Definitions
- the present invention relates to vibrating cone crushers in which the material is crushed between a cone and a frustoconical ring surrounding the cone, the axes of the cone and of the ring being vertical, and comprising an annular frame carrying said ring, which is fixed in the central opening of the chassis, and a device capable of generating circular vibrations in a horizontal plane, a support for the cone, and several tie rods connecting the chassis and the support for the cone, the connections between the ends of the tie rods and the chassis , respectively, the support of the cone, being designed to allow relative horizontal movements of the chassis and the support; the assembly constituted by the chassis, the organs which it supports, the cone and its support, rest on a frame or on the ground by means of elastic organs: springs or rubber damping pads.
- the device for vibrating constituted for example by unbalanced shafts with a vertical axis, generates not only horizontal vibrations of the chassis carrying the ring and of the cone support, when the shredder is in operation , but also vertical vibrations whose amplitude increases from the center to the periphery of the mill.
- These vertical vibrations have the harmful consequences of modifying the flow of materials in the grinding chamber, and of generating stresses detrimental to the mechanical strength of the parts of the crusher, these stresses due to vertical accelerations being all the more important as the grinder is bigger; these vertical vibrations can also be transmitted to the building or the foundations which is annoying and sometimes even dangerous.
- These vibrations also make the process unstable (pulsations at low frequency of the passing flow and of the power absorbed) by the coupling effect between the flow of materials in the chamber and the vertical vibrations.
- the object of the present invention is to eliminate these drawbacks by eliminating or at least by appreciably reducing the vertical vibrations which disturb the operation of these mills.
- the mill object of the present invention is characterized in that the center of gravity of the assembly constituted by the chassis and the members which it supports, and the center of gravity of the cone and its support are in the plane of forces vibrations generated by the vibration setting device or in the vicinity thereof. More precisely, these centers of gravity must remain permanently inside a fictitious sphere centered on the point defined by the intersection of the vertical axis of the cone with the action plan of the vibratory forces when the device is at rest, and with a diameter equal to 15% of the maximum diameter of the cone. By realizing this condition, one avoids exerting on the frame carrying the ring and on the support of the cone tilting torques generating vertical vibrations.
- the chassis comprises a skirt surrounding the support of the cone and optionally provided with weights, and a heavy cap is fixed on the top of the cone.
- the elastic members supporting the crusher can be interposed between the bottom of the skirt and the frame or the foundations, the support of the cone being suspended from the chassis by means of the tie rods.
- Other elastic members can be placed between the skirt and the support of the cone or between the latter and the frame or the foundations.
- the elastic members supporting the mill can be placed between the support of the cone and the frame or the foundations, other elastic members being placed between the skirt and the support of the cone.
- the cone is rotatably mounted on a vertical shaft fitted in its support. To allow the height of the cone to be adjusted, it can be rotatably mounted, by means of bearings, on a sleeve mounted on the shaft so that it can slide along the latter.
- the shaft and the sleeve will be shouldered, an airtight annular chamber being provided between the two shoulders and a channel pierced in the shaft making it possible to bring a liquid under pressure into said chamber to lift the cone or evacuate it. let the cone descend.
- the chassis may consist of a bottomless tank in which the ring is held by appropriate means and which is provided with an annular base on which the vibration device is mounted, the skirt being fixed by its upper end on the edge of the base.
- the vibration setting device will advantageously consist of unbalanced shafts with a vertical axis mounted on said base, each shaft comprising two unbalances arranged on either side of the base so that the vibrational forces generated by the rotation of the trees are in a horizontal plane coincident with the median plane of the base or close to it.
- phase shift device constituted by a rotary actuator, the body or the rotary element of which is directly coupled to one of the unbalanced shafts, at least one other unbalanced shaft being coupled to the rotary element or to the body of the cylinder, respectively, by a pulley and belt transmission.
- Figure 1 is a vertical sectional view of a vibrating cone crusher produced in accordance with the invention.
- FIG. 1 is a sectional view of a rotary actuator constituting the phase shift device of the vibration generator system.
- the crusher shown in FIG. 1 comprises a chassis 10 constituted by a bottomless tank 12, of circular section and with vertical axis, provided with a base 14, and by a skirt 16 fixed under the base, at the edge of it. this.
- the skirt rests on the foundations by means of rubber damping pads 18 which support the crusher. Weights 79 can be attached under the skirt.
- a ring 22 is mounted coaxially inside the tank. It constitutes an interchangeable wear part which is held in the tank by a flange and bolts.
- the element 24 called "cone”, which cooperates with the ring 22, is in fact constituted by a wearing part 28 whose general shape is that of a truncated cone of variable slope, mounted on a support 30 of same shape and maintained on it by a flange and screws; it is surmounted by a hat 32.
- the cone is mounted on a shouldered sleeve 34 by means of rolling bearings so that it can rotate freely around its axis.
- the sleeve 34 is itself slidably mounted on a stepped shaft 38.
- the vertical axis common to the cone, the sleeve and the shaft coincides with the axis of the ring 22 when the mill is at rest.
- Seals are placed between the sleeve and the shaft, above and below the shoulders, so that a sealed chamber 40 is formed between the latter.
- a channel 42 drilled in the shaft makes it possible to connect this chamber to a source of pressurized liquid. By admitting liquid into the chamber or by evacuating it, the height position of the cone relative to the ring is modified and, consequently, the particle size of the ground product.
