Reversible Hammer Crusher
The reversible hammer mill crusher is specifically designed for the fine crushing of medium-hardness materials such as coal, coke, and slag. It is widely used in material pre-processing stages across industries, including thermal power generation, coking, and steel manufacturing. It is particularly well-suited for crushing sticky or damp materials with high moisture content and is capable of achieving a fine output product with a particle size of ≤3 mm.
- Capacity: 83-360 t/h
- Feed Size: ≤80 mm
- Output Size: ≤3 mm
The reversible hammer crusher is an industrial stone crushing machine designed for the fine crushing of brittle materials with low-to-medium hardness (such as limestone or coal) across sectors including metallurgy, construction materials, chemicals, and power generation. Combining the features of both hammer crushers and impact crushers, it offers a high crushing ratio (up to 20:1), low energy consumption, and consistent product particle size.
The core components of the reversible hammer mill crusher include the frame, rotor, hammer heads, screen bars, and a hydraulic system for opening the housing from either side to facilitate maintenance. It is suitable for crushing materials with a compressive strength of up to 150 MPa. The machine features a reversible rotor design. By rotating in both directions, it extends the service life of the hammer heads. Material is crushed through high-speed impacts against baffle plates and screen bars. An integrated heating system for the impact plates allows for the processing of materials with high moisture content or sticky properties. Furthermore, the hammer heads are attached via flexible connections, allowing them to retract upon encountering foreign objects to prevent clogging.
The equipment is also equipped with an advanced hydraulic opening system, which enables rapid opening and closing of the maintenance access doors, significantly reducing downtime for servicing.
Reversible Hammer Crusher Working Principle
After entering the reversible hammer crusher via the feed hopper, the material encounters high-speed rotating hammers, which propel it against the adjustable, wear-resistant toothed plates located at the crusher inlet, resulting in an initial round of crushing. The material then enters the main crushing chamber, where it undergoes a secondary, primary crushing process.
Within the main crushing chamber, the material particles—already homogenized—gain further kinetic energy from the hammers and are propelled at high speed toward the toothed lining plates within the impact chamber. Upon rebounding from these toothed liners, the particles are struck by the hammers once again. Simultaneously, the material is further broken down through collisions between the particles themselves.
Through this repetitive cycle, the material is crushed multiple times within the impact chamber before finally being discharged through the outlet. The resulting finely crushed material constitutes the finished product. The particle size of the final product is controlled by adjusting the gap between the rotor and the impact plates.
Advantages of Reversible Hammer Mill Crusher
1) Reversible Bidirectional Crushing Structure
The rotor can rotate in both forward and reverse directions, allowing both sides of the hammer heads to be used for crushing. This ensures even wear, significantly reducing the frequency of replacing wear parts and lowering maintenance costs.
2) Suitable for Wet Materials
Featuring a specialized anti-clogging grate design and an enlarged crushing chamber, the equipment can process sticky or wet materials with a moisture content of up to 15%. This effectively prevents clogging and ensures continuous production.
3) Adjustable Gap
Mechanical gap adjustment allows for precise control over the output particle size.
4) Easy Maintenance
The reversible hammer crusher is equipped with an advanced hydraulic opening system, enabling rapid opening and closing of the access doors, which greatly reduces maintenance downtime.
5) Efficient and Convenient
With its compact design and small footprint, the reversible hammer mill crusher offers flexible and convenient installation. It is particularly well-suited for upgrading existing production lines or for use in space-constrained operating environments, providing users with a stable and highly efficient crushing solution.
