A stone crusher is a mechanical device used to break large pieces of stone into smaller particles. It is widely used in mining, construction, roads, railways and other industries. There are many types of stone crushers. The following are several main types that are introduced in detail according to different classification methods:
Classification by working principle:
• Suitable for crushing medium-hard materials, with two types of coarse crushing and fine crushing.
• With a large crushing ratio and high output, it is the preferred equipment for primary crushing.
• Uses impact energy to crush materials. It is suitable for processing various coarse, medium and fine materials with a side length of no more than 500mm and a compressive strength of no more than 350MPa.
• With a unique structure and high crushing efficiency, it is widely used in highway construction, water conservancy projects and other fields.
• Suitable for crushing medium-hardness or high-hardness materials, such as river pebbles, granite, etc.
• There is a group of annular crushers in the crushing chamber, which can continuously compress the material until it is broken.
• Mainly suitable for crushing medium-hard materials with a hardness not exceeding 150MPa, such as limestone, gypsum, etc.
• The material is hit and crushed by multiple high-speed rotating hammers to achieve the purpose of crushing.
Classification by mobility:
Fixed stone crusher:
• Installed in a fixed position, suitable for large-scale, long-term crushing operations.
• High mobility, can be moved according to processing requirements, suitable for mobile crushing operations in various complex working conditions.
Classification by crushing particle size:
Coarse crusher:
• Mainly used for the initial crushing of large stones, such as jaw crusher.
Medium crusher:
• Used to further crush the coarsely crushed stones to medium particle size, such as cone crusher.
Fine crusher:
• Used to crush the medium-crushed stones to smaller particle size, such as impact crusher and impact crusher.
Other types:
Impact crusher:
• The discharge fineness is finer, generally used for level 3 and above crushing or artificial sand making, etc.
Hammer crusher:
• One-step forming equipment that can directly crush large stones into usable stones without the need for head crushing equipment.
In summary, there are various types of stone crushers. According to different classification methods such as working principle, mobility, crushing particle size, etc., they can be divided into jaw crushers, impact crushers, cone crushers, hammer crushers and other types. These equipments have their own characteristics and are suitable for different crushing needs and industry fields.
