Introduction to Jaw Crusher

Introduction to Jaw Crusher

Jaw crusher, commonly known as jaw crusher or tiger mouth, is a crushing equipment widely used in mining, smelting, building materials, highways, railways, water conservancy and chemical industries. The following is a detailed introduction to jaw crushers:
1、 Working principle
The working principle of a jaw crusher is mainly based on the relative motion of two jaw plates, one is a fixed jaw plate (fixed jaw) and the other is a movable jaw plate (moving jaw). The movable jaw plate performs periodic reciprocating motion on the fixed jaw plate, sometimes approaching and sometimes leaving. When approaching, the material is crushed by compression, splitting, and impact between the two jaw plates; When leaving, the crushed material is discharged from the discharge port by gravity.
Specifically, the motor drives the belt and pulley, and the movable jaw moves up and down through an eccentric shaft. When the movable jaw rises, the angle between the elbow plate and the movable jaw increases, thereby pushing the movable jaw plate closer to the fixed jaw plate. The material is crushed multiple times through squeezing, rubbing, and grinding between the two jaw plates; When the movable jaw descends, the angle between the elbow plate and the movable jaw decreases, and the movable jaw plate leaves the fixed jaw plate under the action of the pull rod and spring. The crushed material is freely discharged through the discharge port at the lower part of the jaw cavity under the action of gravity. With the continuous rotation of the electric motor, the moving jaw performs periodic crushing and discharging, achieving mass production.

2、 Type
According to the different swinging modes of the movable jaw plate, jaw crushers can be divided into the following three types:
Simple swing jaw crusher (simple swing jaw crusher): The moving jaw only swings in a simple circular arc. The structure of the simple swing jaw crusher is compact and simple, and the eccentric shaft and other transmission components are subjected to less force; Due to the small vertical displacement of the moving jaw, there is less excessive crushing of the material during processing, and the wear of the moving jaw plate is relatively small.
Complex swing jaw crusher (compound swing jaw crusher): The moving jaw moves up and down while swinging in a circular arc.
Integrated swing jaw crusher: combines the characteristics of simple swing and compound swing.
3、 Characteristics
Large crushing ratio: capable of crushing large materials into smaller particles, with a crushing ratio generally ranging from 3 to 6.
Uniform product particle size: The particle size distribution of the crushed material is uniform, meeting the subsequent processing requirements.
Simple structure: The device has a simple structure, easy manufacturing, and reliable operation.
Low operating costs: reliable lubrication system, easy component replacement, and simple equipment maintenance.
Low noise and less dust: With the increasing environmental requirements, jaw crushers have also made significant progress in noise control and dust suppression, reducing their impact on the environment.
Large range of discharge port adjustment: The size of the discharge port can be adjusted according to the needs of different users to meet different particle size requirements.
4、 Application Fields
Mining industry: In mining engineering, jaw crushers can crush various hard ores and rocks into particles of appropriate size, providing raw materials for subsequent beneficiation and smelting.
Construction industry: Jaw crushers can be used for the production of building materials, such as crushing limestone, granite, etc. into concrete, mortar, etc. In addition, it can also crush construction waste into recyclable materials, promoting the green development of the construction industry.
Road engineering: In highway, railway and other road engineering, jaw crushers can crush various stone materials for roadbed and pavement laying.
Chemical industry: In chemical production, jaw crushers can be used to crush raw materials such as coal, sulfur, and phosphate ore, providing stable and reliable raw material supply for chemical production.
In the field of environmental protection, jaw crushers can crush urban waste, scrap iron, and other waste into smaller particles, which is convenient for waste treatment and resource reuse.

5、 Development Trends
Large scale mining: With the increase in the proportion of open-pit mining and the adoption of large electric shovels and mining trucks, the size of the raw ore blocks gradually increases. In order to meet this demand, jaw crushers are developing towards large-scale production.
Intelligence: With the popularization and application of technologies such as the Internet of Things and big data, jaw crushers have also ushered in the opportunity for intelligent upgrading. By integrating intelligent devices such as sensors and controllers, real-time monitoring and intelligent adjustment of the crushing process can be achieved, improving the operational efficiency and stability of the equipment.
Environmental Protection: In today’s increasingly strict environmental requirements, jaw crushers still need continuous improvement in noise control, dust suppression, and other aspects. At the same time, measures such as optimizing equipment structure and using environmentally friendly materials are taken to reduce the impact of equipment on the environment, promoting the green development of mining and mineral processing industries.
In summary, jaw crushers have been widely used in multiple fields due to their high efficiency, energy saving, and simple structure. With the advancement of technology and the development of industry, jaw crushers are moving towards large-scale, intelligent, and environmentally friendly directions.
