Abstract

The invention relates to a device for grinding grain raw materials and reduces the consumption of materials and energy. The device contains a chamber 1 with a loading 2 and a discharge 3 nozzles and a working body 5 mounted for rotation in the chamber 1. Due to the fact that the chamber 1 has an air inlet 4 connected to the inlet 2, which is located tangentially to the chamber 1 and the working body 5 is installed in the chamber 1 by means of a kinematic pair having five degrees of freedom, for example , from two ball joints 8 and 9 and connecting link 10, the grain mixture is supplied to chamber 1 in the form of a grain-air flow at high speed, a swirling flow is created in chamber 1, resulting in a complex rotational movement of the working body 5, and grinding grain and by abrasion between the rotating working body 5 and the chamber 1. As a result, the energy consumption for grinding the grain mixture is reduced, and by simplifying the design, the material consumption of the device is reduced. 1 il.

(54) DEVICE FOR CRUSHING

(57) The invention relates to a device for grinding grain raw materials and reduces the consumption of materials and energy. The device contains a chamber 1 with a loading 2 and a discharge 3 nozzles and a working body 5 mounted for rotation in the chamber 1. Due to the fact that the chamber 1 has an air inlet 4 connected to the inlet 2, which is located tangentially to the chamber 1 and the working body 5 is installed in the chamber 1 by means of a kinematic pair having five degrees of freedom, for example , from two ball joints 8 and 9 and the Even 10 connecting them, the grain mixture is supplied to chamber 1 in the form of a grain-air flow at high speed, a vortex flow is created in the chamber, resulting in a complex rotational motion of the working body 5, and grinding grain occurs both from its collision with the surfaces of chamber 1 and working body 5, and by rubbing between rotating working body 5 and chamber 1. As a result, energy consumption for grinding the grain mixture is reduced, and by simplifying the design, the material consumption of the device. 1 il.

WITH

The invention relates to the grinding of materials, mainly grain raw materials, and can be used in agriculture in the feed industry.

The purpose of the invention is to reduce material consumption and energy consumption.

The drawing schematically shows the device section.

The grinding device consists of a chamber 1 with loading 2 and unloading 3 nozzles, as well as an air supply nozzle 4 and installed in the chamber 1 by means of a kinematic pair with the possibility of rotation of the working member 5. The air supply nozzle 4 is connected to the loading nozzle 2, the loading nozzle 2 has a receiving funnel 6 for entering the grain mixture from the bunker 7 into it and is located tangentially with respect to chamber J. The kinematic pair, through which the working body 6 is installed in the chamber J, has five degrees of freedom and is, for example, two ball joints 8 and 9 connected by a link 10. The inner surface of the chamber 1 and the outer - working body 6 are made, for example knurled.

The device works as follows.

Air is pumped through the nozzle 4 to the inlet nozzle 2, into which the grain mixture also flows through the receiving funnel 6 from the hopper 7. The resulting grain-air mixture from the loading nozzle 4 is fed at high speed into the chamber .1, where the particles collide with the surface of the chamber 1 and the working body 5, and part of the grain is destroyed

is. In this case, since the grain-air mixture enters the chamber 1 tangentially, the working body 5 acquires a rotational motion both relative to its longitudinal axis, and relative to the longitudinal axis of chamber 1, i.e. the working body 5 performs a complex rotational movement, as if rolling cell 1 along its inner surface, while the grain that is not crushed by the impact with chamber 1 and working body 5 is destroyed. The ground grain mixture is crushed and advanced along chamber 1 down, out through discharge pipe 3. i

Since during the processing of grain in such a device, a combined force effect exists on it, providing efficient grinding conditions, the process energy consumption is reduced. The device is structurally quite simple and intangible.
