Abstract
The utility model relates to an ore crusher which comprises a transmission mechanism and a pair of mutually matched cone type crushing rollers (8), (9) which are not arranged in the same center. The utility model is characterized in that the mutually matched outer cone roller (8) and inner cone roller (9) both have the same structure of movable type and the same direction of rotation. One of the breakthrough points of the utility model is that the inner and the outer rollers rotate simultaneously, synchronously, in the same direction and at the same speed, the phenomenon of sliding friction existing between the crushing roller and ore is completely eliminated, compressive stress is sufficiently used, so work efficiency is raised. Simultaneously, ore discharging speed can be accelerated by the centrifugal force produced by making use of the holding of ore by the inner and the outer rollers when rotating, the condition that the discharge of ore depends on the falling of ore by gravity is altered, and the phenomenon of clogging of an ore discharging port is avoided.
Description
The utility model is a kind of ore crusher, and it comprises the circular cone type breaker roll that cooperatively interacts of transmission mechanism and a pair of non-concentric setting.
Ore is pulverized and is divided into fragmentation and grinds two classes.The former mostly is jaw formula, hammer, roll-type etc. by used legacy equipment, and its broken granularity is in mm.The used legacy equipment of the latter mostly is ball milling or rod milling etc., and its broken granularity is in μ.
Because the restriction of means of testing still can not be made quantitative description to the mechanical process of ore reduction at present.But the general attached suggestion of broken industry with German scholar, that is: 1. legacy equipment is used for fragmentation, and its effective power is no more than 6%, and the effective power of attrition process is no more than 0.6%; 2. in many broken means such as shearing, extruding, bending, strike, rubbing, make ore reduction the most effective with fashion of extrusion.Make ore reduction not only avoid the loss of idle works such as friction, impact, vibration, noise with fashion of extrusion,, thereby can greatly improve operating environment also because this operating type has the advantage of depositing dust noise reduction.
Based on above-mentioned viewpoint, current broken industry one is to try to explore efficient new tool, new architecture, more abundant comprising the means performance that makes attrition crushing; The 2nd, reduce mill feed size, promptly strengthen the ratio of reduction of disintegrating machine, the part work that can only use power 0.6% in the ball mill is taken outside the grinding machine, the 6%(one that can bring up to power utilization says 30%).These 2 all is the target that the novel ore crusher of current research is pursued.
In current many disintegrating machines, can utilize the type of fashion of extrusion breaking ores to comprise pair roller type, bevel-type and rotating disk type disintegrating machine, wherein the action principle of bevel-type and rotating disk type is identical, we can say that also bevel-type and rotating disk type represented domestic and international large reduction ratio, efficient advanced type and advanced technology.
Below just approaching with the utility model prior art--the structure and the principle of cone crusher are described:
It is to have the inside and outside awl roller of decentraction to constitute crusher chamber, its outer cone roller is a fixed roll, and the swing campaign is done with rotation speed n in the axle center of inner cone roller, and simultaneously the inner cone roller is done gyration around himself axis with rotation speed n 2 again, but n2 is opposite with the direction of n, according to practical experience n2=n/20.Though therefore this disintegrating machine can obtain the bigger ratio of reduction, has sliding phenomenon between breaker roll and the ore, compression is utilized insufficient, is difficult to reduce effectively working-noise.Because outer cone does not change (fixing),, also easily produce clogging simultaneously, influence the further raising of productivity ratio by the deadweight discharge.
The utility model purpose provides a kind of structure more scientific and reasonable with regard to being to overcome above-mentioned weak point of the prior art, and compression is more made full use of, and have that the ratio of reduction is big, work efficiency is high, noise is low, discharge ore crusher smoothly.
The utility model purpose can adopt following measure to realize:
It is made up of ore crusher of the present utility model the circular cone type breaker roll that cooperatively interacts of transmission mechanism and a pair of non-concentric setting; The inside and outside two awl rollers that it cooperatively interacts are the dynamic formula structure, and rotation in the same way.
The mating surface of the inside and outside two awl rollers in the utility model is curved-surface structure; The periphery of inside and outside two awl roller discharge gates is tangent with two concentric circles spheres respectively, and the centre of sphere and inside and outside two awl roll axis meet at a bit altogether; The rotation of inner cone roller is to realize by the vertical shaft that combines with it; The outer cone roller is by being arranged on gear ring on its outer wall and the gears engaged in the transmission mechanism together; The summit of the reference cone angle of the bevel gear that is installed in the bevel gear on the vertical shaft that combines with the inner cone roller and is meshed with it meets at the intersection point of two awl roll axis.
The utility model is compared with the cone crusher of prior art, one of its break-through point be exactly inside and outside roller simultaneously in the same way, synchronously, rotate with speed.So just can eliminate the sliding friction that exists between breaker roll and ore in the prior art fully, make compression be able to sufficient utilization, thereby improved work efficiency widely; The centrifugal force that the clamping ore is produced when utilizing inside and outside roller to rotate simultaneously quickens the discharge process, has changed to lean on the situation of material from gravity drop discharge in the prior art, has avoided the discharging opening phenomenon of blocking, has further improved production efficiency.
