Although impact crushers and hammer crushers are somewhat similar in terms of crushing principles, there are still certain differences in specific technical structures and working principles.
1. The difference in technical structure First of all, the impact crusher has a large crusher cavity and a large feeding port. The material is not only impacted by the hammer, but also repeatedly impacted by the material in the impact crusher chamber, the impact plate, and the material, which has a better crushing effect. The crusher cavity of the hammer crusher is relatively small and relatively sealed.
2. Impact crusher with different working principles is a crusher machine that uses impact energy to crush materials. When the machine is working, driven by the motor, the rotor rotates at a high speed. When the material enters the blow bar area, it collides with the blow bar on the rotor and breaks, and then is thrown to the impact device to be crushed again, and then bounces off the impact liner. Go back to the action area of the blow bar for re-crushing. This process is repeated. The material enters the first, second and third impact chambers from large to small for repeated crusher until the material is crushed to the required particle size and discharged from the discharge port. The hammer crusher mainly relies on impact energy to complete the crusher operation of materials. When the hammer crusher is working, the motor drives the rotor to work, and the material enters the crusher cavity evenly, and the high-speed rotating hammer impacts and cuts the torn material.
3. The method of adjusting the output granularity is different. Impact crusher is mainly controlled by adjusting the rotor speed and rotor diameter, adjusting the opening size of the distributor and the gap between the grinding chambers. The hammer crusher can control the particle size of the finished product by adjusting the gap size of the sieve plate.
4. Due to the characteristics of its technical structure and working principle, different impact crusher of processed materials can not only process soft materials, but also process medium and hard materials. Hammer crushers are only suitable for processing materials with low hardness. In addition, the impact crusher does not have grates, so it can avoid clogging when processing materials with high water content.
5. The price of impact crushers with different production costs is higher than that of hammer crushers. But the cost of post-maintenance is higher than that of hammer crusher. This is closely related to their accessories materials. The wear of the impact breaker is generally on the side facing the material, while the hammer breaker has a larger contact surface and wears faster. On the other hand, when replacing parts in impact crushing, you only need to open the rear shell of the crusher to replace them, and the time and labor costs are relatively low. Hammer Break has many hammers. It takes a lot of time and manpower to replace a set of hammers, and the relative cost is higher. Generally speaking, the maintenance cost of hammer crushing is much higher than that of impact crusher.
