The specific embodiment
Disintegrating machine 10 as shown in Figure 1 comprises 7 breaker drum assemblies 20.Disintegrating machine 10 has first end 21 and the second end 22, and each end is preferably limited by sidewall 23.
Each drum assembly 20 comprises axle 25, and a plurality of band ring gears 30 that separate along axle are installed on it.
Each band ring gear 30 comprises a plurality of crushing teeths 31 that center on the circumference spaced at equal intervals of ring 30.As shown in Figure 4, the number of the tooth 31 on each ring 30 is 5; But what can estimate is that the number of tooth on each ring can be greater or less than 5.Preferably, the number of the tooth 31 on each ring 30 is selected from scope 3-8.
The radial height and the circumferential clearance between each tooth 31 of each tooth 31 of ring on 30 are preferably so selected, and make dark relatively ore hold between the relative tooth 31 that storehouse 35 is formed on adjacent bulging assembly 20.Preferably, each ring 30 on 25 is arranged such that tooth 31 follows discrete spiral path along axle, and so defines the tooth 31 on the adjacent ring 30 on the same axle, makes dark relatively discrete ore hold helicla flute 40 and extends along each axle 25.Preferably, the depth D of groove (radially the bottom of line from the tip of tooth 31 to groove measured) within scope 1: 2 to 1: 3, preferred is about 1: 2.5 with respect to the ratio of the radial height R (measuring from rotating shaft) at tooth 31 tips.
The size and dimension of the tightness degree of adjacent ring 30 and tooth 31 is preferably so selected, and makes helicla flute 40 act on and causes this material to move along the drum axis direction on the material that is positioned at it.
Preferably, the spiral path followed of every row tooth turns over an about angle of 90 ° when its end from the drum assembly when the other end extends.Spiral path from an end of drum assembly to the described angle of other end motion process can less than or greater than 90 °, but preferably less than 360 °.
Preferably, as shown in Figure 1, each drum assembly so arranges, makes that the helicla flute on the bulging assembly 25 extends with opposite rotation direction with respect to the helicla flute on its adjacent drum assemblies 20 along it.
Preferably, as shown in Figure 2, the ring 30 on bulging assembly is axially staggered with the ring 30 on the adjacent drum assemblies 20, between promptly the ring 30 on bulging assembly is positioned a pair of adjacent ring 30 on the adjacent drum assemblies 20 along axis.Thereby this makes tooth 31 on the adjacent bulging assembly can cooperate with utilizing as discussing among our EP0167178 to press the broken nugget of action.
Each drum assembly 20 is preferably driven by individual motor 50, and the latter can for example be electric motor or hydraulic electric motor.With the group of motors 50 that FM represents, each all is arranged to and can rotates the bulging assembly 20 that is associated with them continuously along identical direction of rotation, makes the top of drum assembly rotate towards the second end 22.Shown in arrow FA among Fig. 4.
As shown in Figure 4, adjacent drum assemblies 20 in the FD group (corresponding to the group that is driven by group of motors FM) is along identical direction FA rotation, and a pair of right-hand drum assembly 20 that provides also moves this material by material being contained in its helicla flute 40 interior materials that are positioned at bulging assembly top that press to the second end 22.
Preferably be arranged to along its drum assembly of opposite rotation direction Continuous Drive with the motor 50 that the bulging assembly 20 that closes on the second end 22 is associated.Therefore, latter two drum assembly 120,220 that closes on the second end 22 defines and is similar to the similar twin bulging disintegrating machine of disclosed disintegrating machine among we EP 0167178, wherein the tooth on two bulging assemblies 20 is used for making that the ore between the drum assembly is broken, and impels ore to be broken between drum assembly 20.Arrange that with this oversize lump that arrives the second end is by initiatively broken with the process disintegrating machine.
But what can estimate is that the last breaker drum assembly 20 that closes on the second end 22 also can rotate along the direction identical with feeder drum assemblies.In this layout, oversize outlet (not shown) should be arranged on the second end 22, thereby makes oversize lump discharge from disintegrating machine.
Utilize such layout, this disintegrating machine not only can be as the disintegrating machine at ore breaking ores in the second end 22 motion processes, and can be used as sieve or screening washer, thereby the nugget above preliminary dimension in the filler nugget is removed.
In use, filler is placed on end 21, is positioned on the bulging assembly 20 of this end.
Because rotate along the direction of the second end on the top of the bulging assembly 20 in the FD group, cause material because the effect of tooth 31 is flowed along this total direction.Consider the helicla flute 40 that exists on the bulging assembly, also cause material by right or left-handed the moving axially of the spiral fluted on this drum assembly to indicated direction upper edge drum assembly.
But, when material passes on the next drum assembly 20, cause material to move (because this drum assembly rotates the helicla flute that still has with the opposite rotation direction of helicla flute of previous bulging assembly with identical direction) with opposite axial direction along this drum assembly 20.