- the support 44 of the cone consists of a hub 46 in which the shaft 38 is fitted and a ferrule 48 connected to the hub by vertical ribs 50; the space provided between the hub and the ferrule allows the evacuation of the ground material. It is suspended from the chassis 10 by means of connecting rods or tie rods 52, the ends of which are connected by articulations to the base 14 of the chassis and to an annular plate 54 secured to the ferrule 48.
- a single tie rod has been shown on the drawing but it is obvious that the mill has several tie rods, for example four, regularly distributed around the axis of the mill.
- the plate 54 is also linked to the skirt 16 by rubber damping pads 55 which take up at least part of the weight of the cone and its support.
- the seal between the chassis 10 and the support of the cone 44 is ensured by a metal skirt 51 and a deformable seal 53.
- the seal between the support 44 and the sleeve 34 is ensured by a deformable seal 57.
- the shredder's vibration device consists of several vertical unbalanced shafts 56 mounted on the chassis 10; only one of them has been shown in the drawing.
- Each shaft 56 is mounted on the base 14 by means of rolling bearings and comprises two unbalanced 58 disposed on either side of the base; thanks to this arrangement the forces exerted by the unbalances on the chassis 10, when the shafts 56 are rotated, are located in a horizontal plane PP which is very close to the median plane of the base and could be confused with the latter .
- One of the unbalanced shafts is coupled, by means of a double gimbal extension, to a motor shaft 60; the other unbalanced shafts are driven from the first by a mechanical transmission system with pulleys and belts which is incorporated with a phase shift device making it possible to adjust the angular offset of a group of unbalanced shafts relative to the others to modify the amplitude of the result of centrifugal forces generated by the rotation of the unbalanced shafts.
- a mechanical transmission system with pulleys and belts which is incorporated with a phase shift device making it possible to adjust the angular offset of a group of unbalanced shafts relative to the others to modify the amplitude of the result of centrifugal forces generated by the rotation of the unbalanced shafts.
- the crusher comprises four vertical unbalance shafts arranged at the vertices of a square as described in document WO-A-9421380.
- the unbalanced shaft diagonally opposite the shaft to unbalanced 56 directly coupled to the motor shaft 60 is rotated by means of a belt 63 passing over pulleys 64 keyed on these two unbalanced shafts and on idler pulleys mounted idly on the other two unbalanced shafts.
- the rotary actuator shown in FIG. 2 comprises a cylindrical body 69 closed at its ends by bottoms 70 and 71.
- a shaft 72 is arranged coaxially in the body of the actuator; it crosses the bottom 70 in which it is mounted by means of a bearing which is capable of taking up the axial forces to which the shaft can be subjected to prevent its axial movements relative to the body of the jack.
- a socket 73 is keyed onto the shaft.
- a piston 74 is mounted in the body of the jack; it comprises a skirt housed between the wall of the body of the jack and the bush 73.
- a roller 75 mounted on an axis fixed on the body of the jack is received in a helical groove 76 machined on the piston so that any axial displacement of the piston in the cylinder body is accompanied by a rotation of the piston relative to the latter.
- a roller 77 mounted on an axis fixed on the skirt of the piston is housed in a helical groove 78 machined in the sleeve, so that any axial movement of the piston in the body of the jack causes the shaft 72 to rotate
- the directions of the grooves 76 and 78 are chosen so that the rotations of the piston and of the shaft are added.
- the cylinder body is fixed on the sleeve 67 and the outer end of the shaft is fitted into a bore in the shaft 56 and keyed onto the latter.
- the cylinder is supplied with pressurized oil via a rotary joint and through a three-position valve which supplies one or other of its chambers, to rotate the shaft 72 in a either way, and. to isolate the two chambers by maintaining the oil under pressure therein to prevent any rotation of the shaft relative to the body of the jack and to make it integral with the latter.
- the valve In operation, the valve being in the locked position (isolated cylinder chambers), all the unbalanced shafts are rotated at the same speed and the amplitude of the resulting vibration force depends on the relative angular positions of the unbalanced shafts.
- the shaft 72 of the jack is controlled by means of the valve, which causes a relative rotation of the two shafts of one group with respect to those of the other; this setting can be made on the fly.
- a feed hopper 62 is fixed to the tank 12.
- the different parts of the crusher are dimensioned so that the center of gravity of the assembly constituted by the chassis 10 and the members that it supports, in particular the ring 22 and the unbalanced shafts 56, and the center of gravity of the cone 24 and its support 44 are in the plane of the vibratory forces PP or in the immediate vicinity of this plane. It is, in particular, by suitably choosing the dimensions and the mass of the skirt 16, the weights 79 and the cap 32 that this condition is achieved. More precisely, these centers of gravity remain inside a virtual sphere centered on the point 0 defined by the intersection of the vertical axis of the cone with the plane PP when the device is at rest, and whose diameter is equal to 15% of the maximum diameter D of the cone, for all operating conditions of the mill.
- the maximum diameter D is that of the useful part of the cone, that is to say of the part which is actually used for grinding.
- the cone can extend downwards by a portion of diameter greater than D which should not be taken into account.
- Other provisions could be adopted to support the mill.
- One could for example rest the support of the cone on the ground or the foundations, by means of elastic shock-absorbing pads, the chassis and its load resting either directly on the ground or the foundations, as in the embodiment described above. above, either on the support of the cone, by means of studs similar to studs 18 or 55.
