Abstract

FIELD: mining.

SUBSTANCE: cone crusher contains a housing with eccentric weight vibrators and a conic ring, a crushing cone located in the housing and mounted on a bed. On stands of the bed the top external crushing housing with the cone ring is installed which is fitted with rotation eccentric weight vibrators which are implemented with a possibility of rotation of eccentric weights in phase opposition with reference to rotation of eccentric weight vibrators installed on the lower external housing. The top internal cone is installed on the fixed support mounted on bearing beams.

EFFECT: crusher provides high degree of crushing and balance of forces acting on the housing.

Description

The invention relates to construction and mining equipment, and in particular to means for crushing minerals.

Known cone vibration crusher (RF patent No. 2401700, publ. 20.10.2010), comprising a housing with an external crushing cone and a spherical support for the internal crushing cone with a shaft on which an unbalanced vibrator is mounted.

The cone crusher is characterized by the complexity of the trajectory of the inner cone, resting on a spherical surface, the imbalance of the acting forces on the body, the complexity of sealing the lubricant cavities when changing the position of the cone, which makes it difficult to maintain a rational crushing mode.

Known cone vibration crusher (RF patent No. 2161071, publ. 12/27/2000) containing a cone, a ring surrounding the cone, an annular frame, a bearing ring, a vibrating device that generates circular oscillations of the ring in a horizontal plane.

The disadvantages of the known solutions are the unstable movement of the vessel with the ring with respect to the cone, caused by the presence of several vibration sources connected by a complex belt drive with friction pulleys, and, as a result, a low degree of crushing and unbalance of the acting forces on the body.

Known cone vibration crusher (RF patent No. 2234981, publ. 27.08.2004), containing mounted on a support housing with mounted on it an inner cone and covering it with a movable outer cone, equipped with an unbalanced drive.

The disadvantages of the crusher are a limited degree of crushing, the imbalance of the existing crushing forces on the body and a high degree of vibration.

Also known cone vibration crusher (RF patent No. 2292241, publ. 01/27/2007), containing an outer cone resiliently mounted on a support with driven out-of-phase self-synchronized vibrators, in which a movable inner cone and a drive are coaxially mounted.

The disadvantages of the known solutions are the insufficient degree of crushing, the imbalance of the structure along three axes and the crushing forces acting on the body, a high degree of vibration.

Known vibration crusher (USSR Author's Certificate No. 459250, publ. 02/05/1975), adopted for the prototype, containing a housing with unbalanced vibrators and a conical ring, inside which is placed a crushing cone mounted on a bed.

The disadvantages of the crusher are the limited degree of crushing, the imbalance of forces in the vertical and horizontal directions acting on the body.

The technical result of the invention is the creation of crushers, providing a high degree of crushing, the balance of forces acting on the body.

The technical result is achieved by the fact that on the uprights of the bed there is an upper outer crushing case with a conical ring equipped with unbalanced vibrators with the ability to rotate the unbalances in antiphase relative to the unbalances of the vibrators mounted on the lower outer casing, and the upper inner cone is mounted on a fixed support mounted on the supporting beams .

In FIG. 1 shows a cone vibratory crusher, consisting of: 1 - bed; 2 - supporting racks of the bed; 3 - brackets; 4 - upper unbalanced vibrator; 5 - upper outer crushing case; 6 - conical ring; 7 - upper inner cone; 8 - motionless support; 9 - upper unbalanced vibrator; 10 - elastic shock absorbers; 11 - supporting beams; 12 - lower unbalanced vibrator; 13 - elastic shock absorbers; 14 - lower outer crushing case; 15 - a conical ring; 16 - lower inner cone; 17 - lower unbalanced vibrator.

Crusher works as follows. When the vibrators 4-17 and 9-12 are started, the unbalances, which rotate in phase and synchronously, produce a centrifugal force, forcing each body to make synchronous circular movements (oscillations in the horizontal plane with full rolling of the outer cone in one period along the inner cone). Crushable material loaded into the crushing cavity of the first chamber between the casing 5 with the conical ring 6 and the cone 7, and then passing into the crushing cavity of the second chamber between the casing 14 with the conical ring 15 and the cone 16, is subjected to double crushing and is removed from the crusher. Dynamic balancing of the system is achieved by rotating the unbalances installed on the upper outer casing 5 and the unbalances installed on the lower outer casing 14 in antiphase.

Thus, the implementation of the distinguishing features ensures the fulfillment of tasks.
