Description

Vibration jaw crusher
Technical field
The invention relates to a kind of disintegrating machine, espespecially a kind of vibration jaw crusher, its natural building stones that will exploit gained carry out the machinery of broken processing by certain size, and are widely used in the industries such as metallurgy, mine, building materials, chemical industry, coal.
Background technology
Single toggle jaw crusher mainly is comprised of two jaws (sewing jaw and fixed jaw).Sewing jaw periodically moves back and forth fixed jaw, the time and close, the time and separate, make thus that the stone that is contained between two jaws is squeezed, splitting and flecition and fragmentation.Owing to the advantages such as simple in structure, easy to manufacture, reliable operation, easy maintenance are that engineering circles uses very widely.
The movable jaw of single toggle jaw crusher is directly to be suspended on the eccentric shaft, is subject to being partial to the direct driving of axle.The bottom of movable jaw is supported on the rear wall of frame with a thrust plate.So sewing jaw is made reciprocally swinging to deciding jaw on the one hand, can do simultaneously and swing up and down, the movement locus of every bit and different on the movable jaw, the swinging track of each point is to vary continuously to the ellipse of bottom by the top near circle on the jaw, the ellipse that more arrives the bottom is more flat, the horizontal throw of moving jaw is increasing variation the from lower to upper then, therefore not only can play crushing, split brokenly stone, can also play the broken effect of rolling.Because turning to of eccentric shaft is counterclockwise, the direction of motion of each point all is conducive to promote discharge on the moving jaw, so crushing effect is good, percentage of damage is higher, product granularity evenly and be cube more and be fit to hardness building stones in the fragmentation.Because during this class disintegrating machine work, the movement locus more complicated on the movable jaw each point therefore be called complicated oscillating-type jaw crusher, is called for short compound pendulum type jaw crusher (jaw is broken).
The crumbling method of present traditional single toggle jaw crusher all is limited to decide in the crusher chamber that working surface that jaw and moving jaw make up forms.
In other words crusher chamber is interior by the mode of deciding jaw and the formed closed volume of moving jaw and stereomutation, is the main key that produces shattering process.
With regard to modern theory of comminution, need in the process of material crushing constantly to change the orientation between the material particles, with extruding, the shear stress that bears alternation in crusher chamber.In the equal strength particle, those lattice defects are broken with the particle that the shearing force direction overlaps.Material crushing is indoor to be pushed mutually, if apply quantitative pressure to material bed this moment, can make material bed suitably compacting, and make material bear multi-faceted extruding, because the material particles interaction, thereby realize " bed of material pulverizing ".It is less that so-called bed of material pulverizing is based on material particles, and lattice defect is fewer, and intensity is larger, so the large granule of intensity can the broken adjacent little bulky grain of intensity.The so main and not broken crystal broken along the zone between lattice of material itself, the material after the fragmentation has the minimum pulverizing of crossing, thereby has realized " selective crushing " of material, can light broken compression strength between the material of 200~360Mpa.According to theory of comminution, for the broken material of hard difficulty, utilize frequent impact that material is applied huge impact energy and impulsive force, also can reach good crushing effect.

2. the moving simple oscillating motion track of jaw, on the moving jaw every all the circular arc centered by axle is less near the central shaft circular arc, larger away from the central shaft circular arc.Have that crushing efficiency is low, the ratio of reduction is less than 6 shortcoming.
3. move the track that the comprehensive oscillating motion of jaw is followed simply, compound movement produces, the shortcoming of existing composite move: vertical stroke is greater than the level stroke, and lower aside-liner consumption is serious, generally very few use.
4. vibration jaw crusher is symmetrical (horizontal or vertical) arrangement forms of two moving jaws, under the vibratory impulse operating mode, the vibration that the vibration jaw crusher parts bear, impacts the most violently, and the energy of consumption is also large.In addition, strong vibratory impulse process is had relatively high expectations to spring, moving jaw kinetic swing and design bearing, also is the major issue that should solve in the vibration jaw crusher exploitation.

Moving jaw feeding mouth end: Y ' M1=Ecos θ+N 1Cos θ 2-N 2Sin θ 2, X ' M1=Esin θ+N 1Sin θ 2+ N 2Cos θ 2
Moving jaw discharge port end: Y ' M2=Ecos θ+N 3Cos θ 2-N 4Sin θ 2, X ' M2=Esin θ+N 3Sin θ 2+ N 4Cos θ 2
Actual activity jaw 31 feeding mouth ends, discharge port end displacement are the sum total of two kinds of movement locuses, so that the horizontal direction amount of movement of movable jaw 31 discharge port ends is larger than traditional compound pendulum type jaw crusher, increase work efficiency.
That General Oscillation machinery all has is simple in structure, cost is little and the characteristics of less energy consumption, and unstable, the steady-state amplitude of amplitude is adjusted complicated shortcoming when certainly also having the Near resonance oscillating frequency.So suitable vibration ratio is the main key of success or failure of the present invention.
