jaw crusher : the work functions and machine types

Jaw crusher in mining , creating supplies, construction department primarily made use of for crushing machine and crushing machine.

Jaw Crusher

Jaw crusher perform component is two jaw plate, one is fixed jaw plate (fixed jaw), vertical (or top rated WaiQing) fixed within the body is former wall, one more is activities jaw plate (dynamic jaw), location, and fixed jaw plate tilt formed below the huge crushing cavity (modest chamber).Activities with the jaws of fixed jaw plate wants to do periodically reciprocating motion, often separate, often approaching.Apart, material into the crushing cavity, finished goods; discharged from Close, make into two pieces of material among the jaw plate by extrusion, bend and fracturing impact and broken.

Jaw crusher according to activities jaw plate swinging diverse methods, can be divided into simple swing jaw crusher (Jane put jaw crusher). Complicated swing jaw crusher (pendulum jaw crusher) and comprehensive swing jaw crusher three kinds.

Jaw crusher operate principle

Dynamic jaw hanging in thoughts shaft, can make wag, eccentric shaft rotates, the connecting rod does vertical reciprocating motion.

Drive two thrust board also do reciprocating motion, therefore pushing move about reciprocating motion, jaws do comprehend breakage and discharging.

This crusher adopts crank double linkage mechanism, though nevertheless suffer many jaws, as well as the crushing counterforce partiality axis and connecting force is just not large, but more than for industrial created mainframes and medium-sized machine, applied in crushing challenging supplies.

In addition, the crusher function, move each and every point on the jaw trajectory is centered mandrels arc radius of arc, the distance is equal to point to axis, the top arc small, lower arc large, crushing efficiency is lower than average, the broken for 3-6. Since trajectory basic, thus calls straightforward swinging jaw crusher.

Jane put jaw crusher compact structure basic, eccentric shaft transmission parts like force small; Because of the dynamic jaw vertical displacement is lesser, processing supplies is small excessive broken phenomenon, dynamic jaw jaw plate wear smaller.

Pendulum jaw crusher perform principle

Dynamic jaw hanging in eccentric shaft directly in the leading, as the crank rod technique by eccentric shaft rods, the eccentric drive directly, the lower hinge connecting dynamic jaw thrust board support to wall frame.When eccentric shaft rotates, the dynamic jaw trajectory of every point on the circumference by hanging point line (radius equal eccentricity), gradual downward into the oval, the more the slant to bottom, oval, until the lower and thrust plate junction arc trajectory.Since the machinery of diverse points on dynamic jaw trajectory of far more complex, so known as complicated swing jaw crusher.

After tilting jaw crusher compared with Jane tilting, its advantage is: top quality is lighter, much less, extra compact structure component, broken lumen filled with degree is very good, with supplies by uniform broken, to block bottom mandatory move jaw is unloading, launch finished greater, than with specifications productivity of Jane put jaw crusher 20-30% greater than the productivity;Material blocks within the lower have larger jaws move up and down movement, a cube tumbling to the shape of, lowering the discharged as Jane tilting items that flake composition, item good quality is greater.
