Description

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

The purpose of the invention is to increase productivity and improve the quality of the resulting briquettes.

Figure 1 shows a roller press General view; in FIG. 2 - section aa in figure 1; in Fig.Z - section bB in Fig.1; figure 4 - section bb in figure 1.

The roller press consists of two counter-rotating rolls 1 and 2 of a groove profile mounted on a bed (not shown) with forming cells 3 on their ridges, a loading device 4 in the form of a hopper, a profiled roll 5 of a preliminary seal, a partitioned rotary shutter 6, sections of which are mounted in circular guides 7, with the possibility of fixing the position of each of them, an adjustable profile wiring 8 mounted in the guides 9. The pre-seal roll 5 and the wiring 8 are made with a profile which protrudes the profile of the roll 2 and is the reciprocal profile of the roll 1. The roll 5 of the preliminary seal is mounted with the possibility of vertical controlled movement in the guides 10.

Press works as follows.

The powdered material is captured and pre-compacted by a roll 5, and in the form of a curved tape of the corresponding profile is fed with support 8 to the work rolls 1 and 2. Work rolls form briquettes. By moving the roll 5 of the preliminary seal in the guides 10 of the mouth, the amount of material captured by the roll and, consequently, the productivity of the press are deposited. The position of the wiring 8 in the guides 9 is selected corresponding to the position of the roll 5, so that the tape formed by the rolls 1 and 5 is not destroyed.

The presence of a profiled pre-compaction roll ensures the preparation of the material for final briquetting without 20 redistributing it during briquetting, which ensures a uniform flow of material across the width of the rolls 1 and 2. This increases the uniformity and, therefore, 25 the quality of the briquettes, increases productivity. The smoothness of the flow of material can be further improved by selecting the position of the sections of the shutter 6 according to the results of 30 trial briquetting.

The implementation of the roll 5 drive increases. intensifies the flow of material to rolls 1 and 2 and further increases productivity35.

The economic effect of the implementation of the invention is ensured by increasing the productivity and quality of briquettes.
