Crusher is a kind of mechanical equipment commonly used in mining, building materials, metallurgy, chemical industry, highway, railway and other industries. It is mainly used to crush large pieces of materials into smaller particles. According to the working principle, scope of application and crushing effect, crushers can be divided into many types. The following are common crusher classifications:
1. Classification by working principle
Jaw Crusher: Use the relative movement of two jaw plates to compress and crush materials, suitable for coarse and medium crushing.
Impact Crusher: Use the high-speed rotating rotor to impact and crush the material, suitable for medium and fine crushing.
Cone Crusher: Use the space between the eccentrically rotating cone and the fixed cone for crushing, suitable for medium and fine crushing, mainly for materials with higher hardness.
Hammer Crusher: Use the high-speed rotating hammer head to impact and crush the material, suitable for coarse and medium crushing of soft materials.
Vertical Shaft Impact Crusher (VSI): The material is crushed by the high-speed rotating impeller colliding with the material, and is mainly used for fine crushing in sand and gravel production.
Double Tooth Roller Crusher: It uses a toothed roller to squeeze and shear the material, and is suitable for crushing medium-hard materials.
2. Classification by crushing method
Compression crusher: Crushes the material through the compression between the materials. Typical examples include jaw crushers and cone crushers.
Impact crusher: Crushes the material through high-speed impact force, such as impact crushers and vertical shaft impact crushers.
Shearing crusher: Crushes the material through the shear force between the materials, such as double tooth roller crushers.
Grinding crusher: Crushes the material through the friction between the materials, commonly used in fine crushing equipment, such as ball mills.
3. Classification by application field
Ore crusher: mainly used in the mining industry to crush large pieces of ore into small pieces for subsequent ore dressing and processing.
Construction waste crusher: used to crush construction waste, such as waste concrete, bricks and stones, etc.
Coal crusher: used in the coal mining industry to crush large pieces of coal into smaller particles.
Cement production crusher: used to crush raw materials in cement production, such as limestone, clay, etc.
Sand and gravel production crusher: used to produce sand and gravel materials for construction, usually requiring better particle shape, suitable for impact crusher or vertical shaft impact crusher.
4. Classification by crushing particle size
Coarse crusher: used to crush large pieces of material into medium-sized particles, typical equipment such as jaw crusher.
Medium crusher: used to crush medium-sized materials into smaller particles, common equipment such as cone crusher.
Fine crusher: used to crush small particles into smaller particles, usually impact crusher or vertical shaft impact crusher.
5. Classification by structural form
Single-stage crusher: It consists of a single crushing component and is suitable for crushing harder materials.
Dual-stage crusher: It has two crushing parts and is usually used to process larger and harder materials.
Multi-stage crusher: It has multiple crushing stages and is suitable for applications with finer material particle size requirements.
6. Classification by the hardness of the crushed material
Soft material crusher: It is suitable for crushing soft materials (such as coal, gypsum, limestone, etc.).
Medium-hard material crusher: It is suitable for medium-hard materials (such as sandstone, iron ore, etc.).
Hard material crusher: It is suitable for materials with greater hardness (such as granite, basalt, etc.).
7. Classification by feeding method
Single-channel crusher: It has only one material feed port.
Dual-channel crusher: It has two feed ports and is suitable for feeding large pieces of material.
Different types of crushers have different characteristics. Choosing a suitable crusher can effectively improve production efficiency and reduce energy consumption. In practical applications, it is often necessary to comprehensively consider the selection of crusher based on factors such as material hardness, particle size requirements, and output.
