What is the difference between jaw crushers and hammer crushers
Both jaw crushers and hammer crushers are crushing equipment used in production lines, typically employed for primary crushing. They offer advantages such as high throughput and strong processing capacity. So, what distinguishes jaw crushers from hammer crushers?
1. Different Crushing Principles
Jaw crushers utilize jaw plate compression for crushing. This involves the crushing action achieved between the moving jaw plate and the stationary jaw plate. As the moving jaw plate continuously approaches and retreats from the stationary jaw plate, the material trapped between them undergoes compression and falls, repeating this cycle to complete the crushing process.
Hammer crushers utilize internal hammers to break materials through impact and collision forces. The hammers rotate continuously, striking and colliding with the material to achieve fragmentation.
2. Different Structural Composition
The jaw crusher consists of a moving jaw plate, stationary jaw plate, side guard plates, bearings, eccentric shaft, moving jaw rod screw, adjustment mechanism, and toggle plate. Visibly, the flywheel is prominent. This flywheel ensures smooth operation during high-speed, high-intensity running while minimizing machine vibration.
The hammer crusher primarily consists of hammers, impact plates, support rings, a central shaft, discharge port, rotor disc, screen plates, and curved liner plates. With its simple structure and strong impact capability, the hammer crusher combines the functions of jaw, impact, and hammer crushers. Consequently, it serves as an excellent alternative to jaw crushers in certain crushing applications.
3. Different Application Scopes
Regarding application scope, the jaw crusher excels as coarse crushing equipment, effortlessly processing over a hundred types of materials. It features a high crushing ratio and deep crushing chamber, where material begins breaking in the upper chamber, delivering excellent overall hourly output and processing capacity.
Although the hammer crusher combines the functions of jaw, impact, and hammer crushers, it is generally suited for processing softer materials. Its internal hammers are prone to damage when handling harder materials, making it more appropriate for crushing softer substances.
