Engineered specifically for SDMIX KT30 series concrete mixers, our impact-resistant composite liners are designed to withstand the most demanding conditions where abrasion and impact forces combine to accelerate wear. Manufactured through our ISO-9001-certified production system, each liner undergoes precision lost-foam casting and vertical molding process, achieving exceptional material purity with density rating of 99.8% that eliminate structural weaknesses and ensure consistent performance under extreme operational stress.
The liners features our innovative composite material system, combining a high-chromium base alloy with strategic additions of tungsten and vanadium, meticulously refined in medium-frequency induction furnaces. This creates an optimized miscrostructure with graduated hardness from 60-66 HRC, providing balanced protection against both impact demage and abrasive wear. Independent laboratory testing confirms these liners withstand over 350,000 cubic meters of concrete mixing while maintaining dimensional stability-reprasenting a 58% service life improvement compared to conventional liners.
Our digital manufacturing platform ensures orecise dimensional control, with each liner CNC-machined ±0.15mm tolerance for perfect KT30 series compatibility. The liner geometry is optimmized through finite element analysis to distribute impact forces across the surface, reducing localized stress by 52% while maintaining optimal mixing efficiency. the specialized wave-pattern surface design reduces material adhesion by 65%, preventing concrete bulidup and ensuring consistent mixing performance throughout the operational lifespan.
The advanced metallographic structure delivers exceptional machanical properties including 485N/mm² tensile strength and impact toughness of 8.6 J/cm², ensuring reliable performance under heavy impact loads. Backed by comprehensive technical documentationand respomnsive customer support, these liners are engineered for straightforward installation and long-term reliability indemanding concrete production enviroment.
