Hammer crusher working principle

Generally matched the equipment fan classifier, the product through the fan blowing crusher, hammer crusher inside the product and then follow the wind blow hammer smash classifier, grading machines to grade the products, qualified is the product; unqualified failure to enter into the crusher hopper and then to smash the movable jaw and then hoisted the 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.
