Overview of Different Types of Stone Crushers and Their Working Principles

The role of the stone crusher is to crush large stones into different sizes of small gravel to meet project requirements, especially for highways with stringent quality requirements.

The jaw crusher mainly consists of a fixed jaw plate and movable jaw plates. Its working principle involves periodic reciprocating motion of the movable jaw plate on the fixed jaw plate, crushing stones between the two jaws. It can crush stones with great hardness and large size, but the resulting material size is also large. It is generally used for coarse crushing.

The hammer crusher mainly consists of hanging hammers and a rotary table. Its working principle involves the free-hanging hammers on a turntable that is rapidly rotating, crushing stones with the hammer’s rotation. It is suitable for crushing hard stones and characterized by low machinery cost and high production efficiency. However, the resulting high content of gravel pin sheet is not suitable for highway projects.

The impact crusher mainly consists of a rotor, hammer, and counterattack plate. Its working principle involves smashing stones with high-speed rotating flat hammers, with the stones flying out and hitting the counterattack plate for further crushing. It is suitable for crushing hard stones and produces uniform aggregate particle sizes that are close to a cube, with less content of gravel pin sheet.

Therefore, the impact crusher is the ideal processing equipment for high-level road construction, especially suitable for crushing hard rocks, with high efficiency and energy-saving features, cubic product shape, adjustable discharging particle size, and simplifying the crushing process. Because of its excellent performance, it is widely used in highway construction, hydraulic engineering, gravel processing construction, and other fields.
