Introduction of impact crusher
Impact crushers are widely used in mineral, rock, stone, and aggregate processing plants, with high production efficiency and good safety performance. It’s mainly used for medium or fine crushing of materials with medium hardness or below (such as limestone, coal gangue, shale), and produce uniform finished product particle size (generally 0-50mm). With high-speed rotating rotor + plate hammer impacting materials, the crushing ratio is large (up to 50:1), and the finished product particle shape is excellent. According to the arrangement type of impact rotor and shaft, impact crushers can be divided into horizontal shaft impact crushers (HSI) and vertical shaft impact crushers (VSI). The core feature of the impact crusher is its flexible adjustment function, which can adjust the discharge port at any time according to the needs to achieve different finished product requirements.
It is suitable for coarse crushing (primary crushing), medium and fine crushing (secondary crushing) and shaping operations. The materials crushed by impact crusher are mostly in cube shape, which is suitable for the production of high-quality sand and gravel aggregates and building materials. It can also be designed as mobile impact crusher plants. With the characteristics of high crushing ratio, good particle shape and flexible control, it has become the core crushing equipment for medium and soft materials.
JXSC can also be configured with a vibrating screen and feeder to form a mobile impact crusher, providing high-quality cubic finished materials for the production line.
working principle & structure of Impact Crusher
Working principle
The V-belt connected with the motor drives the impact crusher to rotate in a fixed direction. There are multiple sets of suspension impact plates above the rotor. The material enters the crushing cavity through the feeding hole and guide rail. The blower rod fixed on the rotor impacts the material onto the counter-attack plate and then falls from the counter-attack plate onto the colliding material blocks.
Therefore, the materials move repeatedly in the crushing cavity composed of the rotor, the impact plate, the hammer and the striking rod. By adjusting the angle and distance of the impact anvil, the gap between the impact plate and the hammer can be adjusted according to actual needs. You can control product throughput by varying rotor speed, input feed, and grind screen configuration.
Structural features
- Impact plate design: The adjustable design allows for quick adjustment according to the material characteristics.
- High-efficiency rotor: The high-speed rotating rotor is combined with a heavy hammer to maintain high impact force.
- Large feed opening: It is convenient for large pieces of material to enter and increase the feed speed.
- Wear-resistant material: The key components are made of highly wear-resistant alloy materials to extend the service life.
- Multiple safety devices: Equipped with safety devices such as overload protection and emergency shutdown.
Why choose JXSC impact crusher
features & Advantages
1. The crushing cavity is large and the feed particle size range is wide; the crushed finished particles are cubic and have good particle shape.
2. The impact crusher is more effective in processing materials with large amounts of moisture and effectively prevents material clogging.
3. Its rotor is powerful and crushes harder materials with minimal energy consumption.
4. JXSC impact crusher can adjust the discharge particle size in various ways, such as adjusting the rotor speed, the gap between the impact plate and the grinding chamber, etc.
5. This impact crusher adopts high-chromium blow hammer and unique impact liner, which are wear-resistant and have high utilization rate.
6. High efficiency and energy saving: a single machine can complete multiple stages of crushing, simplify the process, and consume less energy than the traditional jaw crusher + cone crusher combination.
7. Adapt to wet and sticky materials: the model without grate design can reduce blockage, which is better than the hammer crusher.
