Abstract

This invention relates to roller crushers. The purpose of the invention is to improve the reliability and efficiency of the process of crushing solid materials. The raw material, entering through the upper part of the casing 1 on the crushing rolls 3, rotating towards each other, gets on the toothed abrasive disks 6 of the beam 5 and is abraded. If an unbreakable piece of material falls on the crushing rolls 3, the movable self-aligning beam 5 is lowered into elastic rubber-metal supports due to the deformation of rubber washers inside them and the passage of non-crushable material. 3 il.

Description

The invention relates to crushers of free action - for grinding materials and industrial materials, for example, for grinding various solid materials.

The purpose of the invention is to increase the reliability and efficiency of the crushing process.

FIG. 1 shows a roll saw, cross section; in fig. 2 shows section A-A in FIG. Ij in FIG. 3 - section bb in FIG. 2.

The roll crusher consists of a casing 1, in bearings 2 of which two horizontally arranged crushing rolls 3 with impact elements 4 are installed. A beam 5 is placed along the crushing rolls below and parallel to them, equipped with toothed abrasive resistant discs 6 sec. Possibility of their free rotation on the beam and also relative to each other, mounted in elastic supports, made in the form of 7 sets of rubber washers mounted in the corners. 8. In addition, the elastic supports contain thrust sleeves 9 and 10, pressure rings 11 and nuts 12. Elastic supports depends on the hardness and the crushed material is controlled quantitative dial rubber washers 8. Beam svo-, their housings 7 is mounted on the support casing 1 sites situated on the outer side of its side walls.

For the convenience of mounting two horizontally arranged crushing rolls 3, the casing 1 is provided with a split construction in the plane of the axes of the crushing rolls.

Roll crusher works as follows.

The source material through the upper part of the casing 1 is fed to the crushing rolls 3. When the rolls 3 are rotated towards each other, it is carried out. grinding of the material, in this case the non-crushed lumps fall onto the toothed abrasive discs 6 of the beam 5 and with the impact elements of the four crushing rolls 3 are crushed and abraded. The hard crushable material falling between the impact elements 4 and the abrasion-resistant abrasive-resistant disks 6 is crushed, and in the case of an unbreakable piece of material, the self-adjusting beam 5 is movable and lowered into the elastic rubber-metal supports due to the elastic deformation of the rubber washers 8, which is not crushed piece, ensuring the elimination of jamming and breakage of roll mill units.

Thus, depending on the strength of the material being crushed, the rational mode of operation of the roller crusher depends on the selection of the elasticity of the beam supports. This makes it possible to increase the reliability and efficiency of the roller crusher.
