice life, reliable handing over 300,000 cubic meters of concrete.
The balde are crafted from a proprietary high chromium alloy refined in medium-frequency induction furnaces. this results in a superior metallographic structure with a uniform distribution of hard carbides, yielding a surface hardness of 58-65 HRC. Independent verification confirms that this material composition provides a tensile strength of 450N/mm² and an impact toughness of ≥8 J/cm²,ensuring remarkable resistance to fracture and deformation under heavy-impact conditions. The blade geometry is further optimized through digital simulation to reduce stress concentration, enhancing fatigue resistance and contributing to servide life that 50% longer than that of conventional blades.
These blades are desigend for perfect compatiblity with the SDMIX KT30 mixer series, ensuring seamless integration and optimal mixing efficiency. The installation adjustment is critical, and our blades are precision-engineered to maintain the recommended 2-3mm gap with the liner plates, preventing material clogging and reducing wear. Backed by our four decades of metallurgical expertise, we provide comprehensive technical support to help you maximize operational uptime and reduce the total cost of ownership.
