Southwest Mill Supply Company is a historic manufacturer and supplier focused on hammermill replacement parts and wear components. Founded in the early 1920s by Mr. A.D. Swartz, SMS began as a basement operation producing hammers for agricultural-related customers and evolved into a full-service replacement parts supplier by the early 1930s, expanding to include screens to complement hammers. The company later relocated to its long-standing Kansas City facility, with the current site established by 1994 as part of ongoing growth. Southwest Mill Supply emphasizes a strong heritage of quality and performance, leveraging capabilities in technology, manufacturing, engineering support, and distribution to deliver smart, cost-effective solutions that outperform competitors. SMS highlights its innovation in wear parts design, employing advanced welding technology to maximize wear life and offering high-alloy steel options to meet demanding application conditions. The product range includes standard to premium custom hammers, screens, rods, spacers, and other hammermill accessories, underscoring SMS’s role as a comprehensive source for hammermill needs. The company’s shop floor capabilities focus on durable wear part manufacturing, with an emphasis on material quality and precise workmanship to ensure reliable performance in harsh processing environments. SMS describes itself as a partner to customers seeking durable, high-performance components, backed by engineering support and a distribution network designed to deliver prompt service and delivery across its markets. The business operates from 232 North Baltimore Ave, Kansas City, MO, and maintains toll-free and local partnerships for customer accessibility, with a primary contact channel via sales@swmill.com and phone support at 1-800-899-4072.
