Description

The invention relates to structural elements of devices for grinding materials.

The closest technical solution to the proposed one is the rotor of the grinder, including two 5 vertically arranged one against the other disk with fingers installed in concentric rows £ 1].

The disadvantage of this rotor is its low efficiency.

The purpose of the invention is to increase the efficiency of the rotor and simplify its maintenance.

This goal is achieved by the fact that in the rotor of the grinder, which includes two vertically opposed disks with fingers arranged in concentric rows, the surfaces of the disks facing each other are made with a sharpening in which a clamping disk with annular projections inclined to its surface in front of each row of fingers, the free ends of the fingers being interconnected by means of a flexible connection.

In FIG. 1 shows a chopper rotor, general view; in FIG. 2 is a section AA in FIG. 1 ‘, in FIG. 3 - node I 30 in FIG. one.

The chopper rotor has a hub 1, a bearing disk 2 with a sharpening 3, a clamping disk 4, made in front of each concentric row of fingers 35 of the other rotor with annular protrusions 5, inclined to the surface of the disk 4, and fingers b connected to a flexible connection 7. The fingers have heads 8, which can 4Q (be of various shapes. Through the heads, the fingers are pressed against the carrier disk 2 by means of the pressure disk 4 with bolts 9.

The chopper rotor is barely working.

The crushed product is fed into the inter-rotor space in the direction of arrow B and moves along the outer planes of the pressure discs 4 through the fingers rotating in opposite ’'sides

6. At the same time, its grinding occurs. Inclined annular protrusions 5 discard the product to be ground from the planes of the pressure plates 4, thereby protecting them from abrasive wear and excluding the product from falling into the / gaps between the ends of the fingers 6 and the planes of the pressure plates

4. Thus, grinding of the embryo due to the abrasion effect does not occur.

The protrusion formed by the sharpening 3 and the clamping disk 4, prevents the product from entering the gap B (between the carrier and the clamping discs). This} excludes settling under the action of centrifugal forces of the smallest particles of the product between the rotor disks and the appearance of unbalanced masses during operation that cause the device to vibrate.

Since the fingers are pinched at one end between the carrier and the pressure disk, and their ends are connected by a cable that works in tension (like stretching) and prevents the fingers from bending under the action of centrifugal forces, therefore, they will experience less stress, and their durability will be more. Since the fingers are planted in the clamping disk with a slight interference fit, the time for their replacement is significantly reduced and is 20-30 minutes per rotor.

The use of the specified rotor of the grinder can improve the efficiency of its work
