Description

one

The invention relates to a device for crushing materials, namely, milk crushers, and can be applied in the milling industry.

Known hammer crusher on DOS. auth. St. 282 O42, comprising a cylindrical crushing chamber with an inlet throat, made: in the form of successively arranged decks and sieves around the circumference, and a vortex chamber having the shape of a half-cylinder flj is formed between the throat and sieve.

With this crushing chamber design, there is a significant unevenness in the wear of the hammers in the row, and the extreme hammers in the row wear out more intensively than the average ones.

The purpose of the invention is to ensure uniform wear of the crusher hammers across the width of the grinding chamber.

This goal is achieved by the fact that the vortex chamber is equipped with guide plates installed on both sides of the crushing axis of symmetry.

the camera and forming between them an acute angle with the apex directed in the direction of rotation of the rotor, the guide plates being installed at an angle of 2-4 to the transverse axis of symmetry of the breaking chamber.

FIG. 1 shows a hammer crusher in the section; in fig. 2 is a view along arrow A of FIG. one.

The hammer mill includes a crushing chamber 1, consisting of deck 2, sieve 3, vortex chamber 4, which is equipped with two or more guide plates 5 installed on both sides of the transverse axis of symmetry

the camera and forming with it acute angles in the range O-4O input 6 and output 7 of the mouth and hammer rotor 8.

Claims (2)

Crusher works as follows. Dried herbs for chaffing or common product are sucked in through the throat 6 into the crusher chamber and the impact of the rotary hammer 8 rotor 8 on the deck, where the material enters the sieve 3, the fine fraction is carried by air from the chamber to the outlet system flour through the throat 7, and the non-passing through the sieve of the material is directed into the vortex chamber 4, whirling and directed to the rotary hammer with the rotor 8 | which are additionally crushed. The guide plates 5 installed in the vortex chamber 4 direct the material flow from the edges to the center of the rotor, helping to equalize the load on the hammers, thereby ensuring equal wear of the hammers across the width of the rotor. Additionally, the ground mass is mixed with the new one and the cycle is allowed to move. The use of guide plates makes it possible to achieve uniform wear of hammers across the width of the grinding chamber, thereby increasing the time to one edge of the hammer from 9O to 14O-15O tons. Invention 1, Hammer Crusher according to the author. St. Ms 282042 is distinguished by the fact that, in order to uniformly wear the trowels, the vortex chamber is equipped with guide plates mounted on both sides of the transverse axis of symmetry of the crushing chamber and forming an acute angle between them with the apex pointing in the direction of rotation of the rotor. 2. Hammer crusher according to claim 1, characterized in that the guides: the plates are set at an angle of 2-0 to the transverse axis of symmetry of the grinding chamber.
