Concrete Mixer Wear Parts for DEX

Our Ultra-Wear-Resistant DEX Mixer Liners for DMS Series are engineered to deliver unmatched durability and performance in the most demanding concrete mixing environments. Manufactured using our state-of-the-art lost foam casting (EPC) and vertical flaskless molding production lines, these liners achieve exceptional material purity and structural integrity.

Engineered for reliability and performance, our DEX DMS Mixer Wear Parts Kit represents the pinnacle of wear resistance technology for concrete batching operations. Each component in this comprehensive set is manufactured under ISO 9001-certified processes that begin with our advanced lost-foam casting (EPC) production lines and vertical flaskless molding systems. 

Description：     Engineered as the definitive wear solution for DEX DMS-series concrete mixers, our high-chromium alloy liners are the product of two decades of metallurgical expertise and advanced manufacturing. Unlike generic liners, each plate is precision-crafted using our integrated lost-foam (EPC) casting and vertical flaskless molding lines, a process certified under ISO 9001:2015. This controlled environment eliminates traditional sand casting inconsistencies, achieving a near-theoretical density of 99.6% and virtually zero gas porosity. This foundational purity is critical, as it prevents the nucleation and propagation of micro-cracks under extreme cyclical loading, a primary failure point in competitive liners. The superior material integrity begins in our medium-frequency induction furnaces, where we meticulously melt a proprietary alloy blend of 30-33% Chromium, Molybdenum, and controlled Vanadium additives. The medium-frequency stirring action ensures a perfectly homogeneous molten metal with minimal oxidation, allowing for the precise formation of hard, wear-resistant (M7C3) carbides uniformly distributed throughout the matrix. This results in a consistent surface hardness of 63-67 HRC, providing an unparalleled barrier against the abrasive and impact forces of coarse aggregates. Digital lifecycle management is embedded in our production. Using 3D kinematic simulation, we have optimized the liner profile to match the exact material flow dynamics of the DMS mixer drum, ensuring not just a perfect physical fit but also optimized mixing efficiency and reduced power consumption. Our technical support extends beyond the sale, offering digital wear mapping and lifecycle forecasting to transform your maintenance from a reactive cost into a predictable, optimized operation. Choose a liner that doesn't just last longer but works smarter, proven to deliver a 50%+ lifespan increase and significantly lower your cost per cubic meter of concrete produced.   Wear-resistant liner Wear-resistant liner Wear-resistant liner Wear resistant Liner Wear resistant Liner Wear resistant Liner Features and Advantages   Ultra-Dense Metallurgy: Vertical flaskless molding achieves 0.2% porosity for 3.1x crack resistance Metallurgical Purity Guarantee: Our EPC and flaskless molding process achieves unprecedented material density (>99.6%), eliminating defects that lead to premature cracking and failure, ensuring structural integrity from the first to the last mix.
