Description

A kind of zero load loading slide system jaw crusher

Technical field

The invention belongs to mining machineries, more particularly, to a kind of ore crusher.

Background technique

Jaw crusher is commonly called as that jaw is broken also known as tiger mouthful, form crushing chamber, simulation animal by dynamic two pieces of jaws of jaw and quiet jaw Two jaw movements and complete the crusher of material crushing operation, be widely used in mine smelting, building materials, highway, railway, water conservancy and Various ores and bulk materials is broken in the industries such as chemical industry, and the maximum compression strength for the material that is broken is 320Mpa.

The outer Crusher nickname Hubei Province literary fame Jaw of Chinese name jaw crusher is broken, tiger mouthful, most common ore crusher It is divided into single pendulum jaw, physical pendulum jaw, common jaw crusher there are two kinds of duplex plate and single bracket, the former moves at work Jaw only makees simple arc swing and is also known as simple swing jaw crushing apparatus, and the latter also makees fortune up and down while making arc swing It is dynamic.

Domestic jaw crusher manufacturing firm technical level difference is very greatly different, has the product of a small number of producers advanced close to the world Level, and the product of most of producers gap compared with advanced international standard is larger, jaw crusher frame accounts for overall mass Ratio is very big, wherein casting rack accounts for about 50%, welding stand accounts for about 30%, and external jaw crusher is all welding stand, even Dynamic jaw also uses welding structure, and jaw crusher is developing direction using welding stand, and domestic jaw crusher frame structure is set It counts there are many unreasonable examples, reason is exactly not remove arrangement reinforcing rib by crusher actual loading situation,

In recent years, with the increase of opencast mining specific gravity and the use of large excavator, large-scale mine automobile, And the ore fragmentation that opencut transports ore-breaking plant to reaches 1.5 ~ 2.0 meters, simultaneously as the grade of tcrude ore reduces increasingly, Want to keep the original production capacity in dressing plant, the yield and muck amount of tcrude ore, therefore jaw crusher must be greatly increased Develop to large-scale direction, currently, the jaw crusher of the maximum specification of foreign-made is: letter pendulum is 3000 × 2100 millis Rice is 1800 millimeters to nugget degree, when production capacity is 1100 tons/platform；Physical pendulum is 2100 × 1670 millimeters, and gape is At 355 millimeters, when production capacity is 3000 tons/platform.

With the appearance of impact-resistant large-size rolling bearing, has replace letter pendulum broken using single toggle jaw crusher both at home and abroad The trend of machine, this is because the former improves 30% compared with the latter's production capacity in the comparable situation of condition；In the two production capacity When identical, the former is than the latter weight saving 20% ~ 30%.But the configuration aspects of single toggle jaw crusher are there is also certain problems, Wait Improvement.

It is to be appreciated that in recent years due to the raising of Chinese large-sized rolling bearing material and the needs of underground coarse smash equipment, The single toggle jaw crusher trend that also oriented large-scale direction is developed, currently manufactures experimently 900 × 1200 physical pendulum crushers, with setting The enlargement of standby specification, the adjustment device and safety device of general jaw crusher must use new mechanism, therefore, currently Another trend of jaw crusher development is exactly that gape uses hydraulic adjustment mechanism, is not only simple rapidly, and at work It can according to need and be adjusted at any time；Meanwhile the safety device of the excess load of machine is also using hydraulic mechanism, to reach peace It is complete reliable, also do not damage thrust plate, and after troubleshooting, machine recovers immediately work, both at home and abroad all greatly develop it is this Hydraulic jaw crusher, China have produced 900 × 1200 hydraulic simple pendular jaw crushers, and in Laiwu iron deposit and Roots's iron ore Put into production use, production practices prove, the insurance institution of hydraulic jaw crusher and adjustment mechanism, reached security insurance and Purpose easy to adjust, all right, the deep welcome by post worker.

In terms of the crushing efficiency for improving jaw crusher, in addition to making local improvement in the structure of existing equipment, e.g., increase Add crushing chamber height, improves production capacity；Reduce gape, increases reduction ratio；Increase dynamic jaw swing speed, it is raw to improve equipment Production capacity power and other than improving production quality, currently, the new structural crusher of examination is all grinding in each state, e.g., impact jaw crasher, The jaw crusher of double acting jaw and hydraulicdriven jaw crusher etc..

The working portion of jaw crusher is two pieces of jaws, first is that fixed jaw, vertical or upper end omits flare and is fixed on machine On body antetheca, another is sewing jaw, and position inclination forms up big and down small crushing chamber with fixed jaw.Sewing jaw is opposite Fixed jaw does periodic reciprocating motion, when and separate, when and it is close, when separating, material enters crushing chamber, and finished product is from lower part It draws off；Close to when, be squeezed the material between two pieces of jaws, bending and slabbing action and be crushed.

