Description

The invention relates to household ’technology and is intended for grinding coffee and other grains, sugar, spices and other food products. It can also be used in other sectors of the national economy, for example, in the building materials industry, in the chemical and food industries for grinding different materials.

The aim of the invention is to increase the degree of grinding while simplifying the design.

FIG. 1 shows the proposed device for grinding bulk materials; FIG. 2 shows a grinding body in the form of a toronoid-helix *; FIG. 3 - coil coil with a cutting edge} in figure 4 flanked coil; Fig, 5 version of the spiral turns.

The device includes a housing 1c installed in it ground motor 2, the working chamber 3, the hopper. 4, the discharge pipe 5 and the grinding body 6 in the form of a toroid-helix spiral, one end of which is mounted on the shaft 7 of the electric motor 2 by means of a mounting assembly 8, and the other on the sleeve 9 of an additional support 10 by means of a mounting assembly 11.

Claims (2)

1. A DEVICE FOR CUTTING BULK MATERIALS, mainly foodstuffs, containing a working chamber, inside of which is a grinding body, made in the form of a toroid-screw ² ' spiral, one end of which is mounted on the motor shaft, '> and bootgun bunker, characterized in that, in order to increase the degree of grinding while simplifying the design, the spiral turns are arranged so that [on one side their side surfaces adjoin , their cross-section has the shape of a rectangle, and the side faces are bevels, while the other end of the helix is reinforced under the bunker on the coaxially mounted sleeve. _ 2. The device according to claim 1, which is based on the fact that teeth are made on the outer surface of each turn. ·,
