Types of Stone Crusher in Quarry

In a quarry setting, stone crusher machines are essential equipment to handle the large rocks and stones extracted from the ground. These powerful machines have various types and functions designed to process different types of materials efficiently. Let’s explore some common types of stone crushers found in quarries:

Types of Stone Crushers in Quarry

  1. Cone Crusher: Cone crusher is suitable for crushing various hard and mid-hard materials. It is widely used in metallurgy, construction, road construction, chemical and silicate industries. It can crush materials with Mohs scale in middle and high hardness such as ironstone, copper ore, limestone, quartz, granite, rock and so on.
  2. Jaw Crusher: Jaw crusher is mainly used for the primary crushing process. It can break various kinds of materials with compressive strength not exceeding 320 MPa, such as granite, marble, basalt, limestone, quartz stone, river pebble, iron ore, copper ore, etc. The maximum compressive strength of materials being crushed is 320MPa.
  3. Impact Crusher: Impact crusher, also known as counter-breaking, is mainly used for medium and fine crushing operations of materials with a particle size of less than 500mm and compressive strength not more than 350MPa. It has the advantages of large crushing ratio, cubic particles of crushed materials, convenient maintenance, etc.
  4. Mobile Crusher: Mobile crusher is a combination of feeding, crushing, transportation and screening equipment. It is mainly used in metallurgy, chemical industry, building materials, water and electricity as a mobile stone station business.

Choosing the Right Type

  • Primary Crushing: Jaw and gyratory crushers are typically used for primary crushing. They are designed to handle large-sized materials and reduce them to manageable sizes for further processing.
  • Secondary and Tertiary Crushing: Cone crushers and impact crushers are commonly used for secondary and tertiary crushing stages. Cone crushers are preferred for their ability to produce finely crushed materials, while impact crushers excel at producing cubical-shaped particles.

Factors Influencing Selection

  • Material Hardness: Different crushers are suitable for different materials based on their hardness. For example, impact crushers are effective for softer materials, whereas cone crushers are better suited for harder rocks.
  • Capacity Requirements: The size and capacity of the crusher should match the requirements of the quarry operation. Jaw crushers are known for their high capacity, while cone crushers excel at producing fine particles.
  • Maintenance: Consideration should be given to the ease of maintenance and availability of spare parts for the chosen type of crusher. This ensures minimal downtime and efficient operation.

The selection of the right type of crusher depends on the material’s characteristics, the desired product size, and the capacity requirements of the quarry. Each type of crusher offers unique advantages and is suitable for different stages of crushing. Proper selection and maintenance of these machines are essential for efficient quarry operations and maximizing productivity.
