SU1247301A1 - Vertical roller press for briquetting loose material - Google Patents

Description

The invention relates to mechanical engineering and can be used in ferrous and non-ferrous metallurgy.

The aim of the invention is to increase the productivity and quality of the briquettes obtained by increasing their equal density.

Figure 1 presents the roller press, a General view; in FIG. 2, a replaceable vibroelement, side view.

The press consists of identical counter-rotating rolls 1 and 2, hopper 3, vibro-elements with a drive 4. The vibro-elements are made in the form of removable polka frames 5 mounted on a common base 6.

The press works as follows.

The bulk material from the hopper 3 enters the compaction zone, where rollers 1 and 2 are compacted to form briquettes. Frames 5, having made a vertical vibration movement, lower bevels pre-compact the material on the surface of the rolls with a corresponding degree of production.

water press. A part of the material, falling into the space between the frames 5 during their vibration movement, is compacted by the lower surfaces of their upper bevels and, due to the forces of friction in the material, prevents the material from being displaced from the briquetting zone in the opposite direction of its supply. This part of the material is poured into the briquetting zone, and it is replaced by a new material from the bunker. At the same time, hollow open frames contribute to the overall flow of material along the rolls from the zone of greater compaction (in the middle of the rolls) to the zones of lesser compaction (edge parts of the rolls) by equalizing the density of briquettes along the length of the rolls and at the same time increasing the quality of briquettes.
