A crusher is a common type of ore processing equipment. It can crush large pieces of ore or stone into smaller particles for subsequent processing and utilization. So, how does a crusher work? Let’s take a look at them one by one.
How Does the Crusher Work
The working principle of the crusher is to use a high-speed rotating hammer or blade to apply pressure and impact on the ore or stone. As a result, the material is broken up to form smaller particles. The crusher is usually composed of inlet, outlet, rotor, screen and other components.
The Types of Crusher
According to different crushing principles and structural forms, crushers can be divided into many types. For example, there are mainly impact crushers, cone crushers, jaw crushers, etc. Different types of crushers are suitable for different materials and processing requirements.
The Working Process of the Crusher
When the raw material is fed into the feed port of the crusher, they are subjected to a rotating rotor or a vibrating hammer. These rotors or hammers rotate or vibrate at high speeds, transferring energy to the material. The material begins to crack due to strong impact and pressure.
The design and working principle of the internal structure varies depending on the type of crusher, and the following takes an impact crusher as an example:
Feeding:
The raw material enters the crusher from the feed port. The crusher is usually equipped with an adjustable feeding device to ensure that the material is evenly distributed in the crushing chamber.
Fragmentation:
The rotor rotates or vibrates at high speed to hit the material onto the screen. Larger materials are impacted and squeezed, resulting in smaller materials.
Discharging:
The crushed particles are discharged through the gap of the screen to reach the required size. Depending on the need, the pore size of the screen can be adjusted to control the particle size of the output.

Crusher Selection and Maintenance
When choosing a crusher, it is necessary to consider the hardness, size, output and other factors of ore or stone to select the appropriate crusher model and specification. At the same time, regular maintenance and maintenance of the crusher can extend its service life and improve production efficiency.
To sum up, the crusher breaks down large pieces of material into small particles by applying pressure and impact. Its working principle consists of three key steps: feeding, fragmentation and discharge.
