2024-03-18 11:49:09

Coal jaw crusher is a mechanical equipment specially used to crush coal. Its working principle is to use the jaw plate to crush materials, and through shearing, extrusion, splitting, and other actions, the coal is broken into products of the required particle size.

Coal jaw crushers can also process other materials, such as river pebbles, granite, basalt, iron ore, limestone, quartz stone, diabase, etc.



Coal jaw crusher has significant advantages in the field of coal crushing, which are mainly reflected in the following aspects:


● Strong crushing capacity: Coal jaw crusher has a strong crushing capacity and can effectively crush coal into products of required particle size. Its crushing cavity is deep and has no dead space, which improves the feeding capacity and output. At the same time, it has a large crushing ratio and uniform product particle size.


● Economical and practical: The equipment has a reliable structure, high production efficiency, easy adjustment, good product particle shape, uniform particle size distribution, and economical use. The spring safety system serves as an overload protection device, allowing foreign iron objects to pass through the crushing chamber without harming the crusher, further reducing operating costs.


● Wear-resistant and durable: The crushing cavity of the coal jaw crusher is specially designed to make the utilization rate of jaw plate material higher. The jaw plates can be interchanged and used multiple times to achieve even wear on the crushing surface of the jaw plates, thereby improving material utilization and extending service life. In addition, its structure is simple, wear is less, and transmission parts such as eccentric shafts are less stressed, which enhances the durability of the overall equipment.


● Environmental protection and energy saving: Through the effective crushing of coal jaw crusher, harmful substances in coal can be removed and the pollution to the atmosphere during combustion can be reduced. At the same time, the equipment also has significant performance in energy saving. A single machine saves 15% to 30% of energy, and the system saves more than twice the energy, which helps reduce energy consumption in the coal processing process.


● Wide scope of application: Coal jaw crusher can be used not only for crushing coal but also for crushing other materials, such as gangue, shale, slag, etc. Its wide range of applications allows this device to play an important role in many fields.

Common coal crushing equipment mainly includes the following types:


● Coal jaw crusher: This is a fixed extrusion crusher with the characteristics of simple structure, large crushing ratio, uniform particle size, reliable operation, stable performance, easy maintenance, and low operating cost. It is often used for the first crushing of cost-effective materials.


● Coal impact crusher: This crusher can handle various coarse, medium, and fine materials with a side length not exceeding 500mm and a compressive strength not exceeding 350MPa. It uses impact energy to break materials and adjusts the gap between the impact frame and the rotor frame to change the material discharge granularity and material shape.


● Hammer coal crusher: This type of crusher crushes materials through the collision of a high-speed rotating hammer body with the materials. It has the characteristics of a simple structure, a large crushing ratio, and high production efficiency. It can be used for dry and wet crushing. The compressive strength of the material does not exceed 100MPa and the moisture content is less than 15%.


● Ring hammer coal crusher: This is a specially developed equipment for crushing coal. Its production process integrates impact, crushing, and impact, and the crushing efficiency is high.


● Mobile coal crusher: This type of crusher consists of mobile crushing equipment of various crushers, which are divided into tire mobile crushers and crawler mobile crushers. It eliminates the complex on-site infrastructure installation operations of split components, improves the flexibility of on-site layout, and can be mobilized directly on the construction site to meet different material needs.


In addition, there are some other types of coal-crushing equipment on the market, such as fine coal crushers, etc. These equipments have their characteristics and scope of application. When selecting coal crushing equipment, comprehensive considerations need to be made based on specific needs and conditions.
