SU1491574A1 - Vibratory mill - Google Patents

Abstract

The invention relates to the grinding of rocks, materials by vibration mills (VM) in the chemical, mining, food and other industries of the industry. The goal is to increase VM performance. In the container VM mounted horizontally on the springs, the central longitudinal pipe is provided with an external auger organ, and the end walls with shields with a spiral ribbon groove (LR) around the pipe ends adjacent to these walls. The LR of each shield — convex to the center of the pipe — creates a longitudinal circulation of the working medium of the VM, while the screw body provides its transverse circulation. The spiral cavities of the LR are opposed inside the container. 2 Il.

Description

The invention relates to the grinding of rocks, materials, in particular, to vibration mills, and can be used in the production of building materials, in enrichment, in the chemical, mining, food, and other industries.

The purpose of the invention is to increase the productivity of the mill.

FIG. 1 shows the structural scheme of the proposed mill, a longitudinal section; in fig. 2 - the same cross section.

In the container 1 of the mill with elastic supports 2, comminuted material 3, grinding bodies 4 centrally longitudinally installed pipe 5, adjacent with its ends to the end walls 6 of the container.

A shield 7 is attached to each wall 6 of the plate with a spiral ribbon groove 8 around the ends of the pipe 5 with a bulge of the spiral to the center of the pipe. The latter is equipped with a screw body 9 of known construction. Container 1 carries a vibrodrive in the whtse, for example, airborne pathogens 10. Under the perforated container bottom 11 there is an unloading duct 12. A similar design can be

loading box on top. I

In the process of operation of the mill under

the action of predominantly circular oscillations of the working medium 3 and 4 in a circular circulation movement around the pipe is moved by the auger effect along it. The effect of this effect is mainly only close to the screw body.

Claims (1)

Claim A vibration mill containing a container horizontally mounted on springs with a longitudinal pipe in it and an auger organ on the pipe, characterized in that, in order to increase productivity, the container is equipped with shields attached flat to the end walls with spiral band corrugations around these adjacent to 1Q the walls of the ends of the pipe with a bulge of corrugations to the center of the latter.
