Different types of jaw crusher principle Detailed

Crushers that are several points?
Commonly used machinery has broken jaw crusher, impact crusher, gyratory crusher, cone crusher, roll crusher, hammer crusher and Vertical Shaft Impact Crusher and so are several.

Jaw plate for squeezing and bending the material, crushing or hardness of the material in a variety of pieces of broken machinery. The broken body from the fixed jaw plate and movable jaw plates, jaw plates close to the time when the two materials incurs broken jaw plate when the two left the nesting population is less than a block from the bottom of the discharged material. It's crushing action is carried out intermittently. This crusher due to simple structure, reliable and hard materials can be broken, etc. and is widely used in mineral processing, construction materials, silicate and ceramic industries.

To meet the requirements of the different marker size and compensation jaw plate wear, but also the addition of nesting population adjustment device, usually in the seat and the rear frame bracket to put shims between the plus or the wedge. However, in order to avoid the replacement of broken parts to affect production, but also can be used hydraulic equipment to achieve security and adjustment. Some jaw crusher is also used directly to drive the hydraulic jaw plate move to complete the material crushing action. These two types of hydraulic transmission equipment jaw crusher, often referred to as the hydraulic jaw crusher.

The structure of jaw crusher main frame, eccentric shaft, a large pulley, flywheel, moving jaw, side guard, elbow board, elbow board seat, adjust gap screw, reset spring, the fixed jaw plate and the activities of the jaw plates and other components , which bracket also play a role as insurance. This series of jaw crusher way to move music compression type, motor-driven belt and pulley, the eccentric shaft to move the jaw up and down movement, when the moving jaw to rise between toggle plate and moving jaw angle becomes larger, thus promoting the moving jaw plate close to the fixed jaw plate, while the material is squeezed, rubbing, grinding, such as multiple broken; when moving the jaw down, the toggle plate and moving jaw angle between, moving jaw plate rod, leave the action of the spring fixed jaw plate, this time under the broken material from the crushing chamber discharge port, with the mobile jaw crusher motor for continuous rotation of the crushing and periodic discharge, to achieve mass production.
Introduction of different types and type theory, the jaw crusher (broken jaw) is widely used in industrial and mining enterprises, it is because it is relatively simple structure, and has large-scale models complete. Jaw Crusher (broken jaw) is mainly As a (rough and broken in pieces) with broken machinery. It can and mineral processing equipment, ancillary equipment, sand and gravel can also be used alone. Existing jaw crusher (broken jaw) pressing the jaw movement characteristics, are divided into simple swinging type jaw crusher, complicated swing jaw crusher and mixed swing jaw crusher three forms.

 Simple swing-type (simple pendulum type) jaw crusher
Simple pendulum jaw crusher and jaw set jaw, fixed jaw fixed to the front of the rack wall, moving the jaw is hanging mandrel. When the eccentric shaft rotates, the drive rod up and down reciprocating motion, so that the two thrust plates also come as a reciprocating motion. Through the thrust plate role in promoting the suspension in the suspension axis reciprocating jaw motion. When put to the fixed jaw jaw, the jaw cavity material falls mainly by the compression plate and jaw crushing. When moving away from the fixed jaw when the amount placed, the material has been crushed under the action of gravity, the lower jaw cavity free discharge port unloading. Jaw crusher which work is intermittent, grinding and unloading process in the jaw cavity alternately. This crusher work, the points are moving jaw hanging on the center axis, simply for the swing arc. As the trajectory is relatively simple, it is called a simple swing jaw crusher, referred to as simple pendulum jaw crusher.

Swing-type complex (compound pendulum type) jaw crusher
Jaw hanging in the eccentric shaft directly by the bias of the direct drive shaft. Moving the bottom jaw thrust plate with a support wall in the rear rack. When the eccentric shaft rotates, moving the jaw while on the fixed jaw for the swing back and forth, and also set down a great degree of upper and lower jaw movement. Every point on the jaw are not the same trajectory, the movement of the top constraints by the eccentric shaft, the trajectory is close to the arc, moving the jaw in the middle part of the trajectory of elliptic curves, the more the more oval near the bottom of a longer length. Since this type of crusher work, moving the jaw on the trajectory of each point is more complex, it is called complex swing jaw crusher, referred to reciprocate Jaw Crusher (broken jaw). http://www.infostonecrusher.com
