Description

The invention relates to grinding, in particular to centrifugal mills for medium crushing of root crops with solid impurities, and can be used in agriculture, the food industry 2

and in other industries where the processing of root crops with solid inclusions is required. The purpose of the invention is to increase the productivity of the mill. The centrifugal mill contains a cylindrical body 1, the lower part of which is made in the form of two coaxially direct helicoids 5, the direction of which turns opposite to each other. The source material with solids through the pipe 3 is fed to the rotor, slides along the accelerating blades 10 and collides with the separator 11. The material to be ground is cut through one of the separators 11 and is thrown onto the baffle plate 6, crushed and unloaded through the pipe 7. Solid inclusions when colliding with the separator 4 covers 2 are deflected by rubber and, having bounced off it, enter the collection and are discharged through the pipe 8 from the mill. 2 Il.

The invention relates to grinding, in particular to centrifugal mills for medium grinding of root crops with solid impurities, and can be used in agriculture, food and other industries that require processing of root crops with solid inclusions.

The purpose of the invention is to increase productivity.

FIG. 1 shows the proposed centrifugal mill; in fig. 2 is a view A of FIG. one.

The mill consists of a cylindrical body 1, a lid 2 with a discharge funnel 3. The inner surface of the lid is gummed with rubber 4. The lower part of the mill 1 is made in the form of two straight helicoids 5 placed between each other by a fender plate 6, the direction of the turns of which is opposite to each other. Both the helicoid unloading end spigots _ finished product 7 and for solid included ² cheny 8. Inside the housing is mounted a rotor consisting of disc 9, the acceleration vanes 10 and the separators 11.

Centrifugal mill operates as follows. 2

The source material together with solids (impurities) through the loading pipe 3 is fed to the rotor rotating at a certain speed. The crushed material together with solid inclusions in the process of acceleration slide along 2

accelerating blades 10, collide with separator 11. At the same time, the material being milled due to the fact that it has less strength than solid inclusions is cut through by one of the separators 11 and is thrown onto the demolition plate 6, crushed and discharged from the mill through the discharge nozzle of the finished product 7. At the same time, solid inclusions, when colliding with a separator, deviate from the axial trajectory upwards, collide with internal rubber gummed 4 of the cover 2 and, jumping away from it, enter the collection of solid inclusions and unload from the mill through pipe 8.

Claims (1)

Claim A centrifugal mill containing a cylindrical body with a lower part in the form of two coaxial straight helicoids with coils directed oppositely to each other and having discharge nozzles, an annular baffle plate placed in the body and a rotor mounted in it in the form of a disk with accelerating blades and plate separators, distinguished by that, in order to improve performance, the baffle plate is installed between helicoids, and the separators are made in the form of a series of plates, each of which is 2-4 times shorter than the distance from it to the nearby accelerating blade.
