Impact Crusher Working Principle

PUDONG, China - Nov. 25, 2020 - PRLog -- The impact crusher is a new type of crushing equipment with high efficiency. It is characterized by small volume, simple structure, large crushing ratio, low energy consumption, large production capacity, uniform product size and selective crushing effect. Impact crusher  is widely used in mining, metallurgy, chemical industry, construction, highway, railway and other engineering construction fields.

1、 Working principle of impact crusher

As the name suggests, the impact crusher uses the impact force to achieve the crushing effect. After the large pieces of material enter the crushing cavity between the impact plate and the rotor, the kinetic energy is obtained by the rotation of the rotor part. The impact is repeated between the impact plate and the rotor, and is broken step by step through the first stage impact chamber, the second stage impact chamber and the bottom grinding chamber, so as to achieve the required discharge particle size.

2、 Technical advantages of impact crusher

The crushing machine can effectively prevent the blocking of materials

When the moisture content of the material is too high, the feeding chute and impact plate of the impact crusher can be equipped with heating device to prevent the material from sticking. The impact crusher does not need to be equipped with bottom sieve plate, which can effectively prevent blockage. The hammer crusher can not use heating to prevent the material from sticking, and must be equipped with bottom sieve plate, which increases the possibility of blockage.

2. The impact crusher is suitable for both soft and very hard materials

The plate hammer of impact crusher (https://m.sbmchina.com/products/pf.html) is fixed on the rotor by mechanical clamping structure, and has a large moment of inertia when it rotates with the rotor. Compared with the hammer crusher (the hammer head is suspended), the rotor of the impact crusher has greater momentum, which is suitable for crushing harder materials, and has lower energy consumption.

3. It is convenient and flexible to adjust the discharge particle size with wide adjustment range

The discharge particle size of impact crusher can be adjusted in many ways, such as adjusting the rotor speed, adjusting the gap between impact plate and grinding chamber, etc. The gap adjustment can be done by mechanical or hydraulic adjustment, and the clearance can be adjusted easily by local operation button or transportation control system by using hydraulic adjustment system. However, the adjustment of discharge particle size of hammer crusher can only be realized by changing the bottom sieve plate.
