Simply put, Jaw Crusher Working Principle

Simple pendulum jaw crusher works:

Moving jaw crusher suspension mandrel can be used as swing around the eccentric shaft rotates, the rod up and down reciprocating motion. Two thrust plates driven reciprocating motion, thus promoting the reciprocating motion of the moving jaw do so to achieve fragmentation and unloading. Such double-crusher crank linkage, although the fixed jaw broken by a great reaction force, and its eccentric shaft and connecting rods are Shouli Bu large, so the industry made more mainframe and mid-sized machine, used to crushing hard materials. In addition, the Crusher, the moving jaw on the trajectory of each point is the center of the axis of the arc radius is equal to the distance from such point to the axis, the top of the arc is small, the bottom arc large, crushing low efficiency, the reduction ratio i is generally 3-6. As simple trajectory, it is called a simple swing jaw crusher.
Simple pendulum jaw crusher is simple compact, eccentric shaft driving force smaller pieces; vertical displacement of the movable jaw smaller, less materials processing phenomena of excessive fragmentation, moving jaw jaw plate wear small.
Jaw Crusher Working Principle:
Upper moving jaw hanging in the eccentric shaft directly, as the crank connecting rod, eccentric by the eccentric shaft direct drive, moving the bottom jaw thrust plate support hinge attached to the rear wall of the rack. When the eccentric shaft rotates, the moving jaw on the trajectory of each point of the circle by the hanging point line (radius equal to the eccentricity), and gradually down into the Oval, the more down to the Ministry of the more oval-shaped side, until the bottom and thrust plate connection point for the arc line trajectory. Because of this machinery moving jaw at various points along the trajectory is complex, it is called complex swing jaw crusher.
Compound pendulum jaw crusher, compared with the simple pendulum, and its advantages are: quality of light, fewer components, more compact structure, degree of crushing cavity filled with good material blocks are evenly loaded broken lower jaw to move Mandatory introduction of product discharge, it is higher productivity, compared with the same specifications of the simple pendulum jaw crusher 20-30% higher productivity; material blocks the lower jaw moving up and down rolling movement with a large, easily was the shape of a cube unloaded, reducing the product as simple as tilting the sheet components, better product quality.
Other types of jaw crusher:
1. Hydraulic jaw crusher
2. No grinding jaw crusher
3. The impact of jaw crusher
4. Direct drive jaw crusher
5. Dual chamber jaw crusher
6. Wedge roll jaw crusher

Second-generation jaw crusher hammer a pair of plate surface using only the second reversible counter the wear plate can not be adjusted after the gap, and the third generation of vertical back Hammer can also be turned face down with four directions , and each radial direction can move 30 ~ 50 mm, compared with the second generation of vertical adjustment of back Hammer increase in the number of at least 10 times, and the back plate wear can guarantee the space, therefore, in theory, the board Hammer also increase life expectancy 10 times, that is, a pair of boards can be broken hammer 10 to 15 million tons of clinker, but taking into account other factors, at least 3 to 5 tons is broken for sure. But also through complex manufacturing processes, high resistance to wear-resistant materials fully guaranteed the effective use rate of 70% to 80% or more. Can be seen, although this new variant of the hammer price increased slightly, but its use and the economy overall efficiency is better.
Note: (1) new board began to hammer the situation; (2) board hammer can be used for some time rubbed off the opposite corner of use; (3) after the use of negative plate hammer; (4) When the board using the hammer opposite corners wear, increasing the gap can induce a large plate hammer to ensure the use of space; (5) board hammer wear can turn around and use the gap and then increases; (6) When the liner wear, the board may induce a hammer again to ensure that the use clearance.
