This invention relates to a device for crushing and grinding solid materials, such as ores, waste plastics, and can. be used in other industries.

The purpose of the invention is to increase the productivity and quality of the finished product.

The drawing shows a vibration shredder, a longitudinal section.

The grinder is compacted from the housing 1, the outer splitting cone 2, and the inner hollow splitting cone 3, 15 mounted on a rack-4 by means of elastic rubber elements 5. In the housing 1 an eccentric vibration actuator 6 is mounted, the centrally located connecting rod 7 of which is elastically connected to the 20 inner a cone 3 by means of an elastic element 8. A rack 4 is made in the end part with an annular groove and rolling bodies 9 therein, by means of which the stand .425 rests on the spherical surface of the support bar 10 fixed in the housing 1. The connecting rod 7 consists of the iron links articulated by spherical hinges 11.

The grinder works as follows.

The top-loaded raw material is crushed in the annular cavity between 1-2 and 3 due to oscillations of a cone 3 mounted on a rack 4 with elastic rubber elements 5, excited by an eccentric vibration actuator 6 connected to the cone 3 of a connecting rod 7 through an elastic ; element 8. As the rubber elements 5 are inclined to the horizon, the housing 3 performs helical oscillations, including both vertical and rotatable components. 1 TOD by the action of a part of the reactive moment, the post 4 rotates on the rolling bodies 9 along a spherical surface

. points 10, which ensures a corresponding rotation of the inner cone 3. At the same time, a more uniform wear of the surfaces of 1 cix cones, preservation of their required shape, and also contributes to leaving the crushing zone of hard-to-crush bodies is achieved. Composite dSonstruktsii connecting rod 7 allows you to fix the vibration drive 6 on the housing 1.

In comparison with the known, the proposed grinder has advantages, as it allows to increase productivity, improve the quality of grinding and reliability of operation by increasing durability and preserving the geometric shape of the working surfaces of the crushing cones.
