In a quarry, a secondary crusher usually refers to a device that further crushes the material after the primary crushing (primary crushing). The primary crushing usually uses equipment such as a jaw crusher or a gyratory crusher to crush large pieces of raw stone into smaller particles for subsequent crushing and processing.
The secondary crusher is mainly responsible for further refining the material after the primary crushing to the required particle size. Common types of secondary crushers include:
Cone crusher: Cone crusher is widely used due to its efficient crushing capacity and precise particle size control. It uses a rotating cone to compress and crush the material, and is suitable for processing medium hardness and hardness materials. Cone crushers usually have a variety of chamber types to choose from to meet different crushing needs.
Impact crusher: The
impact crusher uses the plate hammer or hammer head on the high-speed rotating rotor to impact the material, so that the material is impacted, crushed and shaped multiple times in the crushing chamber. It is suitable for processing medium hardness and soft materials, and can produce better particle shape. The impact crusher has the advantages of high crushing efficiency and flexible particle size control.
The selection of secondary crusher should be based on the nature of the material, the required particle size, production capacity and investment cost. At the same time, the stability, reliability and environmental performance of the equipment are also important factors to pay attention to during the selection process.
In the quarry, the secondary crusher is usually used in conjunction with the screening equipment to form a complete crushing and screening system. After the secondary crushing, the material is sorted by the screening equipment to obtain the finished material that meets the requirements. Such a system can ensure that the quarry can efficiently and stably produce stone products that meet the requirements.
