Types of Crusher Series
The crusher series produced by our company mainly include the following types:
Broken Shaft Group for Coal Mining
The crusher shaft assembly integrates high strength, ultra-wear resistance, high efficiency, easy maintenance, and wide adaptability. The shaft body is made of high-strength alloy steel, integrally forged and precisely heat-treated, with excellent bending and torsional resistance, ensuring long-term stable operation under heavy load conditions; the wear parts use multi-alloy wear-resistant materials and surface hardening technology, improving wear resistance by more than 50%, significantly extending service life and reducing consumable costs.
Hammerheads Of Coal Mine Crushers
The hammerheads of coal mine crushers are made of high-manganese steel, ultra-high-chromium composite materials, and other high-quality wear-resistant materials, manufactured through precision casting or forging and heat treatment processes, resulting in extremely high hardness and toughness. Their structural design balances impact force and wear resistance, enabling powerful crushing of coal and rock at high speeds while resisting severe abrasive wear. Specifically designed for various hammer and impact crushers, they are key wear-resistant components that ensure crushing efficiency and reduce downtime for replacement.
Benefits of Crusher Series
Broken Shaft Group for Coal Mining
Broken shaft group for coal mining have many advantages, including:
High Reliability and Impact Resistance
Constructed from high-strength alloy steel, and treated with special heat treatment and surface hardening processes (such as welding a wear-resistant layer), it possesses extremely high fatigue strength and wear resistance, capable of withstanding the continuous high-intensity impact and wear from gangue and hard rock during underground coal mining.
Optimized Crushing Efficiency
The cutter tooth structure, layout, and shaft rotation speed are designed based on rock mechanics and crushing mechanisms. The optimized tooth shape and arrangement achieve efficient shearing and crushing of large coal and rock pieces, ensuring uniform output particle size and effectively preventing material blockage, thus guaranteeing the stable operation of the continuous transport system.
Intrinsically Safe Design
Strictly adhering to coal mine explosion-proof standards, key rotating parts employ multiple sealing and protection structures to prevent dust ingress into bearings and eliminate frictional sparks. The overall design emphasizes rigid connection and dynamic balance with the mining machinery, ensuring smooth operation and high safety redundancy.
Hammerheads Of Coal Mine Crushers
Hammerheads of coal mine crushers have many advantages, including:
Extreme Wear Resistance, Doubled Lifespan
Utilizing an optimized formula of high-chromium composite alloy or special high-manganese steel, scientifically heat-treated to form a strong and tough matrix and high-hardness carbides, it exhibits superior resistance to abrasive wear. When crushing high-gangue coal and rock, its lifespan is significantly extended compared to ordinary materials, greatly reducing replacement frequency and spare parts costs.
Balancing Rigidity and Flexibility, Unrestricted Impact Resistance
The core mechanical design balances high hardness with necessary toughness, effectively resisting the instantaneous high-intensity impact from coal and rock, especially those containing hard gangue, preventing brittle fracture and premature failure, and ensuring the continuity and stability of crushing operations.
Scientific Design, High-Efficiency Crushing
The hammer profile is optimized through dynamic simulation to maximize energy transfer during high-speed impacts, improving the primary crushing ratio and coal throughput efficiency. A rational layout helps form an ideal material layer, reducing equipment idle time and over-crushing, achieving energy saving and consumption reduction.
