Description

112125652

A hinged diamond-shaped mechanism, turning the carrier P. At this, the axes 13 and the rotation bodies 14 located on them move, which, rolling over the inner surface of the hollow splitting cone 3, rotate it, causing it to roll along the material being crushed.

When a metal object that is not crushed into the crushing zone is pressed, the drawing shows a pyclic scheme, 10 tones on a hollow crushing cone 3 will increase the gagging fraction of Aki.etts to the maximum permissible values

 shotgun | contains staiiiu 1, for normal operation. When exceeding

which is fixed by the failure of the cone 2, inside the maximum allowable value of the hollow crushing cone 3 is set to the load a force is generated on the surface of the core

movably on the shaft 4 of the drive. The shaft 4 of the 15 cone 3, under the action of which the lever 5 rigidly attached to it, behaves, can be moved down and

in the direction of increasing the working gap. At the same time, the crushing cone 3 rotates relative to the shaft 4 and slides down along the shaft

The invention relates to cone gyratory crushers used for crushing ores and nonmetallic materials in the industry of building materials, the mining industry, chemical technology, and power engineering.

The purpose of the invention is to improve the reliability of the crusher. By skipping un-crushable bodies at a working move. ,,

the ends of which are hinged arms of the mechanism with a swivel roller for reproducing translational movements

The contour of the mechanism is formed by a pair of levers 20 4 using the bearing 15. Simultaneously

the carrier II moves away from the working position, moving in the slider 12 and withdrawing the hinge 10 from the shaft 4, at the same time the levers b and 7 change their position so that the hinge

b and a pair of levers 7, with the levers of b s - eins poduzhchio with levers 7, and levers 7 - with a slider 8. A force spring 9 is installed between the lever 5 and the slider 8. Hinge 10

the carrier II moves away from the working position, moving in the slider 12 and withdrawing the hinge 10 from the shaft 4, at the same time the levers b and 7 change their position so that the hinge

movably connects levers b and 7 and a set-25 diamond is folded, i.e. slider 8 moving

flax on the carrier 11, on the other carrier of the carrier a slider 12 is fixed, on which a pair of levers b and 7 is mounted. The carrier 11 has axes 13 on which the rotating bodies 14 are movably mounted along the inner surface of the hollow cone 3. Hollow shot the cone 3 is mounted on the drive shaft 4 in the bearing 15, making it possible to change the relative position of the cone along and relative to the drive shaft 4. A limiter is mounted on shaft 4

16, fixed with a nut

17. The shaft is fixed relative to the frame by the stop 18.

The cone gyratory crusher operates as follows.

The shaft 4 is set in motion from the engine, rotating it rotates the lever 5 rigidly fixed on it, which leads behind the drive shaft 4, approaches the lever 5 rigidly fixed on the shaft 4, while the force shaft 9 is compressed. Removal of the cone 3 in case of overload avoids 30 crusher breakages.

Thus, the cone of the gyraccine crusher is protected against breakage when it gets into the crushing zone of the solid body.

Technical and economic efficiency of the proposed crusher complies with the elimination of emergency crusher idle time due to ingestion of non-crushable inclusions into the crushing zone. As a result, the crusher utilization factor increases. Save the reduced costs per crusher with a capacity of 100 t / h will be up to 90 thousand rubles / year.
