Abstract

The invention relates to agriculture and can be used to prepare food for animals. The purpose of the invention is to increase productivity and increase reliability by preventing particles from sticking on the walls of the pipeline by providing conditions of constant pressure throughout its length. In the device for grinding feeds, including crushing 1 and separating 2 chambers connected by pipeline 3, the latter is made tapering and curvilinear along the entire length from crushing chamber 1 to separating 2, while the outer wall 6 of it is formed by a surface with a constant increase in curvature along the movement product. 1 il.

The invention relates to machines for the grinding of materials, for example, grains, and can be used in agriculture for the preparation of animal feed.

The purpose of the invention is to increase productivity and increase reliability by preventing particles from sticking on the walls of the pipeline by providing conditions of constant pressure throughout its length.

The drawing shows the proposed device.

The device consists of a crushing chamber 1 and a separation chamber 2, connected with pipeline 3. Inside the crushing chamber 1, a rotor 4 is mounted with hammers 5. Pipeline 3 has an outer wall b and an internal 7. At the bottom, pipeline 3 has an extension. The upper end of the pipeline 3 is connected by a flange to the separation chamber 2. The latter has a return air channel 8, a butterfly valve 9, a channel 10 for returning the coarse fraction to the crushing chamber and a screw 11 for draining the finished product. Above the grinding chamber 1, a source material bin 12 is connected, connected to the grinding chamber by channel 13. Pipeline 3 is narrowed and curvilinear along the entire length from grinding chamber 1 to separation 2, while its outer wall is formed by a surface with a constant increase in curvature along the way product movements

The device works as follows.

The crushed feed is fed from the hopper 12 through the channel 13 to the crushing chamber 1, where it, between the deck and the hammers 5 mounted on the rotor 4, is crushed. Basics0

part of the crushed material is ejected from the crushing chamber 1 and moves along the outer wall 6 of the pipeline 3 to the separation chamber 2, where it is divided into fractions under the action of gravitational forces and an adjustable damper. The fine fraction (finished product) is brought out of the device with the help of the screw 11, the large one directs via channel 10: - for grinding.

The implementation of the pipeline 3 is narrowed and curved along the entire length from the crushing chamber 1 to the separation chamber 2 with a constant increase in the curvature of the outer surface ensures the material to move in a constantly pressed state to the outer wall of the pipeline due to centrifugal force. Moreover, as the material moves, its velocity decreases, but since the curvature increases, conditions of constant pressure are provided; This, therefore, prevents the material from sticking on the walls of the pipeline.
