Description

one

Vibratory jaw crushers and devices for grinding various rocks and materials are known, which contain two movable cheeks with vibrators, a support frame and elastic elements.

The purpose of the invention is to increase the efficiency of grinding and the efficiency of crushers.

To do this, an intermediate plate is mounted in the working cavity between the movable cheeks, the configuration of which is identical to the configuration of the working cavity, the intermediate plate being vibration-insulated from the crusher's nodes.

This makes it possible to increase the volume of simultaneously crushed material, to reduce the loss of shock impulses and the slippage of crushed harnesses relative to the crushing organs and adjacent granules.

FIG. I shows the proposed crusher, side view; in fig. 2 is a diagram of the passage of granules through the working cavity. I The crushed cheeks X of the crusher are fixed to the support frame 3 by means of packages of elastic springs 2, made of shock absorbers 4 from the base 5, the cheeks are carried by the vibrators 6, and the supporting frame by the side lining 7 of the working cavity. In the working cavity of the crusher, the crushing surfaces 8, 9 of the cheeks are in contact with the intermediate plate 10 along its facets II, 12. The intermediate plate is supported by a spring 13,

Crusher works as follows.

Due to the rotation of the unbalance of the crusher's cheek, periodically and at the same time impacts on the intermediate plate; after each impact, they are discharged, forming two chambers filled with granules from the feed tank 14. Grinding of the granules, the final degree of which is determined by the frequency of impacts and the height of the working cavity, is carried out in two parallel streams, which are basically above another grade nud, since the imposition of a series of two granules, as in node 15, or three or more, as in node 16, is unlikely. The subject of the invention is a vibratory jaw crusher for grinding granules, which contains two movable cheeks with vibrators, a support frame and elastic elements, characterized in that, in order to increase the efficiency of grinding and efficiency. crushers, in the working cavity, an intermediate plate is mounted with cheeks, the amount of which is identical to the configuration of the working cavity, with the intermediate plate vibro-insulated from the crusher's nodes.
