Hammer crusher

Hammer crusher is a device that uses a high-speed rotating hammer head to exert strong impact on materials and achieve crushing. It has a simple structure and easy maintenance, and is widely used in various industries.

Working principle

The working principle of a hammer crusher is mainly to use a high-speed rotating rotor to drive the hammer head to impact and crush the material, crush the material through the impact force, and then separate materials of different particle sizes through a sieve plate.

The working process of a hammer crusher can be divided into several key steps. When the material enters the crushing chamber through the feeding port, the motor drives the rotor to rotate at high speed, and the hammer on the rotor collides with the material at high speed. This impact generates significant impact energy, causing the material to be instantly shattered. At the same time, the material is also subjected to shear and friction during the impact process, accelerating its crushing process.

After multiple impacts, the particle size of the material gradually decreased. At this moment, the gravity of the material itself causes it to rush from the high-speed rotating hammer head towards the baffle and sieve inside the machine body. Materials larger than the sieve size are retained on the sieve plate and continue to be hit and ground by the hammer until they are crushed to the desired discharge particle size, and finally discharged outside the machine through the sieve plate.

Overall, hammer crushers can quickly crush materials into the desired particle size range through their efficient impact crushing mechanism. Its working principle not only relies on the high-speed impact of the hammer head, but also involves the collision between the material and the counterattack plate, as well as multiple crushing processes, ensuring the fine crushing effect of the final product.

Highlight The Advantages

  • Simple structure

    The design of a hammer crusher is relatively simple, mainly composed of components such as a box, rotor, and hammer head. This structure simplifies the manufacturing and maintenance process of the equipment, enabling the hammer crusher to be quickly put into use in various industrial applications.

    Due to its simple structure, the hammer crusher has a lower failure rate and is easier to maintain. When it is necessary to replace vulnerable parts such as hammers, a simple structural design also enables maintenance personnel to quickly carry out replacement operations.

  • Easy maintenance

    The main working components of the hammer crusher, such as the hammer head and lining plate, can be easily replaced without the need for cumbersome steps and professional tools. For example, the hammer head is connected to the rotor through a pin shaft, allowing for quick disassembly and installation.

    The equipment is designed with a centralized lubrication system that can lubricate each bearing while the machine is running, reducing production delays caused by downtime maintenance.

  • Efficient crushing capability

    The hammer crusher uses a high-speed rotating hammer head to impact and crush materials, with high crushing efficiency and the ability to handle large amounts of material input. For example, a large single-stage hammer crusher can directly crush limestone with a diameter of 1 meter to about 20mm.

    This device is not only suitable for crushing materials with medium hardness, but also for processing materials with high humidity. It has a wide range of applications and can easily handle materials from limestone to coal.