Therefore, should be understood that, when material when the second end moves, alternately can be so that material is flowing from bulging assembly width along disintegrating machine when next one drum assembly moves.
Undersized nugget, chip or dust that gap between the adjacent drum assemblies is chosen to allow to be scheduled to are by therebetween.Therefore, by making material flow through out-of-date selectable width along disintegrating machine towards the second end 22, described material can broadly be distributed on the width and length of disintegrating machine, thereby and described material in this distributed process, stirred impelled that undersized material effectively sifts out in the filler from oversize nugget.
Oversize nugget be subjected to the drum assembly 20 the same distribution effect (promptly, move with respect to the broad ways that disintegrating machine replaces in the process that the second end 22 moves at them), but they are subjected to fragmentation by acting on pressing between the tooth relatively on the adjacent drum assemblies in addition.As shown in FIG. 4, wherein nugget LP1 is illustrated in the zone 35 between the relative tooth 31 that just is pressed on the adjacent bulging assembly 20.In this zone 35, crushing action is the anterior 31a of the tooth 31 on the right-hand drum assembly 20 broken result on the back 31b of a pair of tooth 31 on the left side drum assembly, also is broken result on the anterior 31a of the relative tooth 31 of left side and right-hand drum assembly 20.
In order to be implemented in active " biting " nugget LP1 in the zone 35, each tooth 31 preferably has the shape of elongation, described shape has short relatively guide surface 31f and relative long trailing face 31t, make each tooth not only along axle 25 radial projection, and has an initiatively top rake (that is longitudinal axes L of tooth,
ATilt in axle 25 the rotation direction), its degree preferably as shown in Figure 4, the longitudinal axes L of each tooth
AAlong usually extending with the tangent direction of axle 25.
Preferably, guide surface 31f extends back (with respect to rotation direction) away from tip 131, thereby provides the gap at most advanced and sophisticated 131 rear in crushing action.Preferably, in this respect, guide surface 31f defines recess or storehouse portion 132 at crown end 131 rears.This arrangement assists provides initiatively " interlock " for pressing in zone 35, thus and the broken oversize nugget LP1 that is positioned at zone 35.
When the tooth on the right-hand drum assembly 31 rises, it will lift remaining oversize nugget and leave previous bulging assembly 20 and it is moved to next follow-up bulging assembly 20.
Therefore, when filler by the drum assembly when the second end 22 moves, not only undersized material being because the moving down of tooth on the left side of drum 20 of rotation and being impelled by between the drum assembly 20, and also gradual broken in the moving process of the second end at it of oversize nugget.
As mentioned above, the bulging assembly 20 that is positioned contiguous the second end 22 is along opposite direction rotation, and therefore latter two drum assembly 20 be used for the oversize nugget of fragmentation in the mode described in similar we EP 0167178.
As seen the drum in the FD group has tooth 31 thus arranged, make each tooth that rouses upside usually tangentially towards the second end, and the tooth of drum 120 is towards first end 21.Effective interlock is provided like this or has pressed area B R, the latter is bigger than the zone between the bulging assembly 20 of front.
Should be noted in the discussion above that the groove 40 on the bulging assembly 120,220 has opposite rotation direction.Since these drum assemblies along the rotation of opposite direction, this means the material that is positioned on these drums with equidirectional towards a side shaft of disintegrating machine 10 to moving.This is a kind of useful skill, because the function that it provides is to make the oversize material that is not broken as yet discharge (Fig. 1) in the RM position.
Preferably, as Figure 1-3, each drum assembly 20 and the motor 50 that is associated are built into and form independently breaker drum module 60 of part, and described breaker drum module comprises a pair of relative end-wall assemblies 66 of having settled axle 25 of wherein rotating.
Therefore, disintegrating machine 10 is made up by the series of identical module 60 of extending between first and second ends 21,22 and forms.End-wall assemblies 66 is installed on the beam 67 traditionally, and described beam extends along the wherein either side that is positioned at the conveyer 80 under the disintegrating machine 10.
So should be understood that the capacity of disintegrating machine 10 can be at the scene by increasing or reducing module 60 and increase easily or minimizing.This make disintegrating machine capacity with easily with cost effectively mode be configured to specific application.
In addition, should be understood that the interval between the module can easily be regulated, purpose is the interval that changes between the adjacent drum assemblies 20, thereby regulates quantity and the size that can pass through the undersized material between the drum assembly, and adjusting compresses zone 35.
Should be understood that the tooth 31 of different numbers, size and dimension can be arranged on the adjacent bulging assembly 20, thus material from the end 21 performances that when move end 22, change disintegrating machine 10.
Preferably as shown in the figure, breaker bar assembly 100 is positioned under the bulging assembly 120,220, thereby makes ore by further broken to cooperate with it.The breaker bar assembly just has structure easily as us illustrated in any one of the UK Patent Application in the application process 0308933.1 and 0326157.5.
