Abstract

The invention relates to a device for crushing and is an improvement of the invention according to the author. St. 9 982791. The invention improves the efficiency of the crusher rotors by ensuring uniform rix loading. The crusher consists of a vertical rotating bunker I, the bottom 2 of which is made in the form of two oppositely located segments, with windows 4. Under the windows 4 there are two hammer rotors interacting with opposing combs 8 and decks, while the length of the hammers in each rotor is increased, starting from the respective guide plate 7 attached to each sector of the bottom. 2 Il. m

Description

"one

The invention relates to a device for grinding stem materials, in particular roughage, can be used in the agricultural, building industry and other industries and is an improvement of the basic invention in the author. No. 982791,

The purpose of the invention is to improve the efficiency of the rotors by ensuring uniform loading.

FIG. 1 shows a crusher for feed, general view; on fit, 2 - view A in figure 1,

The crusher consists of a vertical bunker 1 mounted rotatably on the bottom 2. The latter is made in the form of two oppositely located segments fixed on the body 3 of the crusher, in which two feeding windows 4 are made. Under the bottom 2 in the body 3, two hammer hammers are installed in parallel the rotor 5 with the possibility of inserting the hammers 6 over the feeding windows 4. In this case the hammers 6 in each subsequent row of the rotor 5 are filled with increasing in length, starting from the corresponding guide plate 7 fixed on top of the bottom 2, i.e. In the package (on the same axis of suspension) the next hammer is longer than the previous hammer, counting from the center of the rotor, 5 "Feed windows 4 for carrying out the process of cutting the feed during grinding are equipped with anti-ribs 8, and rotors 5 under the bottom 2 are covered with decks 9. The hopper 1 is driven, for example,

from a gearmotor via a pneumatic wheel 10. A conveyor belt is installed for shipping chopped feed.

Crusher works as follows.

The feed to be ground is loaded into the rotating hopper 1 and drawn into a circular motion. The guide plates 7 provide the material to the feed ports 4 in the direction axial to the rotors 5. Upon arrival at the rotor 5, a portion of the material is captured by the first row of hammers. 6 with a minimum length. Then, as the material moves along the rotor, the hammers of the second row come into operation, and so on. A uniform loading of the rotor occurs throughout its length, due to the fact that the supply of material to each subsequent row of hammers of the rotor 5 is carried out independently of the operation of the hammers of the previous row, the feed captured by the hammers 6 is crushed due to impact and cutting when they interact with the contradictory combs 8 and decks 9. The ground product enters the conveyor 11 and is discharged for unloading.
