The Difference Between Hammer Crusher And Impact Crusher

There are significant differences between hammer crushers and impact crushers in multiple aspects, as follows:

Structural principle:

Hammer crusher: mainly uses high-speed rotating hammer body to collide with materials to crush them. The rotor structure is a hammer head swing hammer type, and the fineness of the discharge is controlled by the castor bars at the bottom of the screen.

Impact crusher: uses 2-3 chamber impact plates to adjust the gap between the rotor plate and hammer to control the discharge fineness. It mainly relies on impact crushing, where the material repeatedly collides and breaks between the rotor and the impact plate.

Crushed materials:

Hammer crusher: generally suitable for crushing low hardness stone materials of 200 megapascals, such as limestone, coal gangue, etc. It can be used in mining, cement, coal, metallurgy, building materials, highways, combustion and other departments to finely crush medium hardness and brittle materials.

Impact crusher: can be used to crush high hardness materials with a hardness of 300 megapascals, such as granite, river pebbles, etc. It can crush materials with medium hardness, brittleness, and moisture.

Product appearance:

Hammer crusher: Due to the use of a swinging hammer and a hammer head to break, its products have more flake stones.

Counterattack crusher: Its product has a cubic particle shape, which is because it uses the principle of counterattack to repeatedly hit and eject to break.

Usage and crushing method:

Hammer crusher: It can directly feed large materials for crushing, with a relatively large crushing ratio, and can achieve a combination of coarse and fine crushing.

Counterattack crusher: It needs to be used in conjunction with head crusher, and the feed particle size should not be too large.

Energy consumption and consumption of vulnerable parts:

The impact crusher is usually more energy-efficient than the hammer crusher of the same model, and the vulnerable parts are more durable, with lower maintenance frequency.

Overall, hammer crushers and impact crushers each have their own characteristics, and the choice of equipment depends on specific crushing needs, material properties, and production requirements.
