Description

..

The invention relates to the crushing of rocks and materials, namely, jaw crushers of vibration action and can be used in production in the processing of building and special materials, in particular, the type of petroleum and metallurgical slag.

The purpose of the invention is to increase the compactness of the crusher design.

Fig, 1 shows the proposed crusher, side view; in fig. 2 - the same, top view.

Between fixed crusher jaws 2 attached to the crusher body 1, elastic elements 3 (a type of compressed shear rubber elements) are installed side by side with longitudinal sections 4-6 that form a lattice pack of mutually nested crushing bodies.

In this functional section 4 and 6, moving in phase as a single unit, make up the first movable cheek, and the middle section 5, moving antiphasically with respect to them, is the second movable neck.

in the general case, each of the cheeks may be multi-section, with the sections arranged symmetrically relative to the central plane with trace 7 (FIG. 2). The elastic elements 3 are mounted in the windows of the housing. Intermediate intersectional elastic elements can be mounted in the brackets 8 of the case. The front and rear crushing bodies of the sections, which form the front and rear chambers 9 and 10 of the crushing with the shackles 2, are rigidly connected by pairwise ties of the frame construction with inclined grate 11 with through vertical openings 12 of the passage of small fractions of the material. Each of the sections is equipped with an exciter 13 (in Figs. 1 and 2, a variant with four unbalance rollers 14 per second is shown; -; a day). The causative agents of the sections are kinematically connected with each other by

for example, elastic or hinged couplings, which provide the required phasing of unbalance masses with the mutual mobility of sections. Driving

the shafts 15 of the pathogens are synchronized by the mechanism 16 with the engine 17. The housing 1 is vibration-proof by means of elastic supports 18, and the production collection conveyors 19 are located under it.

During the operation of the crusher, large pieces of raw material supplied from above to the central part of the grate 11 are crushed into chambers 9 and 10 and crushed, while small pieces are spilled onto conveyors 19 through openings 12, which are crushed in the chambers after grinding. The oscillations of sections 4-6 are generated by their exciters 13, kinematically matched and connected so that sections 4 and 6 oscillate in phase, and section 5 is antiphase in relation to them. It is most advisable that the mass of each extreme section 4 and 6 be equal to half the mass of the middle section 5, or, in general, the mass of the section of one movable cheek is equal to the mass of the sections

other (antiphase) mobile cheeks.

When moving the middle section 5, for example, to the left (Fig. 2), the end sections 4 and 6 move to the right and vice versa. In the corresponding phase (Fig. 2), the material is crushed in the narrowing zones of the crushing chambers, and in the expanding zones, the crushing product flows.

Fluctuations of the cheeks provide intensive screening of the material on the grate 11 with a large fraction fed into chambers 9 and 10.

Execution of movable cheeks in the form

Mutually nested sections ensure an increase in the compactness of the crusher, in particular, a reduction in size and an increase in the technological effectiveness of the design.
