Jaw crusher is a type of crushing equipment for reducing different materials into smaller sizes in mining, metallurgy, chemical, construction, etc. industries. It is also known as the primary jaw crusher since usually used in the first stage of coarse crushing.
The material which the jaw crusher deals with is large. The rock reduced by jaw crusher is ready for impact crusher and cone crusher to do the medium and fine crushing. Jaw crusher is currently the most common crushers for sale in the world. Equipped with high-manganese-steel jaw plates, it can crush ores, rocks, steel slag and other hard materials.
It can be used in cement plants, quarries, stone materials plants, coal processing plants, highway construction, road and bridge aggregates, concrete mixing plants, steel mill, water conservancy projects, construction waste recycling, and other industries.

Jaw Crusher For Sale
SC series jaw crusher is a new generation jaw crusher developed with the introduction of European technology. Compared with a similar type, its output is high, energy consumption is low, the structure is simple, and it is the preferred equipment for crushing various kinds of rocks.
SD European jaw crusher is a new type that has been developed based on introducing advanced jaw crusher technology from Europe and America.SD European Jaw Crusher is suitable for crushing ores, rocks, slag and other materials with compressive strength not higher than 300Mpa.
PE jaw crushers are coarse and medium crush and widely used in the material which compressive strength below 320Mpa. It has the feature of a large crushing ratio, uniform product size, solid structure, stable work, easy maintenance, low operating costs.
Working principle of jaw crushers
The motor drives the belt and belt wheel to move the movable jaw up and down through an eccentric shaft. When the movable jaw rises, the angle between the toggle plate and the jaw becomes larger, thus driving the movable jaw plate towards the fixed jaw plate. At the same time, the material is crushed or split to achieve the purpose of crushing. When the jaw goes down, the angle between the toggle plate and jaw decreases.
Under the rod tension and spring action, the moving jaw plate leaves the fixed jaw plate. At this time, the crushed material is discharged from the mouth of the crushing chamber. With the continuous rotation of the motor, the crushing motor jaw makes a periodic motion to crush and discharge materials, realizing mass production.
Types of jaw crushers
According to the moving jaw mechanism, the jaw crushers are categorized into single toggle and double toggle.
Double toggle jaw crusher
A double toggle jaw crusher has two shafts and two toggle plates. When it works, the moving jaw only involves arc swing motion.
Single toggle jaw crusher
A single toggle jaw crusher has one shaft and one toggle plate. The eccentric shaft is on top of the moving jaw allowing the moving jaw to move in arc swing and up down at the same time. A single toggle jaw has a higher crushing ratio than a double toggle jaw crusher.
According to the top opening size, jaw crushers can be divided into large, medium and small types.
Main parts of jaw crushers
The frame is a four-walled rigid frame with upper and lower openings. It is used to support the eccentric shaft and bear the reaction force of the crushed materials. It is generally cast with cast steel as a whole to get sufficient strength and rigidity.
fixed and movable plate form a crushing chamber and finish crushing ores by compression.
Toggle plates, the eccentric shaft, and the flywheel. These are core components of jaw crushers that generates the action of the jaw to break the rock.
How to choose the right jaw rock crusher?
When choosing a suitable jaw rock crusher, first considering the different applications. Generally, there are stationary crushers or mobile crushers with tires or tracks. Another important factor is the requirements of output and grain size. Furthermore, consider comprehensive aspects.
- Good usability
The ability to meet the requirements of the production process, strong adaptability, easy use and operation, advanced technical performance, high production efficiency, and easy to match the jaw crusher with related equipment.
- Good reliability
Under the condition of fully exerting its high functions still performs reliable working accuracy, low failure rate, high attendance rate, and long average life.
- Good maintainability
Refers to equipment with reasonable structure, a high degree of standardization and generalization of parts, and good interchangeability, which is convenient for inspection, testing, and maintenance.
- Good economy
Refers to the production process equipment consumes less energy, low maintenance costs, more economical life cycle operating costs, and good overall economic benefits.
