Definitions
- the present invention relates to a system for fixing the movable jaw of a grinder, cone or gyratory.
- Cone crushers and gyratory crushers are intended for mining or quarrying installations and are used to reduce the size of aggregates and ores to dimensions required for their subsequent use.
- They include a frustoconical grinding tank, the wall of which supports a fixed jaw, and a conical head carrying the movable jaw mounted on a shaft coaxial with the tank.
- the geometrical axis of the conical head makes at the top of this, a certain angle with the axis of the main shaft, which gives the head, when the eccentric turns, a nutation movement.
- the materials are gradually crushed until reaching the dimension of the smallest space r between the fixed jaw and the movable jaw, at the base of the nutation head and located in 2 in the figure 1 showing a cone crusher.
- the cone crusher according to Figure 1 includes a feed hopper 8 located above the opening 1 of a grinding chamber or tank 3.
- the grinding head 5 is supported by a shaft 10 above d 'a bearing thereof, with its geometric axis making, thanks to an eccentric 12, an angle ⁇ with the axis of the shaft so as to have a nutation movement when the eccentric 12 rotates.
- the fixed jaw 11 is fixed under the opening 1, to the upper part of the tank 3.
- the movable jaw 4 is mounted on the head 5 and rests in the lower part on the head 5, while it is tightened in the upper part on the head by a screw 6, by means of a ring 7. This tightening is produced by a component of the tightening force of the screw 6 directed along the generatrix of the cone of the movable jaw 4.
- the parts which wear out the fastest are the jaws and in particular this movable jaw 4. Therefore, it must be changed periodically after wear.
- the life of the jaw 4 may not exceed a few tens of hours.
- this lifespan can go up to several years.
- this screw 6 is removably attached to the head by means of the screw 6.
- the tightening of this screw 6 requires a very high force in order to prevent the jaw from beating on the head.
- the movable jaw 4 tends to turn on the head but, by this movement, it drives the screw 6 which self-tightens while holding the jaw.
- the self-tightening of the screw means that disassembly also requires the application of a very high force.
- a ring 7 is interposed between the screw head and the upper edge of the movable jaw. For disassembly, this ring is cut with a torch and released with an appropriate tool, which frees the screw which can then turn freely.
- the fixing system comprises a locking element, the diameter of which is at least equal to that of the top of the cone of the movable jaw , which is provided with holes distributed over its periphery, into which are threaded screws which are screwed into threads located in the head or a part integral with the latter.
- the blocking element is constituted in two parts, by a blocking plate provided with holes distributed on its periphery and a blocking pin located below, screwed in a axial tapping of the head and integral in rotation with said plate, the tightening being effected by means of screws passing through the holes of the plate and being screwed into the threads formed in the locking stud.
- the blocking element is constituted by a blocking washer provided with holes distributed over its periphery; a clamping nut, screwed onto the shaft above the head and integral in rotation with said blocking washer, the clamping being effected by means of screws passing through the holes in the blocking washer and being screwed into tapped holes in said tightening nut.
- the invention provides in a system that said element, has on its outer periphery notches directed radially outward and regularly distributed over said periphery and that the movable jaw has, on its inner periphery, at the level of its opening of the pins directed radially inwards, regularly distributed over said periphery and in number equal to said notches, the pins penetrating in the assembled state into said notches in order to secure the locking element and the movable jaw in rotation during the operation of the crusher.
- the number of studs and notches is preferably equal to four. It can however be lower or higher, it being understood that the number of notches is at least equal to the number of studs.
- Figure 1 A schematic section of a cone crusher according to the prior art
- Figure 2 A perspective view from above of the movable jaw according to the present invention
- Figure 3 A schematic section of the attachment of the movable jaw of a cone crusher according to the invention
- Figure 4 A sectional view along line V-V in Figure 3.
- the movable jaw 4 is disposed on the conical head 5 and conventionally rests, as shown in Figure 1, on the wide lower part of the conical head. Its tightening in this position is effected by means of a blocking element constituted by a two-part screw, a blocking plate 16 whose diameter is at least equal to the outside diameter, at its upper part, of the cone formed by the jaw 4 and a threaded stud 13 secured to the plate by screws 17.
- a protective cover 23 of the heads of the screws 17 is also provided on the blocking plate and simply fixed thereon with a screw.
- the rotation of the jaw 4, during operation, relative to the head 5, provides a self-tightening of the part 16, 13 and thus makes it possible to maintain an adequate tightening despite the wear of the jaw.
- pins 14 are provided on the internal periphery of the jaw 4 at its upper opening.
- 15 shaped notches corresponding and in equal number are formed on the periphery of the locking plate 16. Notches and tenons are regularly distributed over said peripheries so as to mesh with one another.
- the same system of tenons and notches can be applied to the gyratory crusher, to secure the clamping nut and the jaw.
- Figure 4 shows a section of the system at the opening of the cone forming the jaw 4.
- four studs and four notches are provided. But it can of course be provided a number of pins and notches lower or higher.