The drawing of accompanying drawing is described as follows:
Fig. 1 is a fundamental diagram of the present utility model.
Fig. 2 is a front view of the present utility model.
Fig. 3 is the relative position relation figure between the inside and outside awl roller among Fig. 2.
The utility model is done with detailed description below with reference to embodiment (accompanying drawing), but does not limit the utility model.
As shown in Figure 1, the crusher chamber formed of the circular cone type breaker roll (8) (9) that cooperatively interacts by a pair of non-concentric setting in the utility model is divided into slack strand and compression section.In slack strand, inside and outside two gaps of awl between the rollers from large to small in rotational direction, ore (17) is moved down; In the compression section, gap in rotational direction produces the extruding to ore from large to small, makes it to be broken for fritter; In the crushing operation, inside and outside two awl roller clampings all the time ore and are rotated synchronously, have avoided the sliding friction between ore and the breaker roll, have reduced impact, vibration and noise.Centrifugal force when ore rotates has synchronously also been accelerated discharge velocity, and the expulsion force of ore strengthens along with moving down of ore.This just not only helps improving the productivity ratio of disintegrating machine, has also avoided the clogging in the operation.
As Fig. 2, shown in Figure 3, the circular cone type breaker roll (8) (9) that cooperatively interacts of its a pair of non-concentric setting of driving by transmission mechanism with by transmission mechanism of ore crusher of the present utility model is formed; The mating surface of outer cone roller (8) and inner cone roller (9) is curved-surface structure, and the periphery of inside and outside two awl roller discharge gates is tangent with two concentric circles spheres (12) (13) respectively, and the centre of sphere and inside and outside two awl roll axis (14) (15) meet at a bit (16) altogether.
The inside and outside two awl rollers (9) (8) that cooperatively interact in the utility model are the dynamic formula structure, and in the same way, synchronously, (purpose is not have friction in the crusher chamber and rub in order to make with speed rotation, to reach the maximum energy-saving state, the fragmentation of its ore mainly is to bore the eccentric crusher chamber that forms between rollers by inside and outside two of non-concentric installation to realize).Its drive path as shown in Figure 2, power source passes to driving shaft (2) via belt pulley (1), again via paired meshed bevel gears (3) (4), (5) (7) with dynamic branch to inner cone roller vertical shaft (6) and outer cone roller power transmission shaft (10), the gear ring that is positioned on roller gear (11) and the outer cone roller (8) on the power transmission shaft (10) meshes together, and inner cone roller vertical shaft (6) is to drive by the bevel gear (5) that is installed in the bevel gear (7) on the vertical shaft and be meshed with bevel gear (7); The summit of the reference cone angle of bevel gear (7) and the bevel gear (5) that is meshed with it meets at the intersection point (16) of two awl roll axis.Inner cone roller (9) directly and vertical shaft (6) combine.
Certainly, inside and outside two awls in the utility model rollers time the, in the same way, rotate except that adopting above-mentioned drive path realizes with speed also can adopt double dynamically to drive inside and outside two awl rollers respectively and rotate; According to the different requirements of ore reduction, inside and outside two awl rollers are guaranteeing under the prerequisite of rotating in the same way, also asynchronous (different speed are rotated) in addition.
According to thinking of the present utility model, design and manufactured experimently model machine, entrust Zhengzhou Research Institute of Mechanical Engineering of dynamo-electric portion to test.Energy consumption index and pair roller type, circular cone type and execute relatively seeing attached list of disk crusher.Although model machine is thoughtful not enough in some place of technology and design aspect, it has shown compellent superperformance, has enumerated area ratio and energy loss-rate in the table.
Press the area theory: during broken material, required merit is directly proportional with the new area of generation, and it is 1 regular hexahedron that the ore before broken is reduced to the length of side, and its surface area is A0=6
Broken back is the regular hexahedron of 1/n for the length of side, and its surface area is
An＝〔6（1／n）
2〕·n
3＝6n
During ratio of reduction i=n, the new area of generation is
△An＝An－A0＝6（n－1）
During ratio of reduction i=m, the new area of generation is
△ Am=6(m-1) the two area is than eA=(n-1)/(m-1)
The energy loss-rate of the two should be eE=En/Em=(n-1)/(m-1)=eA
If eE＜eE then show that first kind of energy consumption index that produces the disintegrating machine of ratio of reduction i=n is better than producing in second disintegrating machine of ratio of reduction i=m is by finding out that the energy consumption index of new type crushing machine of the present utility model has reached advanced level in the table.
(apart from disintegrating machine 1m, apart from the high 1m in ground) eight measuring point noise mean values are 78.0375dB during idle running after tested, are 81.9875dB during operation, and the two differs 3.95dB.Five measuring point mean value of amplitudes of vibration-testing are 0.0112mm, and vibration velocity mean value is 3.56mm/s, and these indexs have all reached advanced level.After having taked corresponding technical measures, the noise figure when idle running and load also can reduce significantly.
