Condition: new, power: 44 kW (59.82 HP), Year of construction: 2025, A double rotor hammer crusher is a type of crusher in which two rotors are mounted on a single shaft, combined to form a spinning rotor. The double rotor arrangement enhances the crushing capabilities and provides a more efficient and reliable crusher design compared to single rotor crushers. Here are some key features and aspects of a double rotor hammer crusher: 1. Two Rotors: As the name suggests, the crusher has two rotors that rotate in opposite directions on a common shaft. This dual rotor configuration allows for increased impact and crushing power. 2. High Capacity: The dual rotor design enables the crusher to handle larger feed sizes and higher capacity compared to single rotor crushers. It is suitable for crushing materials with high hardness and large sizes. 3. Versatility: Double rotor hammer crushers are versatile and can be used in various applications, including the reduction of limestone, gypsum, coal, and other similar materials in the mining, cement, and building materials industries. 4. Impact Crushing: The primary mechanism of crushing in a double rotor hammer crusher is through the impact of the hammers against the material. The material is fed into the crusher, and the high-speed rotating hammers impact and shatter the particles. 5. Adjustable Gap Settings: These crushers often have adjustable gap settings between the rotors and the impact bars, allowing control over the final particle size. 6. Durability: The robust design of the double rotor hammer crusher makes it durable and capable of handling tough materials and continuous operation. 7. Reduced Wear: The dual rotor arrangement can help distribute wear more evenly across the hammers and other wear parts, potentially extending the overall lifespan of the crusher. Hfodsq Nf Enepfx Afisn 8. Ease of Maintenance: Some double rotor hammer crushers are designed with features that make maintenance and replacement of wear parts more accessible, reducing downtime. It's important to note that specific features and design aspects may vary among different models and manufacturers of double rotor hammer crushers. If you are considering using or purchasing one, it's recommended to consult the manufacturer's specifications and guidelines for proper operation and maintenance.
