This series of jaw crushers (jaw crushers) have the characteristics of large crushing ratio, uniform product particle size, simple structure, reliable operation, easy maintenance, and economical operating costs. Jaw crushers are widely used in mining, building materials, In chemical industry, metallurgy and other industries, it can perform coarse and medium crushing operations on various ores, rocks and other materials with compressive strength not exceeding 100%. It is the first choice equipment for crushing ore materials such as ore crusher and gangue crusher.
Jaw type Crusher is mainly used as coarse crusher and secondary crusher in mining, building materials, infrastructure and other departments. According to the width of the feed port, it is divided into three types: large, medium and small. The one with a wider feed port width is a large machine. The jaw crusher has a simple structure, is easy to manufacture, reliable in operation, and easy to use and maintain.
There are two basic types of jaw crushers. There are two types, namely simple pendulum jaw crusher and compound pendulum jaw crusher.
The working principle of simple pendulum jaw crusher is that the motor drives the belt and pulley, and the connecting rod moves up and down through the eccentric shaft. When the connecting rod rises When the connecting rod moves down, the angle between the toggle plates becomes larger, which pushes the movable jaw plate type fixed jaw closer. At the same time, the material is crushed. When the connecting rod goes down, the angle between the toggle plates becomes smaller, and the movable jaw plate becomes smaller. The plate leaves the fixed jaw plate under the action of the tie rod spring, and the crushed material is discharged from the crushing chamber. As the motor continues to rotate, the movable jaw of the crusher does a periodic crushing of the material.
Compound pendulum jaw crusher Principle of folding
The upper end of the movable jaw is directly suspended on the eccentric shaft. As a connecting rod of the crank link mechanism, it is directly driven by the eccentricity of the eccentric shaft. The lower end of the movable jaw is hinged with a thrust plate and supported on the rear wall of the frame. .When the eccentric shaft rotates, the motion trajectory of each point on the movable jaw is determined by the circumferential line of the suspension point (the radius is equal to the eccentric distance) and gradually turns downward into an ellipse. The further toward the lower part, the more deviated the elliptical shape becomes, until the lower part is connected to the thrust plate. The point trajectory is an arc line. Since the motion trajectory of each point on the movable jaw in this machine is relatively complex, it is called a complex swing jaw crusher. We generally use compound swing jaw crushers.
Compared with the simple swing type, the compound swing jaw crusher has the advantages of lighter weight, fewer components, more compact structure, better filling degree in the crushing cavity, and even crushing of the loaded material blocks. The lower end is forced to push out the finished product for discharge, so the productivity is higher, which is higher than that of a simple swing jaw crusher of the same specifications. The material block has a large up and down tumbling motion at the lower part of the movable jaw, and is easy to be discharged in a cubic shape, reducing the It eliminates the flaky ingredients like those in simple pendulum products, and the product quality is better.
