Jaw crusher has many advantages such as a large crushing ratio, simple structure, durability, adjustable discharge, deep crushing cavity, energy saving and environmental protection, etc. Therefore, it has been widely used in fields such as aggregate production, construction material recycling, and mining operations.
The jaw crusher is mainly used for primary crushing, and the broken stones are relatively large. Impact crushers, cone crushers, etc. are used to crush medium-sized stones and are mostly used for secondary crushing.
The jaw crusher has a high crushing ratio, which means it can effectively break large pieces of materials into smaller particle sizes. At the same time, by adjusting the parameters of the equipment, uniform product particle size can be obtained to meet different production needs.
The structure of the jaw crusher is relatively simple, which makes it more convenient to operate and maintain. The bearings, moving cone, and other parts of the jaw crusher have been optimized and designed to withstand greater impact and wear, extending the service life of the equipment.
Jaw crushers are usually equipped with a discharge port adjustment device, which can easily adjust the discharge particle size. This enables it to adapt to materials of different specifications and hardness, improving the adaptability and flexibility of the equipment.
The crushing cavity of the jaw crusher is designed to be deep and there is no dead space, which helps to increase the feeding capacity and output. At the same time, the crushing efficiency of the equipment has also been improved, saving energy consumption and production costs.
Jaw crusher plays a vital role in the Aggregate Crushing Plant. It is the main crushing equipment in the stone production line, responsible for the preliminary crushing of large materials and laying the foundation for subsequent crushing and processing processes.
The jaw crusher plays a key role in the stone production line. Its powerful crushing capacity, uniform crushing effect, flexible discharge particle size adjustment, high efficiency, and low energy consumption make it an ideal choice for the stone production line.
The working principle of jaw crusher
Although the jaw crusher has various structural types, its working principle is the same, that is, the material is crushed by the periodic motion of the movable jaw. In the process of swinging the movable jaw to the fixed jaw around the suspension mandrel, the material between the two jaw plates is subjected to the combined action of crushing, splitting and bending. At the beginning, the pressure is small, so that the volume of the material is reduced, and the materials are close to each other and squeezed tightly; when the pressure rises beyond the strength that the material can bear, it will break. On the contrary, when the movable jaw leaves the fixed jaw and swings in the opposite direction of the car, the material moves downward by its own weight. Each periodic movement of the movable jaw causes the material to be crushed once and sent down a certain distance. After several cycles, the crushed materials are discharged from the discharge port.
