Description

The invention relates to a device for grinding materials, and. specifically for hammer mills, and can be used in the agricultural, mining and other industries.

A device for grinding feeds is known, comprising a crusher with a loading nozzle connected by a closed pipeline to a separation chamber equipped with a valve 1.

However, such a device is inefficient and not efficient enough.

The closest technical solution to the present invention is a device for shredding feed, comprising a crusher with a loading nozzle, connected by a pipeline with a separation chamber, equipped with a classifying device installed at the inlet, a gate valve and a discharge screw 2.

The disadvantage of this design is its low efficiency in the separation of wet foods due to the splitting of the classifier.

The purpose of the invention is to increase the efficiency of the product separation process.

This goal is achieved by the fact that in a device for shredding feed, including a crusher with a filling nozzle, connected by a closed pipeline to a separation chamber, equipped with

10, the classifying device, the valve and the unloading screw, the classifying device are made in the form of a rotating perforated cylinder, on the outer surface of which the blades are mounted, and the unloading screw is located at the bottom of the cylinder.

FIG. 1 shows a feed chopper, total fork;

20 in FIG. 2 is a section d-A in FIG. 1 (separation chamber, top view).

The device for grinding feed consists of a housing 1, inside of which is arranged a corrugated deck 2 and a draw bar 3 with hammers 4. A hopper 5 with an adjusting gate is installed above the crusher b. The housing 1 of the discharge 7 and the returnable 8 nozzles is connected to the separation chamber 9. Inside the chamber 9 against the inlet aperture of the pressure pipe 7 on the supporting 10 and leading 11 rollers a classifier is installed in the form of a perforated cylinder 12 with blades 13, inside which passes the screw 14 for unloading the finished product. At the entrance to the separation chamber 9 before the perforated surface 12, a valve 15 is hinged. Screw 14 in the separation chamber 9, outside the cylinder 12, is equipped with a groove 16 with an enlarged rear wall 17. The cylinder 12 is bounded by a blind wall in the direction of flow. 18 sharing chamber 9 in two. The separation chamber 9 is also connected to the housing 1 in the brewery 19. The crusher works as follows: The material to be crushed from the hopper 5 through the slit formed by the adjusting slide 6 is poured together with the air into the housing 1, where it is crushed by the hammers 4 of the crushing rotor 3 and guided discharge port 7 to the inlet of the separation chamber 9. Installed at the entrance to the chamber 9 on the support 10 and the leading 11 rollers, a perforated cylinder 12 with blades 13 rotates under the action of air flow or omoschyu elec troprivoda. In this case, small dust particles pass through the perforation, while the large ones beat off and are directed down the regrinding along the return pipe 8. Inside the cylinder 12, small particles are precipitated and removed by a screw 14 installed in its lower part, which simultaneously cleans the perforation, thereby eliminating sticking of its material. Dusting the stuffy mixture through the duct 19 is directed into the body 1 of the device. improving the conditions for the input of the material into the crushing zone. To obtain the largest grinding module by turning the valve 15 to the position All the crushed material is directed to the chute 16, from where it is conveyed by the screw 14 to unloading. The presence of the partition 18 prevents the material from entering the perforated cylinder 12 zone, and the enlarged rear wall 17 of the chute 15 prevents material from passing into the duct 19, precipitating it into the auger operating zone 14. The use of this feed chopper improves the efficiency of the grinding product separation process . Claims Device for grinding feed, including a crusher with a loading nozzle, connected by a closed pipe with a separating chamber, equipped with a classifying device, gate valve and unloading screw installed at the entrance, in order to increase the efficiency of the product separation process, the classifier is made in the form of a rotating perforated cylinder, on the outer surface of which the blades are mounted, with the unloading auger located in the bottom the third part of the cylinder.
