Jaw crusher and impact crusher are both important equipment in crushing machinery, but they have significant differences in structure, working principle, application field, and performance characteristics; these differences have their own advantages, and users can choose the appropriate crushing equipment according to their needs and crushed materials.
Let's take you to understand the differences between a jaw crusher and an impact crusher!
1. Different structures and working principles
The jaw crusher consists of two jaw plates, the movable jaw, and the static jaw, to form a crushing chamber, simulating the movement of the two jaws of an animal to complete the material crushing operation; the movable jaw plate makes a periodic reciprocating motion on the fixed jaw plate, sometimes approaching and sometimes leaving. When approaching, the material is squeezed, split, and impacted between the two jaw plates and crushed; when leaving, the crushed material is discharged from the discharge port by gravity.
The impact crusher is mainly composed of a rotor (plate hammer), an impact plate, a frame, and other parts; the impact energy is used to crush the material, and the material is repeatedly impacted and crushed between the rotor (plate hammer) and the impact plate.
2. Different application fields
Jaw crusher: widely used in the crushing of various ores and bulk materials in industries such as mining and smelting, building materials, roads, railways, water conservancy, and chemical industry. The maximum compressive strength of the crushed material is 320Mpa, and it is often used as a coarse crusher and a medium crusher.
Impact crusher: mainly used for the processing of materials that often need to be relocated in metallurgy, chemical industry, building materials, hydropower, etc., especially for the operation of mobile stones such as highways, railways, and hydropower projects. It can handle materials with a side length of less than 100-500 mm, and the maximum compressive strength can reach 350 MPa.
3. Different performance characteristics
Jaw crusher
1. Low noise, less dust: conducive to environmental protection and improvement of the working environment.
2. Large crushing ratio, uniform product particle size: suitable for a variety of crushing needs.
3. Simple structure, reliable operation: low operating costs, simple maintenance.
4. Deep crushing chamber and no dead zone: improved feeding capacity and output.
5. Equipment energy saving: single machine energy saving 15% to 30%, system energy saving more than doubled.
6. The adjustment range of the discharge port is large: it can meet the requirements of different users.
Impact crusher
1. The feed port is large and the crushing chamber is high: it is suitable for materials with high hardness, large crushing, and less stone powder in the product.
2. The gap between the impact plate and the hammer is easy to adjust: the discharge particle size can be effectively controlled, and the particle shape is good.
3. Compact structure, strong machine rigidity: the rotor has a large moment of inertia, and is impact-resistant and wear-resistant.
4. The finished product is a cube, without tension and cracks: the particle shape is good, and it is widely used in ore crushing, railways, highways, energy, cement, chemicals, construction, and other industries.
4. Other differences
• Material hardness adaptability: jaw crushers can crush various hard materials, while impact crushers are more suitable for limestone, lime, and other hard and below-low toughness and brittle materials.
• Feed particle size: jaw crushers are generally used to crush large materials, and the allowable feed particle size is larger; impact crushers are mainly used to process some small and medium-sized materials, and the allowable feed particle size range is narrower.
• Production capacity: Generally speaking, the production capacity of jaw crushers is greater than that of impact crushers. The specific output depends on the equipment model and manufacturer.
• Discharge fineness: The jaw crusher is coarse crushing, and the discharge fineness is large; impact crusher is used as intermediate crushing or fine crushing, and the discharge fineness is smaller.