Jaw crusher is different according to the swing mode of sewing jaw, can be divided into simple swing type jaw crusher, answer Miscellaneous swing type jaw crusher and comprehensive three kinds of swing type jaw crusher.

For jaw crusher, although structure type is different, their working principle is substantially similar , only in brief difference makees week to fixed jaw when swing jaw surrounds suspended axle to the motion profile of dynamic jaw The reciprocating motion of phase property, when and close to when and leave, just when swing jaw is close to fixed jaw, the mine that is between two jaws Stone is crushed, cleaved and is bent the synergy to fracture and is crushed；When swing jaw leaves fixed jaw, it has been crushed Under the effect of gravity, the gape through crusher is discharged ore.

Single pendulum jaw principle: dynamic jaw is suspended in mandrel, can be swung, and when eccentric shaft rotates, connecting rod does past up and down Multiple movement, drives two pieces of thrust plates also to move reciprocatingly, so that dynamic jaw be pushed to do bilateral reciprocation, realizes broken and discharging, Such crusher uses crank-double-connecting-rod mechanism, although receiving very big broken counter-force on dynamic jaw, and its eccentric shaft and connecting rod Stress is little, so industrial be made mainframe and medium-sized machine more, for the material of crushing hard, in addition, this crusher work When making, every motion profile is all the circular arc centered on mandrel on dynamic jaw, and arc radius is equal to the distance of this to axle center, Upper end circular arc is small, and lower end circular arc is big, and crushing efficiency is lower, and reduction ratio is generally 3-6, since motion profile is simple, therefore claims letter Single oscillation jaw crusher, simple pendular jaw crusher is compact-sized simple, and the driving members stress such as eccentric shaft is smaller；Since dynamic jaw hangs down Straight displacement is smaller, and when processing the phenomenon that material rarer overcrushing, the abrasion for moving jaw jaw is smaller.

Compound pendulum type jaw crusher principle: dynamic jaw upper end is hung directly from eccentric shaft, the company as crank link mechanism Bar is directly driven by the bias of eccentric shaft, and the lower end of the dynamic jaw thrust plate that is hinged supports on the rear wall of rack.When eccentric shaft revolves When turning, the motion profile of each point is the circumference by hitch point on dynamic jaw, becomes ellipse gradually downward, more to the lower part, oval Shape is more inclined, is circular arc line until lower part connect the locus of points with thrust plate, due to moving the motion profile of each point on jaw in this machinery It is more complicated, therefore referred to as toggle-type jaw crusher.

Compound pendulum type jaw crusher compared with simple pendulum-type, its advantage is that: lighter weight, component is less, more compact structure, Full level is preferable in crusher chamber, and filled material block is uniformly crushed, and is moved the mandatory release finished product discharging in jaw lower end, therefore Productivity is higher, and the productivity than the simple pendular jaw crusher of same specification is higher by 20-30%, and material block has larger in dynamic jaw lower part Tumbling motion up and down, be easy to draw off in the shape of cube, in design, dynamic jaw and determine jaw crushing shell should tooth peak to tooth Paddy, in this way, there are also flecition, material is easier to be crushed, in order to reinforce brokenly when broken to material other than having squeezing action The service life of slashings, the crushing shell of middle-size and small-size crusher are designed to shape symmetrical above and below, and adjustable head makes after the abrasion of lower part With；The crushing shell of large-scale jaw crusher is designed to mutually symmetrical with several pieces, uses, breaks to exchange crushing shell after wearing The material of slashings can select white cast-iron, and white cast-iron hardness is larger, wearability is preferable, source is easy, cheap, disadvantage That property is crisp, easily snap off, service life it is short, in order to improve the service life of crushing shell, material uses the manganese steel containing 12% or more manganese More preferably, the most commonly used is ZGMn13, and the toughness of manganese steel is preferable, although hardness is not high, about 210HB, and, because having cold add The characteristics of work is hardened, can constantly be reinforced under pressure, therefore constantly abrasion is continually strengthened again at work, until wearing up to It cannot use and just scrap, manganese steel will be by water-tenacity treatment after being crushed plate casting, and the operation of water-tenacity treatment is generally identical as quenching, It is heated to being quickly cooled down in water after 1000~1100 DEG C the manganese steel crushing shell come is cast out, can be obtained after water-tenacity treatment To uniform metallographic structure, and metallographic structure is made to be fixed up, avoids naturally-occurring phase transformation in use and make degradation, The shortcomings that manganese steel is that price is more expensive, but totally considers from service life, cost etc., and ZGMn13 uses the longevity than white cast-iron Life is long, at low cost.
