Our products are primarily used for overlaying severely worn or cutting workpieces in industries such as petroleum, mining, coal mining, geology, and construction. Applications include mill shoes, grinding shoes, centralizers, reamers, drill pipe joints, core drill bits, pile driver bits, spiral drill bits, coal mining drill bit repairs, as well as mixing and crushing equipment in steel mills, sugar mills, paper mills, construction, and refractory material plants. They are ideal for repairing various wear-prone components, delivering excellent results. For many years, our company has specialized in the research and development of wear-resistant materials for industries such as mining, metallurgy, building materials, and chemicals. As a high-tech enterprise, we possess advanced precision casting production lines and sand casting capabilities. Utilizing medium-frequency melting, infrared carbon-sulfur analysis, and state-of-the-art production and testing equipment, we ensure the accuracy and reliability of chemical composition and mechanical properties. Our primary focus is the production of various crusher hammers. By incorporating the strengths of diverse technologies and drawing on years of practical experience, we have developed a comprehensive approach tailored to different ores and specific requirements for raw materials and heat treatment. We are a professional, dedicated, and reputable manufacturer committed to quality service. Particularly, our dual-alloy high-chromium composite hammers combine wear resistance with high strength and toughness, pioneering a new application field for wear-resistant cast iron. They are the ideal choice for wear-resistant components under high-stress impact conditions, both domestically and internationally.
