Introduction of Hammer Crusher
Hammer crusher is a kind of mechanical equipment that uses high-speed rotating hammers to impact and crush materials. It is mainly used for medium and fine crushing of medium-hardness and brittle materials. The particle size of the material can be adjusted. It is widely used in mining, building materials, the chemical industry, metallurgy, and other industries.
Hammer crushers are mainly used for medium or fine crushing of medium hardness and brittle materials (such as limestone, coal, gypsum, shale, etc.), and can crush materials to 5-20mm or even smaller. Some models can directly crush large pieces of material to the required particle size (one-time forming) without multi-stage crushing. A single machine can achieve coarse to fine crushing, reducing production processes. Hammer crusher is an efficient crusher choice for crushing medium-soft and brittle materials due to its high crushing ratio, simple structure, and low cost. The finished products after crushing are mostly uniform cubes or regular particles, which are suitable for high-standard aggregate needs.
working principle of Hammer crusher
The motor drives the rotor to rotate at high speed in the crushing cavity. The material is fed into the machine from the upper feed port and crushed by the impact, shearing and grinding of the high-speed hammer.
In the lower part of the rotor, there is a sieve plate, the particle size of the crushed material that is smaller than the size of the sieve hole is discharged through the sieve plate, and the coarse particle size larger than the sieve hole size is retained on the sieve plate to continue to be hit and grinded by the hammer, and finally passes the sieve plate out of the machine.
Why choose JXSC hammer crusher
features & Advantages of hammer crusher
- The hammer head of JXSC hammer crusher is cast from high manganese steel, which has high density, wear resistance and impact resistance.
- The production capacity is high, and the finished products are uniform; the required discharging granularity can be adjusted according to customer requirements.
- The machine body structure is sealed, which solves the problems of dust pollution and ash leakage in the crushing workshop.
- Simple and durable structure: no complex transmission parts, easy maintenance, low failure rate.
- Strong adaptability to wet and sticky materials: the non-screen bottom design can handle materials with high moisture content (such as clayey coal gangue).
- Low energy consumption: compared with jaw crusher and cone crusher, the power consumption per unit output is reduced by 15%-30%.
- One-step forming: Some models can directly produce finished products of qualified particle size without the need for secondary crushing.
- We can customize fixed or mobile types and heavy-duty hammer crushers for large crushing production lines.

Structure of hammer crusher
The main working part of a hammer breaker is a rotor with a hammer (also called a hammer head). The rotor is composed of a main shaft, a disc, a pin and a hammer. The motor drives the rotor to rotate at high speed in the crushing cavity. The material is fed into the machine from the upper feed port and crushed by the impact, impact, shearing and grinding of the high-speed hammer. There is a sieve plate at the lower part of the rotor. During crushing, the particle size smaller than the sieve hole size is discharged through the sieve plate. The coarse particle size larger than the sieve hole size is retained on the sieve plate to continue to be hit and ground by the hammer, and finally passes through the sieve plate Out of the machine.
