With the continuous development and innovation of the mining machinery industry, as the main crushing equipment of mining machinery, the jaw crusher has also continued to improve its structure and improve its crushing technology. Jaw crushers have become the main force in the mining machinery industry.
The reason why it is called a jaw crusher is that the main working parts of a jaw crusher include jaws. One is a fixed jaw, referred to as fixed jaw, which is vertically fixed on the front wall of the machine body, and the other is a movable jaw, referred to as movable jaw. The jaws are inclined to form a large and small crushing cavity with the fixed jaw. When the jaw crusher is working, the movable jaw is suspended on the eccentric shaft and can swing left and right. When the eccentric shaft rotates, the connecting rod reciprocates up and down. The two thrust plates are driven to reciprocate, thereby pushing the movable jaw to reciprocate left and right to realize crushing and unloading.
The above is a relatively simple working mode of the jaw crusher . The working principle of the compound pendulum jaw crusher is similar. The upper end of the movable jaw is directly suspended on the eccentric shaft as the connecting rod of the crank connecting rod mechanism. Driven, the lower end of the movable jaw is hinged and supported on the rear wall of the frame with a thrust plate. When the eccentric shaft rotates, the movement trajectory of each point on the movable jaw is from the circumferential line of the suspension point (radius equals to the eccentricity), and gradually becomes an ellipse downward. The locus of the connection point is a circular arc. Because of the complicated movement trajectory of each point on the movable jaw of this kind of machinery, it is called a complex swing jaw crusher.
The working principle of the jaw crusher gives it a great advantage when crushing materials. It has a lighter weight, fewer components, a more compact structure, a better filling degree in the crushing cavity, and evenly crushed materials. The lower end of the movable jaw is forced to discharge the finished product, so the productivity is higher, which is 20-30% higher than the productivity of the simple pendulum jaw crusher of the same specification; the material block has a large up and down movement under the movable jaw, which is easy It is discharged in the shape of a cube, reducing the flake-like ingredients like in the simple pendulum product, and the product quality is better.
