Description
Technical field
The present invention relates to a kind of crushing operation facility, especially the excitation type bobbing machine belongs to the crushing mechanism technical field.
Background technology
Broken and grind operation and be widely used in metallurgy, mine, building materials, chemical industry numerous areas, but energy consumption is high, and it is significant how to reduce broken the energy consumption of grinding cargo handling operation.Through broken mill flow process, the particle diameter of mineral can be from reducing to 0.088mm more than the 1000mm, total ratio of reduction reaches more than 10000, and the ratio of reduction of broken link less (general＜50) but efficient is higher grinds the ratio of reduction big (〉=200) of link and relative efficiency is lower, and statistics shows that energy loss-rate broken and that grind is about 1: 9, therefore, the development of a theme direction in current crushing technology field is the ratio of reduction that increases reduction stage, reduces the ratio of reduction of reduction stage, thereby reduces whole flow process power consumption.Main means are exactly the in small, broken bits and ultra-fine broken disintegrating machine of extensive use.
Traditional disintegrating machine crowded broken, the crushing pattern is difficult to competent in small, broken bits and ultra-fine broken operation, and utilizing the relative vibration of rigid body then is the ideal equipment that realizes super fine crushing to the vibro-crusher that mineral apply high-frequency percussion power.Its advantage is: the ratio of reduction big (can reach more than 20), the product granularity ratio of reduction thin, that can make reduction stage increase 10 times; And because the striking frequency height, the variation of width of discharge opening is little to the product granularity influence, and is insensitive to the wearing and tearing of liner plate; Can realize selective crushing and interlayer fragmentation, therefore than power consumption, lower than the steel consumption; Vibration force is non-rigid power, so the difficulty material that minces is gone into machine and can not damaged machine etc.The vibro-crusher of multiple different structure form has been proposed at present, both at home and abroad.
Russia changes quadric chain into inertia vibration generator on the basis of two moving jaw disintegrating machines, develop into the two moving jaw crushers in single chamber.But because the width of discharge opening of jaw crusher in small, broken bits is less, the unit treating capacity is lower, can increase the area of discharge gate by adopting double cavity structure, thereby increase the unit treating capacity, has occurred the double-cavity jaw crusher of various ways in recent years.Chinese patent 94246627.6 disclosed a kind of " two-chamber vibration jaw crusher " is exactly one of them, it connects the fixedly connected elasticity that replaces with of the moving jaw upper spindle of simple pendular jaw crusher, but still reservation main axle structure, the bottom dress eccentric activator of moving jaw, jaw is swung, thereby the material in the chamber, the left and right sides is pulverized.But broken zone of body and broken direction lack spring constraint because its master shakes, and do not produce necessary vibration restoring force, and effect in small, broken bits is not ideal enough.
Vibration kibbler roll (ZL 94246606.3), it is to allow roller freely-movable in crusher chamber of eccentricity excitation, might cause the discharging-material size instability but its problem is exactly the undue freely-movable of roller.Vibration roll-type screening crusher (ZL 94246605.5), roller is that perfect elasticity is connected with frame on the one hand, roller is dither under eccentricity excitation, and material is impacted; On the other hand, test sieve is equipped with in the roller bottom, and granularity is discharged by sieve aperture less than the particle of sieve aperture, has guaranteed the granularity of product, but the wear problem of sieve is outstanding.
But, still the coming with some shortcomings of above-mentioned plane vibration class disintegrating machine: the one, underuse bed of material fragmentation, improve crushing efficiency; The 2nd, do not utilize resonance, further improve capacity usage ratio.
Summary of the invention
