The Principle and Simple Introduction of Rotary Crushers
2019-08-28
Circular Crusher It is a type of equipment where the crushing cone inside the crushing chamber performs a gyratory oscillating motion, exerting compressive and torsional forces on the material fed into the chamber. As a result, large chunks of material are perfectly crushed into particles of specific sizes within the crushing chamber. The main shaft is mounted on a bushing positioned at the central support point inside the equipment, while its lower end fits snugly into the eccentric hole of the sleeve. When the gyratory sleeve of the crusher moves in a directional manner, the main shaft drives the crushing cone to perform a continuous rotational motion around the eccentric axis. Because this rotational movement occurs continuously and without interruption, the equipment boasts significantly higher production efficiency compared to conventional machines—naturally leading to increased output as well.
How it works
It is a large-scale crushing machine that utilizes the gyratory motion of a破碎锥 (crushing cone) within the conical cavity inside the machine shell, generating compressive, splitting, and bending forces to coarsely crush ores or rocks of varying hardness. The upper end of the main shaft, which houses the crushing cone, is supported by a bushing located in the center of the crossbeam, while its lower end fits snugly into an eccentric hole in the sleeve. As the sleeve rotates, the crushing cone performs an eccentric, gyratory motion around the machine's central axis. This continuous crushing action ensures higher efficiency compared to jaw crushers.
The principle is the same as that of a jaw crusher, but here, the crushing chamber consists of an annular space formed between a moving cone and a stationary cone. At any given moment, part of the material is being crushed, while the corresponding portion on the opposite side is simultaneously discharged downward—making this a continuous-operation system.
Performance Features
1. Compared to other crushers, this one boasts higher production efficiency due to its unique design structure, resulting in a greater equipment output.
2. This crusher equipment, through certain system optimizations, ensures high-quality production output while maintaining a relatively low power consumption, thereby helping users save on operational costs.
3. Thanks to the device's uniquely designed crushing chamber, it achieves more thorough material breakdown, resulting in a more uniform particle size that better meets consumers' stringent stone-material requirements.
4. Thanks to the special design of the feed inlet, there’s no need to equip a feeder when using the gyratory crusher, which helps consumers with less extensive production lines save on investment costs.
5. The equipment itself has a relatively simple structure, allowing users to quickly become familiar with its operating procedures. Additionally, maintenance and troubleshooting of the device are both straightforward and easy for users.
6. After optimization by our company's technical engineers, the crushing chamber has seen a significant improvement in equipment performance. The splashing of stones during material crushing is now minimized, greatly enhancing both the operational safety and the service life of the crusher.
