Hammerhead DM-04
Hammer crushers are categorized into single-stage hammer crushers, high-efficiency hammer crushers, sand-making machines, vertical-shaft hammer crushers, reversible hammer crushers, and ring-hammer crushers. They are among the primary equipment used in industries such as metallurgy, building materials, chemical engineering, and hydropower for the fine crushing of limestone, coal, or other brittle materials with medium hardness or lower. These crushers feature a large reduction ratio, high production capacity, and uniform product particle size.

Hammer crushers are categorized into single-stage hammer crushers, high-efficiency hammer crushers, sand-making machines, vertical-shaft hammer crushers, reversible hammer crushers, and ring-hammer crushers. They are among the primary equipment used in industries such as metallurgy, building materials, chemical engineering, and hydropower for the fine crushing of limestone, coal, or other brittle materials with medium hardness or lower. These crushers feature a large reduction ratio, high production capacity, and uniform product particle size.We can supply wear-resistant parts for various models of hammer crushers, including hammer heads for crushers, ring hammers for coal crushers, impact crusher hammers, impact crusher liners, grates, grate bars, screening plates, and other accessories. We can also manufacture products from different materials based on drawings provided by customers. Jiangxi Duma offers a complete range of hammer crusher accessories, featuring excellent wear resistance, long service life, and is a trusted choice from a major manufacturer!High-manganese steel hammerheadCast high-manganese steel and ultra-high-manganese steel (Mn13, Mn13Cr2, Mn18, Mn18Cr2), combined with advanced manufacturing processes, are used to produce high-manganese steel hammer heads, ultra-high-manganese steel hammer heads, and high-manganese alloy hammer heads that can meet the diverse service conditions of hammer crushers. This ensures optimal performance of crusher hammers, making them ideal for crushing materials such as pebbles, coal gangue, and limestone. As a result, these hammer heads have become the preferred choice among numerous cement and aggregate enterprises.Bimetallic composite hammer headEmploying a state-of-the-art composite casting process, the hammer head is made of high-chromium cast iron with excellent wear resistance, while the hammer handle is crafted from the toughest, most wear-resistant alloy steel. This unique combination of toughness and wear resistance ensures that the product is both highly wear-resistant and crack-free—a perfect fusion of steel and iron—endowing it with outstanding comprehensive performance, including superior wear resistance, impact resistance, and overall safety and reliability.High-chromium alloy hammer headMade from a high-chromium composite material, these hammer heads exhibit high hardness and excellent wear resistance compared to conventional high-manganese steel hammer heads. The high-hardness martensitic matrix in the sand-making machine hammer heads provides strong support for the carbide particles, preventing them from shedding from the worn surface during operation and ensuring the material’s superior wear resistance.Carbide-tipped hammer headAlso known as the "Da Jin Ya wear-resistant hammer head, " these tungsten-titanium alloy crusher hammers are manufactured using a special process that involves casting hard alloy rods and alloy blocks onto the working surface of the hammer head. This unique manufacturing approach not only delivers exceptional wear resistance but also ensures reliable safety performance. It effectively resolves the inherent conflict between hardness and toughness, enabling these hammers to perform reliably under a wide range of complex and harsh operating conditions.Coal crusher ring hammerThe ring-hammer coal crusher is a series of coal-crushing machinery specifically designed for coal-handling systems in thermal power plants. The ring hammers used in these crushers include tooth-shaped hammers and annular hammers. Through optimizing material composition, designing a rational casting process, and incorporating advanced heat treatment techniques, Jiangxi Duma has developed a new type of modified high-manganese steel ring hammer that exhibits excellent wear resistance and superior overall mechanical performance.Jiangxi Duma Machinery Manufacturing Co., Ltd. primarily manufactures accessories for jaw crushers (including tooth plates, guard plates, and pressure plates), accessories for cone crushers (such as mantle liners, crushing walls, distribution discs, and pressure sleeves), accessories for ball mills (such as lining plates and steel balls), accessories for impact crushers (such as hammer plates and lining plates), hammer heads for hammer crushers, and various wear-resistant alloy components.The company adheres to a market-oriented approach and upholds the business philosophy of "quality first, customer paramount." It has established a comprehensive quality management system in accordance with the ISO9001 quality standards, and has cultivated a highly qualified team of technical developers and production managers. Its advanced management concepts and rigorous management practices ensure both product quality and price competitiveness.We warmly welcome domestic and international business partners to visit, call, or write us for business discussions. We will provide you with high-quality service!
