Description

rectangular knives for cutting the material and having partitions mounted with a gap to the base perpendicular to the direction of movement of the product, while the grinding bodies are made of food rubber. .

FIG. 1 is a schematic diagram of the apparatus for grinding materials dissimilar in structure in FIG. 2 is a diagram of the knife grid; Fig. 3 is a diagram of the mutual arrangement of the knives.

A device for grinding materials of a heterogeneous structure consists of a hopper 1, a knife grid 2, on which elastic balls made of food rubber 3 are located. The bunker 1 with a knife grid 2 is rigidly fixed on frame 4, which rests on elastic spring 5. Vibration frame 4 it is communicated by a vibrodrive b connected via a belt drive 7 with an electric drive 8. Gutters 9 and 10 are rigidly attached to frame 4, and mesh partitions 11 are fixed to frame 4 inside the bunker 1 with a gap to the blade grille 2.

Knife lattice 2 is assembled from thin knives 12 and 13, inserted one into the other at half the height and creating square cells 14 (Fig. 2 and 3).

The proposed apparatus for grinding dissimilar materials works as follows.

Dry tea through the hopper 1 enters the surface of the knife grid 2, where elastic balls 3 are located. Dry tea, falling on a vibrating knife grid 2, together with elastic balls 3, is brought into a vibratory state, and the vibrator, creating a directional vibration, provides directed movement of the tea mass. By moving the knife grid 2 and experiencing the blows of the balls 3, the dry tea is ground with the help of the edges of the knife grid, and also broken under the blows of the balls when they collide with one another and vibro-hopping.

The mass of elastic balls is chosen so that their blows provide for cutting and grinding only the leaf mass of tea, which has a low stiffness coefficient, and coarse impurities that have a rigidly cellular structure are not subjected to cutting and are easily separated from the total mass with further processing during dry sorting cha The ground tea passes through the cells 14 of the knife grid and leaves the machine through the chute 9, and coarser unground impurities leave through the mesh partitions 11 and the chute 10. The elastic balls 3 are retained on the surface of the knife grid by mesh partitions 11 installed over the knife grid 2 with a gap whose size is less than the diameter of the balls 3.

At the last stage of processing low-grade gathering fractions of tea, obtained as production residues, a pressed sieve can be used as a working body instead of a knife grid (GOST 217-70 or wire mesh (GOST 2715-44)

The use of the proposed device for grinding materials of a heterogeneous structure provides an increase in the throughput of the sorting section of the tea factory, reduces the yield of low-grade products, improves the appearance of tea and its granulometric composition, and increases labor productivity.
