Impact crusher--Almighty little assistant for mining stone crushing

Since impact crusher can crush material coarsely, medium and finely, it has been widely used in stone crushing production. Impact crusher can process material whose granularity is not over 500mm and compressive strength isn’t higher than 320Mpa, such as granite, limestone, concrete and so on. And impact crusher together with jaw crusher, hammer crusher and cone crusher supported half of the mining industry.

Working principle of impact crusher

The impact crusher gets material crushed through high-speed rotating rotors with strong impact energy impacting the fed-in hard and medium materials in the crushing cavity.

When the impact crusher is connected to the power and starts to work, the rotor in the crusher is driven by the motor to start high-speed rotation. The ore is thrown from the high-speed into the cavity of the counterattack crusher, forming a violent collision with the rotating rotor. Then, ore returns to the space range of the bouncer rotating from the counterattack board receives the second impact, and then it is thrown to the second counterattack board. After repeated impact and rebound of the rotor and the impact plate, the material will crack along its joints. The internal tissue will be impacted to loosen and shatter. The material particles that meet the crushing specifications will be pre-rolled between the rotor and the impact plate. The remaining gap is discharged out of the machine and becomes a crushed product. It is worth mentioning that the reserved clearance between the rotor and the impact plate can be appropriately adjusted according to the crushing requirements, that is why we will see that the same impact crusher can be crushed into sand and stones of different sizes.

Working advantages of impact crusher

1. It can be used to crush materials with large water content without clogging The impact crusher can be equipped with a heater for the feed chute and the impact plate device to prevent the material with a large water content from sticking when it is crushed into the machine cavity. Therefore it can effectively prevent the occurrence of material blocking.

2. There are many materials that can be broken by impact crusher, so it has wide application. The impact crusher is not only suitable for the crushing of soft materials, but also for materials with very high hardness. The scope of application covers almost the entire material processing in the mining and sand industry.

3. Impact crusher is easy to replace and has low loss Because of its special working principle, the faster wear is the hammer on the rotor, which is inevitable because of continuous impact with the material. The hammer plate on the rotor can use special tools Installation and removal, short replacement time. While the hammer damage is more serious, other locations and parts are lightly damaged, and the overall equipment is less damaged.

Among the many mining machinery and equipment, the impact crusher is a special crushing equipment that runs through the whole process of coarse crushing, medium crushing and fine crushing. It has a wide range of applications, strong crushing capacity, and good quality of finished products. Friends who want to develop their careers, start by owning an impact crusher!
